Method for dispersing droplet type emulsified material within liquid feeding system and coating method using the dispersing method

摘要

A dispersing method carried out in a liquid feeding system includes passing a dispersing medium containing an oil droplet type emulsified material at a flow rate of not less than 5 cc/cm2.min through a filter with a plurality of pores having such a size as to permit an oil droplet type emulsified material having a predetermined particle diameter to pass therethrough to reduce the size of the coarse particles of the oil droplet type emulsified material to below a predetermined particle diameter. The dispersing method is particularly suitable for use in the production of photographic layers.
