ABSTRACT:
Flaky particles which are produced through easy conversion from mother particles by using an organic compound other than monomers having double bonds as the hardening and crosslinking agent and to which at least one mechanical or functional characteristic selected from among reactivity, close adhesion, and tackiness is imparted by the presence of part of the unreacted reactive groups of the organic compound inside and on the particles; and a process for the production of the flaky particles. More specifically, flaky particles composed of mother particles (A) having functional groups and an organic compound (B) which has groups reactive with the functional groups of the particles (A) and is soluble in a solvent, characterized in that at least part of the functional groups of the mother particles (A) and at least part of the reactive groups of the organic compound (B) react with each other to form crosslinks.
