Abstract: Dyes are described corresponding to the following formula for use as light-absorbing dyes in silver halide photographic material: ##STR1## wherein: Z represents the atoms necessary to form a barbituric acid nucleus (p=1 or 2), a phenyl group (p=0 or 1) or a pyrrole ring (p=0)Each of L.sup.1, L.sup.2 and L.sup.3 represents a methine group,R.sup.3 represents an aliphatic or aromatic hydrocarbon group,R.sup.1 represents hydrogen, alkyl, acyl or amino andR.sup.2 represents hydrogen, alkyl or aryl, or R.sup.1 together with R.sup.2 represents the atoms necessary to complete a heterocycle.

Abstract: A direct-positive photographic element is described which comprises a support and a spectrally-sensitized light-sensitive silver halide emulsion layer containing fogged silver halide grains wherein the said emulsion is spectrally sensitized by means of a dye containing a pyrrolo[ 2,1-b]thiazole nucleus which may be substituted and carry one or more fused-on rings, the said nucleus being linked by the 5- or 7-carbon atom thereof, directly or through a dimethine chain to another nitrogen containing heterocycle.
