Definitions
- This invention relates to photographic materials, and more particularly, to high contrast photographic silver halide emulsrons.
- a silver chlorobromide emulsion having a high content of silver bromide needs a longer developing time in order to obtain a definite contrast (compared with another silver chlorobromide emulsion having a lower content of silver bromide).
- the addition of polyalkylene oxide derivatives, well-known as coating agents results in a remarkable decrease in the rate of infectious development. Therefore, it is important, in the case of employing an infectious developer of this kind, to accelerate the development and to shorten the time necessary for attaining a definite density or contrast.
- the first aspect of the present invention provides an improved light-sensitive photographic material which results in rapid development utilizing an infectious developer.
- the photographic light-sensitive material basically comprises a support having coated thereon at least one silver halide emulsion layer or at least one silver halide emulsion layer and a photographic layer adjacent thereto containing a compound represented by the following formula:
- R is a member selected from the group consisting of an alkyl group having one to five carbon atoms, a hydroxyalkyl group having one to five carbon atoms, a tetrafurfuryl group and an aralkyl group having seven to 12 carbon atoms
- R, and R each is a member selected from the group consisting of a hydrogen atom, an alkyl group having one to five carbon atoms and an atomic group capable of forming a ring through linkage with R and R and Q is a member selected from the group consisting of a sulfur atom and an imino group.
- the present invention further comprises a method of photographic reproduction comprising exposing a photographic light-sensitive material as described above, and subsequently developing the exposed photographic material with an infectious developer containing hydroquinone.
- the amounts of the compounds added to the photographic emulsion varies according to the type of emulsion and compound. In general, it is preferable to add in a proportion of 0.05 to 10 g. of compounds to l mole of silver halide contained in the photographic emulsion.
- Preparation of a photographic emulsion is generally carried out by three steps, that is to say, (1) precipitation and digestion of silver halide, i.e., physical digestion, (2) removal of excess salts by washing with water and (3) chemical digestion, i.e., after ripening, to increase the sensitivity.
- the compounds of the invention may be added to the emulsion at any state, but the best results can be obtained when added after the chemical digestion and before coating.
- the compounds are dissolved in solvents that have no determinal effect on the emulsion, for example, water, a lower alcohol such as methanol or ethanol, ketones such as acetone, and are added to the emulsion.
- solvents that have no determinal effect on the emulsion, for example, water, a lower alcohol such as methanol or ethanol, ketones such as acetone, and are added to the emulsion.
- These chemicals are ordinarily added directly to the emulsion, but if desired, they may be added to
- the photographic emulsions that can be employed in this invention are ones such as silver chloride, silver bromide, silver chlorobromide, silver iodobromide and silver chloroiodobromide. Furthermore, a direct reversal emulsion, such as the Herschel effect or the solarization type, may be used.
- the emulsion may be chemically sensitized by the wellknown art methods using one or more unstable sulfur-containing compounds such as ammonium thiosulfate and arylthiourea (Cf. P. Glafkides "Chemie Photographique” ll-Ed., p. 297-299 (1957)), and gold compounds such as a complex of monovalent gold and thiocyanic acid (cf. ibid., p. 301).
- the emulsion also may be optically sensitized by the addition of a sensitizing dye,such as cyanine dyes or merocyanine dyed (cf. Shinichi Kikuchi, Kagaku Shashin Binran (Handbook of Scientific Photography, p.
- the emulsion may be hardened by hardeners such as formaldehyde or mucochloric acid, and may contain surface active materials, such as saponin, so as to make coating easy.
- a film designed so as to obtain a particularly high contrast by development using an infectious developer is known as a lithographic film.
- These light-sensitive materials of the lithtype consist generally of a silver chlorobromide emulsion having a high content of silver chloride, and are suitable for making the production of half tone dots by means of a glass screen or a contact screen.
- the compounds of the invention are added to the emulsion of the above-identified lithographic film, exposed to a halftone image and developed with the infectious developer, the developing time required for the product of halftone dots of high density is shortened and, accordingly, the optimum range of developing time, that is development latitude, is enlarged. Consequently, over a broader development time range, optimum dot quality is obtained.
- the films were exposed for l seconds through a stepwise optical wedge having a step difference of 0.1 by the use of a tungsten lamp (2666 K) as a light source, and then developed in a developer of the following composikyl group having one to five carbon atoms, a tetrafurfuryl group and an aralkyl group having seven to 12 carbon atoms, and Q is a member selected from the group consisting of a sulfur atom and an imino group.
- a photographic light-sensitive material comprising a support having coated thereon at least one silver halide emulsion layer containing a compound or salt thereof represented by the following formula,
- R2 is a member selected from the group consisting of an alkyl group having one to five carbon atoms, a hydroxyalkyl group having one to five carbon atoms, a tetrafurfuryl group and an aralkyl group having seven to 12 carbon atoms
- R, and R each is a member selected from the group consisting of a hydrogen atom, an alkyl group having one to five carbon atoms and an atomic group capable of forming a ring through linkage with R and R and Q is a member selected from the group consistingof a sulfur atom and an imino group.
- the photographic light-sensitive material as claimed in claim 1 wherein said compound is one member selected from the group consisting of s-benzylsulfenyldithiocarboxydimethylamine, N-(s-benzylsulfenyldithiocarboxy) (sbenzylsulfenyldithiocarboxy) piperidine, l-chlorophenyl-4-(sbenzylsulfenyldithiocarboxy) piperazine, s-4-isopropylbenzylsulfenyldithiocarboxymorpholine, N-(s-B-hydroxyethylsulfenyldithiocarboxy) morpholine.
