Process for the preparation of color-photographic sensitive materials using nonionic and anionic surface active agents
Abstract
Abstract A PROCESS FOR PRODUCING COLOR-PHOTOGRAPHIC SENSITIVE MATERIAL COMPRISING A SUPPORT AND A SILVER HALIDE EMULSION CARRIED THEREON. THE EMULSION CONTAINS A FINELY DISPERSED COLOR-FORMING COUPLER WHICH HAS A HYDROPHOBIC RADICAL CONTAINING 9-28 CARBON ATOMS. THE COLOR-PHOTOGRAPHIC MATERIL IS FORMED BY DISPERSING THE ABOVE COUPLER IN AN AQUEOUS GELATIN SOLUTION IN THE PRESENCE OF A NONIONIC SURFACE ACTIVE AGENT OBTAINED BY THE ESTERIFICATION OF ONE TO TWO HYDROXYL GROUPS IN AN ANHYDROHEXITOL MOLECULE WITH A FATTY ACID CONTAINING 10 TO 20 CARBON ATOMS AND AN ANIONIC SURFACE ACTIVE AGENT CONTAINING BOTH A HYDROPHOBIC RADICAL CONTAINING 8 TO 30 CARBON ATOMS AND A WATER-SOLUBILIZING MO3S-OR MO3SO-GROUP WHEREIN M REPRESENTS A HYDROGEN ATOM, OR AN ALKALI METAL ATOM OR AN AMMONIUM GROUP.
