DEVELOPER INK COMPOSITION FOR INKJET, AND PRESSURE-SENSITIVE RECORDING BODY USING THE INK COMPOSITION

摘要

PROBLEM TO BE SOLVED: To provide a development sheet for pressure-sensitive recording having satisfactory initial coloring, a pressure-sensitive recording body having the development sheet for pressure-sensitive recording, and a developer ink composition for inkjet for easily producing the development sheet for pressure-sensitive copying.

SOLUTION: The developer ink composition for inkjet is composed of an aqueous dispersion including: a developer made of the polyvalent metal salt (A) of salicylic acid or its derivative; an alkali-soluble stylene-acrylic resin (B); and a basic substance (C). The area-average particle diameter of the polyvalent metal salt (A) of salicylic acid or its derivative is 10 to 500 nm, the acid value of the alkali-soluble stylene-acrylic resin (B) is 5 to 120 mgKOH/g, and also, the pH of the ink composition is 4 to 9.
