<p>Compounds of the formula (I) are suitable photoinitiators which accumulates at the surface of the formulation (I), in which R is for example phenyl and A is a surface-active radical of the formula (III), Y is a divalent group C3-C12cycloalkylene, C6-C12bicycloalkylene; C1-C6alkylene-C3-C12cycloalkylene, C1-C6alkylene-C6-C12bicycloalkylene or C1-C10alkylene interrupted by one or more non-consecutive C3-C12cycloalkylene, -U-C3-C12Cycloalkylene, C6-C12bicycloalkylene or -U-C6-C12bicycloalkylene; C1-C10alkylene interrupted by one or more non-consecutive O and C3-C12Cycloalkylene, -U-C3-C12cycloalkylene, C6-C12bicycloalkylene and/or -U-C6-C12bicycloalkylene; -(CH2)a-CH-CH2-OH or -(CH2)b-O-(CH2)a-CH-CH2-OH; or -(CH2)a-CH(OH)-CH2- or -(CH2)b-O-(CH2)a CH(OH)-CH2-. U is U' or U' U' is -(CH2)aCOO-; U' is -Si(CH3)(CH3)- or -(CH2)a-Si(CH3)(CH3)- , a is a number from 1 to 10; b is a number from 0 to 10; with the proviso that they are, however, at least 1 if the methylene group in question is between two oxygen atoms .</p> |
