Document Type and Number:
Japanese Patent JP6852361
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an aqueous composite resin dispersion exhibiting excellent base material adhesion, wet friction resistance and scratch resistance to a non-polar film base material under low temperature drying, and an aqueous ink composition containing the same.SOLUTION: An aqueous composite resin dispersion is formed by polymerization of an ethylenically unsaturated monomer (B) in an aqueous medium using an acrylic/urethane composite resin (A) as a polymer emulsifier, where the acrylic/urethane composite resin (A) is formed by polymerization of an ethylenically unsaturated monomer (G) containing using an urethane urea resin (E-2) containing mercapto groups at both terminals formed by reaction of an urethane prepolymer (E-1) obtained by polyol (C) and polyisocyanate (D) with a compound (F) represented by general formula (1) as a chain transfer agent.SELECTED DRAWING: None
