Abstract: Color photographic images having advantageous sensitometric properties, in particular high maximum magenta color density, can be obtained by use of a color photographic recording material containing a pyrazoloazole type magenta coupler of formula IQ--L--COOH IIn the formulaQ denotes the bicyclic group capable of color coupling in a pyrazolo[3,2-c]-1,2,4-triazole magenta coupler andL denotes a linking member which is not split off in the color coupling reaction and which cointains a ballast residue unless a ballast residue which cannot be split off is attached to the non-coupling ring of the bicyclic group Q.

Abstract: For electronic image recording in one or more colors a photographic recording material comprising in at least one layer photo-sensitive silver halide and a compound capable of luminescence is image-wise exposed and developed to produce a latent luminescence image. The image information contained in the latent luminescence image is scanned photoselectively by a luminescence spectroscopic process and is recoded electronically in the form of monochromatic luminescence signals. The process provides images in one or more colors and is highly sensitive. Recording materials of extremely low silver application can be used.

Abstract: The invention relates to a process for luminescence-spectroscopic examination and determination of coatings and coating profiles of solid and liquid layers and layer assembles whereby the luminescent substances present in the layers are photoselectively probed and determined through emission product spectra in incident and/or transmitted light by a photon detector using an emission spectroscopic process and whereby the photoselectivity of the luminescence-spectroscopic process being based on the substance related choice of the difference in wavelength .DELTA. .lambda. between the emission wavelength .lambda..sub.e and the excitation wavelength .lambda..sub.a.
