PURPOSE: To improve visibility, image stability, and color density of printed objects by providing a bearing material with a dye receptor element layer made from polyurethane, in which polymer containing hydroxyl group bridging over polyisocyanate. CONSTITUTION: From groups of polymers containing polyether, polyester, polymerized acrylate monomer, and polymers containing monomer selected from vinyl acetate, vinyl butyral, maleic acid, polymers are selected and bridged over polyisocyanate to synthesis polyurethane containing urethane group of 4% by weight. The polyurethane is dissolved in a solvent of methylethylketene, etc., to produce dye receptor layer fluid. The dye receptor layer fluid is applied on a bearing material of polyethyleneterephthalate film, etc., dried to make a dye receptor layer as a dye receptor element. An elastic layer, dye barrier layer, binder layer, etc., can be placed between the bearing material and the dye receptor layer as required. |
