SELF-CROSSLINKING POLYSILOXANE-MODIFIED POLYHYDROXY POLYURETHANE RESIN, RESIN MATERIAL CONTAINING SAME, METHOD FOR PRODUCING SAME, ARTIFICIAL LEATHER COMPRISING SAME, AND THERMOPLASTIC POLYOLEFIN SKIN MATERIAL COMPRISING SAME

摘要

Provided are a self-crosslinking polysiloxane-modified polyhydroxy polyurethane resin derived from a reaction of a 5-membered cyclic carbonate polysiloxane compound represented by the following formula (1) and an amine compound and having polysiloxane segments and masked isocyanate groups in its structure:
wherein A means
and its production process. The present invention can provide a polyhydroxy polyurethane resin, the development of applications of which has not moved ahead in the prior art, as a novel self-crosslinking polyhydroxy polyurethane resin that enables to provide products excellent in lubricity, abrasion resistance, chemical resistance, non-tackiness, heat resistance and the like, is useful from the viewpoint of the reduction of warming gas, and is responsive to the environment.
