Abstract
The reduction in cyan coloring density of a color photographic paper caused by the conversion of cyan dye into leuco compound during blixing is prevented by reducing the total amount of silver contained in the silver halide emulsion layer or layers disposed between the cyan coloring silver halide emulsion layer and the support of the color photographic paper. The total amounts of silver in these layers should be 0.6 g/m.sup.2 or less. When the silver content is reduced in order to prevent a reduction in cyan color density, it is generally desirable to utilize only particular magenta couplers in order to avoid reducing the magenta color density.
