(57) [Summary] (Correction) [Problem] It is possible to stably store without exhibiting a catalytic action at room temperature, and when heated at the time of molding, an excellent catalytic action is exerted to obtain good moldability and A latent catalyst capable of giving a high-quality molded product, and a resin composition. A latent catalyst comprising phosphonium borate represented by the general formula [1]. (In the formula, R 1 to R 4 are monovalent organic groups or monovalent aliphatic groups. Y 1 , to Y 4 are monovalent organic groups or monovalent aliphatic groups. , At least one of them is Aromatic polycarboxylic acid having two or more carboxyl groups in the molecule, 1 Aromatic carboxylic acid having at least one acid anhydride group and one carboxyl group in the molecule, 1 A proton donor selected from the group of polyhydric phenol compounds having two or more hydroxyl groups in the molecule and aromatic compounds having at least one carboxyl group and one phenolic hydroxyl group in one molecule releases one proton. It is a group that is made. ) |
