(57) [Summary] [Object] To provide a film for hot melt bonding, which has good film forming property, low temperature flexibility, and good feeling, chemical resistance, dry cleaning property, heat resistance, and adhesive strength. Moreover, the manufacturing method and the manufacturing method of a thermoplastic polyurethane resin are provided. [Structure] At least one component of a composition comprising an aliphatic diisocyanate, a polymeric diol and a chain extender has one or more methyl group side chains in the molecule, which is obtained by a reaction without a solvent. Sa (JIS-A hardness) 65-9 It is a method for producing a thermoplastic polyurethane resin having a temperature of 0 ° C. and a flow starting temperature of 80 to 150 ° C. And it is a hot-melt film adhesive excellent in low-temperature flexibility obtained by hot-molding this thermoplastic polyurethane resin, and a method for producing the same. |
