ABSTRACT:
The invention relates to addition compounds of formula (1):in which: n is a number from 1 to 10; R1and R2are identical or different and are each a hydrogen atom or a saturated or unsaturated aliphatic radical having 1 to 4 carbon atoms; R3and R4are identical or different and are each a hydrogen atom or alkyl having 1 to 3 carbon atoms, and the bridge member (R3+R4) is in each case positioned ortho or meta in relation to the phenolic oxygen atom; Z represents a group —CH2—CH2—, —CH2—CH(CH3)—, —CH(CH3)—CH2— or a combination thereof; s is number from 1 to 200; B represents hydrogen, —CO—CH═CH—COOM, —COCH(SO3M)CH2COOM, —CO—CH2—CH(SO3M)—COOM, —SO3M, —SO2M and/or —PO3MM, whereby M is preferably a cation selected from the group Li+, Na+, K+, NH4+, HO—CH2—CH2—NH3+, (HO—CH2—CH2—)2NH2+or (HO—CH2—CH2—)3NH+; and Y is a radical of an amine. The inventive addition compounds are used as dispersing agents of solids, for example, pigments, particularly in aqueous media.
