Document Type and Number:
Japanese Patent JP4053612
Kind Code:
B2
Abstract:
Compounds of the formulae I or 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 indices n, independently of one another are 0 or 1; R is H, C1-C12-alkyl, C1-C12-alkoxy or C1-C12-alkylNH-; R 1 and R2, independently of one another, are H, linear or branched C1-C8-alkyl, C1-C8-hydroxyalkyl, or C6-C10-aryl, or two groups R1 -(Y1)n- together are -(CH2)x-, or the groups R1-(Y1)n- and R2-(Y1)n - together form a radical of the formula R3 is a direct bond or linear or branched C1-C8-alkylene, which is unsubstituted or substituted by -OH and/or is optionally interrupted by one or more -O-, -O-C(O)- or -O-C(O)-O- groups; R4 is branched C3-C18-alkylene, C6-C10-arylene which is unsubstituted or substituted by C1-C4-alkyl or C1-C4-alkoxy, or C7-C18-aralkylene which is unsubstituted or substituted by C1-C4-alkyl or C1-C4-alkoxy, C3-C8-cycloalkylene which is unsubstituted or substituted by C1-C4-alkyl or C1-C4-alkoxy, C3-C8-cycloalkylene-CyH2y- which is unsubstituted or substituted by C1-C4-alkyl or C1-C4-alkoxy, or -CyH2y-(C3-C8- cycloalkylene)-CyH2y- which is unsubstituted or substituted by C1-C4-alkyl or C1-C4-alkoxy; each R5, independently of the others, is as defined for R4 or is linear C3-C18-alkylene; R6 is linear or branched C1-C6-alkyl; 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-C8-alkyl, C3-C8-cycloalkyl, benzyl or phenyl; with the provisos that n in the groups -(Y1)n-R1 is 0 if R2 is H; 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 0; at most one Y1 radical in the -(Y1)n- groups in the formula Ia is O and n in the other -(Y1)n- group is 0; and n in the -(Y2)n- group is 0 if R3 is a direct bond. The compounds are photoinitiators which can be functionalised by means of ethylenic groups or can be bonded to H-active substances in order, for example, to modify surfaces by means of photopolymerisable substances.
