TECHNICAL FIELD
This invention relates to dry paint transfer laminates. These laminates comprise a dry paint film layer, an adhesive layer overlying one side of the dry paint film layer, and a release liner overlying the other side of the dry paint film layer.
BACKGROUND OF THE INVENTION
Conventional painting using liquid paint requires set up steps involving masking off areas not to be painted and the spreading of drop cloths. Conventional painting also requires messy clean up of brushes, rollers, and the like, the problem of spills, exposure to fumes, and delays while the paint dries. When special effects such as faux finishes are desired, additional time and effort is required to apply additional coats.
The present invention provides a solution to these problems. With the present invention it is not necessary to mask off areas that are not to be painted and it is not necessary to use drop cloths. The messy clean up of brushes, rollers, and the like is avoided. Spills and exposure to fumes are avoided. Delays waiting for paint to dry are avoided. Special effects such as faux finishes can be accomplished with a single application.

DESCRIPTION OF THE PREFERRED EMBODIMENTS
The terms “over” and “overlies” and cognate terms such as “overlying” and the like, when referring to the relationship of one or a first layer relative to another or a second layer, refers to the fact that the first layer partially or completely lies over the second layer. The first layer overlying the second layer may or may not be in contact with the second layer. For example, one or more additional layers may be positioned between the first layer and the second layer. The terms “under” and “underlies” and cognate terms such as “underlying” and the like have similar meanings except that the first layer partially or completely lies under, rather than over, the second layer.
The term “dry paint” refers to a paint composition which has been applied to a substrate and has dried or cured sufficiently so that it does not smear or smudge when touched or handled by the user. The dry paint composition may be derived from a liquid (i.e., solvent based or water based) coating or film forming composition or a hot melt coating or film forming composition. In one embodiment, the dry paint composition may be derived from a composition containing one or more volatile components (e.g., organic solvent, water, etc.) wherein the paint composition is applied to a substrate and allowed to dry to the extent that the volatile components are removed completely or sufficiently to permit the paint to adhere to the substrate and not smear or smudge when touched by the user. The term “volatile” is used herein to refer to materials that are volatile at the drying temperature and atmospheric pressure.
The term “transparent” when referring to the transparent film layer overlying one or more of the dry paint film layers of the inventive dry paint transfer laminate means that the one or more dry paint film layers can be seen through the transparent film layer. The transparent film layer may be translucent.
Referring to FIG. 1, the inventive dry paint transfer laminate, in one of its illustrated embodiments, is generally indicated by the reference numeral 100, and comprises: a dry paint film layer 110 which has an upper surface 112 and a lower surface 114; an adhesive layer 120 overlying and adhered to upper surface 112; and a release liner 130 overlying and adhered to the lower surface 114. The release liner 130 comprises: a backing liner 132 which has an upper surface 133 and a lower surface 134; a first release coating layer 135 overlying and adhered to the upper surface 133; and a second release coating layer 136 overlying and adhered to the lower surface 134. The first release layer 135 is positioned between the upper surface 133 of backing liner 132 and the lower surface 114 of dry paint film layer 110, and preferentially adheres to the upper surface 133 of backing liner 132. Thus, when the release liner 130 is peeled away from the dry paint film layer 110, the release coating layer 135 separates from the dry paint film layer 110 and remains adhered to the backing liner 132. The lower surface 137 of release layer 136 is adapted for contacting the upper surface 122 of adhesive layer 120 when the laminate 100 is wound into roll form as illustrated in FIG. 2.
Referring to FIG. 2, the dry paint transfer laminate 100 is wound into roll form with the lower surface 137 of release coating layer 136 in contact with the upper surface 122 of adhesive layer 120. The release coating layer 136 preferentially adheres to backing liner 132. Thus, when the dry paint transfer laminate 100 illustrated in FIG. 2 is unwound, the release coating layer 136 separates from adhesive layer 120 and remains adhered to backing liner 132.
The dry paint transfer laminate 100A illustrated in FIG. 3 is identical to the dry paint transfer laminate 100 illustrated in FIG. 1 except that transparent film layer 140 is positioned between dry paint film layer 110 and release coating layer 135. The release coating layer 135 is adhered to transparent film layer 140 on one side and to backing liner 132 on the other side, and is preferentially adhered to backing liner 132. Thus, when the release liner 130 is peeled away from the transparent film layer 140, the release coating layer 135 separates from the transparent film layer 140 and remains adhered to the backing liner 132.
The dry paint transfer laminate 100B illustrated in FIG. 4 is identical to the dry paint transfer laminate 100A illustrated in FIG. 3 except that printed decorative layer 150 is positioned between dry paint film layer 110 and transparent film layer 140.
The dry paint transfer laminate 100C illustrated in FIG. 5 is identical to the dry paint transfer laminate 100B illustrated in FIG. 4 except that second printed decorative layer 160 is positioned between printed decorative layer 150 and transparent film layer 140.
Additional printed decorative layers beyond layers 150 and 160 may be used. For example, the inventive laminates may contain up to about 5 or more, and in one embodiment about 3 or about 4, printed decorative layers overlying one another. The printed decorative layers may provide a desired print or design and may be applied using conventional printing methods such as gravure, flexography, silk screen ink jet, etc.
The dry paint transfer laminate 100D illustrated in FIG. 6 is identical to the laminate 100 illustrated in FIG. 1 except that release coating layer 136 is not present, and additional release liner 170 has been added to overlie adhesive layer 120. Release liner 170 comprises: a backing liner 172 which has an upper surface 173 and a lower surface 174; and a release coating layer 176 overlying and adhered to the lower surface 174. The release layer 176 is positioned between the lower surface 174 of backing liner 172 and the upper surface 122 of adhesive layer 120, and preferentially adheres to the lower surface 174 of backing liner 172. Thus, when the release liner 170 is peeled away from the adhesive layer 120, the release coating layer 176 separates from the adhesive layer 120 and remains adhered to the backing liner 172.
The dry paint transfer laminate 100E illustrated in FIG. 7 is identical to the laminate 100 illustrated in FIG. 1 except that the laminate 100E includes support layer 180 positioned between dry paint film layer 110 and adhesive layer 120.

Alternatively, water or a water-based solution may be used to form an emulsion with the binder or resin. Water-based solutions include water-alcohol mixtures, and the like. The solvent or water is sufficiently volatile so that when applied to a substrate, the solvent evaporates leaving behind the binder or resin, pigment (if used) and any other additional non-volatile ingredients.
Additional ingredients that may be used include wetting agents; plasticizers; suspension aids; thixotropic agents such as silica; water repellant additives such as polysiloxane compounds; fire retardant additives; biocides; defoamers; flow agents; and the like.
