Process for producing protective or surface coatings by coating of substrates with a radiation curable coating composition and subsequent radiation curing, wherein the radiation curable coating composition comprises a compound of the formula I in which R1 and R2 independently of one another are an organic radical having in each case at least one C atom, but where the sum of the C atoms of R1 and R2 is at least 4, or R1 and R2 together form a ring system comprising at least 4 C atoms, R3 is a hydrogen atom or Y, X is a C1 to C10 alkylene group, n and m independently of one another are 0 or an integer from 1 to 50, Y is a group selected from —CH═CH2; —CH2—CH═CH2; or and R4 can be an H atom, a methyl group or —CH2—C(═O)—OH, and R5 is an H atom and R6 is a —C(═O)—OH group or, alternatively, R6 is an H atom and R5 is a —C(═O)—OH group. |
