Method for precipitating separation of photosensitive silver halide particle dispersion and silver salt photothermographic dry imaging material using thereof
A method for separating photosensitive silver halide particles by precipitation from a dispersion comprising the silver halide particles and a protective colloid of a natural polymer, the method comprising the step of mixing the dispersion with an organic polymer having a logarithm value of n-octanol/water partition coefficient (being a log P value) of 0.8 to 2.0 so as to separate the silver halide particles from the dispersion.
