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

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

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.

Additive to prevent phase separation of low profile additive in unsaturated thermoset polyester compositions

The invention provides dispersed inorganic mixed metal oxide pigment compositions utilizing a carboxylic acid, containing dispersant and a mixed metal oxide pigment. The metal oxide pigment is of the type used to color ceramic or glass articles. The dispersant, in addition to at least one carboxylic acid group, comprises at least one 300-3000 g/mole solubilizing chain of repeating units from hydrocarbylene or repeating units from C3 or C4 alkylene ethers or mixtures of said ethers. 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 colored article is also described.

Ink jet ink compositions

A composition comprising particulate solid, an organic medium and a dispersant comprising a polyacrylic copolymer functionalized with a polyether and reacted with an aminic polybasic species.

Multi-acid multi-base graft copolymer dispersants

A composition comprising particulate solid (typically a pigment or filler), an organic medium (typically the organic medium may be a plastics material or an organic liquid) and a polyacrylic copolymer.

Dispersant composition

A composition comprising particulate solid (typically a pigment or filler), an organic medium (typically the organic medium may be a plastics material or an organic liquid) and a polyacrylic-acid-containing copolymer.
