摘要

Aqueous preparation (I) comprises at least a polyurethane with a low glass transition temperature of -50[deg]C to 30[deg]C and an average particle size of 10-260, preferably 40-80 nm; at least a pearl polymer with a glass transition temperature of 40-140[deg]C, preferably 90-110[deg]C and a particle size of 2-40, preferably 6-15 mu m; optionally silicic acid (0-5, preferably 0-3%) with an average particle size of 1-10 mu m; and optionally other auxiliary agent and additive. An independent claim is included for a substrate, preferably textile, leather, metal, plastic, wood, paper or cardboard coated with (I).
