IPC: C09D101/08
Filed: 1937-06-19
Abstract: The surface of an article made of or coated with a composition comprising a simple or mixed halogen-containing vinyl polymer and a softening agent is coated with a layer of a cellulose ester or ether composition containing a mixed polymer of styrene with an ester, amide, or nitrile derivative of acrylic, methacrylic, or maleic acid. The presence of the mixed polymer in the cellulose derivative composition ensures a firm adhesion of the coating. Polyvinyl chloride, after-chlorinated polyvinyl chloride, mixed polymers from vinyl chloride or bromide with acrylic, methacrylic, or maleic esters, or mixed polymers with vinyl esters of fatty acids, may form the substance of the article or coating to which the cellulose derivative coating is applied.  The process may be used in the production of artificial leather, lining materials, blind materials, insulating sheets, or gramophone records.  The cellulose derivative may be an acetate, nitrate, acetobutyrate or other ester, or ethyl, benzyl or other ether.  In an example, a fabric is coated with a composition of polyvinyl chloride, tricresyl and triphenyl phosphate. Upon this coating there is applied a paste containing cellulose nitrate, a polymer of styrene and butyl acrylate, pigment, butyl acetate, toluene, xylene, ethyl acetate, and methoxy butylene glycol acetate.  A material of antique leather appearance is obtained.  In another example, a film of polyvinyl chloride and dibutyl phthalate is united to a textile or paper web, and a paste comprising cellulose nitrate, castor oil, softener, mixed polymer of styrene and methyl acrylate, and pigment, is then applied.  In another example, a gramophone record blank is made from a composition of polyvinyl chloride or a mixed polymer of vinyl chloride and methyl acrylate, and a benzoic ester of a fatty alcohol of 10-17 C atoms.  Upon this base layer there is brushed or sprayed a dilute solution of a mixed polymer from styrene and butyl acrylate and after superficial drying there is applied a solution of benzyl cellulose, dibutyl phthalate, a small amount of the mixed polymer, and a solvent mixture.  In another example, a record blank is obtained by spraying a sheet of polyvinyl chloride with a solution in toluene, ethyl acetate, and methylene chloride of a mixed polymer of styrene and butyl acrylate, applying a layer of cellulose nitrate containing a proportion of the mixed polymer, and finally applying a coating of cellulose nitrate, di-butyl phthalate, tricresyl phosphate, and butyl oleate.ALSO:The surface of an article made of or coated with a composition comprising a softening agent and a simple or mixed halogen-containing vinyl polymer is coated with a layer of a cellulose ester or ether composition containing a mixed polymerizate of styrene with a derivative, i.e. an ester, amide or nitrile, of acrylic, methacrylic, or maleic acid.  The presence of the mixed polymer in the cellulose derivative composition secures firm adhesion of the coating. Polyvinyl chloride, after-chlorinated polyvinyl chloride, mixed polymers from vinyl chloride or bromide with esters of acrylic, methacrylic or maleic acid, or mixed polymers with vinyl esters of fatty acids, may form the substance of the article or coating to which the cellulose derivative composition is applied.  The process may be used in the production of artificial leather, leather- or wax-cloth, lining materials, blind or shade materials, insulating sheets, or gramophone records.  The cellulose derivative may be cellulose nitrate, acetate, acetobutyrate or other ester, or ethyl, benzyl, or other ether.  In an example, a textile fabric is coated with a composition of polyvinyl chloride containing tricresyl and triphenyl phosphate.  Upon this coating there is applied a paste comprising high viscosity cellulose nitrate, a polymerizate from styrene and butyl acrylate, pigment, butyl acetate, toluene, xylene, ethyl acetate, and methoxy butylene glycol acetate.  A material having the appearance of antique leather is thus produced.  In another example, a film of polyvinyl chloride containing dibutyl phthalate is united by heat and pressure to a textile or paper web, and there is then applied a paste comprising cellulose nitrate, castor oil, softener, mixed polymerizate from styrene and methyl acrylate, and pigment.  In another example, a gramophone record blank is made from a composition comprising polyvinyl chloride or a mixed polymerizate from vinyl chloride and methyl acrylate, and a benzoic ester of a fatty alcohol containing 10-17 carbon atoms.  Upon this base layer there is brushed or sprayed a dilute solution of a mixed polymer from styrene and butyl acrylate, and after superficial drying there is applied a solution of benzyl cellulose, dibutyl phthalate, a small amount of the mixed polymer, and a solvent mixture.  In another example, a gramophone record blank is obtained by spraying a sheet of polyvinyl chloride with a solution in toluene, ethyl acetate, and methylene chloride, of a mixed polymer from styrene and butyl acrylate, applying a layer of cellulose nitrate containing a proportion of the mixed polymer, and finally applying a layer of cellulose nitrate composition containing dibutyl phthalate, tricresyl phosphate, and butyl oleate.
