Title:
MOISTURE-CURABLE POLYURETHANE RESIN COMPOSITION, ADHESIVE, AND LAMINATE
Document Type and Number:
WIPO Patent Application WO/2021/054128
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing a moisture-curable polyurethane resin composition that exhibits an excellent adherence to fabrics (particularly water-repellent fabrics). The present invention provides a moisture-curable polyurethane hot-melt resin composition that is characterized by comprising an isocyanato group-bearing urethane prepolymer (i) that is a reaction product of a polyisocyanate (B) and a polyol (A) that contains a polyester polyol (a1) that is the reaction product of adipic acid-containing polybasic acid and a compound (x) that has a number-average molecular weight less than 500, has a branched structure, and has 2-4 hydroxy groups. The compound (x) is preferably one or more selected from the group consisting of 2-methyl-1,3-propanediol, 3-methyl-1,5-pentanediol, and neopentyl glycol.
