COMPOSITIONS FOR TREATING LEATHER CONTAINING AQUEOUS POLYMER DISPERSIONS, FILM-FORMING IN THE ABSENCE OF ORGANIC SOLVENT

摘要

The invention concerns leather finish compositions containing at least an aqueous dispersion of film-forming polymer at room temperature without cosolvent, or plasticizing agent and optionally a cross-linking agent. Said dispersions free of organic solvent provide non-sticky and abrasion resistant coatings with good water resistance. Said dispersions consist of structured polymer particles having one or more soft phases (Tg < 20 DEG C) and one or more hard phases (Tg > 60 DEG C).
