Claim 11:
12. A composite (F1B1) comprising:
a substrate (F1), and
an at least partially embossed and at least partially cured coating (B1), and which is producible by at least partially curing a coating composition (B1a), applied to at least a part of a surface of the substrate (F1) and at least partially embossed, by radiation curing, where the coating composition (B1a) is a radiation-curable coating composition,
wherein the radiation-curable coating composition (B1a) comprises:
at least a component (a) in an amount in a range from 40 to 95 wt %,
at least an additive as component (b) in an amount in a range from 0.01 to 5 wt %,
at least a photoinitiator as component (c) in an amount in a range from 0.01 to 15 wt %, and
at least a component (d), comprising at least one carbon double bond, in an amount in a range from 0 to 45 wt %,
where (i) the components (a), (b), (c), and (d) are each different from one another, (ii) the stated amounts of the components (a), (b), (c), and (d) are each based on a total weight of the coating composition (B1a), and (iii) the amounts of all components present in the coating composition (B1a) add up to 100 wt %,
and where component (a) comprises at least three structural units, each different from one another or at least partially identical, of formula (I), in which
radicals R1 in each case independently of one another are a C2-C8 alkylene group,
radicals R2 in each case independently of one another are H or methyl, and
m each independently of one another are an integral parameter in a range from 1 to 15, but with proviso that m is at least 2 in at least one of the structural units of formula (I) within the component (a);
wherein the number of ether groups of the general formula —O—R1— within the component a) is in a range of from 4 to 18.
