The invention relates to a polymer mixture, in particular for decorative surfaces in an automobile interior, which shows improvement in the long-term usability with respect to the properties of writing sensitivity, soiling and cleaning behavior, abrasion resistance and anti-creak behavior in the delivery state and in the stressed state. The claimed polymer mixture is characterized by the following composition: 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 a dispersion on the basis of 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 polyacrylate polyol dispersion and/or a dispersion on the basis of at least one of these and/or several other polymers, wherein the polymer or at least one polymer is functionalized with OH groups and/or NH groups and has an OH content or NH content between 0.3 and 6.0% by weight, relative to the non-volatile portion of the total quantity of the polymers; 0 - 40% by weight of at least one non-functionalized glide additive; 1 - 40 % by weight of at least one functionalized lubricating additive; 0.2 - 50% by weight of at least one cross-linking agent or crosslinking system; 0 - 75% by weight of at least one matting agent; 0 - 50% by weight diluent; 0 - 50% by weight of further additives, relative to the non-volatile portion of the total quantity of the polymers.
