  • Patent number: 5234983
    Abstract: A coating composition for a substrate to be imprinted with an image by means of sublimation or heat transfer that comprises a mixture of an epoxy resin and a blocked polyisocyanate in an equivalent-weight ratio in a range from 0.5 to 1.8 in appropriate solvents When cured, this composition results in a low glass-transition-temperature polyurethane that is smooth, colorless, tough, clear and glossy, capable of accepting a perfect reproduction of the transfer print. Upon exposure to hot water during dishwashing, the unreacted polymer-bound isocyanate groups further react to form a skin of highly crosslinked polymer chains. The skin creates a barrier to the deleterious effects of water on adhesion and to the diffusion of sublimation dyes out of the coating. The resulting transferred image is colorfast and the coating has strong adhesion to ceramic surfaces to survive repeated mechanical dishwashing.