The pigment concentration for the liquid paint or coating composition used to provide the layers 110, 150, 160 and 165 may range from about 10 to about 30% by weight, and in one embodiment about 13 to about 27% by weight. The binder or resin concentration may range from about 20 to about 40% by weight, and in one embodiment about 22 to about 37% by weight. The water or organic solvent concentration may range from about 30 to about 70% by weight, and in one embodiment about 40 to about 60% by weight. The additional ingredients such as wetting agents, suspension agents, etc., may be provided at concentrations known in the art, for example, up to about 5% by weight, and in one embodiment from about 0.1 to about 5% by weight. The coating or paint compositions used in making the layers 110, 150, 160 and 165 may have a pigment volume concentration (PVC) in the range of about 5 to about 35%, and in one embodiment 10 to about 30%. The liquid paint or coating compositions used for making the film layers 110, 150, 160, 165 and 180 may be mixed using known techniques.
The dry paint film layer 110 may comprise a single coat or multiple coats of paint and is in the form of a continuous layer, while the printed decorative layers. 150, 160 and 165 may independently be in the form of continuous or discontinuous layers. When multiple coats for the layer 110 are used, each coat may have the same or a different formulation. The layers 150, 160 and/or 165 may have the same color or a different color than the layer 110. The layers 150, 160 and/or 165 may have the same color, or they may have colors that are different from each other. The layer 110 may be used to provide background color while the layers 150, 160 and/or 165 may be used to provide a pattern or design. For example, the layers 150, 160 and/or 165 may be used to provide a faux finish or a “ragging” or “sponging” look. The layers 150, 160 and/or 165 may be used to provide a desired print or design image (e.g., a flowered design) having one or multiple colors. The designs may be in the form of repeat designs or random non-repeat designs.
The transparent film layer 140 may comprise a single coating layer or multiple coats, and may comprise any of the resin materials described above. When multiple coats are used, each coat may have the same or a different formulation. The transparent film layer 140 may be extruded. Specific examples of the resins that may be used include polyvinyl chloride, and copolymers of vinyl chloride and acrylic or methacrylic acid. The transparent film layer 140 is primarily distinguishable from the dry paint film layer 110 by the fact that it is transparent or translucent. The transparent film layer 140, in one embodiment, provides enhanced scuff resistance, stain resistance and/or recoatability to the dry paint film layer or layers underlying it. Enhanced recoatability refers to the fact that the presence of the transparent film layer 140 facilitates the subsequent application of another dry paint film layer or printed decorative layer over it, or the application of conventional paint or wall coverings (e.g., wall paper) over it.
The support layer 180 may be formed from any of the binder or resin materials described above. The support layer may be formed from a solution or an emulsion and applied using any of the coating techniques described below. The support layer 180 may be extruded. The support layer 180 may contain one or more of the above-indicated pigments. In one embodiment, the support layer 180 contains sufficient pigment to provide it with a neutral color such as gray, light blue, light red, etc. The concentration of pigment in the support layer 180, when used, may range up to about 10% by weight, and in one embodiment about 6 to about 10% by weight.
The layers 110, 140 and 180 independently may contain inorganic fillers or other organic or inorganic additives to provide desired properties such as appearance properties (clear, opaque or colored films), durability and processing characteristics. Examples of useful materials include calcium carbonate, titanium dioxide, metal particles, fibers, flame retardants, antioxidant compounds, heat stabilizers, light stabilizers, ultraviolet light stabilizers, antiblocking agents, processing aids, acid acceptors, etc.
Nucleating agents may be added to one or more of the layers 110, 140 or 180 to increase crystallinity and thereby increase stiffness. The nucleating agents which may be used include mineral nucleating agents and organic nucleating agents. Examples of mineral nucleating agents include carbon black, silica, kaolin and talc. Examples of organic nucleating agents include salts of aliphatic mono-basic or di-basic acids or aryalkyl acids such as sodium succinate, sodium glutarate, sodium caproate, sodium 4-methylvalerate, aluminum phenyl acetate, and sodium cinnamate. Alkali metal and aluminum salts of aromatic and alicyclic carboxylic acids such as aluminum benzoate, sodium or potassium benzoate, sodium betanaphtholate, lithium benzoate and aluminum tertiary-butyl benzoate also are useful organic nucleating agents. Substituted sorbitol derivatives such as bis (benzylidene) and bis (alkylbenzilidine) sorbitols wherein the alkyl groups contain from about 2 to about 18 carbon atoms are useful nucleating agents. Sorbitol derivatives such as 1,3,2,4-dibenzylidene sorbitol, 1,3,2,4-di-para-methylbenzylidene sorbitol, and 1,3,2,4-di-para-methylbenzylidene sorbitol may be used. The amounts of nucleating agent incorporated into the film forming formulations may range from about 100 to about 6000 ppm of the film. In one embodiment, the amount of nucleating agent may range from about 1000 to about 5000 ppm.
One or more of the layers 110, 140 or 180 may contain a minor amount of an adhesive resin to enhance the adhesion of the layer 110 to the layer 140 and/or 180. Also, or alternatively, tie layers of an adhesive resin can be positioned between the layers 110 and 140 or the layers 110 and 180. The adhesive resin can be an ethylene/vinyl acetate copolymer such as those available from DuPont under the tradename Elvax. The adhesive resins available from DuPont under the tradename Bynel may be used.
In one embodiment, the layers 110, 140 and/or 180 are non-stretchable and non-elastic at room temperature.
The adhesive layer 120 may comprise a pressure sensitive adhesive (PSA) layer, a moisture activatable adhesive layer or a heat activatable adhesive layer. The adhesive may comprise any pressure sensitive, moisture activatable or heat activatable adhesive known in the art for use with film substrates. The adhesive layer 120 may be in the form of a continuous or discontinuous layer, and may comprise one or a mixture of two or more adhesives. The adhesive layer may be in the form of a patterned adhesive layer with a relatively strong adhesive in some areas and a relatively weak adhesive in other areas. In one embodiment, the adhesive layer provides initial tack and allows slight movement of the laminate to allow positioning adjustments prior to forming a permanent bond. In one embodiment, the adhesive permits facilitated stripping of the dry paint film layer from a substrate when use of the paint film layer is no longer desired. In one embodiment, the adhesive layer is characterized by producing only a limited amount of ooze beyond the borders of the laminate when the laminate is applied to a substrate. In one embodiment, no ooze is produced. The adhesive may comprise a rubber based adhesive, acrylic adhesive, vinyl ether adhesive, silicone adhesive, or mixture of two or more thereof. The adhesive may be applied as a hot melt, solvent-based or water based adhesive. The adhesive materials that are useful may contain as a major constituent an adhesive polymer such as an acrylic-type polymer; block copolymer; natural, reclaimed, or styrene-butadiene rubber; tackified natural or synthetic rubber; a copolymer of ethylene and vinyl acetate; an ethylene-vinyl-acrylic terpolymer; polyisobutylene; poly (vinyl ether); etc. Other materials may be included in the adhesive such as tackifying resins, plasticizers, antioxidants, fillers, waxes, etc.
