PURPOSE: To obtain a magenta thermosensible transfer sheet having good gradation, high color density, and a good preservative property by mounting an ink layer containing a benzothiazol azo compound expressed by a specified formula on a support. CONSTITUTION: A clear magenta coloring matter which is used in the ink layer of a thermosensible transfer sheet is prepared from a benzothiazol azo compound expressed by a formula. An ink layer containing the magenta coloring matter is mounted on a support to form a required thermosensible transfer sheet. In the formula, X1 -X4 is hydrogen atom, halogen atom, substituted or unsubstituted alkyl group, nitro group, cyano group, substituted or unsubstituted alkoxy group, etc., Y is hydrogen atom, halogen atom, substituted or unsubstituted alkyl group, substituted or unsubstituted alkoxy group, R1 , R2 are independently hydrogen atom, substituted or unsubstituted alkyl group, allyl group, and substituted or unsubstituted aryl group. |
