Abstract: A water dispersible, radiation curable polyurethane comprises organic aliphatic or alicyclic polyisocyanates, cycloaliphatic diols and/or cycloaliphatic diamines, compounds having at least one isocyanate reactive group and at least one radically polymerizable unsaturated group and compounds having at least one isocyanate reactive group and at least one dispersion aiding group. A water dispersible, radiation curable polyurethane (I) comprises: (A) organic aliphatic or alicyclic polyisocyanates; (B) cycloaliphatic diols and/or cycloaliphatic diamines; (C) compounds having at least one isocyanate reactive group and at least one radically polymerizable unsaturated group; (D) compounds having at least one isocyanate reactive group and at least one dispersion aiding group; (E) optionally compounds having at least two isocyanate reactive groups having a mol. wt. of less than 1000 g/mol; (F) optionally compounds having at least one isocyanate reactive group that are different to (A)-(D). Independent claims are included for: (i) a polyurethane dispersion (II) comprising the polyurethane (I) and optionally 0-10 wt.% of a photochemical and/or thermal initiator and 0-10 wt.% of a UV absorber and a HALS compound; (ii) a process for the coating of substrates by application of the polyurethane dispersion (II), optionally containing conventional paint additives, onto a substrate and curing by means of electron irradiation or UV light under oxygen, or preferably under inert gas; (iii) the resulting coated substrate.

Abstract: The invention relates to a method for the production of adhesive-free, reduced-migration and reduced-yellowing coatings, in particular Foliendeckstrichen. Inventive coating materials containing less than 0.1 weight % of a photoinitiator and even in the absence of a photoinitiator can be hardened by exposure to UV-radiation, if the coating materials contain (meth)acrylate groups (A) and >CH-O-ether structure units (B) in certain minimum amounts, whereby (A) and (B) can also be accommodated in one molecule or in different molecules. The method exhibits many economic, technical and toxicological advantages due to said reduction of the amount of photoinitiators or the absence of photoinitiators.

Abstract: A process for the production of (meth)acrylate esters (I) by esterification of (meth)acrylic acid (II) with mono- or poly- hydric alcohols (III) is claimed. The reaction mixture, still containing (II) in amounts equivalent to an acid number of at least 5 mg KOH/g, is treated with amino compound(s) (IV) containing at least one prim., sec. or tert. amino group. Also claimed are: (1) esters (I) obtained by this process; and (2) radiation-curable materials (RCM) containing (I).

Abstract: Radiation-curable compsns. (I), contg. (a) radiation-curable, radically-polymerisable cpds. and (b) capped amino cpds. which are surface-active in cpds. (a) and which release amino cpds. with free prim. and/or sec. amino gps. when irradiated with high-energy light, the total no. of H atoms contained in amino gps. being at least 2. Also claimed is (i) a process for the prodn. of (I) by adding cpds. (b) to cpds. (a); (ii) a process for the prodn. of coatings or mouldings by irradiating (I) with high-energy light; (iii) moulded prods. or coatings obtd. by this process.
