Claims24
A method of dispersing a pigment comprising adding to the pigment an amide-modified resin or amide-modified hydrocarbyl moiety, obtained by modifying a resin, or a hydrocarbyl moiety, by reaction with one or mare compounds of the formula:
- R-Het-ALK-NH2
- wherein Het is a nitrogen-containing heterocyclic moiety;
- R represents at least one H, a C1-4 alkyl, or a C1-4 alkoxy;
- and
- ALK is a branched or unbranched C1-6 alkylene group,
- wherein the resin or hydrocarbyl moiety comprises a carboxylate group or a functional derivative thereof, wherein the resin is polyurethane, polyether, polyacrylate, polyamide, acrylic resin, polyester, terpene, or alkyd, and wherein the hydrocarbyl moiety is branched or unbranched C1-C25 carboxyalkylene, carboxyalkenylene, or carboxyalkynylene group, or a carboxylate functional derivative thereof which has at least 5 carbon atoms, and which may be substituted with an ester group.
A method of flushing a pigment comprising adding to the pigment a flushing agent comprising an amide-modified resin or amide-modified hydrocarbyl moiety, the amide-modified resin or amide-modified hydrocarbyl moiety obtained by modifying a resin or hydrocarbyl moiety by reaction with one or more compounds of the formula:
- R-Het-ALK-NH2 wherein Het is a nitrogen-containing heterocyclic moiety;
- R represents at least one of H, C1-4 alkyl, or C1-4 alkoxy;
- and ALK is a branched or unbranched C1-4 alkylene group,
- wherein the resin or hydrocarbyl moiety comprises a carboxylate group or a functional derivative thereof, and wherein the resin is polyurethane, polyether, polyacrylate, polyamide, acrylic resin, polyester, terpene, or alkyd and wherein the hydrocarbyl moiety is branched or unbranched C1-25 carboxyalkylene, carboxyalkenylene, or carboxyalkynylene group, or a carboxylate functional derivative thereof which has at least 5 carbon atoms, and which may be substituted with an ester group.
A coating or ink composition made by dispersing pigment in the composition using a dispersant comprising an amide-modified resin or amide-modified hydrocarbyl moiety, the amide-modified resin or amide-modified hydrocarbyl moiety obtained by modifying a resin or hydrocarbyl moiety by reaction with one or more compounds of the formula:
- R-Het-ALK-NH2 wherein Het is a nitrogen-containing heterocyclic moietys;
- R represents at least one of H, C1-4 alkyl, or C1-4 alkoxy and ALK is a branched or unbranched C1-6 alkylene group,
- wherein the resin or hydrocarbyl moiety comprises a carboxylate group or a functional derivative thereof, and wherein the resin is polyurethane, polyether, polyacrylate, polyamide, acrylic resin, polyester, terpene, or alkyd, and wherein the hydrocarbyl moiety is branched or unbranched C1-25 carboxyalkylene, carboxyalkenylene, or carboxyalkynylene.
A method of dispersing a pigment comprising adding to the pigment one or more amide-modified polyester resins of the following formula:
- Het-ALK-NH—CO—X wherein Het is a nitrogen-containing heterocyclic moiety;
- ALK is a branched or unbranched alkylene group with 1-4 C atoms;
- X is a polyester group.
A method of flushing a pigment comprising adding to the pigment a flushing agent comprising one or more amide-modified polyester resins of the following formula:
- Het-ALK-NH—CO—X wherein Het is a nitrogen-containing heterocyclic moiety;
- ALK is a branched or unbranched alkylene group with 1-4 C atoms;
- X is a polyester group.
A pigment dispersing agent comprising an amide-modified resin or amide-modified hydrocarbyl moiety, the amide-modified resin or amide-modified hydrocarbyl moiety obtained by modifying a resin or hydrocarbyl moiety by reaction with one or more compounds of the formula:
- R-Het-ALK-NH2 wherein Met is a nitrogen-containing heterocyclic moiety, R represents at least one of H, C1-4 alkyl, or C1-4 alkoxy;
- and ALK is a branched or unbranched C1-6 alkylene group.
- wherein the resin or hydrocarbyl moiety comprises a carboxylate group or a functional derivative thereof, and wherein the resin is polyurethane, polyether, polyamide, polyester, terpene, or alkyd, and wherein the hydrocarbyl moiety is branched or unbranched C1-25 carboxyalkynylene.
A flushing agent comprising:
- an amide-modified resin or amide-modified hydrocarbyl moiety, the snide-modified resin or amide-modified hydrocarbyl moiety obtained by modifying a resin or hydrocarbyl moiety by reaction with one or more compounds of the formula:
- R-Het-ALK-NH2 wherein Het is a nitrogen-containing heterocyclic moiety;
- R represents at least one of H, C1-4 alkyl, or C1-4 alkoxy;
- and ALK is a branched or unbranched C1-6 alkylene group;
- and an ink solvent,
- wherein the resin or hydrocarbyl moiety comprises a carboxylate group or a functional derivative thereof thereof, and wherein the resin is polyurethane, polyether, polyamide, polyester, terpene, or alkyd, and wherein the hydrocarbyl moiety is branched or unbranched C1-25 carboxyalkynylene.
