The invention relates to the use of a molding composition which comprises at least 50% by weight of a copolyamide, which is composed of the following monomer combination: a) from 65 to 99 mol % of a substantially equimolar mixture composed of an unbranched aliphatic diamine having from 6 to 18 carbon atoms and of an unbranched aliphatic dicarboxylic acid having from 6 to 18 carbon atoms,  where the mixture composed of diamine and dicarboxylic acid comprises an average of from 8 to 12 carbon atoms, b) from 1 to 35 mol % of a substantially equimolar mixture composed of a cycloaliphatic diamine having from 8 to 20 carbon atoms and of a dicarboxylic acid having from 6 to 18 carbon atoms, for production of a printable or printed item, such as a ski topcoat.
