     Absorption maxima at 597 nm and 622 nm were observed in the UV-visible absorption spectrum in DMF solution. 
     Example 6b 
     A portion of the sulfonamide product from Example 6a (10 g), 0.00124 mol), DMF (25 ml), hydroquinone (10 mg), DMAP (30.3 mg) and methacrylic anhydride (0.556 ml) were mixed together and stirred while triethylamine (0.520 ml) was added dropwise. The reaction mixture was stirred at room temperature for 24 hours and then drowned into water (50 ml). The solid product was collected by filtration and dried in air (yield—0.96 g, 82% of the theoretical yield). FDMS supported the following structure:                           
     An absorption maxima at 579 nm and 623 nm were observed in the UV-Visible light absorption spectrum in DMF as solvent. 
     Example 7 
     A mixture of the copper phthalocyanine compound (0.100 g, 0.0000953 mol) prepared as in Example 1 of U.S. Pat. No. 5,102,980 and having primarily the structure CuPc[SO 2 —N—CH 2 C(CH 3 ) 2 CH 2 OH] 2.5 , wherein CuPc represents the copper phthalocyamine moiety, DMF (5 ml), hydroquinone (1 mg), DMAP (2.3 mg), methacrylic anhydride (0.071 ml) and triethylamine (0.066 ml) was stirred at room temperature for 24 hours. The reaction mixture was poured into 10 ml of methanol and then water (25 ml) was added. A semi-solid, blue product resulted, which was washed by decantation and then allowed to dry in air. The product consists primarily of the copper phthalocyanine compound having the structure, CuPc[SO 2 NHCH 2 C(CH 3 ) 2 CH 2 OCO—C(CH 3 )═CH 2 ] 2.5  and produces a brilliant cyan color when dissolved in DMF.

     The thermally-stable, colored, photopolymerizable compounds which contain vinyl or substituted vinyl groups are polymerizable or copolymerizable, preferably by free radical mechanisms, said free radicals being generated by exposure to UV light by methods known in the art of preparing UV-cured resins. Polymerization can be facilitated by the addition of photoinitiators. The colored polymeric materials normally are prepared by dissolving the functionalized colorants containing copolymerizable groups in a polymerizable vinyl monomer with or without another solvent and then combining with an oligomeric or polymeric material which contains one or more vinyl or substituted vinyl groups. 
     The second embodiment of the present invention is a coating composition comprising (i) one or more polymerizable vinyl compounds, i.e., vinyl compounds which are copolymerizable with the dye compounds described herein, (ii) one or more of the dye compounds described above, and (iii) at least one photoinitiator. The polymerizable vinyl compounds useful in the present invention contain at least one unsaturated group capable of undergoing polymerization upon exposure to UV radiation in the presence of a photoinitiator, i.e., the coating compositions are radiation-curable. Examples of such polymerizable vinyl compounds include acrylic acid, methacrylic acid and their anhydrides; crotonic acid; itaconic acid and its anhydride; cyanoacrylic acid and its esters; esters of acrylic and methacrylic acids such as allyl, methyl, ethyl, n-propyl, isopropyl, butyl, tetrahydrofurfuryl, cyclohexyl, isobomyl, n-hexyl, n-octyl, isooctyl, 2-ethylhexyl, lauryl, stearyl, and benzyl acrylate and methacrylate; and diacrylate and dimethacrylate esters of ethylene and propylene glycols, 1,3-butylene glycol, 1,4-butanediol, diethylene and dipropylene glycols, triethylene and tripropylene glycols, 1,6-hexanediol, neopentyl glycol, polyethylene glycol, and polypropylene glycol, ethoxylated bisphenol A, ethoxylated and propoxylated neopentyl glycol; triacrylate and trimethacrylate esters of tris-(2-hydroxyethyl)isocyanurate, trimethylolpropane, ethoxylated and propoxylated trimethylolpropane, pentaerythritol, glycerol, ethoxylated and propoxylated glycerol; tetraacrylate and tetramethacrylate esters of pentaerythritol and ethoxylated and propoxylated pentaerythritol; acrylonitrile; vinyl acetate; vinyl toluene; styrene; N-vinyl pyrrolidinone; alpha-methylstyrene; maleate/fumarate esters; maleic/fumaric acid; crotonate esters, and crotonic acid. 
