Abstract: Color photographic recording material having a layer support and at least one silver halide emulsion layer sensitive to blue light, in which the silver halide of the blue sensitive silver halide emulsion layer is sensitized with a blue sensitizer of the J-band type and contains at least 95 mol % of silver chloride is distinguished by high sensitivity with low fog.

Abstract: Color photographic recording material containing, on a reflective layer support, at least one blue sensitive, at least one green sensitive and at least one red sensitive layer of binder containing silver halide and optionally other light insensitive layers of binder, which binder has been hardened with an instant hardener, said recording material containing either from 100 to 900 mMol of soluble chloride and from 0 to 50 mMol of soluble bromide per mole of Ag or from 0 to 600 mMol of soluble chloride and from 5 to 50 mMol of soluble bromide per mol of Ag is distinguished by an exceptionally slight storage fog.

Abstract: Compounds corresponding to the formula: ##STR1## wherein R.sub.1 and R.sub.2 denote alkyl groups with 1 to 8 carbon atoms, an optionally substituted alkenyl group with 2 to 5 carbon atoms, an optionally substituted cycloalkyl group with 5 or 6 carbon atoms or an optionally substituted aryl group or R.sub.1 and R.sub.2 together represent the ring members required to form a 5- or 6-membered cycloalkyl or cycloalkenyl group, are suitable for use as antifoggants in photographic recording materials.
