(54) Porous ink acceptor sheet for thermal dye transfer printing


(57) Hot-melt type thermal ink transfer printing medium has an ink acceptance layer in which pores and microgrooves are contained, used for transferring hot-melt ink to the ink acceptance layer of the printing medium by using a thermal head. The printing medium satisfies at least one condition from a group of tow conditions that a 100 % stress of the ink acceptance layer in conformity with a measuring method of JIS-K-7127 is not less than 3,000 kN/m2 and a Young's modulus of the ink acceptance layer in conformity with a measuring method of JIS-K-7127 is not less than 8,000 kN/m2.
