摘要：
Crosslinked (meth)acrylamide particles in the form of substantially spherical fine particles having particle sizes of from 1 to 1000 μm made of a polymer of a N-alkoxymethyl(meth)acrylamide and a polyfunctional unsaturated monomer copolymerizable with the N-alkoxymethyl(meth)acrylamide, wherein the structural units derived from the N-alkoxymethyl(meth)acrylamide are crosslinked by a crosslink having a structure represented by the formula 1 (wherein X is hydrogen or a methyl group, and each of R8 and R9 is another structural unit derived from the N-alkoxymethyl(meth)acrylamide and bonded to the nitrogen atom in another structural unit derived from the N-alkoxymethyl(meth)acrylamide monomer via a methylene group).
