Abstract: 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 (TiO2) 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 décor paper that may be used in paper laminates.

Abstract: The present invention comprises a composition and method of use for providing durable dirt pickup resistance to architectural coatings. Such compositions comprise a coating base and a post-modified crosslinkable fluoropolymer additive, such that the coatings additive is allowed to migrate to the coating surface and further cure once applied to a substrate. The compositions of the present invention provide durability to coating compositions, while also providing surface effects such as increased water and oil contact angles, enhanced dirt pickup resistance, and enhanced cleanability to the coating films.

Abstract: The disclosure describes a process for making a décor paper from a dispersion with improved optical performance by (a) combining a treated TiO2 particle having a surface area of at least about 30 m2/g with water and a cationic polymer to form a TiO2 particle slurry; wherein the treated TiO2 particle comprises an oxide selected from the group consisting of silicon, aluminum, phosphorus and mixtures thereof; and the oxide is present in the amount of at least 15% based on the total weight of the treated titanium dioxide particle; (b) combining the TiO2 particle slurry of step (a) with paper pulp and a cationic polymer. The dispersion provides equal optical performance using less TiO2 when compared to the same dispersion not comprising the TiO2 particle slurry of (a). These décor papers are useful in preparing paper laminates.