     The polymerizable vinyl compounds useful in the present invention include polymers which contain unsaturated groups capable of undergoing polymerization upon exposure to UV radiation in the presence of a photoinitiator. The preparation and application of these polymerizable vinyl compounds are well known to those skilled in the art as described, for example, in  Chemistry and Technology of UV and EB Formulation for Coatings, Inks, and Paints,  Volume II: Prepolymers and Reactive Diluents, G. Webster, editor, John Wiley and Sons, London, 1997. Examples of such polymeric, polymerizable vinyl compounds include acrylated and methacrylated polyesters, acrylated and methacrylated polyethers, acrylated and methacrylated epoxy polymers, acrylated or methacrylated urethanes, acrylated or methacrylated polyacrylates (polymethacrylates), and unsaturated polyesters. The acrylated or methacrylated polymers and oligomers typically are combined with monomers which contain one or more acrylate or methacrylate groups, e.g., monomeric acrylate and methacrylate esters, and serve as reactive diluents. The unsaturated polyesters, which are prepared by standard polycondensation techniques known in the art, are most often combined with either styrene or other monomers, which contain one or more acrylate or methacrylate groups and serve as reactive diluents. A second embodiment for the utilization of unsaturated polyesters that is known to the art involves the combination of the unsaturated polyester with monomers that contain two or more vinyl ether groups or two or more vinyl ester groups (WO 96/01283, WO 97/48744, and EP 0 322 808). 
     The coating compositions of the present invention optionally may contain one or more added organic solvents if desired to facilitate application and coating of the compositions onto the surface of substrates. Typical examples of suitable solvents include, but are not limited to ketones, alcohols, esters, chlorinated hydrocarbons, glycol ethers, glycol esters, and mixtures thereof Specific examples include, but are not limited to acetone, 2-butanone, 2-pentanone, ethyl acetate, propyl acetate, isopropyl acetate, butyl acetate, isobutyl acetate, ethylene glycol diacetate, ethyl 3-ethoxypropionate, methyl alcohol, ethyl alcohol, propyl alcohol, isopropyl alcohol, butyl alcohol, ethylene glycol, propylene glycol, ethylene glycol monomethyl ether, ethylene glycol monoethyl ether, ethylene glycol monopropyl ether, ethylene glycol monobutyl glycol, diethylene glycol monomethyl ether, diethylene glycol monoethyl ether, diethylene glycol monobutyl ether, propylene glycol monomethyl ether, diethylene glycol monobutyl ether acetate, diethylene glycol monoethyl ether acetate, ethylene glycol monobutyl ether acetate, propylene glycol monomethyl ether acetate, methylene chloride, chloroform, and mixtures thereof. The amount of added or extraneous solvent which may be present in our novel coating compositions may be in the range of about 1 to 70 weight percent, more typically about 1 to 25 weight percent, based on the total weight of the coating composition. 
     Certain polymerizable vinyl monomers may serve as both reactant and solvent. These contain at least one unsaturated group capable of undergoing polymerization upon exposure to UV radiation in the presence of a photoinitiator. Specific examples include, but are not limited to: methacrylic acid, acrylic acid, ethyl acrylate and methacrylate, methyl acrylate and methacrylate, hydroxyethyl acrylate and methacrylate, diethylene glycol diacrylate, trimethylolpropane triacrylate, 1,6 hexanediol di(meth)acrylate, neopentyl glycol diacrylate and methacrylate, vinyl ethers, divinyl ethers such as diethyleneglycol divinyl ether, 1,6-hexanediol divinyl ether, cyclohexanedimethanol divinyl ether, 1,4-butanediol divinyl ether, triethyleneglycol divinyl ether, trimethylolpropane divinyl ether, and neopentyl glycol divinyl ether, vinyl esters, divinyl esters such as divinyl adipate, divinyl succinate, divinyl glutarate, divinyl 1,4-cyclohexanedicarboxylate, divinyl 1,3-cyclohexanedicarboxylate, divinyl isophthalate, and divinyl terephthalate, N-vinyl pyrrolidone, and mixtures thereof. 
