Abstract
Abstract Colorant preparations, in particular printing inks, contain compounds of the formula ##STR1## in which the substituents have the meanings given in the description as an additive. The additive substantially prevents the undesirable "build-up" in printing.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
155 words
Offset printing inks comprising (1) a vehicle, (2) a colorant, and (3) an additive compound, said additive compound being in the offset printing ink in an amount effective to substantially prevent undesirable build-up of the offset printing ink during offset printing, and said additive compound having the formula (A) ##STR37## in which R 1 and R 2 independently of one another and independently of each recurring unit, denote H, C 1-24 -alkyl, aryl or C 1-24 -alkaryl, R 3 denotes H, C 1-24 -alkyl, aryl, C 1-24 -alkaryl--where R 3 can, if desired carry 1-3 further substituents from the series comprising--O--R 1 , --NR 1 R 2 or radicals ##STR38## Y 1 denotes O, S, NR 1 , X, independently of each recurring unit, denotes O, S, ##STR39## where R 4 is H, C 1-24 -alkyl, aryl, C 1-24 -alkyl-aryl or ##STR40## n denotes an integer from 2-4 and m denotes an integer from 3-450.
