Claims
- 1. In a process for recording electron beams which comprises imagewise exposing to electron beams a photographic fine grain silver halide emulsion containing fine silver halide grains having a mean grain size by diameter no greater than 0.2 micron and processing said silver halide emulsion, the improvement wherein said photographic fine grain silver halide emulsion contains at least one compound represented by the following formula; ##SPC6##
- wherein A represents an aliphatic group, an aryl group, or a 5- or 6-membered heterocyclic ring containing at least one nitrogen atom selected from the group consisting of a morpholine nucleus, a piperidine nucleus, a 2-thio-4-oxo-thiazolidine nucleus, a thiadiazole nucleus and a 1,3,4-triazole nucleus, R.sub.1 and 2 represent a hydrogen atom or a lower alkyl group, and n represents 0 or 1; said at least one compound being present in an amount sufficient to sensitize said emulsion to electron beams.
- 2. The process of claim 1 wherein A represents an alkyl group of from 1 to 6 carbon atoms, a hydroxyalkyl group, an aralkyl group, an allyl group, an aryl group, or a 5- or 6-membered heterocyclic ring containing at least 1 nitrogen atom selected from the group consisting of a morpholine nucleus, a pyridine nucleus, a piperidine nucleus, an oxazole nucleus, an imidazole nucleus, a thiazole nucleus, a benzoxazole nucleus, a benzimidazole nucleus, benzthiazole nucleus, a pyrimidine nucleus, a thiazolidine nucleus, a thiadiazole nucleus, a triazole nucleus and a tetrazole nucleus.
- 3. The process of claim 2 wherein the mean grain size by diameter of the silver halide particles is from 0.08 to 0.05 micron.
- 4. The process of claim 2 wherein the silver halide emulsion comprises silver bromide.
- 5. The process of claim 2 wherein said at least one compound is: ##SPC7##
- 6. The process of claim 2 wherein said at least one compound is: ##SPC8##
- 7. The process of claim 2 wherein said at least one compound is: ##SPC9##
- 8. The process of claim 2 wherein said at least one compound is: ##SPC10##
- 9. The process of claim 2 wherein said at least one compound is: ##SPC11##
- 10. The process of claim 2 wherein said at least one compound is: ##SPC12##
- 11. The process of claim 2 wherein said at least one compound is: ##SPC13##
- 12. The process of claim 2 wherein said at least one compound is: ##SPC14##
- 13. The process of claim 2 wherein said at least one compound is: ##SPC15##
- 14. The process of claim 2 wherein said at least one compound is: ##SPC16##
- 15. The process of claim 2 wherein said at least one compound is: ##SPC17##
