    摘要: The invention relates to a photographic recording material comprising a layer support and, arranged thereon, at least one photosensitive silver halide emulsion layer which contains an antifogging agent corresponding to formula (I) ##STR1## in which A, R.sub.1 and R.sub.2 are as defined in the specification. The antifogging agents according to the invention reduce fogging without significantly affecting gradation and improve the staility of the photographic material in storage.

    摘要: In a process for preventing the contact spots formed by contact of the back coating of photographic material with the emulsion side an aqueous polymer dispersion obtained by polymerization of halogen-free compounds and polyvinyl alcohol or partially acetylated polyvinyl alcohol in the presence of an anionic emulsifier are added to the casting composition applied as outermost back coating and/or as uppermost layer.
