Self-dispersing pigments

The disclosure provides self-dispersing pigment having an isoelectric point of at least about 8 comprising an inorganic particle, and in particular a titanium dioxide (TiO.sub.2) pigment, treated sequentially by: hydrolyzing an aluminum compound or basic aluminate to deposit a hydrous alumina surface; and adding a dual-functional compound comprising 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. These self-dispersing pigments are useful in making dcor paper that may be used in paper laminates.

FORMATION OF HIGH QUALITY TITANIA, ALUMINA AND OTHER METAL OXIDE TEMPLATED MATERIALS THROUGH COASSEMBLY

A co-assembly method for synthesizing inverse photonic structures is described. The method includes combining an onium compound with a sol-gel precursor to form metal oxide (MO) nanocrystals, where each MO nanocrystal has crystalline and amorphous content. The MO nanocrystals are combined with templating particles to form a suspension. A solvent is evaporated from the suspension to form an intermediate or compound product, which then undergoes calcination to produce an inverse structure.
