Functionalized photoinitiators, macromers thereof. and the use thereof. Abstract Compounds of the formula I or Ia Image (I), Image (Ia), in which X is O; Y is O, NH or NR6; Y1 is O; Y2 is -O-, -O-(O)C-, -C(O)-O- or -O-C(O)-O-; the n indices, independently of one another, are 0 or 1; R is H, C1-C12alkyl, C1-C12alkoxy or C1-C12alkyl-NH-; the R1 and R2 radicals, independently of one another, are H, linear or branched C1-C8alkyl, C1-C8hydroxyalkyl or C6-C10aryl, or two groups R1-(Y1)n- together are -(CH2)x-, or the R1-(Y1)n- and R2-(Y1)n- groups together form a radical of the formula Image ; R3 is a direct bond or linear or branched C1-C8alkylene, which is unsubstituted or substituted by -OH and/or is uninterrupted or interrupted by one or more -O-, -O-C(O)- or -O-C(O)-O- groups; R4 is branched C3-C18alkylene, C6-C10arylene which is unsubstituted or substituted by C1-C4alkyl or C1-C4alkoxy, C7-C18aralkylene which is unsubstituted or substituted by C1-C4alkyl or C1-C4alkoxy, C3-C8cycloalkylene which is unsubstituted or substituted by C1-C4alkyl or C1-C4alkoxy, C3-C8cycloalkylene-CyH2y- which is unsubstituted or substituted by C1-C4alkyl or C1-C4alkoxy, or -CyH2y-(C3-C8cycloalkylene)-CyH2y- which is unsubstituted or substituted by C1-C4alkyl or C1-C4alkoxy; each R5, independently of the others, has the same meaning as R4 or is linear C3-C18alkylene; R6 is linear or branched C1-C6alkyl; x is an integer from 3 to 5; y is an integer from 1 to 6; Ra and Rb, independently of one another, are H, C1-C8alkyl, C3-C8cycloalkyl, benzyl or phenyl; with the provisos that n in the -(Y1)n-R1 groups is 0 if R2 is H; that at most two Y1 radicals in the -(Y1)n- groups in the formula I are O and n in the other -(Y1)n- groups is O; that at most one Y1 in the -(Y1)n- groups in the formula Ia is O and n in the other -(Y1)n- group is O; and that n in the -(Y2)n- group is 0 if R3 is a direct bond. The compounds are photoinitiators which can be functionalized by means of ethylenic groups or can be bonded to H-active substances, in order, for example, to modify surfaces by means of photopolymerizable substances.
