Abstract
A latent curing catalyst includes zirconium phosphate fine particles containing a curing accelerator. The zirconium phosphate fine particles containing the curing accelerator do not have a sharp crystalline peak at a diffraction angle (2θ) in a range of 10° to 40° in powder X-ray diffraction and have a broad halo pattern.

A latent curing catalyst comprising zirconium phosphate fine particles containing a curing accelerator, wherein the zirconium phosphate fine particles containing the curing accelerator do not have a sharp crystalline peak at a diffraction angle (2θ) in a range of 10° to 40° in powder X-ray diffraction and have a broad halo pattern.
A method for producing zirconium phosphate fine particles containing a curing accelerator, comprising:
- (a) dissolving a zirconium salt of a fatty acid or a zirconium alkoxide in a solvent to obtain a solution;
- and
- (b) mixing the solution obtained in the step (a) with phosphoric acid to obtain zirconium phosphate fine particles;
- and
- (c) mixing a medium containing the zirconium phosphate fine particles with a curing accelerator to obtain zirconium phosphate fine particles containing the curing accelerator.
