Definitions
- ABSTRACT A lith type photographic material, the development of which can be easily controlled, is obtained by use of a fine grain photographic silver halide emulsion to [30] Foreign Application p i Dam which have been added a polyethylene oxide, or a de- Ma 25 1972 la an 476209 rivative thereof, and a triazoline derivative, or a mumy p meric compound thereof, having the general formula,
- a photographic film which is used in the graphic arts field in order to reproduce a halftone or linear image should be one capable of providing extremely high contrast and high sharpness.
- a lith type photographic material prepared by use of a fine grain high contrast emulsion comprising silver chlorobromide containing less than 40 mole 7( of silver bromide.
- an infections developer which has an extremely low free sulfite ion concentration and which contains only hydroquinone as the developing agent.
- a photographic material prepared by use of a fine granular silver chlorobromide emulsion containing at least 60 mole% of silver chloride to which has been added a polyethylene oxide having a molecular weight of, for example, 1,000 or more, or its derivative, e.g. oleyl ether.
- the polyethylene oxide has such adverse effects that it strongly inhibits the development of the photographic material, and particularly when the development is carried out for a short period of time, the photographic material not only difficultly exhibits its sensitivity but also becomes great in sensitivity variation when the development time is short and becomes small in sensitivity variation when the development time is long. According to a process in which the development time is merely varied proportionately, therefore, there is brought about such drawback that the development of the photographic material is difficultly controlled.
- An object of the present invention is to provide a lith type photographic material prepared in the aforesaid manner, the development of which has been made easily controllable by overcoming only the adverse effects of the polyethylene oxide while preserving the features thereof to promote the development of the photographic material particularly in a short time development as well as to make the sensitivity variation thereof smaller.
- the above-mentioned object of the present invention is accomplished by providing a photographic material prepared by use of a fine grain photographic silver halide emulsion containing at least 60 mole% of silver chloride, less than 40 mole% of silver-bromide and less than several mole% of silver iodide to which have been added a polyethylene oxide, or a derivative thereof, and a triazoline derivative mentioned below.
- the triazoline derivative which is effectively used in the present invention, is a compound represented by the general formula,
- R is a hydrogen atom or an alkyl group having 1 to 5 carbon atoms; and A is an amino group, an acid amide group having 2 or 3 carbon atoms, an alkyl group having 1 to 3 carbon atoms, or an ally] group, which compound naturally includes tautomcric compounds thereof as well, though this is a matter of course.
- the above-mentioned compound may be added directly to a developer, but is preferably added to an emulsion.
- Typical examples of the said compound are as follows:
- the compound can be used in combination with an indolizine or tetrazole type stabilizer which is ordinarily used in the field of photography. It is well known that the indolizine or tetrazole type stabilizer inhibits the development of photosensitive material. When the compound of the present invention is used in combination therewith, the inhibited developability of photographic material can be restored.
- the amount of the polyethylene oxide or derivative thereof is preferably 10 mgl g per mole of the silver halide.
- each sample was exposed and then developed with D-85 formulated by Eastman Kodak Co. which is the typical infectious developer mentioned previously.
- the developed sample was subjected to stopping, fixing, water-washing and drying, and measured in photographic properties to obtain the results as set forth in Table l.
- Example 2 A gelatin-silver chloroiodide emulsion containing 30 mole% of silver bromide was prepared according toa socalled reverse mixing method, in which halogen salts are added after addition of silver nitrate, and was then equally divided into 5 portions. To each of the th'us divided emulsions were added in such amounts as shown in Table 2 P.E.O. and a 4-amino-3-alkyl (R)-l,2,4- triazoline-S-thione (referred to as l). Thereafter, each emulsion was incorporated with ordinary photographic additives such as sensitizing dye and the like, and then coated and dried in the same manner as in Example 1 to prepare a sample. The thus prepared sample was exposed and then developed with the same developer as in Example 1. Photographic properties of each sample when developed for a development time of 2% minutes were as set forth in Table 2. Further, sensitivity variation of each sample when the development time was varied was as shown in FlG. 1.
- Example 3 A fine grain gelatin-silver halide emulsion containing mole% of silver chloride, 24 mole% of silver bromide and 1 mole% of silver iodide was prepared according to a method, in which silver nitrate and halogen salts were simultaneouslyadded, and was then divided into 5 portions. To each of the thus divided emulsions were added in such amounts as shown in Table 3 P.E.O. and a 3-alkyl( R)-4-alkyl (R' )-l ,2,4-triazoline-5- thione (referred to as ll"). Thereafter, each emulsion was treated in the same manner as in Example 1 to prepare a sample.
- Example l The thus prepared sample was exposed and then developed with the same developer as in Example l for a development time varying from 2 minutes to 4% minutes.
- the sensitivity difference between two samples developed for 2 minutes and 4 /4 minutes was represented as the variation of relative sensitivity based on the sensitivity of the sample developed for 2 minutes to obtain the results as set forth in Table 3.
- a lithographic photographic material which comprises a fine grain silver halide emulsion, at least 60 mole 7: of the silver halide being silver chloride, a polyethylene oxide or polyethylene oxide oleyl ether and a triazoline derivative or a tautomeric compound thereof, represented by the general formula wherein R is a hydrogen atom or an alkyl group having 1 to 5 carbon atoms, and A is an amino group, an acid amide group having 2 to 3 carbon atoms or an ally] group.
- a lithographic photographic material according to claim 1 which additionally contains an indolizine or tetrazole stabilizer.
- a lithographic photographic emulsion according to claim 8 wherein R is alkyl of l to 5 carbon atoms.
- a process for the production of developed lithographic photographic material comprising developing the imagewise exposed lithographic photographic material of claim 1 with a lithographic developer.
