Disclosed are methods of processing kaolin to produce ultrafine hydrous kaolin. The methods involve processing gray crude kaolin by subjecting the kaolin crude to flotation and then centrifuging the kaolin to provide a fine stream that is subject to refinement. Also disclosed are systems for the automated processing of gray crude kaolin to produce the ultrafine hydrous kaolin and paint compositions that contain the ultrafine hydrous kaolin.

An unsupported platy titanium dioxide pigment containing an organic dye laked thereon. The dyed TiO₂ pigment is useful to color cosmetic, food, and drug formulations.

The present invention includes a paint or coating composition comprising an organic pigment or dye complexed to the surface of a layered or fibrous inorganic clay. A wide variety of paint colors can be obtained by varying the pH during the preparation as well as by varying the synthesis conditions and changing particle size of the clay.

The invention provides a process for producing homogeneous and storage-stable pastes, inks, paints, coverings, coatings and coating materials which comprises using ionic liquids as dispersing additives.

The invention discloses a preparation method for a C.I. pigment red 53:1. The preparation method comprises the following steps of: the preparation of diazo liquid, the preparation of coupling liquid, coupling, laking reaction and post treatment. By the preparation method, the adverse effect on environment and human bodies when the component of the diazo liquid, namely 2-amino-5-chlorin-4-methyl benzene sulfonic acid is dissolved is effectively avoided; the problems that the heavy metal barium in the product exceeds the standard due to the addition of excess barium chloride in the laking reaction, and the heat resistance of the product is reduced due to the use of rosin are effectively solved; simultaneously, the pigment prepared by the method is bright in color, easy to disperse, and floppy in pigment particles; and moreover, the content of the soluble heavy metal barium in the product is below 80 mg/kg.

This invention relates to non-bleeding and controlled color-releasing speckles for use in granular laundry detergents and other consumer products. The speckles are comprised of a salt or salt-containing carrier, a coloring agent, and a water-insoluble (or minimally water-soluble) salt coating.
