<p><P>PROBLEM TO BE SOLVED: To provide a catalyst capable of producing a fine cell hard polyurethane foam having an excellent heat insulation performance, without using any chlorofluorocarbon-based foaming agent causing a bad effect on ozone layer depletion and global warming, without causing the corrosion of foaming equipment, and without precipitating the catalyst even on mixing with a polyol, and a method for producing the polyurethane resin by using the same. <P>SOLUTION: The amine catalyst composition used for the production of the polyurethane resin contains an amine compound expressed by formula (1) [wherein, R<SB POS="POST">1</SB>is ethylene or 3-12C straight-chain or branched-chain alkylene], and a glycerin-based solvent. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
