Claims
- 1. A silver halide photographic material comprising a support having thereon at least one silver halide emulsion layer, wherein at least one silver halide emulsion layer contains a silver halide emulsion obtained by treating a silver halide emulsion containing a dye previously added thereto with a solid adsorbent which is a porous synthetic organic resin without an ion-exchange group to thereby desorb the dye adsorbed.
- 2. A silver halide photographic material as in claim 1, wherein said silver halide emulsion is one obtained by treating a silver halide emulsion with the solid adsorbent in the presence of a desorption accelerator for silver halide grains.
- 3. A silver halide photographic material as in claim 1, wherein said silver halide emulsion which is treated with said solid adsorbent comprises grains formed in the presence of the dye.
- 4. A silver halide photographic material as in claim 1, wherein said silver halide emulsion which is treated with said solid adsorbent is an emulsion chemically sensitized in the presence of the dye.
- 5. A silver halide photographic material as in claim 1, wherein said photographic material contains a silver halide emulsion obtained by desorbing a dye and then adding a spectral sensitizing dye.
- 6. A silver halide photographic material as in claim 1, wherein a nitrogen-containing heterocyclic compound having no spectrally sensitizing capability has been adsorbed onto the silver halide emulsion and then desorbed by a porous organic synthetic resin without an ion exchange group.
- 7. A silver halide photographic material as in claim 6, wherein the nitrogen-containing heterocyclic compound and the dye are added simultaneously to the silver halide emulsion .and are desorbed by the solid adsorbent at the same time.
- 8. A silver halide photographic material as in claim 7, wherein said silver halide emulsion which is treated with said solid adsorbent comprises grains formed in the presence of the dye and the nitrogen-containing heterocyclic compound having no spectrally sensitizing capability.
- 9. A silver halide photographic material as in claim 7, wherein said silver halide emulsion which is treated with said solid adsorbent is an emulsion chemically sensitized in the presence of the dye and the nitrogen-containing heterocyclic compound having no spectrally sensitizing capability.
- 10. A silver halide photographic material as in claim 6, wherein the nitrogen-containing heterocyclic compound is added to the silver halide emulsion during formation of the grains of the emulsion.
- 11. A silver halide photographic material as in claim 10, wherein the dye is added after grain formation.
- 12. A silver halide photographic material as in claim 11, wherein the formed grains are treated with the solid adsorbent to desorb the nitrogen-containing heterocyclic compound, the dye is then added, and after completion of chemical sensitization the silver halide emulsion is treated with the solid adsorbent to desorb the dye.
- 13. The silver halide photographic material as in claim 11, wherein the nitrogen containing heterocyclic compound and the dye are desorbed at the same time with the solid adsorbent.
- 14. A silver halide photographic material as in claim 6, wherein the nitrogen-containing heterocyclic compound is added after grain formation of the silver halide emulsion.
- 15. A silver halide photographic material as in claim 1, wherein a silver halide solvent has been adsorbed onto the silver halide emulsion and then desorbed by a porous organic synthetic resin without an ion exchange group.
- 16. A silver halide photographic material as in claim 15, wherein the silver halide solvent and the dye are added simultaneously to the silver halide emulsion and are desorbed by the solid adsorbent at the same time.
- 17. A silver halide photographic material as in claim 16, wherein said silver halide emulsion which is treated with said solid adsorbent comprises grains formed in the presence of the dye and the silver halide solvent having no spectrally sensitizing capability.
- 18. A silver halide photographic material as in claim 16, wherein said silver halide emulsion which is treated with said solid adsorbent is an emulsion chemically sensitized in the presence of the dye and the silver halide solvent.
- 19. A silver halide photographic material as in claim 15, wherein the silver halide solvent is added to the silver halide emulsion during formation of the grains of the emulsion.
- 20. A silver halide photographic material as in claim 19, wherein the dye is added after grain formation.
- 21. A silver halide photographic material as in claim 20, wherein the formed grains are treated with the solid adsorbent to desorb the silver halide solvent, the dye is then added, and after completion of chemical sensitization the silver halide emulsion is treated with the solid adsorbent to desorb the dye.
- 22. The silver halide photographic material as in claim 20, wherein the silver halide solvent and the dye are desorbed at the same time with the solid adsorbent.
- 23. A silver halide photographic material as in claim 15, wherein the silver halide solvent is added after grain formation of the silver halide emulsion.
