Title:
POLYCARBONATE-MODIFIED ACRYLIC RESIN, PAINT, AND PLASTIC MOLDED ARTICLE PAINTED BY SAID PAINT
Document Type and Number:
WIPO Patent Application WO/2020/044487
Kind Code:
A1
Abstract:
Provided is a polycarbonate-modified acrylic resin which is the reaction product of a polycarbonate diol (A) having 1,5-pentanediol and 1,6-hexanediol as raw materials and an unsaturated monomer mixture (B) containing as essential components methyl methacrylate, an unsaturated monomer (b1) having a hydroxyl group, an unsaturated monomer (b2) having a carboxyl group, and an unsaturated monomer (b3) having a C2-8 alkyl group, wherein the polycarbonate-modified acrylic resin is characterized in that the mass ratio of the unsaturated monomer (b2) in the unsaturated monomer mixture (B) is in the 2-10 mass% range. This polycarbonate-modified acrylic resin has high adhesiveness with plastic substrates and can be used suitably in a paint because a paint film having excellent water-resistant adhesiveness and aromatic resistance is obtained.
