Compositions for treating leather containing aqueous polymer dispersions, film-forming in the absence of an organic solvent

摘要

Leather treatment composition, comprises an aqueous dispersion of particles of at least two polymer phases, the first internal formed by a soft polymer with Tg less than 20[deg]C and the second external formed by a hard polymer with Tg greater than 60[deg]C and able to contain reactive functional monomers and optionally a crosslinking agent for them. The aqueous dispersion comprises 10-80 wt.% and the crosslinking agent 0-20 wt.% of the composition : Independent claims are included for: (1) a leather treatment product; and (2) a leather treated with the composition or treatment product.
