PURPOSE:To make it possible to impart high color developability, a good head matching property and long-term storage stability, by using an ester compound of aromatic monocarboxylic acid or aromatic polyvalent carboxylic acid and aromatic alcohol in a part of a thermoplastic substance and specifying a basic substance. CONSTITUTION:An ester compound of aromatic monocarboxylic acid or aromatic polyvalent carboxylic acid and aromatic alcohol is used in a part of a thermoplastic substance and an imidazole deviative represented by formula (wherein R<3> is a higher alkyl group, an alkoxy group derived from a higher alkyl group or a hydroxyalkyl group and R<4>, R<5> and R<6> are hydrogen, a phenyl group, a benzyl group, an alkyl group, an alkoxy group, a hydroxyalkyl group or a cyanoalkyl group) is used in a part of a basic substance. As the imidazole derivative, 2-undecylimidazole is designated and used in an amount of 50wt% in combination with other thermoplastic substance. As the thermoplastic substance, an acid derivative, animal or vegetable waxes and others are used and the m.p. or softening point thereof is set to a range of 50-250 deg.C. By this method, high color developability, a good head matching property and excellent long-term storage stability are obtained. |