     In addition, the compositions of the present invention may be dispersed in water rather than dissolved in a solvent to facilitate application and coating of the substrate surface. In the water-dispersed compositions of the present invention a co-solvent is optionally used. Typical examples of suitable cosolvents include but are not limited to acetone, 2-butanone, methanol, ethanol, isopropyl alcohol, ethylene glycol monomethyl ether, ethylene glycol monoethyl ether, ethylene glycol monopropyl ether, and ethylene glycol monobutyl ether, ethylene glycol, and propylene glycol. Typical examples of water-soluble ethylenically unsaturated solvents include but are not limited to: methacrylic acid, acrylic acid, N-vinyl pyrrolidone, 2-ethoxyethyl acrylate and methacrylate, polyethylene glycol dimethacrylate, polypropylene glycol monoacrylate and monomethacrylate, and mixtures thereof. The amount of suitable aqueous organic solvent (i.e., organic solvent and water) in the dispersed coating compositions of the present invention is about 10 to about 90 weight percent, preferably about 75 to about 90 weight percent of the total coating composition. 
     The coating compositions of the present invention contain one or more of the thermally-stable, colored, photopolymerizable compounds described herein. The concentration of the colored compound or compounds may be from about 0.005 to 30.0, preferably from about 0.05 to 15.0, weight percent based on the weight of the polymerizable vinyl compound(s) present in the coating composition, i.e., component (i) of the coating compositions. The coating compositions of the present invention normally contain a photoinitiator. The amount of photoinitiator typically is about 1 to 15 weight percent, preferably about 3 to about 5 weight percent, based on the weight of the polymerizable vinyl compound(s) present in the coating composition. Typical photoinitiators include benzoin and benzoin ethers such as marketed under the tradenames ESACURE BO, EB1, EB3, and EB4 from Fratelli Lamberti; VICURE 10 and 30 from Stauffer; benzil ketals such as 2,2-dimethoxy-1,2-diphenylethan-1-one (IRGACURE 651), 2-hydroxy-2-methyl-1-phenylpropan-1-one (IRGACURE 1173), 2-methyl-2-morpholino-1-(p-methylthiophenyl)propan-1-one (IRGACURE 907), alpha-hydroxyalkylphenones such as (1-hydroxycyclohexyl)(phenyl)methanone (IRGACURE 184), 2-benzyl-2-(dimethylamino)-1-(4-morpholinophenyl)butan-1-one (IRGACURE 369), 2-hydroxy-2-methyl-1-phenylpropan-1-one IRGACURE 1173) from Ciba Geigy, Uvatone 8302 by Upjohn; alpha, alpha-dialkoxyacetophenone derivatives such as DEAP and UVATONE 8301 from Upjohn; DAROCUR 116, 1173, and 2959 by Merck; and mixtures of benzophenone and tertiary amines In pigmented coating compositions, the rate of cure can be improved by the addition of a variety of phosphine oxide photoinitiaters such as bis(2,4,6-trimethylbenzoyl)-phenyl-phosphine oxide (Irganox 819), Irgacure 819, 1700, and 1700 and phosphine oxide mixtures such as a 50/50 by weight mixtures of IRGACURE 1173 and 2,4,6-trimethylbenzoyldiphenylphosphine oxide (DAROCUR 4265) from Ciba. Further details regarding such photoinitiators and curing procedures may be found in the published literature such as U.S. Pat. No. 5,109,097, incorporated herein by reference. Depending upon the thickness of the coating (film), product formulation, photoinitiator type, radiation flux, and source of radiation, exposure times to ultraviolet radiation of about 0.5 second to about 30 minutes (50-5000 mJ/square cm) typically are required for curing. Curing also can occur from solar radiation, i.e., sunshine. 
     The coating compositions of the present invention may contain one or more additional components typically present in coating compositions. Examples of such additional components include leveling, rheology, and flow control agents such as silicones, fluorocarbons or cellulosics; flatting agents; pigment wetting and dispersing agents; surfactants; ultraviolet (UV) absorbers; UV light stabilizers; tinting pigments; defoaming and antifoaming agents; anti-settling, anti-sag and bodying agents; anti-skinning agents; anti-flooding and anti-floating agents; fungicides and mildewcides; corrosion inhibitors; thickening agents; and/or coalescing agents. The coating compositions of the present invention also may contain non-reactive modifying resins. Typical non-reactive modifying resins include homopolymers and copolymers of acrylic and methacrylic acid; homopolymers and copolymers of alkyl esters of acrylic and methacrylic acid such as methyl, ethyl, n-propyl, isopropyl, butyl, tetrahydrofurfuryl, cyclohexyl, isobomyl, n-hexyl, n-octyl, isooctyl, 2-ethylhexyl, lauryl, stearyl, and benzyl acrylate and methacrylate; acrylated and methacrylated urethane, epoxy, and polyester resins, silicone acrylates, cellulose esters such as cellulose acetate butyrates, cellulose acetate, propionates, nitrocellulose, cellulose ethers such as methyl cellulose, ethyl cellulose, hydroxypropyl cellulose, and hydroxypropyl methyl cellulose.

