Abstract:
A mixture of at least two compounds respectively comprising at least two double bonds. The mixture has a GFV 200-600 g/mol bond and at least two of the compounds respectively contain at least two (Meth)acrylic acid esters as double bond components . GFV represents the following: (cf formula (I)); alphai corresponds to the molar fraction of the compound (i) in the mixture, n corresponds to the number of compounds in the mixture and n is = 2, Zi corresponds to the number of double bonds in the compound (i), MWi corresponds to the molecular weight of the compound (i).

Abstract:
The invention relates to a multi-layer finish on a substrate, containing at least one radiation-curable paint system (F) and at least one elastic intermediate layer (D) which is located between the substrate and the radiation-curable paint system (F) and has a maximum glass transition temperature (Tg) of -20 DEG C.
Abstract:
UV- and heat-curable aqueous polyurethane dispersions comprise compounds attached via polyisocyanates and containing UV-polymerizable C=C double bonds, aliphatic diols incorporated by way of isocyanates and having a molecular weight of less than 500 g/mol, compounds attached via isocyanates and containing carboxylic acid or sulfonic acid groups and/or salts thereof, free hydroxyl groups, and compounds containing blocked isocyanate groups. They are suitable for coating heat-stable substrates such as metal substrates and may be used with advantage for automotive clearcoats.

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.
