Document Type and Number:
WIPO Patent Application WO/2023/097571
Kind Code:
A1
Abstract:
An object of the present invention is to provide a moisture-curable polyurethane hot-melt resin composition having excellent adhesion to fabrics (in particular, water-repellent fabrics) and excellent laundering resistance. The present invention provides a moisture-curable polyurethane hot-melt resin composition including an isocyanate-group-containing urethane prepolymer (i). The isocyanate-group-containing urethane prepolymer (i) is a reaction product of a polyol (A) and a polyisocyanate (B). The polyol (A) includes a compound (a1) represented by general formula (1) below. Preferably, an amount of use of the compound (a1) in the polyol (A) is within a range of 0.5 to 30 mass % relative to a total mass of the polyol (A). Preferably, the polyol (A) further includes at least one of a polyester polyol or a polyether polyol.
