Patent ID: 7968199

Claim:
A process for producing a sheet (F) bearing a coating (B), comprising 1. applying to an optionally pretreated surface (T1) of a backing sheet (T) a crosslinkable coating composition (K) comprising a free-radical crosslinkable component (KK), 2. subjecting the applied coating composition (K) to at least one of drying, partially crosslinking, or drying and partially crosslinking to produce a coating (KT) which is not fully crosslinked, 3. applying a pigmented coating composition (P) to the coating (KT) which is not fully crosslinked to produce a coating (PB), and 4. applying a tiecoat (H) to the coating (PB) and drying the tiecoat (H), wherein the crosslinkable coating composition (K) produces a transparent coating (KE) after crosslinking to completion, wherein the crosslinkable coating composition (K) comprising the free-radically crosslinkable component (KK) comprises (i) one or more oligourethane (meth)acrylates, one or more polyurethane (meth)acrylates, or one or more oligo- and polyurethane (meth)acrylates, (ii) a number-average molecular weight of from 1000 to 50 000 g/mol, and (iii) a double bond content of from 1.0 to 5.0 mol of double bonds per 1000 g of reactive component (KK), wherein the free-radically crosslinkable component (KK) comprises (iv) greater than 1 branching point per molecule, (v) 5%-50% by weight, based on the weight of component (KK), of cyclic structural elements, (vi) at least one aliphatic structural element comprising at least 6 carbon atoms in the chain, and (vii) carbamate, biuret, allophanate, urea, amide, or a combination comprising two or more of the foregoing groups.
