<P>PROBLEM TO BE SOLVED: To provide a slush molding material excellent in all of meltability, and heat resistance and mechanical properties of molded products. <P>SOLUTION: The urethane resin particle (D) includes a urethane resin or urethaneurea resin (U) covalently bonded with a residue (j) obtained by subtracting a hydroxy group from an aromatic tri- or more hydric polycarboxylic acid. It is preferable that the urethane or urea group (u) is hydrogen-bonded with the residue (j), and the (U) is a thermoplastic resin. A thermoplastic urethane resin particle composition (P) including the urethane resin particle (D) and at least one kind of additive (F) selected from the group of inorganic filler, pigment, plasticizer, release agent, antiblocking agent and stabilizer is preferably used. <P>COPYRIGHT: (C)2013,JPO&INPIT |
