ABSTRACT:
A hardening type reactive particles which contain a carbodiimide compound in such a way to have the reactive performance the carbodiimide group inherently has only in the surface layer section or both surface layer section and inside of the base particle, without deforming shape of the base particle. The hardening type reactive particles each comprising a base particle (A) of thermoplastic resin having a functional group and carbodiimide compound (B) impregnated only in the surface layer section or both surface layer section and inside of the base particle, wherein the base particle (A) and carbodiimide compound (B) are strong bonded to each other by the crosslinking reaction taking place under heating between the functional group in the former and carbodiimide group in the latter, and a process for producing the same.
