ABSTRACT:
In order to maintain product quality control and process control when producing photographic materials, it is necessary to measure droplet size of dispersions or dispersion melts utilized to produce such materials. Known methods of measuring the droplet size require off-line techniques and there is no readily available process control. Described herein is an on-line technique for the measuring of droplet size which provides such process control.