The adhesives may be classified into the following categories: random copolymer adhesives such as those based upon acrylate and/or methacrylate copolymers, α-olefin copolymers, silicone copolymers, chloroprene/acrylonitrile copolymers, and the like; block copolymer adhesives including those based upon linear block copolymers (i.e., A-B and A-B-A type), branched block copolymers, star block copolymers, grafted or radial block copolymers, and the like; and natural and synthetic rubber adhesives. A description of useful pressure-sensitive adhesives may be found in Encyclopedia of Polymer Science and Engineering, Vol. 13. Wiley-Interscience Publishers (New York, 1988). Additional description of useful pressure-sensitive adhesives may be found in Encyclopedia of Polymer Science and Technology, Vol. 1, Interscience Publishers (New York, 1964).
Pressure-sensitive adhesives that may be used include the hot melt pressure-sensitive adhesives available from H.B. Fuller Company, St. Paul, Minn. as HM-1597, HL-2207-X, HL-2115-X, HL-2193-X. Other useful pressure-sensitive adhesives include those available from Century Adhesives Corporation, Columbus, Ohio.
Conventional PSAs, including silicone-based PSAs, rubber-based PSAs, and acrylic-based PSAs are useful. Another commercial example of a hot melt adhesive is H2187-01, sold by Ato Findley, Inc., of Wauwatusa, Wis. In addition, rubber based block copolymer PSAs described in U.S. Pat. No. 3,239,478 (Harlan) also can be used, and this patent is hereby incorporated by a reference for its disclosure of such hot melt adhesives.
In one embodiment, the pressure sensitive adhesives comprise rubber based elastomer materials such as linear, branched, graft or radial block copolymers represented by the diblock structures A-B, the triblock A-B-A, the radial or coupled structures (A-B)n, and combinations of these where A represents a hard thermoplastic phase or block which is non-rubbery or glassy or crystalline at room temperature but fluid at higher temperatures, and B represents a soft block which is rubbery or elastomeric at service or room temperature. These thermoplastic elastomers may comprise from about 75% to about 95% by weight of rubbery segments and from about 5% to about 25% by weight of non-rubbery segments.
The non-rubbery segments or hard blocks comprise polymers of mono- and polycyclic aromatic hydrocarbons, and more particularly vinyl-substituted aromatic hydrocarbons which may be monocyclic or bicyclic in nature. The rubbery blocks or segments are typically polymer blocks of homopolymers or copolymers of aliphatic conjugated dienes. Rubbery materials such as polyisoprene, polybutadiene, and styrene butadiene rubbers may be used to form the rubbery block or segment. The rubbery segments include polydienes and saturated olefin rubbers of ethylene/butylene or ethylene/propylene copolymers. The latter rubbers may be obtained from the corresponding unsaturated polyalkylene moieties such as polybutadiene and polyisoprene by hydrogenation thereof.
The block copolymers of vinyl aromatic hydrocarbons and conjugated dienes which may be utilized include any of those which exhibit elastomeric properties. The block copolymers may be diblock, triblock, multiblock, starblock, polyblock or graftblock copolymers. Throughout this specification and claims, the terms diblock, triblock, multiblock, polyblock, and graft or grafted-block with respect to the structural features of block copolymers are to be given their normal meaning as defined in the literature such as in the Encyclopedia of Polymer Science and Engineering, Vol. 2, (1985) John Wiley & Sons, Inc., New York, pp. 325–326, and by J. E. McGrath in Block Copolymers, Science Technology, Dale J. Meier, Ed., Harwood Academic Publishers, 1979, at pages 1–5.
Such block copolymers may contain various ratios of conjugated dienes to vinyl aromatic hydrocarbons including those containing up to about 40% by weight of vinyl aromatic hydrocarbon. Accordingly, multi-block copolymers may be utilized which are linear or radial symmetric or asymmetric and which have structures represented by the formulae A-B, A-B-A, A-B-A-B, B-A-B, (AB)0,1,2 . . . BA, etc., wherein A is a polymer block of a vinyl aromatic hydrocarbon or a conjugated diene/vinyl aromatic hydrocarbon tapered copolymer block, and B is a rubbery polymer block of a conjugated diene.
The block copolymers may be prepared by any of the well-known block polymerization or copolymerization procedures including sequential addition of monomer, incremental addition of monomer, or coupling techniques as illustrated in, for example, U.S. Pat. Nos. 3,251,905; 3,390,207; 3,598,887; and 4,219,627. As is well known, tapered copolymer blocks can be incorporated in the multi-block copolymers by copolymerizing a mixture of conjugated diene and vinyl aromatic hydrocarbon monomers utilizing the difference in their copolymerization reactivity rates. Various patents describe the preparation of multi-block copolymers containing tapered copolymer blocks including U.S. Pat. Nos. 3,251,905; 3,639,521; and 4,208,356, the disclosures of which are hereby incorporated by reference.
Conjugated dienes which may be utilized to prepare the polymers and copolymers are those containing from 4 to about 10 carbon atoms and more generally, from 4 to 6 carbon atoms. Examples include from 1,3-butadiene, 2-methyl-1,3-butadiene (isoprene), 2,3-dimethyl-1,3-butadiene, chloroprene, 1,3-pentadiene, 1,3-hexadiene, etc. Mixtures of these conjugated dienes also may be used. The preferred conjugated dienes are isoprene and 1,3-butadiene.
Examples of vinyl aromatic hydrocarbons which may be utilized to prepare the copolymers include styrene and the various substituted styrenes such as o-methylstyrene, p-methylstyrene, p-tert-butylstyrene, 1,3-dimethylstyrene, alpha-methylstyrene, beta-methylstyrene, p-isopropylstyrene, 2,3-dimethylstyrene, o-chlorostyrene, p-chlorostyrene, o-bromostyrene, 2-chloro-4-methylstyrene, etc. The preferred vinyl aromatic hydrocarbon is styrene.
Many of the above-described copolymers of conjugated dienes and vinyl aromatic compounds are commercially available. The number average molecular weight of the block copolymers, prior to hydrogenation, is from about 20,000 to about 500,000, preferably from about 40,000 to about 300,000.
The average molecular weights of the individual blocks within the copolymers may vary within certain limits. In most instances, the vinyl aromatic block will have a number average molecular weight in the order of about 2000 to about 125,000, and preferably between about 4000 and 60,000. The conjugated diene blocks either before or after hydrogenation will have number average molecular weights in the order of about 10,000 to about 450,000 and more preferably from about 35,000 to 150,000.
Also, prior to hydrogenation, the vinyl content of the conjugated diene portion generally is from about 10% to about 80%, and the vinyl content is preferably from about 25% to about 65%, particularly 35% to 55% when it is desired that the modified block copolymer exhibit rubbery elasticity. The vinyl content of the block copolymer can be measured by means of nuclear magnetic resonance.
Specific examples of diblock copolymers include styrene-butadiene (SB), styrene-isoprene (SI), and the hydrogenated derivatives thereof. Examples of triblock polymers include styrene-butadiene-styrene (SBS), styrene-isoprene-styrene (SIS), alpha-methylstyrene-butadiene-alpha-methylstyrene, and alpha-methylstyrene-isoprene alpha-methylstyrene. Examples of commercially available block copolymers useful as the adhesives in the present invention include those available from Shell Chemical Company and listed in the following Table II.

