Abstract
In order to offer coatings with improved resistance to solvents which can be prepared by cationic polymerization under irradiation, the choice is made of a composition comprising at least one monomer, oligomer or polymer of general formula (I): in which:A1 is chosen from polyester blocks, polyurethane blocks, hydrocarbon-comprising backbones of mono- or polycarboxylic acid and addition products of a polycarboxylic acid and of a cycloaliphatic diepoxide,m is a number from 1 to 6,R1 is a cycloaliphatic group carrying a hydroxyl group situated in the a position with respect to the oxygen atom to which R1 is bonded,R2 is a second cycloaliphatic group carrying an oxirane group situated at the chain end, andB is chosen from one or more covalent bonds, an oxygen atom and linear, branched or cyclic hydrocarbon-comprising radicals.
