ABSTRACT:
A silver halide color photographic material comprising a support having thereon at least one light-sensitive silver halide emulsion layer, wherein the silver halide emulsion layer contains a silver halide emulsion sensitized by a methine dye represented by following formula (I) and the total content of calcium in the photographic constituting layers on the support is not more than 10 mg/m.sup.2 ; ##STR1## wherein Q represents a non-metallic atomic group necessary for forming a 5-membered or 6-membered ring; R.sub.1 to R.sub.11 each represents a hydrogen atom or a substituent, however, at least one of R.sub.1 to R.sub.3 represents a group containing an aromatic group and R.sub.4 and R.sub.5 are not a hydrogen atom; L.sub.1 to L.sub.3 each represents a methine group; n represents an integer of from 0 to 6; M represents a counter ion neutralizing an electrostatic charge; and m represents 0 or 1;
The material provides an excellent stability showing less deviation of the performance at the production thereof and provides an excellent processing stability and less depositions in processing liquids and thus forms less streaks even in continuous processing.
