Abstract

The invention relates to a polymer mixture, especially for decorative surfaces in an automobile interior, that displays an improvement in long-term functionality with respect to the properties of writing sensitivity, soiling and cleaning behavior, abrasion resistance, and antisqueak behavior, both in the delivery condition and in the used condition. The inventive polymer mixture comprises: 0%-50% by weight of at least one aqueous polyurethane dispersion and/or polyester dispersion and/or polyether dispersion and/or polyester-polyacrylate dispersion and/or polyacrylate-polyurethane dispersion and/or polyacrylate dispersion and/or of a dispersion based on at least one of these and/or several other polymers; 1%-60% by weight of at least one aqueous polyurethane dispersion and/or polyesterpolyol dispersion and/or polyetherpolyol dispersion and/or polyacrylatepolyol dispersion and/or of a dispersion based on at least one of these and/or two or more other polymers, the polymer or at least one polymer being functionalized with OH groups and/or NH groups and possessing an OH content or NH content of between 0.3% and 6.0% by weight, based on the nonvolatile fraction of the total amount of the polymers; 0%-40% by weight of at least one nonfunctionalized slip additive; 1%-40% by weight of at least one functionalized slip additive; 0.2%-50% by weight of at least one crosslinker or crosslinker system; 0%-75% by weight of at least one matting agent; 0%-50% by weight of diluent; 0%-50% by weight of other adjuvants, based on the nonvolatile fraction of the total amount of polymers.
