Abstract:
1. A UV-crosslinkable and meltable pressure-sensitive adhesive composition comprising (i) mixtures of UV-crosslinkable polyacrylate polymers, selected from (ii) at least one UV stabilizer which is present in the composition with a defined concentration which is harmonized with the concentration of the photoinitiator and is dependent on the ratio of the absorption maxima according to formulae 1 and 2 below, which are each applied subject to conditions I) and II): I) the wavelength of the absorption maximum of the UV stabilizer and of the photoinitiator are different by plus/minus less than 50 nm, where c is the concentration of the respective substance in mol/100 g polymer, II) the wavelength of the absorption maximum of the UV stabilizer and of the photoinitiator are different by plus/minus greater than or equal to 50 nm, where c is the concentration of the respective substance in mol/100 g polymer.
