Decorative plate

Abstract

A decorative glass or plastic plate comprising a primer layer of a light-permeable polyurethane resin, a transfer-printed layer of a printed image formed of an ink containing a pigment and a binder, and a cured resin layer, these layers being formed consecutively on one surface of a light-permeable glass plate.

What is claimed is: 
     
       1. A decorative glass plate comprising a primer layer of light-permeable polyurethane resin which is a room temperature-curing resin and has a thickness of .Iadd.1 to .Iaddend.100 μm a transfer-printing layer of a printed image formed of an ink containing a pigment and a binder, and a cured resin layer, these layers being formed consecutively on one surface of a light-permeable glass plate. 
     
     
       2. A decorative glass plate according to claim 1 wherein the polyurethane resin is a nonyellowing polyurethane resin. 
     
     
       3. A decorative glass plate according to claim 2 wherein the polyurethane resin comprises a polyisocyanate which is an aliphatic polyisocyanate or alicyclic polyisocyanate. 
     
     
       4. A decorative glass plate according to claim 1 wherein the transfer-printed layer is formed by bringing a printed surface of a transfer sheet on which a printing image is formed into thermal contact with the primer layer under pressure. 
     
     
       5. A decorative glass plate according to claim 4 wherein the printing image formed on the transfer sheet is formed of an ink containing a vinyl chloride-vinyl acetate copolymer. 
     
     
       6. A decorative glass plate according to claim 1 wherein the cured resin layer comprises a room temperature-curing resin. 
     
     
       7. A decorative glass plate according to claim 6 wherein the cured resin layer contains up to 60% by weight of a pigment. 
     
     
       8. A decorative glass plate according to claim 4 wherein the transfer sheet has an image formed by a gravure printing method. 
     
     
       9. A decorative plastic plate comprising a primer layer of a light-permeable polyurethane resin which has a thickness of 1 to 100 μm, a transfer-printed layer of a printed image formed of an ink containing a pigment and a binder, and a cured resin layer, these layers being formed consecutively one one surface of a light-permeable plastic plate. 
     
     
       10. A decorative plastic plate according to claim 9 wherein the light-permeable plastic plate is formed of at least one plastic selected from a group consisting of polymethyl methacrylate, polycarbonate, polyethylene terephthalate, nylon, epoxy and polymethyl pentene. 
     
     
       11. A decorative plastic plate according to claim 9 wherein the polyurethane resin is a nonyellowing polyurethane resin. 
     
     
       12. A decorative plastic plate according to claim 9 wherein the polyurethane resin comprises a polyisocyanate which is an aliphatic polyisocyanate or alicyclic polyisocyanate. 
     
     
       13. A decorative plastic plate according to claim 9 wherein the transfer-printed layer is formed by bringing a printed surface of a transfer sheet on which a printing image is formed into thermal contact with the primer layer under pressure. 
     
     
       14. A decorative plastic plate according to claim 13 wherein the printing image formed on the transfer sheet is formed of an ink containing a vinyl chloride-vinyl acetate copolymer. 
     
     
       15. A decorative plastic plate according to claim 9 wherein the cured resin layer comprises a room temperature-curing resin. 
     
     
       16. A decorative plastic plate according to claim 15 wherein the cured resin layer contains up to 60% by weight of a pigment. 
     
     
       17. A decorative plastic plate according to claim 9 wherein the transfer sheet has an image formed by a gravure printing method. 
     
     
       18. A decorative plastic plate according to claim 9 wherein the light-permeable plastic plate has a hard coat layer formed on one surface thereof, opposite to the surface of the plate on which the transfer-printed layer is formed. 
     
     
       19. A decorative plastic plate according to claim 18 wherein the hard coat layer is formed of a coating composition containing a thermosetting resin or a photo-setting resin.
