Abstract: A photographic two-equivalent magenta coupler represented by the following general formula (I): ##STR1## wherein (A) represents a residue of a magenta color image-forming coupler in which one of the hydrogen atoms in the coupling position is eliminated; Q represents an oxygen atom or NH group; and B represents the non-metallic atoms necessary to form a 5-membered or a 6-membered ring containing the nitrogen atom and the ##STR2## group. Color photographic light-sensitive materials containing the two-equivalent magenta coupler are also described.

Abstract: A method for improving the light fastness of a magenta color image in a silver halide color photograph which comprises incorporating into a layer containing a magenta color image, which is formed upon reaction of a magenta coupler and an oxidation product of an aromatic primary amine color developing agent, at least one light fastness improving phenolic compound and at least one synergistic light fastness improving agent selected from a sulfide or sulfoxide compound represented by the following general formula (V):x--b--y (v)wherein B represents --S-- or --SO--; X and Y, which may be the same or different, each represents --(CH.sub.2).sub.n --R.sub.1, ##STR1## or ##STR2## and R.sub.1 represents --COOR.sub.3, ##STR3## --OR.sub.6, --O--COR.sub.6, --NHSO.sub.2 R.sub.6, ##STR4## --NHCOR.sub.6, a cyano group, an aryl group or a hydroxy group; R.sub.2 represents an alkyl group of 1 to 30 carbon atoms, an aryl group, an aralkyl group, a hydroxy group, a cyano group or --COOR.sub.3 ; R.sub.3 R.sub.4, R.sub.5 and R.sub.6 each represents a hydrogen atom, an alkyl group of 1 to 30 carbon atoms, an aryl group, or an aralkyl group, with the proviso that R.sub.6 is not a hydrogen atom; and n is an integer of 1 to 4. A silver halide color photographic light-sensitive material which provides a magenta dye image having a good light fastness is also disclosed.

Abstract: An apparatus for continuously making a mixture of viscous material with solid material, which comprises a pair of spaced mixing rolls for dragging the viscous material and the solid material into a gap between the mixing rolls to permit the materials to be mixed together. A pair of removal rolls, each rotatable at a higher speed than any of the mixing rolls, are provided below the mixing rolls respectively spaced a predetermined distance from the associated mixing rolls for removing layers of the mixture sticking in part to one mixing roll and in part to the other mixing roll, off from the mixing rolls. The mixture removed from the mixing rolls by the removal rolls falls downwardly onto a packaging process wherein the mixture is packed between a pair of carrier sheets of synthetic resin material.