Vector 4111 is an SIS block copolymer available from Dexco of Houston Tex.

Upon hydrogenation of the SBS copolymers comprising a rubbery segment of a mixture of 1,4 and 1,2 isomers, a styrene-ethylene-butylene styrene (SEBS) block copolymer is obtained. Similarly, hydrogenation of an SIS polymer yields a styrene-ethylene propylene-styrene (SEPS) block copolymer.
The selective hydrogenation of the block copolymers may be carried out by a variety of well known processes including hydrogenation in the presence of such catalysts as Raney nickel, noble metals such as platinum, palladium, etc., and soluble transition metal catalysts. Suitable hydrogenation processes which can be used are those wherein the diene-containing polymer or copolymer is dissolved in an inert hydrocarbon diluent such as cyclohexane and hydrogenated by reaction with hydrogen in the presence of a soluble hydrogenation catalyst. Such procedures are described in U.S. Pat. Nos. 3,113,986 and 4,226,952, the disclosures of which are incorporated herein by reference. Such hydrogenation of the block copolymers which are carried out in a manner and to extent as to produce selectively hydrogenated copolymers having a residual unsaturation content in the polydiene block of from about 0.5% to about 20% of their original unsaturation content prior to hydrogenation.
In one embodiment, the conjugated diene portion of the block copolymer is at least 90% saturated and more often at least 95% saturated while the vinyl aromatic portion is not significantly hydrogenated. Useful hydrogenated block copolymers include hydrogenated products of the block copolymers of styrene-isoprene-styrene such as a styrene-(ethylene/propylene)-styrene block polymer. When a polystyrene-polybutadiene-polystyrene block copolymer is hydrogenated, it is desirable that the 1,2-polybutadiene to 1,4-polybutadiene ratio in the polymer is from about 30:70 to about 70:30. When such a block copolymer is hydrogenated, the resulting product resembles a regular copolymer block of ethylene and 1-butene (EB). When the conjugated diene employed as isoprene, the resulting hydrogenated product resembles a regular copolymer block of ethylene and propylene (EP).
A number of selectively hydrogenated block copolymers are available commercially from Shell Chemical Company under the general trade designation “Kraton G.” One example is Kraton G1652 which is a hydrogenated SBS triblock comprising about 30% by weight of styrene end blocks and a midblock which is a copolymer of ethylene and 1-butene (EB). A lower molecular weight version of G1652 is available from Shell under the designation Kraton G1650. Kraton G1651 is another SEBS block copolymer which contains about 33% by weight of styrene. Kraton G1657 is an SEBS diblock copolymer which contains about 13% w styrene. This styrene content is lower than the styrene content in Kraton G1650 and Kraton G1652.
In another embodiment, the selectively hydrogenated block copolymer is of the formula

Bn(AB)oAp 

wherein: n=0 or 1; o is 1 to 100; p is 0 or 1; each B prior to hydrogenation is predominantly a polymerized conjugated diene hydrocarbon block having a number average molecular weight of about 20,000 to about 450,000; and each A is predominantly a polymerized vinyl aromatic hydrocarbon block having a number average molecular weight of from about 2000 to about 115,000; the blocks of A constituting about 5% to about 95% by weight of the copolymer; and the unsaturation of the block B is less than about 10% of the original unsaturation. In other embodiments, the unsaturation of block B is reduced upon hydrogenation to less than 5% of its original value, and the average unsaturation of the hydrogenated block copolymer is reduced to less than 20% of its original value.

The block copolymers may also include functionalized polymers such as may be obtained by reacting an alpha, beta-olefinically unsaturated monocarboxylic or dicarboxylic acid reagent onto selectively hydrogenated block copolymers of vinyl aromatic hydrocarbons and conjugated dienes as described above. The reaction between the carboxylic acid reagent in the graft block copolymer can be effected in solutions or by a melt process in the presence of a free radical initiator.
The preparation of various selectively hydrogenated block copolymers of conjugated dienes and vinyl aromatic hydrocarbons which have been grafted with a carboxylic acid reagent is described in a number of patents including U.S. Pat. Nos. 4,578,429; 4,657,970; and 4,795,782, and the disclosures of these patents relating to grafted selectively hydrogenated block copolymers of conjugated dienes and vinyl aromatic compounds, and the preparation of such compounds are hereby incorporated by reference. U.S. Pat. No. 4,795,782 describes and gives examples of the preparation of the grafted block copolymers by the solution process and the melt process. U.S. Pat. No. 4,578,429 contains an example of grafting of Kraton G1652 (SEBS) polymer with maleic anhydride with 2,5-dimethyl-2,5-di(t-butylperoxy) hexane by a melt reaction in a twin screw extruder.
Examples of commercially available maleated selectively hydrogenated copolymers of styrene and butadiene include Kraton FG1901X, FG1921X, and FG1924X from Shell, often referred to as maleated selectively hydrogenated SEBS copolymers. FG1901X contains about 1.7% w bound functionality as succinic anhydride and about 28% w of styrene. FG1921X contains about 1% w of bound functionality as succinic anhydride and 29% w of styrene. FG1924X contains about 13% styrene and about 1% bound functionality as succinic anhydride.
Useful block copolymers also are available from Nippon Zeon Co., 2-1, Marunochi, Chiyoda-ku, Tokyo, Japan. For example, Quintac 3530 is available from Nippon Zeon and is believed to be a linear styrene-isoprene-styrene block copolymer.
The adhesive compositions may contain at least one solid tackifier resin component. A solid tackifier is defined herein as one having a softening point above 80° C. When the solid tackifier resin component is present, the adhesive compositions may comprise from about 40 to about 80% by weight of a thermoplastic elastomer component and from about 20% to about 60% by weight, and in one embodiment from about 55 to about 65% by weight of a solid tackifier resin component. The solid tackifier reduces the modulus of the mixture sufficiently to build tack or adhesion. Also, solid tackifiers (particularly the higher molecular weight solid tackifiers (e.g., Mw greater than about 2000) and those having a lower dispersity (Mw/Mn=less than about 3)) may be less sensitive to migration into the polymer film layer, and this is desirable, since migration of tackifier into the film layer 110 or 180 may cause dimensional instability.
The solid tackifier resins include hydrocarbon resins, rosin, hydrogenated rosin, rosin esters, polyterpene resins, and other resins which exhibit the proper balance of properties. A variety of useful solid tackifier resins are available commercially such as terpene resins which are sold under the trademark Zonatac by Arizona Chemical Company, and petroleum hydrocarbons resins such as the resins sold under the trademark Escorez by Exxon Chemical Company. One particular example of a useful solid tackifier is Escorez 2596 which is a C5–C9 (aromatic modified aliphatic) synthetic tackifier having an Mw of 2100 and a dispersity (Mw/Mn) of 2.69. Another useful solid tackifier is Escorez 1310LC, identified as an aliphatic hydrocarbon resin having an Mw of 1350 and a dispersity of 1.8. Wingtack 95 is a synthetic tackifier resin available from Goodyear, Akron, Ohio consisting predominantly of polymerized structure derived from piperylene and isoprene.
