Gelatin-grafted-polymer particles as peptizer for silver halide emulsions |
摘要 |
This invention describes the use of gelatin-grafted-polymer particles as peptizers for the preparation of silver halide photographic emulsions, whereby the gelatin-grafted-polymer particles remain attached to the AgX crystals after preparation of the emulsions. In an embodiment of this invention, the core polymer particles are loaded with photographically useful agents. When the photographic agent is a dye-forming coupler, multicolor mixed-packet systems can be constructed using the packet emulsions prepared in the manner of this invention.
