Abstract

Pigment printing pastes and dyeing liquors containing finely divided solid dispersions of polyisocyanates which have been deactivated on the surface and have a melting point about 25.degree. C. and a particle size of from 0.1 to 15 .mu.m as crosslinking agents in an amount of from 0.1 to 6% by weight. The textile materials printed or dyed with these pastes or liqu0rs, respectively, possess good fastness properties
