Abstract
Official abstract text for this publication.
SOLUTION There is provided a transfer sheet comprising a substrate, as well as a releasing layer and a hot melt colored layer in this order on the substrate, the hot melt colored layer comprising, as a binder resin, a (meth)acrylic resin having a glass transition temperature of not less than 75° C., and a colorant.
First claim
Opening claim text (preview).
The invention claimed is: 1. A transfer sheet comprising a substrate, and a releasing layer and a hot melt colored layer in this order on the substrate: the hot melt colored layer comprising, as a binder resin, a (meth)acrylic resin having a glass transition temperature of not less than 75° C., and a colorant, wherein the releasing layer comprises a vinyl chloride-vinyl acetate resin, and wherein the content of the vinyl chloride-vinyl acetate resin in the releasing layer is not less than 80% by mass. 2. The transfer sheet according to claim 1 , wherein the content of the (meth)acrylic resin in a binder resin of the hot melt colored layer is not less than 50% by mass. 3. The transfer sheet according to claim 2 , wherein the weight average molecular weight of the (meth)acrylic resin is 20000 or more and 100000 or less. 4. The transfer sheet according to claim 2 , further comprising a mold release layer between the substrate and the releasing layer. 5. The transfer sheet according to claim 2 , further comprising a dye layer on the substrate. 6. The transfer sheet according to claim 1 , wherein the weight average molecular weight of the (meth)acrylic resin is 20000 or more and 100000 or less. 7. The transfer sheet according to claim 6 , further comprising a mold release layer between the substrate and the releasing layer. 8. The transfer sheet according to claim 6 , further comprising a dye layer on the substrate. 9. The transfer sheet according to claim 1 , further comprising a mold release layer between the substrate and the releasing layer. 10. The transfer sheet according to claim 9 , further comprising a dye layer on the substrate. 11. The transfer sheet according to claim 1 , further comprising a dye layer on the substrate.
