THERMAL TRANSFER IMAGE RECEIVING SHEET AND INK COMPOSITION FOR PRINTING DETECTION MARK ON BACK OF IMAGE RECEIVING SHEET

摘要

PROBLEM TO BE SOLVED: To provide an ink composition for printing a detection mark which is free from a printing defect of a detection mark arranged on the back even in the transfer of a releasing agent of a dye receiving layer to the back of the thermal transfer image receiving sheet, and to provide the thermal transfer image receiving sheet with a detection mark by using the ink composition.

SOLUTION: The printing defect of detection mark arranged on the back of sheet is prevented even in transfer of the releasing agent of the dye receiving layer to the back of the image receiving sheet in keeping the thermal transfer image receiving sheet roll, by forming the detection mark 4 on the back of a substrate sheet using the ink composition for printing detection mark on the back which comprises at least a binder of a thermoplastic resin, a coloring agent and silicone oil, with the proviso that 0.1-1.0 mass% of the silicone oil is contained to the solid component of the ink composition and the thermal transfer image receiving sheet 1 is arranged to have the dye receiving layer 3 at least containing a thermoplastic resin and a releasing gent on the front side of the substrate sheet 2.
