To provide a catalyst composition for polyurethane resin production, which has high gelling reactivity even in the coexistence of water, which is stable enough to be stored for a long period of time in a polyol premix containing water, and which does not contain a harmful metal compound such as a tin or lead compound, and a method for producing a polyurethane resin using the catalyst composition.
A composition comprising an iron compound represented by the formula (1) and a tertiary amine compound represented by the formula (3) is used as a catalyst for polyurethane resin production. In the formula (1), L is a β-diketonate ligand represented by the formula (2), and n is 2 or 3. In the formula (2), each of R1 and R3 is a C1-10 alkyl group, and R2 is a hydrogen atom or a C1-7 alkyl group. In the formula (3), each of R4 to R6 is a hydrogen atom or a C1-10 alkyl group, and R7 is a C1-10 alkylene group.
