Claims
- 1. A silver halide photographic material comprising a film support having thereon at least one hydrophilic colloid layer, at least one layer of which is a photosensitive silver halide emulsion layer and at least one layer of which contains gelatin as a binder, wherein the film support is a polyester film having a water uptake of at least 0.5 wt%, said water uptake being determined by equilibrating the polyester film for 3 hours at 23.degree. C. and 30% RH, then immersing the film in distilled water at 23.degree. C. for 15 minutes and then measuring the water content using a micro-moisture meter at a drying temperature of 150.degree. C., and the silver halide photographic material contains a vinylsulfone based film hardening agent in at least one gelatin-containing layer in a total amount of from 0.01 to 20 wt% with respect to the total amount of gelatin on a dry basis, present in the silver halide photographic material, said vinylsulfone based film hardening agent is a compound represented by the general formula (I):
- X.sup.1 -SO.sub.2 -L-SO.sub.2 -X.sup.2 (I)
- wherein X.sup.1 and X.sup.2 represent -CH.dbd.CH.sub.2 or -CH.sub.2 CH.sub.2 -Y groups, and X.sup.1 and X.sup.2 may be the same or different; Y represents a group which can be substituted by a nucleophilic reagent having a nucleophilic group, or which can be eliminated in the form of HY by a base; and L is a divalent linking group which may be substituted.
- 2. A silver halide photographic material as in claim 1, wherein the polyester film is a copolymer containing ethylene terephthalate units as a main component.
- 3. A silver halide photographic material as in claim 2, wherein the copolymer polyester film further contains units derived from an aromatic dicarboxylic acid having a metal sulfonate group.
- 4. A silver halide photographic material as in claim 3, wherein the aromatic dicarboxylic acid having a metal sulfonate group is selected from the group consisting of 5-sodiumsulfoisophthalic acid, 2-sodiumsulfoterephthalic acid, 4-sodiumsulfophthalic acid, 4-sodiumsulfo-2,6-naphthalenedicarboxylic acid and compounds in which the sodium is replaced, by potassium or lithium.
- 5. A silver halide photographic material as in claim 2, wherein the copolymer polyester film further contains units derived from aliphatic dicarboxylic acid having from 4 to 20 carbon atoms.
- 6. A silver halide photographic material as in claim 5, wherein the copolymer polyester film further contains one or more segments derived from a poly(alkylene glycol) of molecular weight of from 600 to 20,000.
- 7. A silver halide photographic material as in claim 2, wherein the copolymer polyester film further contains one or more segments derived from a poly(alkylene glycol) of molecular weight of from 600 to 20,000.
- 8. A silver halide photographic material as in claim 7, wherein the one or more segments derived from the poly (alkylene glycol) constitute less than 10 wt% of the copolymer polyester film.
- 9. A silver halide photographic material as in claim 3, wherein the proportion of units derived from an aromatic dicarboxylic acid having a metal sulfonate group is from 2 to 15 mol% with respect to the ethylene terephthalate units contained in the copolymer polyester film.
- 10. A silver halide photographic material as in claim 5, wherein the proportion of units derived from an aliphatic dicarboxylic acid is from 3 to 25 mol% with respect to the ethylene terephthalate units contained in the copolymer polyester film.
- 11. A silver halide photographic material as in claim 1, wherein said at least one gelatin-containing layer further contains a hardening agent other than a vinylsulfone based hardening agent.
- 12. A silver halide photographic material as in claim 1, wherein the total amount of hardening agent constitutes from 0.01 to 20 wt% with respect to the total amount of gelatin, on a dry basis, present in the silver halide photographic material.
- 13. A silver halide photographic material as in claim 12, wherein the vinylsulfone film hardening agent constitutes at least 50 mol% of the total amount of hardening agent.
- 14. A silver halide photographic material as in claim 1, wherein the polyester film has a water content of from 0.6 to 4.0 wt%.
