    摘要： A process is described for the production of high yields of lead chromate-containing pigments in a nondusting granular form. The process involves agitating in aqueous medium designated amounts of a lead chromate-containing pigment, a friable, low molecular weight hydrocarbon-type resin softening at 50.degree.-95.degree. C. and a cationic surfactant at a temperature above the softening point of the resin and continuing agitation at a temperature within the range of about 5.degree. to about 20.degree. C. above the softening point of the resin until the pigment dispersion is granulated. The process provides yields of at least 70% of granules in the particle size range of about 0.1 to about 4 millimeters. The granules are particularly useful as colorants for air-drying enamel coating systems and plastics.

    摘要： An improved method for encapsulating water-insoluble particles, particularly pigments, with dense, amorphous aluminum phosphate or fluorophosphate is disclosed. The capsules are formed in situ in an aqueous dispersion of the substrate by complexing aluminum and/or magnesium ion with phosphoric or fluorophosphoric acid, preferably in the presence of either boric acid or fluoride or complex fluoro ions. The encapsulation method comprises continuously adding separate solutions of the reactants into the dispersion over a 0.5 to 5.0 hour period, at 70.degree. to 100.degree. C., whereby a complex phosphate or fluorophosphate is deposited around the particles in the form of continuous, adherent microcapsules. The chemical, thermal and light stability of the substrate is thereby improved.
