A dry release sublimation transfer is provided which includes a temporary backing sheet having disposed thereon a sublimation transfer design layer formed of one or more sublimation transfer inks, and a polymeric coating disposed in contact with such design layer. In one embodiment, the design layer is first printed on the backing sheet employing conventional printing techniques and thereafter the polymeric coating is applied over the design layer. In another embodiment, the polymeric coating is first applied to the backing sheet and thereafter the design layer is printed over the polymeric coating. The dry release sublimation transfer is applied under heat and pressure to a substrate to be decorated, such as cotton fabric or a cotton-polyester fabric, thereby causing the polymeric coating to soften and penetrate into the substrate and upon cooling securely bond the design layer to the substrate. In addition, a method for decorating a substrate employing the above-described dry release sublimation transfer is provided.
A dry release sublimation transfer comprising a temporary backing sheet, said backing sheet having deposited thereon a sublimation transfer design layer comprised of one or more sublimation transfer inks having a sublimation point between about 100.degree. and 300.degree. C., and a discrete polymeric layer disposed in contact with said design layer, said polymeric layer comprising a polymer having a glass transition temperature within the range of from about -20.degree. C. to about 50.degree. C., a thickness of between about 0.1 and 20 mils, and having a softening point within the transfer range of said sublimation transfer inks, said polymer being selected from the group consisting of copolymers of butyl acrylate and methyl acrylate, acrylonitrilebutadiene-styrene terpolymers, copolymer of vinyl isobutyl ether and methyl methacrylate, copolymers of ethyl acrylate and methyl methacrylate, copolymers of ethyl acrylate and butyl methacrylate, copolymers of vinyl acetate and butyl acrylate, methyl acrylate polymers, copolymers of vinyl chloride and ethylene, copolymers of butyl acrylate and methyl methacrylate, copolymers of butyl acrylate and butyl methacrylate, copolymers of ethylene and vinyl acetate, copolymers of styrene and 1,3-butadiene, copolymers of vinyl isobutyl ether and methyl methacrylate, poly n-butyl methacrylate, poly n-propyl methacrylate, polyethyl methacrylate, polyvinyl chloride, polyacrylonitrile, polystyrene, polymethyl methacrylate, polyethyl acrylate, poly n-propyl acrylate and poly n-butyl acrylate whereby upon the application of said dry release sublimation transfer under heat and pressure to a cotton-containing textile substrate to be decorated, said polymeric layer is adapted to soften and penetrate into said substrate, and said design layer is transferred to said substrate, and upon cooling securely bonds said design layer to said textile substrate.
A method for decorating a textile substrate with a design comprising one or more sublimation inks having a sublimation point between about 100.degree. and 300.degree. C., which method includes the steps of providing a dry release sublimation transfer comprising a temporary backing sheet, said backing sheet having deposited thereon a sublimation transfer design layer comprised of one or more sublimation inks having a sublimation point between about 100.degree. and 300.degree. C., and a discrete polymeric layer disposed in contact with said design layer, said polymeric layer having a glass transition temperature within the range of from about -75.degree. C. to about 50.degree. C., a softening point within the transfer range of said sublimation inks, and a thickness of between about 0.1 and 20 mils, positioning said dry release sublimation transfer on a textile substrate to be decorated with said temporary backing sheet disposed away from said textile substrate, heating said dry release sublimation transfer to a temperature of from about 200 to about 450.degree. F., and a pressure of from about 2 to about 100 psig, thereby causing said design layer to be transferred to said textile substrate and said polymeric layer to soften and penetrate into said textile substrate, while releasing said temporary backing sheet from said design layer, and cooling said design layer and polymeric layer wherein said polymeric layer securely bonds said design layer to said textile substrate.
