PURPOSE:To realize high recording density and good intermediate tone by removing close adhesive property to a dyeing layer of a color material layer of a color sheet, by providing a cushion layer between a base material and the dyeing layer. CONSTITUTION:A cushion layer 2 is provided on a base material 1, and a dyeing layer 3 is provided thereon. As a construction of the cushion layer 2, there are (1) a structure in which at least a surface of the base material 1 is made foamy, (2) a structure in which after coating a mixture of resin of good film- forming property such as vinyl chloride and vinyl acetate copolymer, vinyl acetate, urethane resin, etc., and foaming agent such as ammonium carbonate, sodium bicarbonate, azodicarbonamide, azobisisobutyronitrile, benzenesulfonyl hydrazide, etc. on the base material 1, this coated layer is foamed, (3) a structure in which materials having rubber elasticity are coated on, at least, one side surface of the base material, etc. |
