Abstract
This invention relates generally to dye-attached and/or surface-modified (e.g. functionalized) pigments. Certain embodiments include pigments formed by attaching a dye to the surface of a metal oxide or semi-metal oxide particle. Other embodiments include surface-modified pigments formed by attaching polymers having amine groups to the surface of a pigment. The surface functionalization of pigment particles with polymers having amine groups may provide the pigment with enhanced water resistance, color-fastness, smudge resistance, and/or compatibility with other materials in a composite or matrix material(s). For example, such functionalized pigments may be used in inks, paints, paper, fabrics, coatings, cosmetics, food, or other composites to provide or adjust hydrophobicity, softness, smoothness, and/or oleophobicity.
