    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: 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: Dispersions containing a liquid vehicle (which can be aqueous, semi-aqueous or non-aqueous), organic or inorganic particles (or mixtures) that are insoluble in the liquid vehicle and a polymeric dispersant, preferably a structured polymeric dispersant, having one or more segments soluble in the liquid vehicle and one or more segments insoluble in the liquid vehicle, have improved stability when the insoluble segment(s) contains cross-linking groups which are cross-linked to itself or a cross-linking compound such as a polyfunctional monomer, oligomer or polymer to form an encapsulation network that entraps the particles which are particularly useful for paints or inks in coating and printing applications.
