Title:
WATER-BASED RESIN COMPOSITION, WATER-BASED COATING MATERIAL, AND ARTICLE COATED WITH SAID WATER-BASED COATING MATERIAL
Document Type and Number:
WIPO Patent Application WO/2022/202172
Kind Code:
A1
Abstract:
Provided is a water-based resin composition which comprises a polypropylene-modified acrylic resin that is a reaction product of polypropylene (A) and an unsaturated monomer mixture (B) and a water-based medium, the water-based resin composition being characterized in that the polypropylene (A) is a homopolymer, the unsaturated monomer mixture (B) contains an unsaturated monomer (b1) having a carboxyl group, and the acid value of the polypropylene-modified acrylic resin is 20 to 80 mgKOH/g. The water-based resin composition has excellent storage stability, and can provide a coating film having excellent adhesion to various types of substrates, and therefore the water-based resin composition can be used suitably for various types of coating materials.