The modulus of the adhesive mixtures to be coextruded also may be lowered by the incorporation of liquid rubbers, i.e., liquid at room temperature. The liquid rubbers generally will have an Mw of at least 5,000 and more often at least 20,000. Incorporation of liquid rubbers in amounts of less than 10%, and even less than 5% by weight based on the overall weight of the adhesive formulation results in adhesives which is coextrudable with the polymeric film materials. The incorporation of a liquid rubber may produce an adhesive having increased tack and adhesion. Liquid block copolymers such as liquid styrene-isoprene block copolymers may be used. Examples include Kraton LVSI-101, available from the Shell Chemical Company. Another example is a liquid polyisoprene obtained by depolymerization of high molecular weight polyisoprene. An example of a commercially available depolymerized high molecular weight polyisoprene is Isolene D-400 from Elementis Performance Polymers, Belleville, N.J., and this liquid rubber has an Mw of about 20,000. Other liquid rubbers which may be incorporated into the adhesive mixture include liquid styrene-butadiene rubbers, liquid butadiene rubbers, ethylene-propylene rubbers, etc.
The adhesive layer 120 may contain one or more pigments to enhance the opacity of the paint film layers overlying it and permit the use of thinner paint film layers to achieve desired levels of opacity. Any of the pigments identified above may be used. Specific examples include titanium dioxide and carbon black. The pigment volume concentration may range up to about 10%, and in one embodiment from about 5 to about 10%, and in one embodiment about 2 to about 8%.
The adhesive compositions also may include other materials such as antioxidants, heat and light stabilizers, ultraviolet light absorbers, fillers, colorants, antiblocking agents, reinforcing agents, processing aids, etc. Hindered phenolic and amine antioxidant compounds may be included in the adhesive compositions, and a wide variety of such antioxidant compounds are known in the art. A variety of antioxidants are available from Ciba-Geigy under the general trade designations “Irganox” and “Irgafos”. For example, the hindered phenolic antioxidant n-octadecyl 3-(3,5-di-t-butyl-4-hydroxyphenol)-proprionate is available under the general trade designation “Irganox 1076”. Irganox 1010, is identified as Tetrakis (methylene 3-(3′,5′-di-tert-butyl-4′-hydroxyphenol) proprionate) methane. Irgafos 168 is another useful antioxidant from Ciba-Geigy. Hydroquinone-based antioxidants also may be utilized, and one example of such an antioxidant is 2,5-di-tertiary-amyl-hydroquinone. Light stabilizers, heat stabilizers, and UV absorbers also may be included in the adhesive compositions. Ultraviolet absorbers include benzo-triazol derivatives, hydroxy benzyl phenones, esters of benzoic acids, oxalic acid, diamides, etc. Light stabilizers include hindered amine light stabilizers, and the heat stabilizers include dithiocarbamate compositions such as zinc dibutyl dithiocarbamate.
The adhesive compositions may contain inorganic fillers and other organic and inorganic additives to provide desired properties. Examples of useful fillers include calcium carbonate, titanium dioxide, metal particles, fibers, etc. An example of a useful end-block reinforcing agent is Cumar LX509 from Neville Resins.
The barrier layer 190 may comprise any of the acrylate polymers or copolymers described above, polyvinyl alcohol, copolymers derived from ethylene and vinyl acetate, and copolymers derived from ethylene, vinyl acetate and polyvinyl alcohol. The barrier layer may comprise a polymer blend derived from polyvinyl alcohol, urethane, Cymel 385 (a product of Cytec identified as a melamine formaldehyde resin) and a polyaziridine (e.g, NeoCryl CX100 which is identified as trimethol-tris N (methyl aziridinyl) proprionate and is available from Avecia Resins), the weight ratio of polyvinyl alcohol to urethane in one embodiment being about 20:80. The barrier layer may be provided to inhibit or reduce the migration of dyes or pigments and other materials from the substrate to which the inventive laminate is applied into the dry paint film layer 110. The following examples illustrate specific coating compositions which may be used in forming the barrier layer 190:

The backing liners 132 and 172 may independently comprise paper, polymer film, or a combination thereof. These backing liners, in one embodiment, are thermally stable, non-elastomeric and non-stretchable at room temperature. Paper liners are useful because of the wide variety of applications in which they can be employed. Paper is also relatively inexpensive and has desirable properties such as antiblocking, antistatic, dimensional stability, and can potentially be recycled. Any type of paper having sufficient tensile strength to be handled in conventional paper coating and treating apparatus can be employed as the backing liner. Thus, any type of paper can be used depending upon the end use and particular personal preferences. Included among the types of paper which can be used are clay coated paper, glassine, polymer coated paper, hemp, and similar cellulose materials prepared by such processes as the soda, sulfite or sulfate (Kraft) processes, the neutral sulfide cooking process, alkali-chlorine processes, nitric acid processes, semi-chemical processes, etc. Although paper of any weight may be employed as a backing liner, paper having weights in the range of from about 30 to about 120 pounds per ream are useful, and papers having weights in the range of from about 60 to about 100 pounds per ream may be used. The term “ream” as used herein equals 3000 square feet.
Alternatively, the backing liners 132 and 172 may independently comprise a polymer film, and examples of polymer films include polyolefin, polyester, and combinations thereof. The polyolefin films may comprise polymer and copolymers of monoolefins having from 2 to about 12 carbon atoms, and in one embodiment from 2 to about 8 carbon atoms, and in one embodiment 2 to about 4 carbon atoms per molecule. Examples of such homopolymers include polyethylene, polypropylene, poly-1-butene, etc. Films prepared from blends of copolymers or blends of copolymers with homopolymers may be used. The films may be extruded in mono or multilayers.
Another type of material which may be used as the backing liners 132 and 172 is a polycoated kraft liner which is basically comprised of a kraft liner that is coated on either one or both sides with a polymer coating. The polymer coating, which can be comprised of high, medium, or low density polyethylene, propylene, polyester, or other similar polymer films, is coated onto the substrate surface to add strength and/or dimensional stability to the liner. The weight of these types of liners ranges from about 30 to about 100 pounds per ream, with about 94 to about 100 pounds per ream being useful. In total, the final backing liner 132 may comprise from about 10% to about 40% polymer and from about 60% to about 90% paper. For two sided coatings, the quantity of polymer may be approximately evenly divided between the top and bottom surface of the paper.
The backing liners 132 and 172, in one embodiment, provide structural integrity to the laminate until they are removed upon application of the laminate to a substrate. As a result of the use of either or both of these liners, it is not necessary to employ a semi-rigid or reinforcing backing sheet with the inventive laminates.
