Method and apparatus for preparing grains of silver salt of organic acid and method for producing thermally processed image recording material

摘要

Disclosed are a method for preparing grains of silver salt of an organic acid by reacting a solution containing silver ions and a solution containing an alkali metal salt of an organic acid, in which the reaction is performed in sealed mixing means and which comprises steps of supplying the solution containing silver ions into a reaction field solution before introduced into the sealed mixing means, and supplying the solution containing an alkali metal salt of an organic acid into the reaction field solution or sealed mixing means to which the solution containing silver ions has been supplied, etc. According to the present invention, high quality grains of silver salt of an organic acid can be efficiently produced at low cost.
