Method for preparing latex containing pigment copolymerized with a crystalline polymer

摘要

A method of preparing a latex that includes pigments copolymerized with a crystalline polymer includes: dispersing a pigment and a dispersing agent in water having an ultra-high purity to obtain a pigment dispersion; dissolving a crystalline monomer in a basic monomer mixture to obtain an organic phase; dissolving while heating the dispersing agent in water having an ultra-high purity, and then mixing the solution with the pigment dispersion to obtain an aqueous phase; mixing and agitating the organic phase and the aqueous phase to obtain a homogenized solution; agitating and heating the homogenized solution; adding a polymerization initiator to the homogenized solution to be reacted; and cooling the reaction solution to room temperature.
