A process for the production of coatings with scratch-resistant durable surfaces that comprise as photoinitiator (B) in a photocurable formulation at least one surface-active photoinitiator, concentrated at the surface of the formulation, of formula (Ia) or (Ib), wherein Ra is a radical of formula (IIa), Rb is a radical of formula (IIb)), or Ra and Rb are naphthyl, anthracyl, phenanthryl or a heterocyclic radical each of which is unsubstituted or substituted; R1, R2, R3, R4, R5, R6, R7, R8, R9 and R10 are, for example, each independently of the others hydrogen; A-Y; C1-C12alkyl, halogen or phenyl; R11 and R12 are, for example, C1-C12 alkyl; X is —OR20 or —N(R21)(R22); R20 is, for example, hydrogen or C1-C4alkyl; R21 and R22 are, for example, hydrogen or C1-C12 alkyl; X1 is, for example, —O—; Y is, for example, a single bond or —O—; Y1 is, for example, a single bond; and A is, for example, C6-C30alkyl.
