Abstract:
To provide a novel cyclic amine compound and a process for producing a polyurethane resin by using it. A 3-hydroxy-1,5-diazabicyclo[3.2.2]nonane represented by the following formula (1), and a process for producing a polyurethane resin by using a catalyst for producing a polyurethane resin, which contains the 3-hydroxy-1,5-diazabicyclo[3.2.2]nonane. When the compound represented by the formula (1) has optical isomers, diastereomers or geometric isomers, the compound includes both a mixture of any of them and an isolated isomer of any of them. [in the above formula (1), each of R1, R2, R3, R4, R5, R6, R7 and R8 which are independent of one another, is a hydrogen atom, a C1-4 alkyl group, a hydroxy group, a hydroxymethyl group or a C1-4 alkoxy group.]
