Hydrophilic acryl-modified polyurethane and method for preparing the same, and waterborne coating composition prepared therefrom and method for preparing the same

摘要

The present invention relates to a hydrophilic acrylic-modified polyurethane and a method for producing the same, and a water-based coating composition using the same and a method for producing the same, and more particularly, to a polymer unit derived from an anhydrosugar alcohol-alkylene oxide adduct, polyisocyanate Hydrophilic property that can provide a water-based coating composition with improved eco-friendliness, adhesion (adhesion), crack resistance and water resistance, including a polymerization unit derived from and a polymerization unit derived from hydroxyalkyl (meth)acrylate It relates to an acrylic-modified polyurethane and a method for producing the same, and to a water-based paint composition using the same and a method for producing the same.
