An anticorrosive pigment comprising an aluminum polyphosphate comprises at least one cerium-based compound and/or one lanthanum-based compound and/or one praseodymium-based compound. An anticorrosive paint incorporating the pigment is also provided.

This invention relates to non-bleeding, non-staining occult particles for use in granular or powdered laundry care compositions such as laundry detergents, laundry aids, and fabric care compositions. The occult particles are comprised of a clay carrier and a coloring agent and are characterized as being substantially indiscernible when contained in the laundry care composition.

In various embodiments, the present invention is directed to a facile one-pot reverse emulsion process to assemble core-shell nanoparticles (CS-SMNPs) into bright and noniridescent photonic supraballs. In one or more embodiments, the present invention is directed to core-shell nanoparticles having an inner high refractive index (RI) core and an outer low RI shell. In one or more embodiment, the present invention includes core-shell nanoparticles using high RI (1.74) melanin cores and low-RI (1.45) silica shells. In various embodiments, these nanoparticles may be self-assembled into bright and noniridescent supraballs using a scalable one-pot reverse emulsion process. According to various embodiments of the present invention, it is possible to generate a full spectrum of structural colors with the combination of only two ingredients, synthetic melanin and silica.

The invention seeks protection for a novel method for the surface functionalization of solid materials with one or more active ingredients intended to confer specific properties thereon, such as anti-UV, fluorescence or coloring properties.

Provided in one example herein is a liquid electrophotographic ink composition. The composition comprises: a carrier fluid comprising a polymer; ink particles each comprising a non-aqueous polymeric resin and pigment particles distributed in the polymeric resin; and a charge director. The pigment particles comprise a metal oxide and have a hydrophobic surface. The hydrophobic surface comprises at least one of the following: (i) nanoparticles attached to each of the pigment particles, the nanoparticles comprising at least one of an oxide, a phosphate, and a nitrate; (ii) a coating disposed over each of the pigment particles, the coating comprising at least one of an oxide, a phosphate, and a nitrate; and (iii) a coating disposed over each of the pigment particles, the coating comprising at least one of a polymer and an oligomer.

The present invention addresses the problem of providing: a pigment dispersion liquid with which an optical filter layer having the functions of both a color filter and a near-infrared cut filter can be formed by performing a development step once, and with which a thin filter achieved by using a single-layer configuration instead of a conventional two-layer configuration can be fabricated; and a colored resin composition containing the pigment dispersion liquid. The present invention provides a pigment dispersion liquid containing one or more organic color pigments selected from the group consisting of pigment red, pigment green, pigment blue, pigment yellow, and pigment violet, an infrared absorbing dye having a maximum absorption wavelength in a wavelength range of 750-2000 nm, and an oil-soluble organic solvent or an aqueous medium, and a colored resin composition containing the dispersion liquid.

Provided is a black pigment that enables pattern formation of pixel division layer while suppressing generation of development residue. The black pigment comprises (a) a core containing at least one organic black pigment selected from the group consisting of benzodifuranone-based black pigments, perylene-based black pigments, azo-based black pigments, and isomers thereof and (b) a coating layer containing silica and/or a metal oxide and/or a metal hydroxide.
