| titleOfInvention | The preparation method of flat particle silver emulsion |
| abstract | The invention discloses a kind of preparation methods of flat particle silver emulsion.The present invention has prepared Tabular (flat) particle (abbreviation T- particle) emulsion of high row state ratio using twin columns emulsification with the method that two steps are nucleated, the form ratio of emulsion grain reaches 20 or more, and under the premise of appropriate scumbling, the maximal density of film is set to reach 3.5 or more (single side, silver content 5.0g/m by certain chemical sensitization 2 Left and right).The present invention has saved the usage amount of silver under the premise of meeting market and needing.The shape of crystal compared with the existing technology for it is more regular, the uniformity coefficient of crystal improves. |
