    摘要： Novel classes of polymeric mordants based upon poly(vinylpyridine), poly(N-vinylimidazoles), and poly(meth)acrylates are disclosed. The polymeric mordants contain N-heterocycles which are N-quaternized by different types of alkylated hydrazones, semicarbazones, and multiple-quaternized alkylated salts serving as pendant groups.
