Aqueous polymer compositions and their use as coatings are disclosed. A composition includes at least one polyurethane (meth)acrylate A and at least one compound B having a molecular weight of below 1000 g/mol and having at least two ethylenically unsaturated double bonds per molecule. The polyurethane (meth)acrylates A include the following components: component A1 includes at least one polyisocyanate A1a and at least one diisocyanate A1b; component A2 includes at least one compound having at least one ethylenically unsaturated double bond, and at least one functional group F; component A3 includes at least one neutral polyol including at least one aliphatic, polymeric polyol A3a and at least one low molecular weight diol A3b; component A4 includes at least one compound having at least one ionic or ionizable group I' and at least one functional group F&#x2032;; and component A5 includes at least one poly-C-Calkylene ether.

Aqueous polymer compositions comprising polyurethane (meth)acrylates

The invention relates to aqueous polyurethane dispersions that are curable with UV radiation. The polyurethanes are chain-extended with aromatic, cycloaliphatic or aliphatic diamine compound and cross-linked with aliphatic triamine compound. The polyurethanes are useful dispersions for coating various substrates. The use of the invented dispersions results in high hardness, very good flexibility and good chemical resistance in both clear coats and pigmented coatings before and after UV curing combined with very good adhesion to different substrates.

Continuous recovery of raw materials from coated films and apparatus for this purpose and film material recovered therewith. Large amounts of coated films can be fed to a continuous recycling process in which any pigments present in the coating and the substrate material are recovered. The treatment is carried out at room temperature in an alkaline medium consisting of soft soap, organic solvent and/or water, with or without the use of a catalyst. The solvent is recycled. After the first treatment stage, the film shreds can be treated in a second stage with a solvent/water mixture similarly to the first stage, and thorough final washing in a water or solvent circulation is effected in a third stage. The recovered film shreds are dried, pressed, milled and brought to the desired shape in a plastics agglomerator, and the recovered pigments are dried under reduced pressure (FIG.,). The process and apparatus can be used with advantage for any type of substrate or printed media, for example for magnetic substrates, photographic substrates, printing plates, pigment-free substrates.
