Abstract: A photographic assemblage comprising a silver halide photographic light-sensitive element comprising at least one sulfur and gold sensitized silver halide emulsion layer, said element comprising chlorinated s-triazine hardeners and photographically useful chemical compounds containing cyano groups, and a closed vessel in which the element is closed and stored at a constant relative humidity, is protected against HCN gas, which may evolve from photographic addenda included in the light-sensitive element to cause fog in the silver halide emulsion layers, by the addition of a palladium compound, in a silver halide emulsion layer and/or an adjacent layer thereto, as scavenger for HCN gas released from the element.

Abstract: The present invention relates to a silver halide photographic material comprising a support having coated thereon at least one silver halide emulsion layer and at least one light-insensitive hydrophilic colloid layer wherein at least one of said layers comprises a gelatin hardening agent and said hydrophilic colloid layer comprises an alkali-insoluble acrylic polymer particles having an average particle size of from 0.5 to 6 .mu.m and wherein at least 95% by number of said polymer particles have a particle size within .+-.15% of the average particle size.

Abstract: A process for preparing bisphenol fluorene products which comprises reacting fluorenone with a phenol compound in the presence of an acidic condensing agent in a solution of an organic liquid wherein the bisphenol fluorene compound is insoluble and recovering the obtained bisphenol fluorene product from the reaction mixture.
