Title:
RESIN COMPOSITION AND SYNTHETIC LEATHER
Document Type and Number:
WIPO Patent Application WO/2019/202938
Kind Code:
A1
Abstract:
The present invention provides a resin composition containing a urethane resin (A), an acrylic resin (B), and water (C), the resin composition being characterized in that the acrylic resin (B) is a polymer of a polymerizable compound that contains a hydroxyl group-bearing (meth)acrylic compound (b-1), and the glass transition temperature of the composition is at least 40°C. The present invention also provides a synthetic leather having at least a base material (i), an adhesive layer (ii), and a skin layer (iii), the synthetic leather being characterized in that the skin layer (iii) is formed by the resin composition. The polymerizable compound that is a starting material for the acrylic resin (B) preferably contains, in addition to (b-1), a polymerizable compound (b-2) for which the hydrogen bonding component (δH) among the Hansen solubility parameters is at least 2.2 MPa0.5.
