    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: Curable polyurethane polymers (I) and their salts are novel in that the sum of the OH numbers of a component comprising a prepolymer(s) containing hydroxyl groups with ethylenically unsaturated double bond(s) capable of free radical photochemical polymerization, and a component containing isocyanate-reactive hydroxy groups or hydroxy groups and/or amino groups, is 121-300 mg KOH/g. Curable polyurethane polymers (I) and their salts comprise (A) 40-80 wt.% prepolymer(s) containing hydroxyl (OH) groups with alpha , beta -ethylenically unsaturated double bond(s) capable of free radical photochemical polymerization; (B) 0.1-20 wt.% compound(s) containing OH and/or primary or secondary amino group(s) reacting with isocyanate (NCO) groups and also polar functional group(s); (C) 0.1-10 wt.% diamine(s) and/or polyamine(s); (D) 0-20 wt.% other compound(s) with NOTLESS 2 NCO-reactive OH groups or OH and/or primary or secondary amino groups; (E) 0-20 wt.% other compound(s) with an NCO-reactive group; and (F) 10-50 wt.% polyisocyanate(s). The novelty is that the sum of the OH numbers of components (A) and (D) is 121-300 mg KOH/g. Independent claims are also included for (a) (I) dispersions; and (b) the production of (I) in which the polymers are prepared by (1) reacting components (A), (B), (F) and optionally (D) and/or (E) with an NCO polyurethane prepolymer; (2) optionally ionizing the ionogenic polar functional groups by neutralization and/or quaternization; (3) reacting the NCO prepolymer with (C) and optionally (E) to give a product free from NCO groups and optionally dispersing the product in water; and optionally (4) drying the reaction product, preferably by spray drying.

    Abstract: Compounds having isocyanate groups with or without blocking, allophanate groups and free-radically polymerizable C-C double bonds, the C-C double bonds being in activated form by virtue of a carbonyl group attached directly to them or by virtue of an oxygen atom in ether function (activated double bonds), derived from polyisocyanates and alcohols A which in addition to the alcohol group also carry an activated double bond (compounds I). The invention additionally relates to radiation-curable formulations and coating compositions comprising the compounds I, to methods for coating using these substances, and to coated articles produced using these methods. Furthermore, the invention relates to the use of the compounds I in radiation-curable compositions such as in casting compositions, dental compounds, composite materials, sealing compounds, adhesives, troweling compounds, printing inks, in photostructurable compositions such as solder resists, photoresists, photopolymeric printing plates, and stereolithography resins.
