Decor paper comprising self-dispersing pigments

摘要

Disclosed is a décor paper with a self-dispersing pigment having an isoelectric point of at least about 8, where the inorganic particle is treated sequentially by (a) hydrolyzing an aluminum compound or basic aluminate to deposit a hydrous alumina surface and (b) adding a dual-functional compound. The dual functional compound has an anchoring group that attaches to the pigment surface and a basic amine group. Typically, the inorganic particle is titanium dioxide, TiO2. These décor papers are useful in making paper laminates.
