MANUFACTURING METHOD OF MICROCAPSULE, MICROCAPSULE MANUFACTURED BY THE MANUFACTURING METHOD, RECORDING PAPER ON WHICH INFORMATION IS RECORDED BY USING MICROCAPSULE, AND RECORDING LIQUID CONTAINING MICROCAPSULE

摘要

PROBLEM TO BE SOLVED: To prepare a microcapsule having self-color development characteristics.

SOLUTION: In the manufacturing method of the microcapsule, a water-soluble color developing agent as a core material and a water-soluble polymer aqueous solution of concentration of 15 wt.% to 30 wt.% are dispersed into organic solvent and are subjected to interfacial polymerization with a reaction agent to form a microcapsule wall film, and a hygroscopic coated film is formed on the microcapsule wall film by using hygroscopic liquid.
