Abstract

Procedure for finishing leather and synthetic leather substitute, characterized in that a mixture of polyols and polyisocyanates dissolved in solvents is applied, in which crosslinking is verified during and after the evaporation of the solvent, the polyols being constituted (I) by copolymers that, based on the total amount of monomers, are composed of: a) 4 to 20% by weight of copolymerizable ethylenically unsaturated compounds and containing hydroxylic groups. b) 80 to 96% by weight of other ethylenically unsaturated copolymerizable compounds bearing inert groups against isocyanate groups, and c) 0 to 13% by weight of dyes bearing at least one ethylenically unsaturated copolymerizable group, and the polyisocyanates (II) consist of isocyanurate-isocyanate containing aromatic groups of high molecular weight.
