摘要： Preparation of radiation-curing allophanate-containing prepolymers comprises using diisocyanates, hydroxy-functional compounds, which contain groups, which react, with polymerization, with ethylenically unsaturated compounds on exposure to actinic radiation, and polyester, polyether, or polycarbonate polyols having a functionality of >=1.9 and a number-average molecular weight of >=1000 g/mol, in the presence of an allophanatization catalyst to give allophanate-containing prepolymers. Preparation of radiation-curing allophanate-containing prepolymers having residual monomer contents of less than 0.5 wt.% and isocyanate (NCO) content of less than 1 wt.%, comprises using (A) diisocyanates, (B) hydroxy-functional compounds, which contain groups, which react, with polymerization, with ethylenically unsaturated compounds on exposure to actinic radiation, and (C) polyester, polyether, or polycarbonate polyols having a functionality of >=1.9 and a number-average molecular weight (M n) of >=1000 g/mol, (D) optionally in the presence of a catalyst, to form NCO-group-containing prepolymers having radiation-curing groups, which are subsequently reacted optionally after addition of monofunctional isocyanates, in the presence of an allophanatization catalyst to give allophanate-containing prepolymers, where the ratio of NCO groups of the compounds from (A) to the hydroxyl (OH) groups of the compounds from (B) and (C) is 1.45:1.0-1.1:1.0 and the ratio of OH groups from (B) to the OH groups from (C) is 8.0:1-1.5:1. An independent claim is included for coating compositions comprising radiation-curing allophanate-containing prepolymer(s); optionally polyisocyanate(s) containing free or blocked isocyanate groups, which are free from groups, which react, with polymerization, with ethylenically unsaturated compounds on exposure to actinic radiation; optionally other compounds, different from radiation-curing allophanate-containing prepolymer, which contain groups, which react, with polymerization, with ethylenically unsaturated compounds on exposure to actinic radiation, and optionally contain free or blocked NCO groups; optionally isocyanate-reactive compound(s) containing active hydrogen; optionally initiators; and optionally auxiliaries and additives.

摘要： Lacquer composition comprises one or more first and second compound containing different chemical functions and optionally containing ethylenically unsaturated double bond; optionally ethylenically unsaturated compounds exhibiting no chemical functions that are suitable for polyaddition; photoinitiators; additives such as stabilizers, catalysts and other auxiliary materials; and non-functional polymers and/or fillers, where none of the component exhibits an average functionality of more than 2.8 during cross-linking by polyaddition reaction. Lacquer composition comprises one or more first compound containing different chemical functions and optionally containing ethylenically unsaturated double bond; one or more second compound containing different chemical function and optionally containing ethylenically unsaturated double bond (where at least one of the compounds contain ethylenically unsaturated double bond, and the compound undergoes polyaddition with each other); optionally ethylenically unsaturated compound exhibiting no chemical functions that are suitable for polyaddition; photoinitiators; additives such as stabilizers, catalysts and other auxiliary materials; and non-functional polymers and/or fillers, where none of the component exhibits an average functionality of more than 2.8 during cross-linking by polyaddition reaction. An independent claim is included for a substrate coated with the lacquer.
