AQUEOUS URETHANE RESIN COMPOSITION AND SYNTHETIC LEATHER
Document Type and Number:
WIPO Patent Application WO/2018/110105
Kind Code:
A1
Abstract:
The present invention provides an aqueous urethane resin composition containing: a urethane resin (A) which is a reactant of a polyol (a1), containing a polyol (a1-1) having an anionic group, and an aromatic polyisocyanate (a2), the concentration of the anionic group being 0.35 mmol/g or less; and an aqueous medium (B). In addition, the present invention provides a synthetic leather characterized in that at least a base fabric (i), an adhesive layer (ii), and a superficial layer (iii) are laminated, wherein the adhesive layer (ii) is formed of an aqueous urethane resin composition set forth in any one of claims 1-4. The purpose of the present invention is to provide an aqueous urethane resin composition which has excellent peeling strength, hydrolysis resistance, and light resistance.
