Abstract

See full text

A ready-to-use photographic color developing composition for the development of high bromide silver halide photographic element, said composition being substantially free of bromides, hydroxylamines and benzyl alcohol and comprising a color developing agent, a buffering agent, a complexing agent, an antifogging agent, a contrast promoting agent, an antioxidant agent and a polyol compound. A rapid access processing method of a high bromide silver halide photographic color element, said method comprising the steps of: developing said element for a period of about 75 to about 105 seconds in a ready-to-use color developing composition substantially free of bromides, hydroxylamines and benzylalcohol and comprising a color developing agent, a buffering agent, a complexing agent, an antifogging agent, a contrast promoting agent, an antioxidant agent and a compound of formula: R--(OH).sub.n wherein R is a straight or branched or alycyclic alkyle with 4 to 8 carbon atoms and n is an integer from 4 to 8, and containing said antioxidant agent in a quantity equal to or lower than 0.01 moles per liter with a developing agent to antioxidant agent molar ratio higher than or equal to 2:1, washing said element for a period of about 10 to about 20 seconds, bleach-fixing said element for a period of about 75 to about 105 seconds in a ready-to-use bleach and fix composition having a pH value in the range from 5 to 8 and having a bleaching agent to antioxidizing agent weight ratio equal to or lower than 20:1, and stabilizing said element, without washing between the bleach-fixing and stabilizing step, for a period of about 45 to about 75 seconds.
