A deformable film has a decorative surface featuring a completely matt appearance. For this purpose, the deformable film has a decorative surface provided with at least one coating comprising the following constituents: (a) an aqueous dispersion of a hydroxy-functional prepolymer, obtainable by conversion of at least one of the following components: (i) a component having hydroxyl groups, (ii) a polyester polyol having hydroxyl groups, (iii) a polyisocyanate having isocyanate groups, (iv) a compound having at least two groups reactive toward isocyanate groups and at least one group capable of anion formation, (v) water, where components (i) to (iii) and the ratio of components (i) to (iii) are selected such that an excess of hydroxyl groups is present relative to the isocyanate groups, and (b) nanoparticles having a number-average particle size of 1 to 1000 nm and (c) a crosslinker having at least two groups reactive toward hydroxyl groups.

Formable film

A method for making a plastic film having a three-dimensionally structured and colored surface includes the steps of: providing the film with a three-dimensional surface structure via a shaping process; determining the provided topography of the film surface via a scanning process; and, applying a coloring to the surface after the topography of the surface has been determined. A device configured to apply the coloring to the surface is controlled such that the application of the coloring to the surface is changeable in dependence upon at least one of topological data of the surface and macroscopic shapes of the surface.

Method for making a colored plastic film

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.
