Abstract:
A color photographic recording material comprising at least one photosensitive silver halide emulsion layer which is spectrally sensitized with a monomethine cyanine dye, and said monomethine dye corresponds to the formula I: ##STR7## in which: R.sup.1 is a benzothiophene radical which is coupled by way of the 2-, 3-, 4-, 5-, 6- or 7-position thereof to the benzo ring of the benzothiazole group,R.sup.2 and R.sup.3 (the same or different) and are sulphoalkyl, carboxylalkyl,--(CH.sub.2).sub.n --SO.sub.2 --NH--SO.sub.2 --NH--SO.sub.2 -alkyl, --(CH.sub.2).sub.n --SO.sub.2 --NH--CO-alkyl,and n is 1 to 6;R.sup.4 to R.sup.6 (the same or different) and are hydrogen, halogen, --CN, --CF.sub.3, alkyl, alkoxy, aryl or a heterocyclic group;or R.sup.5 together with R.sup.4 or R.sup.6 forms an optionally substituted benzene ring; andM is a cation necessary to balance the charge.
