The present invention relates to a dispersant derived from an alcohol terminated polymer and via an anhydride intermediate. The anhydride functionalized polyester is then reacted with a multi-amine species forming amide and salt bonds.

Multi-amine polyester dispersant made via an anhydride intermediate

The present invention relates to a dispersant derived from anhydride functionalized polyester derived from carboxylic acid functionalized polyester. The anhydride functionalized polyester is then reacted with a multi-amine species forming amide and salt bonds. The technology allows lower reaction temperatures when the multi-amine species is present. The lower reaction temperature allows the use of a broader selection of polyester repeat units.

Multi-amine dispersant made via an anhydride intermediate

The invention provides dispersed inorganic mixed metal oxide pigment compositions in a hydrocarbon media utilizing a dispersant having polyisobutylene succinic anhydride structure reacted with a non-polymeric amino ether/alcohol to disperse a mixed metal oxide pigment in the media. The metal oxide pigment is of the type used to color ceramic or glass articles. A milling process using beads is also described to reduce the mixed metal oxide particle size to the desired range. A method of using the mixed metal oxide dispersion to digitally print an image on a ceramic or glass article using the dispersion jetted through a nozzle and subsequently firing the colored article is also described.

Aliphatic ceramics dispersant

Polymeric dispersants are disclosed that include an acrylic backbone at least one pendantly attached imide group, wherein the carbonyl of the imide are chemically bonded to a fused aromatic ring. The aromatic ring can be substituted with various electron withdrawing or releasing groups. Desirably dispersant also includes solvent-solubilising chains of polyether, polyester, polyacrylate, and or polyolefin.

Acrylic dispersants with fused aromatic imide anchor groups

The present invention relates to a dispersant having a tertiary or quaternary amine anchoring group and a solubilizing polymer selected from Cfatty acid; a Cak(en)yl substituted succinic acid, anhydride or partial ester; a dimer or trimer fatty acid; and/or polymers from repeating units of polyesters, polyethers, polyacrylate, polyamides, polyurethanes or mixtures of said repeating units in a random or blocky copolymer. The dispersants are an improvement in that the alkylene connecting group between the tertiary or quaternized amine and the solubilizing polymer lacks abstractable hydrogen atoms at the geminal carbon atom from the nitrogen of the tertiary or quaternized amine over the prior art. The dispersants are useful as dispersants with improved thermal stability and low amounts yellow color after aging at elevated temperatures.

Polymeric dispersants containing one or two quaternary amine anchoring groups with improved chemical and thermal stability

The invention provides dispersed inorganic mixed metal oxide pigment compositions in a non-aqueous media utilizing a dispersant having polyisobutylene succinic anhydride structure to disperse a mixed metal oxide pigment in the media. The metal oxide pigment is of the type used to colour ceramic or glass articles. A milling process using beads is also described to reduce the mixed metal oxide particle size to the desired range. A method of using the mixed metal oxide dispersion to digitally print an image on a ceramic or glass article using the dispersion jetted through a nozzle and subsequently firing the coloured article is also described.

Dispersants for colouration of ceramic tiles using ink jet inks

The invention provides dispersed inorganic mixed metal oxide pigment compositions in a non-aqueous media utilizing a polyester dispersant having a terminal hydroxyl, tertiary amine or quaternized amine anchoring group and a mixed metal oxide pigment. The metal oxide pigment is of the type used to colour ceramic or glass articles. A milling process using beads is also described to reduce the mixed metal oxide particle size to the desired range. A method of using the mixed metal oxide dispersion to digitally print an image on a ceramic or glass article using the dispersion jetted through a nozzle and firing the coloured article is also described.

Polyester dispersants for colouration of ceramic tiles using ink jet inks and ink jet ink printers

A polyurethane dispersant is described that comprises a reaction product of a polyisocyanate with a) a component supplying a anchoring imide group wherein the carbonyl groups of the imide are bonded to a fused or non-fused aromatic ring, b) at least one solvent-solubilizing chain, and other optional components to build molecular weight or modify the interaction of the dispersant with various particulates or continuous media.

Dispersants with multiple aromatic imide anchor groups

The invention provides dispersed inorganic mixed metal oxide pigment compositions in a non-aqueous media utilizing a dispersant having terminal end groups and a central portion of the structure &#x2014;[CH(A)-C(B)(D)]n-[CRCR]m- to disperse a mixed metal oxide pigment in the media. The metal oxide pigment is of the type used to color ceramic or glass articles. A milling process using beads is also described to reduce the mixed metal oxide particle size to the desired range. A method of using the mixed metal oxide dispersion to digitally print an image on a ceramic or glass article using the dispersion jetted through a nozzle and subsequently firing the colored article is also described.

Modified polyacrylate dispersants for the decorative ceramic market

Polymeric dispersants are disclosed that include a urethane backbone at least one pendantly attached imide group, wherein the carbonyl of the imide are chemically bonded to a single or fused aromatic ring. The aromatic ring can be substituted with various electron withdrawing or releasing groups. The dispersant also includes solvent-solubilizing chains of polyether, polyester, polyacrylate, and or polyolefin Desirably, the imide groups are derived from an imide that has two isocyanate reactive groups such that the imide is attached to the urethane backbone at two separate locations.

The present invention relates to an additive to prevent phase separation between a low profile additive and the other components of the molding composition, said other components comprising at least an unsaturated resin and an unsaturated monomer.
