- the present invention relates to an infectious developer used for making photographic printing plates, particularly an infectious developer having excellent preservability which is used for making photographic plates having good image quality.
- Photographic plate for printing can generally be produced by an infectious development of a lithotype photographic sensitive element typically used for produc ing a dotted or line drawing or a hard photographic sensitive element having'high contrast and forming images of excellent sharpness.
- litho-type sensitive elements include lithofilin or lithoplate which is used for recording images on a printed original having a continuous gradation density by dividing the images into meshed dots so that a variation in density changes into a variation in the area of the dots,and litholine film or litholine plate which is used for a printed original having line drawings.
- a half-tone plate is obtained by printing the image of the original onto the litho-type sensitive element through a screen and conducting development.
- An ideal half-tone plate consists of dotted spots having a maximum density and a background having a minimum density. .However, since any-hard photographic sensitiveelement has an intermediate density, areas of intermediate density, called fringe areas, are always formed around the dots. Fringe is not desirable for plate making because it notably deteriorates the quality of printed images. The line drawing image is thought of as continuous series of dotted images. Accordingly, in litholine film or plate, areas of intermediate density are not desirable.
- the developer used for producing photographic plates for printing using a lithotype sensitive element or another hard sensitive element is usually an alkaline infectious developer which contains a dihydroxybenzene type developing agent and an aldehyde-alkali hydro gen sulfite addition product as the preservative.
- Infectious developers of this kind have poor preservability as compared to common black-white developers because the amount of a free sulfite ion is small.'In a developer having a low free sulfite ion concentration, the life of activated hydroquinone is kept for a long period of time and the hydroquinone is infectively activated and accumulated thereby. Consequently, images having a high contrast and low fringe are obtained since the development is carried out rapidly.
- ascorbic acid Since it is essential for an infectious developer to have a good preservability, it is necessary to improve the preservability by adding an antioxidant other than the sulfite. For instance, it is known to add ascorbic acid to an infectious developer (.lap. Pat. Pub. Sho 44-28673). However, ascorbic acid has a poor stability because it is easily decomposed and it is particularly unstable when metal-ions, such as copper or iron ions exist in the developer. Consequently the preservability of the developer is poor. Moreover, ascorbic acid has the fault that it somewhat hinders the progress of the development and causes deterioration of the quality of half-tone dots if added in large amounts.
- the present inventors have found a fact that the preservability of an infectious developer is remarkably improved without bad influence upon image quality by adding atleast onephenol compound represented by the following formula to the infectious developer:
- R R R R and R can be identical or-different and can represent a hydrogen atom, hydrocarbon group, substituted hydrocarbon group, alkoxy group, COOM, $0 M (M represents a hydrogen atom,'a water soluble cation or a hydrocarbon group), halogen atom, S R (R represents a hydrocarbon group or substituted hydrocarbon group), COR, (R represents a hydrogen atom, hydrocarbon group or substituted hydrocarbon group) or NR R (R and R represent each a hydrogen atom, hydrocarbon group or substituted hydrocarbon group.
- the object of the present invention is to provide a developer especially for photographic plate for printing, which does not have a bad influence upon the quality of the formed images and has excellent preservability.
- the preservability of the developer is greatl improved as compared to the use of known preservatives such a; sodium sulfite ascorbic acidTetEf and the resulting photographic images have excellent; quality with low fringe and excellent dots. Moreover,
- any compound of the present invention represented by the above-mentioned formula is effee- I tive for improvingthe preservability of infectious developers, those which are substituted by at least one alkyl group are preferred and those havingan alkyl group with many carbon atoms are most preferred and specific carbon ranges of more preferred groups are more than 2. in this case, the solubility of the compound is important.
- water-soluble groups such as sulfon, carboxyl or hydroxyalkyl groups may be bonded to the nuclei with the substituted hydrocarbon. The most preferred carbon ranges are 3 to 5.
- compounds in which the ortho positions of the'benzene ring is substituted by one or preferably two alkyl groups are especially effective.
