WATER-BASED RESIN COMPOSITION FOR GLASS BOTTLE COLORING, WATER-BASED COATING COMPOSITION, AND COLORED GLASS BOTTLE PRODUCED BY USING THE COMPOSITION

摘要

PROBLEM TO BE SOLVED: To provide a water-based resin composition for glass bottle coloring use capable of forming a colored coating film having excellent alkali resistance and hardness on the surface of glass and having long pot-life in spite of being a water-based coating material composed of an organic polymer. SOLUTION: The objective water-based resin composition for the coloring of glass bottle contains (A) a copolymer produced by the polymerization of (d) a hydroxyl-containingα,β-ethylenic unsaturated monomer, (e) a carboxyl- containingα,β-ethylenic unsaturated monomer and (f) otherα,β-ethylenic unsaturated monomer wherein a part or the total of the carboxyl group is neutralized with (h) a basic compound, (B) a compound having one or more carboxyl groups and two or more isocyanate groups blocked with a blocking agent having a dissociation temperature of 100-250 deg.C wherein a part or the total of the carboxyl group is neutralized with (h) the basic compound, (C) an epoxy compound and (D) water.
