Claims
- 1. A method of forming a heat sensitive recording material composed of a colorant layer comprising a binder and a colorant peelably adhered to an image receiving layer, wherein a peeling force necessary to peel said colorant layer from said image receiving layer is 0.1 to 1000 g/mm at an angle of 180.degree., and with which an image is formed by applying heat to a surface of said colorant layer in a pattern corresponding to an image being formed whereby heated portions of said colorant layer are non-peelably adhered to said image receiving layer, a non-heated portion of said colorant layer being peeled from said image receiving layer, said method comprising;
- preparing a coating solution comprising said binder and said colorant, coating said coating solution onto said image receiving layer, and drying the coated solution to form said colorant layer, wherein said colorant comprises at least one material selected from the group consisting of organic pigments, inorganic pigments and dyes and said binder comprises at least one heat-fusible substance selected from the group consisting of vegetable wax, animal wax, petroleum wax, mineral wax, higher aliphatic acids, higher alcohols, higher aliphatic esters, and higher amines, at least one thermoplastic resin selected from the group consisting of polyacetals, polyamides, polyesters, polyurethanes, polyacrylates, polyvinyl chloride, cellulose, rosin, ionomers, natural rubber, styrene-butadiene rubber, isoprene rubber, chloroprene rubber, ester gum, rosin-maleic resin, rosin-phenol resin, hydrogenated rosin, phenol resin, terpene resin, cyclopentadiene resin, and mixtures thereof.
- 2. The method of claim 1, wherein the thickness of said support is 1 to 500 .mu.m.
- 3. The method of claim 1, wherein a sublayer containing an adhesive is provided between said image receiving layer and said colorant layer.
- 4. The method of claim 3, wherein the thickness of said sublayer is 0.1 to 30 .mu.m.
- 5. The method of claim 1, wherein the colorant content of said thermosoftening colorant layer is within the range of 5 to 60% by weight.
- 6. The method of claim 1, wherein the thickness of thermosoftening colorant layer is within the range of 0.5 to 20 .mu.m.
- 7. The method of claim 1, wherein an antisticking layer is provided on a surface of the thermosoftening colorant layer furthest from said image receiving layer.
- 8. The method of claim 7, wherein the antisticking layer contains silicone resins.
- 9. The method of claim 8, wherein the silicone resin content of the antisticking layer is within the range of 1 to 100% by weight.
- 10. The method of claim 7, wherein the thickness of the antisticking layer is 0.03 to 30 .mu.m.
- 11. The method of claim 1, wherein said image receiving layer is a mordant layer and said colorant layer is a dye-supplying layer.
- 12. The method of claim 11, wherein said colorant layer contains a thermally diffusing dye.
- 13. The method of claim 12, wherein said dye has a molecular weight of from 50 to 4000.
- 14. The method of claim 1, wherein melting point, sublimation temperature or vaporizing temperature of said dye is within the range of 60.degree. to 300.degree. C.
- 15. The method of claim 1, wherein the dye content of said colorant layer is within the range of 5 to 80% by weight.
- 16. The method of claim 1, wherein the thickness of the dye-supplying layer is 0.5 to 30 .mu.m.
- 17. The method of claim 1, wherein said image receiving layer contains a sticking agent.
- 18. The method of claim 1, wherein said colorant layer contains a sticking agent.
- 19. The method of claim 1, wherein a sticking layer containing a sticking agent is provided between said image receiving layer and said colorant layer.
- 20. The method of claim 19, wherein said sticking agent is at least one material selected from the group consisting of natural rubber, chloroprene rubber, butyl rubber and polyacrylates.
- 21. The method of claim 1, wherein a transparent layer is provided on surface of the image receiving layer furthest from said colorant layer.
- 22. The method of claim 1, wherein a peelable layer containing at least one material selected from the group consisting of silicone resin, wax and a surfactant is provided between said image receiving layer and said colorant layer.
- 23. The method of claim 22, wherein the thickness of said peelable layer is 0.1 to 10 .mu.m.
- 24. The method of claim 1, wherein an anti-fogging layer containing at least one material selected from the group consisting of a thermoplastic resin, and a filler is provided between said image receiving layer and said colorant layer.
- 25. The method of claim 24, wherein the thickness of said anti-fogging layer is 0.3 to 10 .mu.m.
- 26. The method of claim 1, an image receiving layer and a colorant layer has a peelable layer provided on a surface of the colorant layer furthest from said image receiving layer.
- 27. The method of claim 26, wherein the material has an interlayer is provided between the image receiving layer and the colorant layer.
- 28. The method of claim 26, wherein said peelable support layer is composed of at least one material selected from polyacrylate resins, cellulose resins, polycarbonate resins, and polyparabanic acid resin.
- 29. The method of claim 1 wherein said thermoplastic resin is a diene copolymer.
- 30. The method of claim 1 wherein said thermoplastic resin is a polyolefin.
- 31. The method of claim 1 wherein said binder comprises a thermoplastic resin.
- 32. The method of claim 31 wherein said thermoplastic resin has a softening point of 50.degree. to 200.degree. C.
- 33. The method of claim 1 wherein an antifogging layer containing at least one material selected from the group consisting of a heat-fusible substance and a filler is provided between said image receiving layer and said colorant layer.