- sterically hindered phenols such as those having an isopropyl group, a t-butyl group or a t-amyl fectiveto introduce a sulfo group, a carboxyl group 6% a hydroxyalkyl group 'in addition to the alkyl groups in order to increase the water-solubility of these compounds.
- the water-soluble cations are an alkali metal such as sodium or potassium, and ammonium group.
- the developer-for photographic plates for printing to which the compounds of the present invention are added is the common infectious developer which contains hydroquinone as the developing agent.
- the developer may also contain water-soluble acids, alkalies and salts such as sodium carbonate, sodium hydroxide, acetic acid and boric acid as an alkali agent or a pH buffer agent, aldehyde-alkali hydrogen sulfite addition products, ketone-alkali hydrogen sulfite addition products, sulfites or two or more thereof as an antioxidant, and "alkali halides as a development controlling agent in addition to the hydroquinone.
- the developer may contain, if desired, organic antifogging agents such 'as benzotriazole and 1-phenyl-5-mercapto-tetrazole, polyalkylene oxides, amine compounds or organic solvents such as triethylene glycol, dimethylformamide, methyl alcohol and cellosolve in the amount of l 300 ml per liter of the developer.
- organic antifogging agents such 'as benzotriazole and 1-phenyl-5-mercapto-tetrazole
- polyalkylene oxides such as triethylene glycol, dimethylformamide, methyl alcohol and cellosolve in the amount of l 300 ml per liter of the developer.
- a sulfite ion buffer such as a formaldehyde-sodium hydrogen sulfite addition prodact is used.
- the free sulfite ion concentration is controlled by additionally adding sulfite such as alsuch as formaldehyde-sodium hydrogen sulfite addition product, or a ketone-alkali hydrogen sulfite such as acetone-sodium hydrogen sulfite addition product.
- the preservability is remarkably improved by adding the abovementioned compounds to the infectious developer containing no alkali sulfite other than a sulfite ion buffer such as formaldehyde-sodium sulfite addition product, and the preservability can be remarkably improved by adding to the infectious developer less than g (per liter of the developer) of an alkalisulfite in addition to the sulfite ion buffer.
- Sulfite may be added to the developer with the compound of the invention, whereby the developer shows stronger preservability than that containing only sulfite.
- a range of additional product is to 100 g, preferably to 70 g, per one liter of developer.
- alkali in the above essential components, alkali should be added; but the amount thereof may be such amount that pH of the developer is alkali property, especially pH 8 or more, and more preferably pH 9 pH 11.
- the developer is prepared as a liquid or powder composition and mixed, diluted or dissolved at the time of use, it is effective at that time to previously add the compounds of the present invention to the composition. in the case of using a liquid composition, it is particularly effective to add the compounds to such a liquid composition because the preservability of the liquid compositionis remarkably increased by the addition of the compounds.
- Common liquid compositions consist of two liquids, that is, one part containing the developing agent, a second part containing an alkali.
- the compound of the present invention may be added to either part, it is more preferred to add to the part containing the developing agent, by which the preservability of the liquid developer can be further improved and the stability of the developer after preparation of the infectious developer by dilution can be remarkably improved.
- it is possible to improve the preservability of the developer by adding the compounds of the present invention during or after development of the photographic plate for print- As emulsions used to form photographic plates for printing, common silver halide photographic emulsions.
- h araqu'man is 5 to 56g; preferably 16 present invention vare added at the preparation of the developer.
- bromoiodide can be used.
- silver chlorobromide is suitably used.
- These silver halides are dispersed in gelatin or a medium comprising gelatin and a synthetic high molecular substance to form an emulsion.
- the emulsion may be chemically sensitized by compounds containing unstable sulfur such as sodium such as formaldehyde or mucochloric acid, and may contain surface active agents such as saponin so as to make application easy. These additives are added for their well known prior art functions in conventional amounts.
- EXAMPLE 1 sensitized with gold and sulfur and then spectrally sensitized with 3-carboxymethyl-5-[ 2-( 3- ethylthiazolinidene)-ethylidene] rhodamine, said emulsion containing polyoxyethylene nonylphenyl ether having ethylene oxide group number of 50, mucochloric acid and polybutylmethacrylate.