Specific examples of additional additives can be found in  Raw Materials Index,  published by the National Paint &amp; Coatings Association, 1500 Rhode Island Avenue, N.W., Washington, D.C. 20005. 
     The third embodiment of the present invention pertains to a polymeric composition, typically a polymeric coating, comprising a polymer of one or more acrylic acid esters, one or more methacrylic acid esters and/or other polymerizable vinyl compounds, having copolymerized therein one or more of the thermally-stable, colored, photopolymerizable compounds described herein. The colored polymeric compositions provided by our invention may be prepared from the coating compositions described above and typically contain from about 0.005 to 30.0 weight percent, preferably from about 05 to 15.0 weight percent, of the reactive or polymerized residue of one or more of the vinyl dye compounds described herein based on the weight of the composition or coating. The novel polymeric coatings may have a thickness of about 2.5 to 150 microns, more typically about 15 to 65 microns. 
     The polymeric coatings of the present invention typically have a solvent resistance of at least 100 MEK double rubs using ASTM Procedure D-3732; preferably a solvent resistance of at least about 200 double rubs. Such coatings also typically have a pencil hardness of greater than or equal to F using ASTM Procedure D-3363; preferably a pencil hardness of greater than or equal to H. The coating compositions can be applied to substrates with conventional coating equipment. The coated substrates are then exposed to radiation such as ultraviolet light in air or in nitrogen which gives a cured finish. Mercury vapor or Xenon lamps are applicable for the curing process. The coatings of the present invention can also be cured by electron beam. 
     The radiation-curable coating compositions of this invention are suitable as adhesives and coatings for such substrates as metals such as aluminum and steel, plastics, glass, wood, paper, and leather. On wood substrates the coating compositions may provide both overall transparent color and grain definition. Various aesthetically-appealing effects can be achieved thereby. Due to reduced grain raising and higher film thicknesses, the number of necessary sanding steps in producing a finished wood coating may be reduced when using the colored coating compositions of the invention rather than conventional stains. Coating compositions within the scope of our invention may be applied to automotive base coats where they can provide various aesthetically-appealing effects in combination with the base coats and color differences dependent on viewing angle (lower angles create longer path lengths and thus higher observed color intensities). This may provide similar styling effects as currently are achieved with metal flake orientation in base coats. 
     Various additional pigments, plasticizers, and stabilizers may be incorporated to obtain certain desired characteristics in the finished products. These are included in the scope of the invention. 
     Coating, Curing, and Testing Procedures: 
     Samples of formulations were used to coat glass plates using a knife blade. The wet film thickness was about 15 to 75 microns (0.6 to 3.0 mils). The solvent was evaporated to give a clear, somewhat tacky film. Prior to exposure to UV radiation, each film was readily soluble in organic solvents. 
     The dried film on the glass plate was exposed to UV radiation from a 200 watt per inch medium pressure mercury vapor lamp housed in an American Ultraviolet Company instrument using a belt speed of 25 ft. per minute. One to five passes under the lamp resulted in a crosslinked coating with maximum hardness and solvent resistance. 
     Each cured coating (film) may be evaluated for Konig Pendulum Hardness (ASTM D4366 DIN 1522), solvent resistance by the methyl ethyl ketone double-rub test, and solubility in acetone before and after exposure to UV radiation. The damping time for Konig Pendulum Hardness on uncoated glass is 250 seconds; coatings with hardness above 100 seconds are generally considered hard coatings. The methyl ethyl ketone (MEK) double rub test is carried out in accordance with ASTM Procedure D-3732 by saturating a piece of cheese cloth with methyl ethyl ketone, and with moderate pressure, rubbing the coating back and forth. The number of double rubs is counted until the coating is removed. The acetone solubility test is carried out by immersing a dry, pre-weighed sample of the cured film in acetone for 48 hours at 25° C. The film is removed, dried for 16 hours at 60° C. in a forced-air oven, and reweighed. The weight percent of the insoluble film remaining is calculated from the data. 
     COATING EXAMPLES 
     The coatings and coating compositions provided by the present invention and the preparation thereof are further illustrated by the following examples. 
