In a flexible layer composite comprising a support and at least one curable surface coating composition applied to the support, the layer of curable surface coating composition comprises a binder which contains double bonds and has a double bond density in the range from 3 mol/kg to 6 mol/kg, a transition glass temperature Tg in the range from −15° C. to 20° C. and a solids content in the range from 40% to 100%, if appropriate at least one surface coating auxiliary, preferably a surface coating auxiliary combination, if appropriate solvents and if appropriate pigments and/or fillers and is not sticky after thermal drying. At least one removable protective layer, preferably a removable protective film, has preferably been applied to the layer of curable surface coating composition.
