An amine functional compound comprising i. least one segment consisting of at least one ether unit E and at least one ester unit, wherein the ether units and ester units are connected by an ether link or by an ester link, and wherein the sum of the number of ether units and ester units is at least three, and wherein the ether units and ester units are arranged in random order, and ii. at least one amine group ii. selected from a tertiary amine group, a salt of a tertiary amine group and a quaternary ammonium group, wherein the at least one segment is covalently linked to a polymerization starter moiety comprising the at least one amine group ii.
First claim
Opening claim text (preview).
The invention claimed is: 1. An ink or coating composition comprising pigment particles and an amine functional compound comprising i. at least one segment comprising at least one ether unit and at least one ester unit, wherein the at least one ether unit and the at least one ester unit are connected by an ether link or by an ester link, and wherein the sum of the number of the at least one ether unit and the at least one ester unit is at least three, and wherein the at least one ether unit and the at least one ester unit are arranged in random order, and ii. at least one amine group ii. selected from a tertiary amine group, a salt of a tertiary amine group and a quaternary ammonium group, wherein the at least one segment is covalently linked to a polymerization starter moiety comprising the at least one amine group ii. 2. The composition according to claim 1 , wherein the polymerization starter moiety is directly linked to said at least one segment via one or more selected from an ether group, an ester group, a secondary amide group, a tertiary amide group, a secondary amine group and a tertiary amine group. 3. The composition according to claim 1 , wherein the polymerization starter moiety comprises a polyethylenimine. 4. The composition according to claim 1 , wherein the at least one ether unit includes a unit of formula (IV) —[CR 30 2 ] n —O—, wherein n is an integer of 2 or 3, and R 30 independently of each other represent organic groups having 1 to 25 carbon atoms or hydrogen. 5. The composition according to claim 1 , wherein the at least one segment has a molar ratio between the at least one ether unit and the at least one ester unit in the range 19:1 to 1:1. 6. A composition comprising pigment particles and an amine functional compound, the amine functional compound being included in an amount ranging from 1 to 50 wt. % based on the weight of the pigment, the amine functional compound comprising i. at least one segment comprising at least one ether unit and at least one ester unit, wherein the at least one ether unit and the at least one ester unit are connected by an ether link or by an ester link, and wherein the sum of the number of the at least one ether unit and the at least one ester unit is at least three, and wherein the at least one ether unit and the at least one ester unit are arranged in random order, ii. at least one amine group ii. selected from a tertiary amine group, a salt of a tertiary amine group and a quaternary ammonium group, wherein the at least one segment is covalently linked to a polymerization starter moiety comprising the at least one amine group ii. 7. The composition according to claim 6 , wherein the polymerization starter moiety is directly linked to said at least one segment via one or more selected from an ether group, an ester group, a secondary amide group, a tertiary amide group, a secondary amine group and a tertiary amine group. 8. The composition according to claim 6 , wherein the polymerization starter moiety comprises a polyethylenimine. 9. The composition according to claim 6 , wherein the at least one ether unit includes a unit of formula (IV) —[CR 30 2 ] n —O—, wherein n is an integer of 2 or 3, and R 30 independently of each other represent organic groups having 1 to 25 carbon atoms or hydrogen. 10. The composition according to claim 6 , wherein the at least one segment has a molar ratio between the at least one ether unit and the at least one ester unit in the range 19:1 to 1:1.