The release coating layer 135 may comprise a single coat of release coating material or multiple coats. When multiple coats are used, each coat may have the same formulation, or different formulations may be used. The release coating layer 135 may comprise any of the above indicated binders or resins which provide sufficient tack or adherence between the release coating layer 135 and either the dry paint film layer 110 (FIGS. 1 or 6–8), transparent film layer 140 (FIGS. 3–5) or printed decorative layer 165 (FIG. 9) to prevent separation of the release coating layer 135 from film layer 110, 140 or 165 during the making of the dry paint transfer laminate and normal handling of such laminate, and yet have sufficient release properties to provide for facilitated separation between the release coating layer 135 and the layers 110, 140 or 165 when using the laminate. The release coating layer 135 may comprise an alkyd resin and/or a vinyl resin cross linked with a melamine resin. The alkyd resins include resins formed by the condensation of one or more polyhydric alcohols with one or more polybasic acids or anhydrides. The polyhydric alcohols include glycerol and the polybasic acids or anhydrides include phthalic anhydride. Modified alkyds wherein the polybasic acid is substituted in part by a monobasic acid such as acrylic acid or a vegetable oil fatty acid may be used. The vinyl resins that may be used include polyvinyl chloride, polyvinyl acetate, copolymers of vinyl chloride and vinyl acetate, acrylic resins, methacrylic resins, polystyrene resins, and the like. The melamine resins include amino resins made by the condensation of melamine with formaldehyde or a compound capable of providing methylene bridges. The cross linking of the alkyd and/or vinyl resin with the melamine resin typically occurs when the release coating 135 is applied to the backing liner and dried or cured. In one embodiment, the release coating comprises on a solids basis from zero to about 80% by weight, and in one embodiment about 10 to about 30% by weight alkyd resin; from zero to about 80% by weight, and in one embodiment about 10 to about 30% by weight vinyl resin; and from about 10 to about 30% by weight, and in one embodiment about 20 to about 25% by weight melamine resin.
Release coating layer 135 may contain one or more solid particulates that project into the surface 114 of dry paint film layer 110, the surface 141 of transparent film layer 140 or the printed decorative layer 165 to provide the layers 110, 140 or 165 with a matte or flat finish. When particulates are present, the release coating layer 135 may be referred to as a matte release coat or matte release coating layer. The particulates that may be used may be any of the filler pigments described above for use in the paint film layers. Specific examples include talc and aluminum silicate. Particulates with irregular shapes (e.g., platelet shapes) may be used. By controlling the use of these particulates the surface finish of the dry paint film layer, transparent film layer or printed decorative layer may be controlled. For example, by using these particulates, the dry paint film layer, transparent film layer or printed decorative layer may be provided with a flat or semi-gloss finish. The paint film layer, transparent film layer or printed decorative layer may be provided with a glossy finish by not using or minimizing the use of these particulates. The weight ratio of particulates to resin or binder may range up to about 1.1:1, and in one embodiment about 0.7:1 to about 1.1:1, and in one embodiment from about 0.7:1 to about 0.9:1, and in one embodiment about 0.9:1 to about 1.1:1.
The release coating layers 136 and 176 may independently comprise any release coating composition known in the art. Silicone release coating compositions may be used. The silicone release coating compositions typically comprise polyorganosiloxanes such as polydimethylsiloxanes. The silicone release coating composition used in this invention may be room temperature cured, thermally cured, or radiation cured. Generally, the room temperature and thermally curable compositions comprise at least one polyorganosiloxane and at least one catalyst (or curing agent) for such polyorganosiloxane(s). These compositions may also contain at least one cure accelerator and/or adhesivity promoter. As is known in the art, some materials have the capability of performing both functions, i.e., the capability of acting as a cure accelerator to increase the rate, reduce the curing temperature, etc., and also as an adhesivity promoter to improve bonding of the silicone composition to the substrate. The use of such dual function additives where appropriate is within the purview of the invention.
In the embodiments illustrated in FIGS. 1–9, the release force required to separate release coating layer 135 from dry paint film layer 110, transparent film layer 140, or printed decorative layer 165 is advantageously greater than the release force required to separate release coating layer 136 from adhesive layer 120. In the embodiment illustrated in FIG. 6, the release force required to separate release coating layer 135 from dry paint film layer 110 is advantageously greater than the release force required to separate release coating layer 176 from adhesive layer 20. In one embodiment, the release force required to separate release coating layer 135 from dry paint film layer 110, transparent film layer 140 or printed decorative layer 165 may be in the range of about 20 to about 180 grams per two inches (g/2 in), and in one embodiment 30 to about 150 g/2 in, and in one embodiment 40 to about 120 g/2 in, and in one embodiment 50 to about 100 g/2 in, and in one embodiment 50 to about 90 g/2 in, and in one embodiment about 70 to about 90 g/2 in, and in one embodiment about 50 to about 65 g/2 in. In one embodiment, the release force required to separate release coating layer 136 or 176 from adhesive layer 120 is in the range of 10 to about 150 g/2 in, and in one embodiment about 20 to about 150 g/2 in, and in one embodiment about 20 to about 90 g/2 in, and in one embodiment about 30 to about 150 g/2 in, and in one embodiment about 30 to about 100 g/2 in, and in one embodiment about 30 to about 70 g/2 in. The test method for determining these release forces involves measuring the force required to separate a two-inch wide release coated liner from the layer 110, 140 or 165, or from an adhesive coated substrate, with the release coated liner extending at an angle of 90° relative to the layer or substrate and being pulled at a rate of 300 inches per minute. The test may be conducted at room temperature.
Each of the layers 110, 120, 135, 136, 140, 176, 180 and 190 may be independently applied and dried and/or cured using known techniques. The application techniques include gravure, reverse gravure, offset gravure, roll coating, brushing, knife-over roll, metering rod, reverse roll coating, doctor knife, dipping, die coating, slot die coating, spraying, curtain coating, slide coating, slide curtain coating, extrusion, co-extrusion, flexographic, letter press, rotary screen, flat screen, and the like. In one embodiment, the adhesive layer 120 is a pressure sensitive adhesive layer and it may be applied using transfer lamination. The decorative layers 150, 160 and 165 may be applied using known printing techniques including gravure, flexographic, silk screen, ink jet, etc. The applied layers may be dried and/or cured by exposure to heat or to known forms of ionizing or actinic non-ionizing radiation. Drying or curing temperatures that may be used may range from about 115° C. to about 160° C., and in one embodiment about 140° C. to about 150° C. Useful types of radiation include ultraviolet light and electron beam. The equipment for generating these forms of thermal or radiation drying and/or curing are well known to those skilled in the art. One or more of the layers 110, 120, 140 and 180 may be extruded. The layers 110 and/or 180 may be coextruded with the adhesive layer 120. In one embodiment, the support layer 180 may be coextruded with the adhesive layer 120, and then the dry paint film layer 110 is coated (e.g., gravure) onto the support layer 180.
Each of the layers 110, 140 or 180 may independently comprise a single layer film or a multilayer film of two or more adjacent coextruded layers. For example, the layer 110, 140 or 180 may comprise one layer of a polyolefin and one layer of a blend of a polyolefin and a copolymer of ethylene and vinyl acetate (EVA). In one embodiment, the film layers 110, 140 or 180 may comprise three layers, a base or core layer of, for example, a polyolefin, and skin layers in both sides of the base or core layer which may comprise the same or different polymer blends.
