<p>A method of heat treatment of a card-shaped recording medium, having at least a base member (101,201), an ink-receiving layer (102,202), and an ink-permeable outermost layer (103,203) formed on the base member to make the ink-permeable outermost layer impermeable to ink by means of a heating member (301) is conducted under the conditions that the temperature of the heating member (301) is higher than the glass transition temperature of the base member material (101,201), and the temperature at the half-depth position in the base member is not higher than the glass transition temperature thereof. <IMAGE></p> |
