Document Type and Number:
WIPO Patent Application WO/2020/230259
Kind Code:
A1
Abstract:
The present invention provides a urethane resin composition which contains a urethane resin (X) that uses, as essential starting materials, a polyol (A) containing a polycarbonate polyol (a1), a chain extender (B) other than the polyol (A) and a polyisocyanate (C), and which is characterized in that: the polyisocyanate (C) contains an aliphatic polyisocyanate (c1) and an aromatic polyisocyanate (c2); and the content of the aliphatic polyisocyanate (c1) is within the range of 1-45% by mass of the polyisocyanate (C). It is preferable that the aliphatic polyisocyanate (c1) is composed of one or more compounds selected from the group consisting of hexamethylene diisocyanate, isophorone diisocyanate, hydrogenated xylylene diisocyanate and pentamethylene diisocyanate.
