Abstract
A method of color image formation is disclosed, comprising imagewise exposing a color photographic light-sensitive material comprising a reflective support having provided thereon at least one light-sensitive layer containing a color coupler capable of forming a color image upon coupling with an oxidation product of an aromatic primary amine developing agent and a silver halide emulsion, and processing the exposed light-sensitive material with a color developing solution containing substantially no benzyl alcohol within a development time of 2 minutes and 30 seconds, wherein said processing is carried out in the pressence of at least one compound represented by formula ##STR1## wherein R.sup.1, R.sup.2, R.sup.3, and R.sup.4 each represents a hydrogen atom, a hydroxyl group, a substituted or unsubstituted alkyl group, a substituted or unsubstituted alkenyl group, a substituted or unsubstituted alkynyl group, an acyl group, or a sulfonyl group; or R.sup.1 and R.sup.2, or R.sup.3 and R.sup.4 together form a ring; X represents a substituted or unsubstituted lower alkylene group; and n represents an integer of from 1 to 4. Disadvantages due to use of benzyl alcohol can be eliminated, and reduction in color density noted when color development processing is conducted over a short time without using benzyl alcohol can be prevented.
