Abstract
Thermal transfer recording media which make it possible to provide a highly sharpness and clear image even in case of printing on non-coated paper at a high speed and to improve the rub resistance of a printed area after the completion of printing. The present invention provides a thermal transfer recording medium comprising of a base material and a peel layer including a wax (A) and an ink layer including a styrene resin (B), a binder component (C) and a coloring component (D) laminated successively on the base material, wherein the wax (A) is compatible with the styrene resin (B). In the present invention, it is preferable that the weight ratio of the styrene resin (B) to the binder component (C) preferably ranges from 10:90 to 50:50.
Claims4
A thermal transfer recording medium, comprising:
- a base material in the form of a thin film;
- a peel layer laminated on said base material and including a candelilla wax (A);
- and,
- an ink layer laminated on said peel layer and including a styrene resin (B), a binder component including ethylene-vinyl acetate copolymer (C) and a coloring component (D), wherein said wax (A) is compatible with said styrene resin (B) when within a weight ratio range of 10:90 to 90:10 of the wax and the styrene resin, respectively, and at a temperature at least 30° C. more than the melting points of the wax (A) and the styrene resin (B), and the weight ratio of the styrene resin (B) to the binder component (C) ranges from 10:90 to 50:50.
