    摘要： The present invention relates to α-aminoacetophenones functionalised with organic diisocyanates, having general structure (I) which can be used as reactive photoinitiators; to oligomers and polymers to which such functionalised α-aminoacetophenones are bonded; to α-aminoacetophenones having an unsaturated polymerisable side-chain; to dimeric and trimeric photoinitiators; to the use of such photoinitiators; to materials coated with such photoinitiators; and to the use of functionalised α-aminoacetophenones for modifying surfaces. In said structure (I), X is bivalent -O-, -NH-, -S-, lower alkylene or (a); Y is a direct bond or -O-(CH2)n- wherein n is an integer from 1 to 6 and the terminal CH2 group of which is linked to the adjacent X in formula (I); R is H, C1-C12alkyl, C1-C12alkoxy, C1-C12alkylNH- or -NR1AR1B wherein R1A is lower alkyl and R1B is H or lower alkyl; R1 is linear or branched lower alkyl, lower alkenyl or aryl-lower alkyl; R2 independently of R1 has the same definitions as R1 or is aryl, or R1 and R2 together are -(CH2)m- wherein m is an integer from 2 to 6; R3 and R4 are each independently of the other linear or branched lower alkyl that may be substituted by C1-C4alkoxy, or aryl-lower alkyl or lower alkenyl; or R3 and R4 together are -(CH2)z-Y1-(CH2)z- wherein Y1 is a direct bond, -O-, -S- or -NR1B-, and R1B is H or lower alkyl and z is independently of the other an integer from 2 to 4; R5 is linear or branched C3-C18alkylene, unsubstituted or C1-C4alkyl- or C1-C4alkoxy- substituted C6-C10arylene, or unsubstituted or C1-C4alkyl- or C1-C4alkoxy-substituted C7-C18aralkylene, unsubstituted or C1-C4alkyl- or C1-C4alkoxy-substituted C13-C24- arylenealkylenearylene, unsubstituted or C1-C4alkyl- or C1-C4alkoxy-substituted C3-C8-cycloalkylene, unsubstituted or C1-C4alkyl- or C1-C4alkoxy-substituted C3-C8cycloalkylene-CyH2y- or unsubstituted or C1-C4alkyl- or C1-C4alkoxy-substituted -CyH2y-(C3-C8-cycloalkylene)-CyH2y-, wherein y is an integer from 1 to 6; and D is an isocyanato group.
