Abstract
Polymeric compositions which undergo crosslinking after drying at room temperature or elevated temperatures and are dissolved or dispersed in water are prepared by reacting polymeric organic compounds containing carbonyl and carboxyl groups with polyhydrazides in the presence of monoketones or monoaldehydes and are dissolved or dispersed in water by partially or completely neutralizing the carboxyl groups. They are useful as crosslinking agents and as binders for coatings on sheet-like substrates.
