A polyurethane resin obtained from a diisocyanate compound and a polyester polyol. The polyester polyol may (1) comprise not less than 50% by weight of a polyester glycol having a molecular weight of 500-5,000, the polyester glycol being obtained by reacting an acid and 3,3,5-trimethyl-1,6-hexanediol or 2,2,4-trimethyl-1,6-hexanediol and have a molecular weight of 500-5,000, (2) have a number average molecular weight of 500-5,000 and an alcohol hydroxyl group at terminals thereof and comprise not less than 50% by weight of ester units, the ester units being derived from a dicarboxylic acid and 3,3,5-trimethyl-1,6-hexanediol and/or 2,2,4-trimethyl-1,6-hexanediol, or (3) have a number-average molecular weight of 500-5,000 and comprise not less than 50% by weight of ester units of an aliphatic dicarboxylic acid and trimethyl-1,6-hexanediols. The above polyurethane resins may be combined with chlorinated polyolefin and then used in binder compositions or, alternately used in coating compositions for decoration paper made of a polyolefin resin. The above polyurethane resins may also be laminated on at least one surface of a woven cloth made of synthetic resin to form a laminated clothing that may further be used in an air bag for a vehicle.
A binder composition obtained from a chlorinated polyolefin and a polyurethane resin, said polyurethane resin being obtained by reacting a diisocyanate compound and a high molecular weight polyester polyol, said high molecular weight polyester polyol comprising not less than 50% by weight of a polyester glycol having a molecular weight of 500-5,000, said polyester glycol being obtained by reacting an acid and 3,3,5-trimethyl-1,6-hexanediol or 2,2,4-trimethyl-1,6-hexanediol.
A coating composition for a decoration paper made of a polyolefin resin, the coating composition comprising a chlorinated polyolefin and a polyurethane resin, said polyurethane resin being obtained by reacting a diisocyanate compound and a high molecular weight polyester polyol having a number average molecular weight of 500-5,000, said polyester polyol having an alcohol hydroxyl group at terminals thereof and comprising not less than 50% by weight of ester units, said ester units being derived from a dicarboxylic acid and 3,3,5-trimethyl-1,6-hexanediol and/or 2,2,4-trimethyl-1,6-hexanediol.
A laminated cloth obtained by laminating a polyurethane resin on, at least, one surface of a woven cloth made of synthetic resins, said polyurethane resin being obtained from a diisocyanate compound and a polyester polyol having a number-average molecular weight of 500-5,000 and comprising not less than 50% by weight of ester units of an aliphatic dicarboxylic acid and trimethyl-1,6-hexanediols.
