PROBLEM TO BE SOLVED: To provide the subject paper with the antioffset properties for preventing the transfer of a dye accepted on a dye acceptive layer to a back coat layer by providing the back coat layer with a polystyrene resin. SOLUTION: A synthetic paper is provided as a sheet-shaped base 2, on the surface of which a dye acceptive layer forming a coating material of the composition of a polyester resin of approximately 100 pts.wt., methyl ethyl ketone of approximately 100 pts.wt. and toluene of approximately 300 pts.wt. for forming the dry film thickness of approximately 10μm is applied and dried at approximately 120 deg.C for approximately two minutes. Then a back coat 4 forming a coating material of the composition of the polystyrene resin of approximately 100 pts.wt., polyisocyanate of approximately 50 pts.wt., conductive titanium oxide of approximately 100 pts.wt. and methyl ethyl ketone of approximately 400 pts.wt. is manufactured, and the coating material is applied on the face opposite to the face on the dye acceptive layer 3 of the sheet-shaped base 2 so that the dry film thickness is formed as approximately 1μm, and cured at approximately 50 deg.C for two days to manufacture a thermal transfer photographic paper 1. |
