<p>Photographic processing compositions, such as developing compositions, fixing compositions, bleacning compositions, bleach-fixing compositions, stabilizing compositions, and the like, are prepared in the form of a stable paste that is adapted to be diluted with water or other liquid medium to form a working processing solution. The paste composition utilizes the association of finely-divided solid particles in a stable three-dimensional network to provide advantageous characteristics of both a physical and chemical nature. It provides major economic advantages as compared to liquid concentrates with regard to packaging, transporting, and storage considerations and, in view of the convenience in handling and the ease with which it can be converted to a working solution, is substantially superior to a dry powder mix.</p> |
