Abstract
The present invention allows one to use a phase I reactor to make thinner silver halide grains. This is accomplished by introducing the halide salt solution and the silver salt solution as close as possible to each other above the mixer head. The reactor is essentially divided into a micro reaction zone and a bulk reaction zone, thus, emulating the effect of a phase II or two stage reactor.
