PURPOSE:To obtain a thermally transferred records with sharp cyan color by using azomethine color of specific pyrazoquinazoline type. CONSTITUTION:Azomethine of pyrazoquinazoline type as shown by the formula is used. In the formula, R1 is a substituted or non-substituted alkyl group, cycloalkyl group, aralkyl group or aryl group, and R2 is a substituted or non- substituted alkyl group, cycloalkyl group, aralkyl group or aryl group. In addition, R1 and R2 can from a 5-member ring or a 6-member ring which can contain an oxygen atom, a nitrogen atom or a sulfur atom. R3, R3, R4 are a hydrogen atom, a halogen atom, a cyano group, an alkyl group, an alkoxy group, an aryl group, an aralkyl group, an acylamino group, a ureido group, an acyl group or an amino group. X is a hydrogen atom, or atomic group or in an atom which forms a 5-member ring or a 6-member ring with R1, and m and n are 1 or 2. |
