PURPOSE:To enhance a desensitizing effect to eliminate a setoff, by a method wherein a heat sensitive ink for pressure-sensitive paper is prepared by combining one or more selected from among two types of amine compounds shown by specific formulas in a specific ratio. CONSTITUTION:A desensitizer is prepared by blending at least one compound selected from among compounds shown by a formula I (R represents C12-C18 alkyl; and m + n represents integers 2-10, where m>=1, n>=1) or a formula II (R represents C12-C18 alkyl; R' represents C4-C8 alkyl; and m + n represents integers 2-8, where m>=1, n>=1) in a weight ratio ranging 97:3-50:50. The desensitizer is mixed with a resin, a pigment, and other additives which have been conventionally used for a desensitizing ink, thereafter being milled by a three-roll etc.; in this manner, a desensitizing ink is prepared. |
