本文介绍一种制备卤化银颗粒的新方法,即在乳剂中补加卤化银,使其沉积在原有颗粒上。凡补加卤化银所生成的颗粒与原有颗粒在性质上不同的乳剂,一般称为核/壳乳剂或包壳乳剂。核/壳乳剂颗粒,系在胶粘剂存在下,由可溶性银盐与一种或数种卤盐反应 This article describes a new method for preparing silver halide grains by adding silver halide to the emulsion to deposit on the original grains. Where additional silver halide particles generated by the nature of the original particles of the emulsion, commonly known as the core / shell emulsion or emulsion. Core / shell emulsion particles, in the presence of an adhesive, are reacted with one or more halide salts from a soluble silver salt
