    • Disclosed is a silver halide photographic material which comprises a monodispersed polymer having an average grain size of from 1 to 10 .mu.m and variation coefficient of 0.10 or less and having a functional group which forms a covalent bond by reacting with an organic hardening agent or gelatin. Preferably, the polymer is a polymer obtained by polymerization by adding to a hydrophilic organic solution a high molecular weight dispersant which is dissolved in the hydrophilic organic solution and further adding at least one vinyl monomer which is dissolved in the hydrophilic organic solution but the polymer to be formed is precipitated from the hydrophilic organic solution. More preferably, the polymer contains 60 wt % or more of the repeating unit derived from methyl methacrylate and has a glass transition point of 60.degree. C. or more. The silver halide photographic material is excellent in antistatic property, transporting property, adhesion resistance, transparency, scratch resistance, graininess, drying property and mat pinholes.
    • 公开了一种卤化银照相材料,其包含平均粒度为1-10μm的单分散聚合物和0.10或更小的变异系数,并且具有通过与有机硬化剂或明胶反应形成共价键的官能团 。 优选地,聚合物是通过向亲水性有机溶液中加入溶解在亲水性有机溶液中的高分子量分散剂并进一步加入至少一种溶解在亲水性有机溶液而是聚合物中的乙烯基单体而聚合而获得的聚合物, 形成从亲水性有机溶液中沉淀出来。 更优选地,聚合物含有60重量%以上的衍生自甲基丙烯酸甲酯的重复单元,玻璃化转变点为60℃以上。 卤化银感光材料的抗静电性,输送性,耐粘附性,透明性,耐擦伤性,颗粒性,干燥性和垫针孔性优异。
