在水彩正胶片的生产过程中,发现使用少量氯化银乳剂,能显著的提高水彩正黄层的感光度。其效果随氯化银乳剂用量增加而增加。达到某一值后感光度就不再增加。在感光度提高的过程中有时会在黄层有大晶片析出。如图所示。用于这种大晶片的析出,使黄层斑斑点点,严重的影响银幕的效果。为了观察和研究大晶片。我们应用上海新跃厂生产的DxA。4—10型透射电镜对产生大晶片的过程进行了广泛的研究。为提高水彩正胶片质量提供了最直观,最可靠的依据。
In the production of watercolor positive film, found that the use of a small amount of silver chloride emulsion, can significantly improve the sensitivity of the watercolor is yellow. The effect of silver chloride emulsion dosage increases. After reaching a certain value, the sensitivity will no longer increase. In the process of increasing the sensitivity sometimes in the yellow layer of large wafer precipitation. as the picture shows. For the precipitation of such a large wafer, the yellow layer spots, a serious impact on the screen effect. In order to observe and study large wafers. We use DxA produced by Shanghai Xin Yue Chang. 4-10 type of transmission electron microscopy to produce a large chip process has been extensively studied. To improve the quality of watercolor film provides the most intuitive and most reliable basis.
