    Abstract: A photographic recording material comprising a support, at least one photosensitive, gelatine-containing silver halide emulsion layer on one side of the support and a gelatine-containing NC layer on the other side of the support, in which the NC layer contains a certain hydrophilic polymer, is distinguished by the fact that there is relatively little E.sub.a curl during drying whereas sufficient E.sub.i curl is present after drying, so that the material is not damaged during processing.

    Abstract: A photographic film unit for the production of colored transfer images contains an integral neutralization system consisting of an acid polymer layer and a retarding layer. The acid polymer layer consists of a copolymer of 5 to 50 % by weight of polymerized carboxyalkyl (meth)acrylate units together with other acid monomers and optionally nonacid monomers. A preferred carboxyalkyl (meth)acrylate is the dimeric acrylic acid. The acid polymer has high acid number and low glass transition temperature.

    Abstract: A storage medium for optical data recording comprises a dye-forming combination which on exposure to light within a first range of wavelengths reacts irreversibly to form a dye, but is substantially insensitive to light within a second range of wavelengths which is capable of energizing the dye to produce luminescence. The dye-forming combination consists of a heterocyclic compound of the formula I and of a cyclic dihalodicarbonyl compound of the formula II ##STR1## The symbols are defined in the specification. An example of formula I is benzofuran and an example of formula II is dibromomaleic anhydride.
