    Abstract: The invention provides coating material compositions comprising stable adducts which, at relatively high temperatures, generate radicals that possess initiating activity, and also provides processes for preparing them, and for the use of such coating material compositions. Stable adducts of this kind may be used in order to initiate polymerization of ethylenically unsaturated monomers.

    Radiation-hardenable aqueous polyurethane dispersion, useful as coating mass, comprises: compounds e.g. with free isocyanides-, reactive isocyanides- and acid groups; basic compounds; polyisocyanates; additives; water; and di-/polyamines

    Abstract: Radiation-hardenable aqueous polyurethane dispersion (A) comprises: a compound with two free isocyanate-, allophanate (bonded) group, radical polymerized C=C double bond; compound with isocyanate reactive group and radical polymerized C=C double bond; optionally compound with at least two isocyanate reactive groups; compound with isocyanate reactive- and acid group; basic compound; optionally a different compound that has isocyanate reactive group; water; optionally: different polyisocyanate; additives and di- and/or polyamine (where (A) does not contain thermal initiators). Radiation-hardenable aqueous polyurethane dispersion (A) comprises: (a) at least one compound with at least two free isocyanate group, at least one (bound) allophanate group, and radical polymerized C=C double bond, which is directly bounded to double bond of a carbonyl group or oxygen atom in bound ether group; (b) at least one compound with at least one isocyanate reactive group and at least one radical polymerized C=C double bond; (c) optionally at least one compound with at least two isocyanate reactive group of hydroxyl-, mercapto-, primary- and/or secondary amino groups; (d) at least one compound with at least one isocyanate reactive group and at least one acid group; (e) at least one basic compound of partially neutralized acid groups of (d); (f) optionally compound of (b), (d) and/or (e) that has only one isocyanate reactive group; (g) optionally at least one different polyisocyanate of (a); (h) optionally further additives such as reactive solvents, photo initiators or lacquer additives; (i) water; and (j) optionally at least one di- and/or polyamine (where (A) does not contain thermal initiators). Independent claims are included for: (1) a coated substrate comprising (A); and (2) a method for coating substrates comprising applying (A) on the substrate, drying and radiation hardening.
