This invention relates to a process for preparing conditioned organic pigments by (a) milling a mixture comprising: (1) one or more crude organic pigments; (2) at least about 0.1% by weight, relative to the organic pigment, of one or more acrylic copolymer dispersants; and (3) 0 to about 100 parts by weight, relative to the organic pigment, of a milling liquid in which the organic pigment is substantially insoluble; and (b) isolating the milled organic pigment.
摘要:
Transparent iron oxide pigment dispersions which produce waterborne coating compositions having excellent transparency and reduced haze are provided. The dispersions contain dispersed pigment, an aqueous carrier, and a mixture of water-dispersible acrylic copolymer dispersants, the mixture containing at least one acrylic copolymer dispersant having acid functional groups, at least one acrylic copolymer dispersant having phosphate functional groups, and optionally at least one acrylic copolymer dispersant having alkyl amino groups and preferably benzyl groups in the pigment anachoring segment. Such pigment dispersions are useful in forming automotive waterborne paints, particularly “metallic” automotive paints.

摘要:
The invention discloses processes for thermal transfer patterning of a nanoparticle layer and a corresponding proximate portion of a carrier layer, and optionally additional transfer layers, together onto a thermal imaging receiver. The invention is useful for dry fabrication of electronic devices. Additional embodiments of the invention include multilayer thermal imaging donors comprising in layered sequence: a base film, a carrier layer and a nanoparticle layer. The carrier layer can be a dielectric or conducting layer. When the carrier layer is a dielectric layer, the base film includes a light attenuating agent in the form of a dye or pigment.
摘要:
A polymeric dispersant for pigments based on an acrylic graft copolymer wherein the graft copolymer has a weight average molecular weight of about 5,000-100,000 and comprises a hydrophobic polymeric backbone and discrete anionic and nonionic hydrophilic side chains attached to the backbone. These graft copolymers are useful as dispersants in aqueous systems, and are particularly useful in formulating exterior water borne coatings for automobiles and trucks.

摘要:
A pigment dispersion useful for forming coating compositions containing dispersed pigment, a carrier solvent and an aminated macromonomer dispersant (binder) is disclosed. The aminated macromonomer dispersant is preferably prepared by the reaction of terminally unsaturated macromonomers synthesized by cobalt-catalyzed chain transfer free radical polymerizations of methacrylic monomers with monomeric or oligomeric amines.
