A silver halide photographic light-sensitive material and a process for preparing the same are disclosed wherein an oil-soluble photographic additive and, in particular, a cyan coupler is dissolved in an epoxy compound of the formula (I): ##STR1## wherein R.sub.1, R.sub.2, R.sub.3 and R.sub.4 each represents an alkyl group or substituted alkyl group containing 1 to 40 carbon atoms, an alkoxycarbonyl group or substituted alkoxycarbonyl group containing 1 to 40 carbon atoms, or a hydrogen atom, provided that R.sub.1, R.sub.2, R.sub.3 and R.sub.4 do not represent hydrogen atoms at the same time and that the sum of the number of carbon atoms of R.sub.1, R.sub.2, R.sub.3 and R.sub.4 is 8 to 60, and R.sub.1, R.sub.2, R.sub.3 and R.sub.4 may be the same or different and may combine to form a ring; or in an epoxy compound formed by linking two compounds of said formula (I) which may be the same or different through any of R.sub.1 to R.sub.4 or the ring formed by R.sub.1 to R.sub.4.
A process for forming a photographic light-sensitive material which comprises dissolving an oil-soluble photographic additive in an epoxy compound of the formula (II):
A silver halide light-sensitive photographic material containing at least one hydrophilic colloid layer containing an emulsion prepared by dissolving an oil-soluble cyan coupler represented by the formula (III):
