ABSTRACT:
A process for improving the method by which a powder such as a dye is added to a gelatino silver halide element is described. This process involves encapsulating the powder within a gelatin capsule. This process avoids cross-contamination and dusting when powder is added to solvent and also reduces the use of extra solvent in the manufacture of the element.