     Example 129 
     A colored, photopolymerizable composition was prepared by thoroughly mixing 22.9 g of dipropylene glycol diacrylate, 69.1 g of Jaegalux UV-1500 (acrylated polyester oligomers), the blue compound of Example 6b (4 g of a 1.25% solution of the colored compound in dipropylene glycol diacrylate), and 4 g of Darocure1173 photoinitiator in a small Cowles mixer until the components were completely dispersed. This coating composition was drawn down with a wire wound rod to provide a 25.4 micron (1 mil) thick coating on an Oak wood panel. This panel was passed through a UV cure machine at a speed of 6.1 meters per minute (20 feet/minute) using a lamp with an intensity of 118.1 watts per cm (300 watts per inch). Hardness measurements were conducted on glass using a Konig pendulum and did not indicate any significant loss of hardness due to incorporation of the dye; hardness was 83 Konig seconds. Adhesion of the coating to an oak wood panel was measured using the crosshatch adhesion method according to ASTM method D 3359 (ISO 2409). A right angle lattice pattern (6 lines in each direction) is cut into the coating, penetrating to the substrate, creating 25 squares with each side of the squares measuring 1 mm. A 2.5 cm (1 inch) wide piece of tape is applied to the lattice, pressure is applied, and then the tape is pulled from the substrate. If the edges are smooth and none of the squares are detached, the adhesion is 100% (ASTM rating 5B). On the wood panel a 5B rating was achieved for both the reference and the dye-containing coatings. All the coatings withstood more than 300 MEK double rubs. No loss of solvent resistance was observed with incorporation of the dye. 
     Example 130 
     A colored, photopolymerizable composition was prepared by thoroughly mixing 10.0 g dipropylene glycol diacrylate, 10.0 g tripropylene gylcol triacrylate, 20.0 g Jaegalux UV-1500 (acrylated polyester oligomers), 15 g Jaegalux UV-3800 (acrylated epoxy oligomers), the blue compound of Example 6b (5.5 g of a 1.25% solution of the dye in dipropylene glycol diacrylate), and 2.2 gram of Irgacure 819 photoinitiator in a small Cowles mixer until the components were completely dispersed (20 minutes at 12,000 revolutions per minute). This coating composition was drawn down with a wire wound rod to provide a 38.1 micron (1.5 mil) thick coating on a cold rolled steel panel (iron phosphate pretreatment) and on polyethylene terephthalate sheet. The coated steel panel and polyester sheet were passed through a UV cure machine at a speed of 6.1 meters per minute (20 feet/minute) using a lamp with an intensity of 118.1 watts per cm (300 watts per inch). The Konig pendulum hardness of the coatings on the steel panels was 126 Konig seconds. No significant loss of hardness (relative to the reference coating) due to incorporation of the dye was observed. All the coatings withstood more than 500 MEK double rubs. No significant loss of solvent resistance was observed with incorporation of the dye. Adhesion tests of the coatings on polyethylene terephthalate sheeting using the crosshatch adhesion method described in Example 129 showed no loss of adhesion due to incorporation of the dye and 100% adhesion for the coatings. 
     Example 131 
     A colored, photopolymerizable composition was prepared by thoroughly mixing the blue compound of Example 6b (10 g of a 2% solution of the dye in dipropylene glycol diacrylate), 20 gram trimethylol propane triacrylate, 20 g of polyester acrylate oligomer, 15 g of bisphenol A epoxy acrylate, and 4 gram of PI 1173 photoinitiator in a small Cowles mixer until the components were completely dispersed. The resulting coating composition was drawn down with a wire wound rod to provide a 25.4 micron (1 mil) thick coating on a 20 gauge sheet (1.27 mm—50 mils—thick) of polyethylene terephthalate (PET). The coated sheet was passed through a UV cure machine at a speed of 6.1 meters per minute (20 feet/minute) using a lamp with an intensity of 118.1 watts per cm (300 watts per inch). Hardness measured on glass by the Konig Pendulum method indicated no reduction of the hardness due to the dye; hardness was 105 Konig seconds. Adhesion tests of the coatings on polyethylene terephthalate sheet in accordance with the crosshatch adhesion method described in Example 129 showed no loss of adhesion due to incorporation of the dye and 100% adhesion for the coatings. All the coatings withstood more than 300 MEK double rubs. No significant loss of solvent resistance was observed with incorporation of the dye. The coating provided an attractive even color over the entire coated sheet. 
     The invention has been described in detail with particular reference to preferred embodiments thereof, but it will be understood that variations and modifications can be effected within the spirit and scope of the invention.
