- 2. A silver halide photographic light-sensitive material as in claim 1, wherein the coupler and the epoxy are present in the same oil droplets.
- 3. A silver halide photographic light-sensitive material as in claim 1, wherein the amount of coupler contained in a silver halide emulsion layer from which a light-sensitive layer is constructed is 0.1 to 1.0 mol.
- 4. A silver halide photographic light-sensitive material as in claim 3, wherein the amount of coupler contained in a silver halide emulsion layer from which a light-sensitive layer is constructed is 0.1 to 0.5 mol.
- 5. A silver halide photographic light-sensitive material as in claim 1, wherein the coupler of formula (I) and the epoxy of formula (II) are coemulsified and dispersed in the form of fine grains in a silver halide emulsion layer.
- 6. A silver halide, photographic light-sensitive material as in claim 5, wherein the coemulsification is effected in the presence of a high-boiling organic solvent.
- 7. A silver halide photographic light-sensitive material as in claim 1, wherein the coupler of formula (I), the epoxy of formula (II), and a ultraviolet absorber of formula (XI) below: ##STR72## wherein R.sub.41, R.sub.42, R.sub.43, R.sub.44 and R.sub.45 may be the same or different, and they represent a hydrogen atom or a substituent, are coemulsified.
- 8. A silver halide photographic light-sensitive material as in claim 7, wherein the ultraviolet absorber is contained in an amount of 1.times.10.sup.-4 to 2.times.10.sup.-3 mol/m.sup.2.
- 9. A silver halide photographic light-sensitive material as in claim 1, which further comprises an alkylhydroquinone represented by formula (XII) below, a hydroquinone sulfonate represented by formula (XIII) below or an amidohydroquinone represented by formula (XIV) below: ##STR73## wherein R.sub.51 and R.sub.52 each represents a hydrogen atom, or a substituted or unsubstituted alkyl group with 1 to 20 carbon atoms, and one of R.sub.51 and R.sub.52 is an alkyl group; ##STR74## wherein R.sub.53 represents a substituted or unsubstituted alkyl group, alkylthio group, amido group, or alkyloxy group, and R.sub.54 represents a sulfo group or a sulfoalkyl group; ##STR75## wherein R.sub.55 represents a hydrogen atom, a halogen atom, or a substituted alkyl group, A represents ##STR76## or -SO.sub.2 -, and R.sub.56 represents a substituted or unsubstituted alkyl group or aryl group.
- 10. A silver halide photographic light-sensitive material as in claim 9, wherein the hydroquinone is contained in an intermediate layer between a red-sensitive silver halide emulsion layer and a green-sensitive silver halide emulsion layer.
