A dry release sublimation transfer for decorating textile substrates is disclosed, including a temporary backing sheet, a sublimation transfer design layer comprising sublimation transfer inks disposed on the design layer, and a polymeric layer disposed in contact with the sublimation transfer design layer. The polymeric layer comprises a polymer having a number average molecular weight between about 700 and 20,000, and having on the average at least three functional groups comprising isocyanates for each polymer chain thereof, whereby upon application of the sublimation transfer under heat and pressure to the textile substrate which is to be decorated, the polymeric coating softens and penetrates into the textile substrate, along with the sublimation transfer design layer. In a preferred embodiment, the functional groups are blocked, so that upon application of the sublimation transfer under heat and pressure the functional groups on the polymer chain unblock or become reactive, and cross-linking occurs. In one embodiment, the polymer layer comprises an isocyanate functional polyurethane, blocked with phenol. In addition, a method for decorating textile substrates is also disclosed, employing the above-described dry release sublimation transfers.

A sublimation transfer for decorating a textile substrate comprising a temporary backing sheet, said backing sheet having deposited thereon a sublimation transfer design layer comprising a sublimation transfer ink having a sublimation point between about 100°and 300°C. and a polymeric layer disposed in contact with said design layer, said polymeric layer having a thickness of between about 0.4 and 4 mils and comprising a polymer having a number average molecular weight of between about 700 and 20,000, and having at least 3 functional groups comprising isocyanates for each polymer chain thereof, whereby upon application of said sublimation transfer to said textile substrate under heat and pressure, said polymeric coating is adapted to soften and penetrate into said textile substrate, and said polymer cross-links, at least a portion of said cross-linking being between said polymer and said textile substrate or moisture associated with said textile substrate. A sublimation transfer for decorating a textile substrate comprising a temporary backing sheet, said backing sheet having deposited thereon a sublimation transfer design layer comprising a sublimation transfer ink having a sublimation point between about 100°and 300°C., and a polymeric layer disposed in contact with said design layer, said polymeric layer having a thickness between about 0.4 and 4 mils and a number average molecular weight of between about 1,200 and 15,000, and having at least 3 functional groups comprising isocyanates for each polymer chain thereof, said polymer comprising a blocked isocyanate functional polyurethane, whereby upon the application of said sublimation transfer to said textile substrate under heat and pressure, said polymeric coating is adapted to soften and penetrate into said textile substrate, and said blocked isocyanate groups unblock or become reactive, so that said polymer cross-links, at least a portion of said cross-linking being between said polymer and said textile substrate or moisture associated with said textile substrate. A method for decorating a textile substrate with a design comprising one or more sublimation inks, which method comprises 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 comprising a sublimation transfer ink having a sublimation point between about 100°and 300°C., and a polymeric layer disposed in contact with said design layer, said polymeric layer having a thickness of between about 0.4 and 4 mils and comprising a polymer having a number average molecular weight of between about 700 and 20,000, and having on the average at least 3 blocked functional groups comprising isocyanates for each polymer chain thereof, whereby upon application of said sublimation transfer to said textile substrate, under heat and pressure including a temperature of between about 200°and 450°F. and a pressure of between about 2 and 100 psi said polymeric coating is adapted to soften and penetrate into said textile substrate, and said polymer cross-links, at least of portion of said cross-linking being between said polymer and said textile substrate or moisture associated with said textile substrate, positioning said dry release sublimation Transfer on a textile substrate to be decorated with said temporary backing sheet disposed away from said textile substrate, applying heat and pressure to said dry release sublimation transfer, thereby causing said polymeric layer to soften and penetrate into said substrate, while releasing said temporary backing sheet from said design layer, thereby cross-linking said isocyanate functional groups with said textile or said moisture associated with said textile and cooling said design layer and polymeric coating whereby said polymeric coating is securely embedded in said textile substrate.