The dry paint film layer 110 or the support layer 180 may be coextruded with the adhesive layer 120 using separate extruders as illustrated in FIG. 11 or a dual die extruder as illustrated in FIG. 12. Referring to FIG. 11, release liner 200 is uncoiled from roll 240 and advanced past extrusion die 210 where it is coated with adhesive layer 120, and then past extrusion die 220 where the support layer 180 is coated onto the adhesive layer 120. The resulting coextrudate is collected in roll form as indicated by collection roll 250. Referring to FIG. 12, release liner 200 is advanced past dual extrusion die 230 which simultaneously coats release liner 200 with adhesive layer 120 and support layer 180. The resulting coextrudate is collected in roll form as indicated by collection roll 250. When a desired quantity of the coextrudate has been manufactured, the collection roll 250 is removed from the process and is stored for subsequent processing (e.g., coating, printing, etc.) during a separate operation at either the same or at a different geographic location, thereby providing enhanced manufacturing flexibility. Alternatively, rather than being collected, the coextrudate may be routed for coating, printing, etc., during the same manufacturing operation. The dry paint film layer 110 may be coextruded with the adhesive layer 120 following the above procedure. Multi-die application methods useful for applying both a pressure sensitive adhesive and a film forming layer to a substrate are further described in Published PCT International Application Nos. PCT/US95/11807; PCT/US95/11733; PCT/US95/11734; and PCT/US95/11717, which are herein incorporated by reference. The polymeric film materials and adhesive compositions that are coextruded may be neat, or they may be emulsions or solvent-based. Emulsion and solvent-based acrylic based PSAs are known and described in, for example, U.S. Pat. Nos. 5,639,811 and 5,164,444, respectively, and these patents are hereby incorporated by reference for such disclosures. When emulsions of the film materials and/or adhesive compositions are used, the water may be removed in an extruder by using the process described and claimed in U.S. Pat. No. 5,716,669 (LaRose et al). In one embodiment, the film materials and adhesives which are coextruded are compositions substantially free (e.g., less than about 1% by weight) of water and/or solvents. The presence of water or solvents during the coextrusion process may result in pinholes and bubbles in the coextruded film. The presence of voids in the film due to steam may be referred to as “moisture slits.”
When the polymeric film material and adhesive are coextruded, the hot melt viscosity of the polymeric film material and the adhesive may be within a window or range of viscosities which may produce a coextrudate of continuous and uniform layers of the polymeric film material and the adhesive in order to avoid film defects and intermingling of the polymeric film material and the adhesive during the coextrusion process. The polymeric film material may have a hot melt viscosity that is within a factor of from about 0.07 to about 15 times the hot melt viscosity of the adhesive at the shear rates incurred during the coextrusion process. The shear rates may range from about 100 sec-1 to about 10,000 sec-1. The factor may be from about 1 to about 15, and in one embodiment about 1 to about 10. It is also desirable for the polymeric film material and the adhesive to have relatively similar melt viscosities at the extrusion temperatures. For example, when the adhesive is a conventional hot melt adhesive, the extrusion temperatures of the adhesive may be in the range of from about 150° C. to about 200° C., and in one embodiment in the range of from about 175° C. to about 200° C. The polymeric film material selected for use with the adhesive may have an extrusion temperature below about 200° C., and in one embodiment in the range of from about 150° C. to about 180° C.
The dry paint transfer laminate 100 illustrated in FIG. 1 may be made by applying release coating 136 to lower surface 134 of backing liner 132 using one of the foregoing application techniques and then curing the release coating. The coat weight for the release coating layer 136 may be in the range of about 0.1 to about 1 gram per square meter (gsm), and in one embodiment about 0.25 to about 0.35 gsm. Release coating layer 135 is then applied to upper surface 133 of backing liner 132 using one of the above indicated application techniques (e.g, gravure) and then dried or cured. The coat weight for the release coating 135 may range from about 2.5 to about 6.5 gsm, and in one embodiment about 4.5 to about 5.5 gsm. The liquid paint or coating composition for forming dry paint film layer 110 is then applied to the surface of release coating layer 135 using one of the above indicated application techniques (e.g., reverse roll or slot die) and then dried or cured. The coat weight for the dry paint film layer 110 may range from about 20 to about 60 gsm, and in one embodiment about 30 to about 40 gsm. One or more coats may be applied. Pressure sensitive adhesive layer 120 is then applied to upper surface 112 of dry paint film layer 110 using one of the above indicated application techniques (e.g., slot die) and then dried or cured. The pressure sensitive adhesive may be applied using transfer lamination. The coat weight for the pressure sensitive adhesive layer 120 may range from about 10 to about 30 gsm, and in one embodiment about 11 to about 17 gsm. The dry paint transfer laminate 100 may then be wound into roll form as illustrated in FIG. 2 using known techniques.
The dry paint transfer laminate 100A illustrated in FIG. 3 may be made using the same procedure used for making the laminate 100 except that transparent film layer 140 is applied to the surface of release coating layer 135 and then dried or cured prior to the application of the dry paint film layer 110. The dry paint film layer 110 is then applied to the surface of the transparent film layer 140. The transparent film layer 140 may be applied using one of the foregoing application techniques (e.g., gravure). The coat weight for the transparent film layer 140 may range from about 1 to about 5 gsm, and in one embodiment about 2.5 to about 3.5 gsm. One or more coats may be applied. The dry paint transfer laminate 100A may then be wound into a roll as illustrated in FIG. 2 using known techniques.
The dry paint transfer laminate 100B illustrated in FIG. 4 may be made using the same procedure used for making the laminate 100A except that the liquid paint composition for forming the printed decorative layer 150 is applied to the surface of the transparent film layer 140 and then cured prior to the application of the dry paint film layer 110. The dry paint film layer 110 is then applied to the surface of the printed decorative layer 150. The printed decorative layer 150 may be applied using any of the foregoing printing techniques (e.g., gravure, flexographic, silk screen, ink jet, etc.). The coat weight for the printed decorative layer 150 may range from about 0.3 to about 2 gsm, and in one embodiment about 0.3 to about 0.7 gsm. The dry paint transfer laminate 100B may then be wound into a roll as illustrated in FIG. 2 using known techniques.
The dry paint transfer laminate 100C illustrated in FIG. 5 may be made using the same procedure used for making the laminate 100B except that the liquid paint composition for forming the second printed decorative layer 160 is applied to the surface of the transparent film layer 140 and then dried or cured prior to the application of the printed decorative layer 150. The printed decorative layer 150 is then applied over the surface of the second printed decorative layer 160. The second printed decorative layer 160 may be applied using any of the foregoing printing techniques (e.g., gravure, flexographic, silk screen, ink jet, etc.). The coat weight for the second printed decorative layer 160 may range from about 0.3 to about 2 gsm, and in one embodiment about 0.3 to about 0.7 gsm. The dry paint transfer laminate 100C may then be wound into a roll as illustrated in FIG. 2 using known techniques.
