Abstract
The invention provides dispersing resins for solids, obtainable by full or partial reaction of A) one or more amino-functional polymers with B) one or more polyesters of the general formula (I)/(Ia) T-C(O)—[O-A-C(O)]x—OH (I) T1-O—[C(O)-A-O—]y—Z (Ia) and C) one or more polyethers of the general formula (II)/(IIa) T2-B—Z (II) T-O—B—Z (IIa).
Claims25
A dispersing resin obtainable by full or partial reaction of
- A) one or more amino-functional polymers with
- B) one or more polyesters of the general formula (I)/(Ia)
- T-C(O)—[O-A-C(O)]x—OH (I)
- T-O—[C(O)-A-O—]y—Z (Ia)
- and
- C) one or more polyethers of the general formula (II)/(IIa)
- T-C(O)—B—Z (II)
- T-O—B—Z (IIa)
- in which
- T is a hydrogen and/or a substituted or unsubstituted, linear or branched aryl, arylalkyl, alkyl or alkenyl radical wherein the alkyl or alkenyl radical has 1 to 24 carbon atoms,
- A is at least one divalent radical selected from the group consisting of linear, branched, cyclic, and aromatic hydrocarbons,
- Z is at least one radical selected from the group consisting of sulfonic acids, sulfuric acids, phosphonic acids, phosphoric acids, carboxylic acids, isocyanates, and epoxides,
- B is a radical of the general formula (III)
- —(CLH2LO)a—(CmH2mO)b—(CnH2nO)c—(SO)d— (III)
- a, b, and c independently of one another are values from 0 to 100, with the proviso that the sum of a+b+c≧0 and that the sum of a+b+c+d>0
- d≧0
- L, m, and n independently of one another are ≧2
- x and y independently of one another are ≧2.
