DISPERSION FOR WATER-BASED INK

摘要

PROBLEM TO BE SOLVED: To provide a dispersion for a water-based ink having excellent fretting and maker resistance of prints and affording the water-based ink having excellent preservation stability and to provide a method for producing the dispersion for the water-based ink.

SOLUTION: The dispersion for the water-based ink comprises water-insoluble graft polymer particles containing (a) a constituent unit derived from a salt-forming group-containing monomer, (b) a constituent unit derived from a styrenic monomer and (c) a constituent unit derived from a styrenic macromer having a polymerizable functional group in one terminal in a dispersed state. The method for producing the dispersion for the water-based ink is provided.
