Claims
- 1. A process for forming an image by use of a silver halide photographic material comprising a silver halide photographic emulsion layer to be used for argon laser beam exposure which process comprises imagewise exposing the photographic material to argon laser beam light for 10.sup.-5 to 10.sup.-7 second, and developing said material said photographic emulsion layer comprising at least one sensitizing dye represented by the following formula: ##STR4## wherein Z, when taken together with the atoms to which it is attached, form a heterocyclic nucleus selected from the group consisting of a pyridine nucleus, a pyrroline nucleus, an oxazole nucleus, a thiazole nucleus and a selenazole nucleus, said nuclei having a substituent or substituents selected from the group consisting of hydrogen, lower alkyl, lower alkoxy, and aryl or said nuclei are fused with a benzene or naphthalene ring which ring can have a substituent or substituents selected from the group consisting of hydrogen, lower alkyl, lower alkoxy, and halogen; Q, when taken together with the atoms to which it is attached, form a heterocyclic nucleus selected from the group consisting of a rhodanine nucleus, a thiohydantoin nucleus, a thiooxazolidinedione nucleus and a thioselenazolidinedione nucleus, said nuclei having a substituent or substituents selected from the group consisting of lower alkyl, lower alkoxy, sulfoalkyl, carboxyalkyl, hydroxyalkyl, allyl and aryl; R is selected from the group consisting of alkyl, alkenyl, aryl, substituted alkyl wherein said substituent is selected from the group consisting of .beta.-hydroxyethyl and .beta.-carboxyethyl; and n is an integer of 0 or --1.
- 2. A Process according to claim 1 wherein said silver halide emulsion is a silver iodobromide emulsion.
- 3. A Process according to claim 1 wherein said silver halide emulsion comprises silver halide grains containing at least 60 mole percent of silver chloride.
- 4. A Process according to claim 3 wherein said silver halide grains have an average grain size of 0.1 to 1.mu. .
- 5. A Process according to claim 1 wherein said silver halide emulsion further comprises at least one of chemical sensitizers selected from the group consisting of noble metal sensitizers, sulfur sensitizers and selenium sensitizers.
- 6. A process according to claim 4 wherein said silver halide emulsion further comprises at least one of chemical sensitizers selected from the group consisting of noble metal sensitizers, sulfur sensitizers and selenium sensitizers.
- 7. A process according to claim 6 wherein said at least one of chemical sensitizers is a combination of the noble metal sensitizers and the sulfur sensitizers.
- 8. A process according to claim 7 wherein said at least one of sensitizing dyes is selected from the group consisting of: ##STR5##
- 9. A process according to claim 1 wherein the amount of sensitizing dye is from about 3 to 500 mg per mole of the silver halide.
