Process for preparing self-dispersing pigments
The disclosure provides a process for preparing a self-dispersing pigment having an isoelectric point of at least about 8 comprising: (a) adding a dual functional compound with an acidic aluminum salt to form an aqueous solution, wherein the dual functional compound comprises an anchoring group that attaches the dual-functional compound to the pigment surface, and a basic amine group comprising a primary, secondary or tertiary amine; (b) adding a base to the mixture from step (a) whereby the pH is raised to about 4 to about 9 to form a turbid solution; and (c) adding the mixture from step (b) to a slurry of inorganic particles whereby a hydrous alumina and the dual functional compound are deposited on the pigment surface. The self-dispersing pigments prepared by this process are useful in making dcor paper that may be used in paper laminates.
SILANE-TREATED FORSTERITE FINE PARTICLES AND PRODUCTION METHOD THEREFOR, AND ORGANIC SOLVENT DISPERSION OF SILANE-TREATED FORSTERITE FINE PARTICLES AND PRODUCTION METHOD THEREFOR
The invention provides silane-treated forsterite microparticles having a specific surface area of 5 to 100 m.sup.2/g, wherein 1 to 5 silyl groups are bound to 1 nm.sup.2 of the surface area thereof.
Treated fillers, compositions containing same, and articles prepared therefrom
The present invention includes a process for producing treated filler that includes (a) treating a slurry that includes untreated filler where the untreated filler has not been previously dried, with a treating composition that includes a treating agent, thereby forming a treated filler slurry, and (b) drying the treated filler slurry to produce treated filler. The treating agent can include a polymer having (i) at least one first group that interacts with the untreated filler and (ii) at least one second group that interacts with a rubber matrix into which the treated filler is incorporated. The present invention also is directed to treated filler prepared by the process, as well as rubber compounding compositions and tires including the treated filler.
