Hot-melt resin composition, its production in powder form and hot-melt resin powder composition

摘要

The present invention provides a hot-melt resin composition which comprises 1 to 30% by weight of a compound represented by the general formula (1) Q-(X-A)n (wherein X is a urethane or urea group, Q is a group with a valence of n, A is a univalent group, one of Q and A being an isocyanate residue and the other being an amine or alcohol residue, and n is an integer of 1 to 3) and 70 to 99% by weight of a thermoplastic polyurethane resin (B); a method of producing a powder form of said hot-melt resin composition; and a hot-melt resin powder composition which comprises said powder-form hot-melt resin composition.
