Title:
WATER-COMPATIBLE REACTIVE RESIN AND PROCESS FOR PRODUCING THE SAME
Document Type and Number:
WIPO Patent Application WO/2008/018589
Kind Code:
A1
Abstract:
A water-compatible reactive resin giving a film which is equal in gloss, transparency, solvent resistance, and adhesion to films obtained from conventional water-compatible acrylic resins but is improved in water resistance, especially resistance to blushing with water; and a process for producing the resin. The water-compatible reactive resin is obtained by polymerizing (B) one or more polymerizable unsaturated monomers in the presence of (A) a water-compatible urethane resin having (a1) a reactive silyl group capable of forming a crosslinked structure and (a2) an anionic group. The urethane resin (A) preferably contains the reactive silyl group (a1) in an amount of 0.1-10 wt.% in terms of silicon amount and contains the anionic group (a2) in an amount of 0.01-1.1 meq/g. The monomers (B) preferably comprise an alkyl (meth)acrylate and a polymerizable silane monomer (C). The water-compatible reactive resin can form a film having a change in the value of resistance to blushing with water (ΔL) of 10 or lower.
