Abstract

PURPOSE: To prepare the titled composition having excellent long-term color fastness to light or in air, exhibiting stable characteristics, and capable of changing its color successively over a wide temperature range, by using an electron-donative color-deloping pigment, a 1,2,3-triazole compound, and a high-boiling alcohol as the components.
CONSTITUTION: The objective composition is prepared by using (A) an electrondonative color-developing pigment[e.g. 4,4,6'-tris(dimethylamino)triphenylmethane.2'-lactone], (B) a 1,2,3-triazole compound (e.g. 1,2,3-benzotriazole) and (C) an alcohol (e.g. acetyl alcohol) or an amide (e.g. acetamide) having a boiling point of ≥150°C under atmospheric pressure in combination (pref. by encapsulation), as the components of the composition.
EFFECT: The composition can be prepared without using a delicate and complicate operation which is inevitable in the preparation of crylstal-containing ink composition, and it has no toxicity and excellent chelating and UV-absorbing capability.