The dry paint transfer laminate 100D illustrated in FIG. 6 may be made using the same procedure used for making the laminate 100 illustrated in FIG. 1 except that release liner 170 is adhered to adhesive layer 120 with release coating layer 176 in contact with adhesive layer 120.
The dry paint transfer laminate 100E illustrated in FIG. 7 may be made using the same procedure used for making the laminate 100 illustrated in FIG. 1 except that the support layer 180 is adhered to the dry paint film layer 110. The support layer 180 may be coextruded with the adhesive layer 120 and then the dry paint film layer 110 may be coated (e.g., gravure) onto the support layer 180. The dry paint transfer laminate 100E may then be wound into a roll as illustrated in FIG. 2 using known techniques.
The dry paint transfer laminate 100F illustrated in FIG. 8 may be made using the same procedure used for making the laminate 100 illustrated in FIG. 1 except tha the barrier layer 190 is coated on the dry paint transfer film layer 110. The dry paint transfer laminate 100F may then be wound into a roll as illustrated in FIG. 2 using known techniques.
The dry paint transfer laminate 100G illustrated in FIG. 9 may be made using the same procedure used for making the laminate 100 illustrated in FIG. 1 except that support layer 180 is adhered to dry paint transfer layer 110. The support layer 180 may be coextruded with the adhesive layer 120. The printed decorative layers 150, 160 and 165 may be coated sequentially over the dry paint film layer 110. The dry paint transfer laminate 100G may then be wound into a roll as illustrated in FIG. 2 using known techniques.
The dry paint transfer laminate 100H illustrated in FIG. 10 may be made using the same procedure used for making the laminate 100C illustrated in FIG. 5 except that the release liner used in the laminate 100C is removed, and the release liner 170 and accompanying release layer are included. The dry paint film layer 110 and adhesive layer 120 may be coextruded onto the release layer 176 of the release liner 170.
The inventive dry paint transfer laminate may be made in a single production line or in multiple production lines or multiple production facilities. With multiple production lines or facilities, part of the laminate may be produced as a roll laminate, dried or cured, rolled up, transferred to the next production line or facility, unrolled, and further treated with the application of additional layers. For example, the dry paint film layer 110 and the adhesive layer 120 may be deposited in multiple lines, or they may be deposited in sequence in a single line, or they may be deposited simultaneously such as by coextrusion or multi-die coating methods. Production in a single production line may be more efficient by avoiding extra handling, storage, and transporting steps for what may comprise, at least in one embodiment, relatively thin and delicate film materials.
The dry paint transfer laminate 100 may be used by unrolling the laminate from the roll illustrated in FIG. 2, and simultaneously applying the laminate to the substrate (e.g., wall) to be covered. The substrate may comprise any flat surface. The flat surface may comprise wall board, plastic sheet, metal sheet, composites, and the like. The substrate may comprise an interior (i.e., indoor) surface or an exterior (i.e., outdoor) surface. The laminate is placed over the substrate with the adhesive layer 120 in contact with the substrate. The release liner 130 is then peeled off leaving the dry paint film layer 110 adhered to the substrate by the adhesive layer 120. An advantage of using this laminate, at least in one embodiment, is that it is possible to overlap part of the applied dry paint film layer with the next adjacent applied dry paint film layer due to the fact that the seams substantially disappear and therefore are not noticeable. This advantage is provided at least in part due to the fact that the dry paint film layer 110 is relatively thin. Also, the gloss and opacity of the dry paint film layer 110 contrubute to this ability to hide seems.
The dry paint transfer laminate 100A may be applied to a substrate in the same manner as the laminate 100. When the release liner 130 is peeled off, the dry paint film layer 110, transparent film layer 140, and adhesive layer 120 remain adhered to the substrate with the adhesive layer 120 in contact with the substrate.
The dry paint transfer laminate 100B may be applied to a substrate in the same manner as the laminate 100. When the release liner 130 is peeled off, the dry paint film layer 110, printed decorative layer 150, transparent film layer 140, and adhesive layer 120 remain adhered to the substrate with the adhesive layer 120 in contact with the substrate.
The dry paint transfer laminate 100C may be applied to a substrate in the same manner as the laminate 100. When the release liner 130 is peeled off, the layers 110, 150 and 160, transparent film layer 140, and adhesive layer 120 remain adhered to the substrate with the adhesive layer 120 in contact with the substrate.
The dry paint transfer laminate 100D may be applied to a substrate in the same manner as the laminate 100 except that the laminate is advantageously provided in the form of a flat sheet rather than a roll and the release liner 170 is peeled off before the adhesive layer 120 is adhered to the substrate.
The dry paint transfer laminate 100E may be applied to a substrate by adhering the adhesive layer 120 to the substrate, and then removing the release liner 130.
The dry paint transfer laminate 100F may be applied to a substrate by adhering the adhesive layer 120 to the substrate, and removing the release liner 130.
The laminate 100G may be applied to a substrate by adhering the adhesive layer 120 to the substrate, and removing the release liner 130.
The laminate 100H may be applied to a substrate by peeling the peeling the release liner 170 and accompanying release coating 176 from the laminate, and then applying the adhesive layer 120 to the substrate. The laminate may be applied using a specialized applicator which winds or coils the release liner 170 and accompanying release layer 176 as the remainder of the laminate is applied to the substrate.

(b) a resin and solid particulates, the weight ratio of particulates to resin being in the range of up to about 1.1:1.

53. A multi-layer laminate comprising:
a dry paint layer comprising a binder and a pigment, the dry paint layer having an upper surface and a lower surface;
a dry pressure-sensitive adhesive layer overlying the upper surface of the dry paint layer;
a support layer or a barrier layer positioned between the dry paint layer and the adhesive layer; and
a release liner overlying the lower surface of the dry paint layer, the release liner comprising a flexible polymeric carrier film having a thickness of from about 0.5 to about 2 mils and a matte release coat bonded to the carrier film and in overlying contact with the dry paint layer, the matte release coat having a hardened state at room temperature and made from a resinous material consisting essentially of (1) a matte surfacing component that forms a matte release surface, (2) an adhesion component for releasably adhering the matte release surface to the dry paint layer, and (3) a release component that releases the matte release surface from contact with the dry paint layer at room temperature to transfer a matte surface finish from the matte release surface to an exposed surface of the dry paint layer,
wherein the matte release coat comprises one or more of (a) and/or (b):
(a) a vinyl resin and an alkyd resin; and/or
(b) a crosslinked resin binder containing a dispersed inert particulate material to produce a micro-roughened matte surface to transfer the matte surface finish to the dry paint layer.

54. The multi-layer laminate of claim 53, wherein the resins in (a) are crosslinked.

55. The laminate of claim 1 wherein the dry pressure-sensitive adhesive is in contact with a substrate comprising a fiat wall surface in use.

56. A method of applying a protective or decorative coating to a substrate, comprising:
placing the laminate of claim 1 over the substrate with the adhesive layer in contact with the substrate and adhering the laminate to the substrate; and
separating the release liner from the laminate, leaving the dry paint film layer adhered to the substrate.
