ABSTRACT:
A polyurethane resin composition having better heat resistance comprises one polyurethane resin; and polyethylene terephthalate resin and/or a polyamide resin, such as nylon 6 resin or nylon 66 resin, in an amount of 8 to 30 parts by weight per 100 parts by weight of the polyurethane resin. The polyurethane resin composition is made by mixing polyethylene terephthalate resin solution with O-chlorophenol as solvent, and/or nylon 6 or nylon 66 resin solution with formic or acetic acid as solvent, with the polyurethane resin solution; and then drying in oven to eliminate the solvent for making the skin of leather-like coated fabrics which is capable of heat transfer printing.
