Color photographic recording material
摘要:
A color photographic recording material contains at least one silver halide emulsion layer which is spectrally sensitized with a monomethinecyanine dye of the following general formula I in whichR.sup.1, R.sup.2, R.sup.3, R.sup.4 and R.sup.5 (identical or different) mean: H, halogen, alkyl, methoxy, aryl, 1-pyrrolyl, 2-pyrrolyl, 3-pyrrolyl, 2-furanyl, 2-thienyl, 3-thienyl, 1-indolyl, N-carbazolyl or N-isoindolyl, or R.sup.4, together with R.sup.3 or R.sup.5, means the residue necessary to complete an optionally substituted fused benzene ring or R.sup.4, together with R.sup.3, means the residue necessary to complete an optionally substituted fused naphthalene ring system;R.sup.6 and R.sup.7 (identical or different) mean: alkyl, sulphoalkyl, carboxyalkyl, --(CH.sub.2).sub.n --SO.sub.2 --NH--SO.sub.2 -alkyl, --(CH.sub.2 ).sub.n --SO.sub.2 --NH--CO-alkyl, --(CH.sub.2).sub.n --CO--NH--SO.sub.2 -alkyl, --(CH.sub.2).sub.n --CO--NH--CO-alkyl (n=1-6);X means --O--, --S--, --Se--, --NR.sup.8 --(R.sup.8 =optionally substituted alkyl);a means H, an aromatic residue or, together with b, the residue necessary to complete a fused benzene ring;b either together with a or together with c, means the residue necessary to complete a fused benzene ring;c means H, an aromatic residue or, together with b or d, the residue necessary to complete a fused benzene ring;d means H, an aromatic residue or, together with c, the residue necessary to complete a fused benzene ring;A means an optionally present anion.The recording material exhibits increased blue sensitivity.
