Abstract: An anti-reflection film has a low refractive index layer and a high refractive index layer. The low refractive index layer is formed by coating a composition comprising (a) a hydrolysis product or a partial condensation product of an organosilane and (c) a vinyl resin. The organosilane is represented by the formula of R.sup.1 Si(OR.sup.2).sub.3 in which R.sup.1 is an alkyl group having 1 to 10 carbon atoms, an alkenyl group having 2 to 10 carbon atoms or an aryl group having 6 to 10 carbon atoms, and R.sup.2 is an alkyl group having 1 to 5 carbon atoms or an acyl group having 1 to 4 carbon atoms. The vinyl resin has at least one silyl group substituted with a hydrolyzable group or hydroxyl.

Abstract: A silver halide photographic material comprises a plastic support, a silver halide emulsion layer and an antistatic backing layer. A process for the preparation of the photographic material comprises the steps of: coating a silver halide emulsion on one side of the support to form the silver halide emulsion layer; and coating an aqueous coating solution on the other side of the support to form the antistatic backing layer. The coating solution contains electroconductive particles, a binder and a specific nonionic surface active agent represented by the formula (Ia), (Ib), (II), (III) or (IV).
