Dispersions, films, coatings and compositions
First Claim
1. A non-aqueous dispersion comprising an organic solvent comprising at least 50 wt % of said dispersion and a solids component which comprises not more than 20 wt % of said dispersion, said solids component comprising fine particles and an organically-modified layered inorganic species capable of being dispersed by said solvent and, optionally, an organic polymeric species and/or a reactive precursor of an organic polymeric species soluble in said solvent, said polymeric species and/or reactive precursor of a polymeric species when present comprising less than 50 wt % of said solids content.

Abstract
A method of providing location dependent content to an end station using a base station. The base station receives from an end station and via a communications network, a content request, and an identifier indicative of an identity of the end station. The base station then authenticates the user or the end station using the identifier. In response to a successful authentication, the base station determines the location of the end station and determines content using the location or the content request, which is then transferred to the end station.

- 41. A structure comprising fine particles and an organically-modified layered inorganic species and, optionally, an organic polymeric component which, when present, comprises less than 50 wt % of the combined total weight of the particles and the species.
- 47. A structure comprising fine particles which are high aspect ratio particles and an organically-modified layered inorganic species and, optionally, an organic polymeric component which, when present, comprises less than 50 wt % of the combined total weight of the particles and the species, wherein the fine particles are at least partially oriented.
- 72. A structure comprising electrically-conductive fine particles and an organically-modified layered inorganic species and an organic polymeric component which comprises at least 50 wt % of the total weight of the structure, wherein said structure has an electrical percolation threshold lower than and/or a transparency greater than an equivalent structure in which the organically-modified layered inorganic species is absent.
