Abstract
A dye receiving sheet includes a substrate and at least one dye receiving layer on one side of the substrate. The dye receiving layer includes: (a) polymers, wherein the polymers include PVC or PVC-VA copolymer or a mixture thereof, and the polymers are in an amount of 60-85 parts by weight based on the total weight of 100 parts by weight of the dye receiving layer; (b) a plasticizer, wherein the plasticizer has a melting point higher than 40° C., and the plasticizer is in an amount of 10-35 parts by weight based on the total weight of 100 parts by weight of the dye receiving layer; and (c) heat stabilizer, wherein the stabilizer is in an amount of 2-8 parts by weight based on the total weight of 100 parts by weight of the dye receiving layer.
