Definitions
- the photoactivators Upon exposure to light the photoactivators provide free radicals which cause a dye-forming or bleaching color change.
- a variety of so-called printing-out-type light-sensitive materials which develop images by action of light have previously been known.
- Such materials include silver printing-out type light sensitive materials chiefly containing light-sensitive silver salts; blue print light-sensitive materials mainly containing light-sensitive iron salts; the compositions using organic halogen-containing compounds capable of forming free halogen radicals by action of light, such as disclosed in US. Pats. Nos. 3,042,515 to 3,042,519; and compositions containing as light-sensitive components leucocyanides of triphenylmethane dyes, such as set forth in US. Pat. No. 2,676,887.
- the light-sensitive photographic material of the present invention avoids such drawbacks as mentioned above and has excellent overall quality as compared with said conventional photographic materials.
- the photographic material of the present invention is convenient to use, and the resulting image is not only excellent in contrast and resolution but also is high in stability.
- the light-sensitive photographic material of the present invention is composed mainly of a photoactivator capable of being made reactive by action of light and which is selected from the group consisting of N-oxide compounds of pyridine and quinoline, or quaternary salts thereof, and a second color-modifier component which shows a visible color change by reaction with the light-activated photoactivator.
- Arylamine, leuco-form, arylmethane, and azomethine dyes are among the many compounds useful as the second component of the material.
- the material of the invention is readily prepared by coating on a support of paper or the like a solution containing the major components and drying the coating.
- the coating composition may advantageously include binder resins and light sensitizing compounds.
- the photographic material of the present invention directly shows a visible change by exposure to ultraviolet light or visible light. Therefore, when the material is placed under a photographic negative or manuscript and is subjected to printing by use of such light, a clear image can be immediately obtained which can subsequently'be made into a stable image through fixing operations including heating or dissolving out the active components.
- any of the compounds useful as the components employed in the photographic material of the present invention are non-toxic and stable substances and are obtainable at low costs. Therefore, the present photographic material is not only safe in handling but also is excellent in storability, and can be prepared at low cost.
- the first component employed in the present invention is a photoactivator capable of being brought into a reactive state by action of light, and is an N-oxide compound of pyridine or quinoline, or a quaternary salt thereof, which is represented by the general formula wherein n is an integer of l or 2; R is a hydrogen atom or a C -C alkyl, aralkyl, halogen, nitrile, mercapto or formyl group; R is a C -C alkyl or aralkyl group, or is a C -C alkyl or aralkyl group, or is a C 0 alkylene or xylylene group in case n is 2; X is an anion; and Z is two separate hydrogen atoms, or atomic groups necessary to complete a benzene irng.
- Such photoactivators include: N-oxide derivatives such Useful quaternary salts of N-oxides include N-benzyloxypyridinium bromide, N,N'-o-Xylylenedioxy-bis-2-methylpyridinium bromide, N,N'-xylylenedioxy-bis-pyridinium bromide, N-ethoxy-Z,4-dimethylpyridinium iodide, N-methoxyquinoline iodide, N-benzyloxyquinolinium bromide, N,N-o-xylylenedioxy-bis-Z-methylquinolinium bromide, N,N-p-xylylenedioxy-bis-quinolinium bromide, N-ethoxy-4-chloropyridinium iodide, N-methoxypyridinium iodide, N-methoxypyridinium-p-toluenesulfonate, N-methoxy-
- N,N'-o-xylylenedioxy-bis-2-cyanoquinolium bromide N,N'-o-xylylenedioxy-bis-2-cyano-4-chloroquinolium bromide, N,N'-p-xylylenedioxy-bis-pyridinium bromide, N,N'-propylenedioxy-bis-pyridinium bromide and N,N'-butylenedioxy-bis-pyridinium bromide.
- the second components employed in the present invention in combination with the aforesaid photoactivators do not cause visible changes by themselves by action of light, as in the case of photoactivators, but cause visible changes by reaction with the photoactivators which have become reactive by action of light.
- the second components having such properties chemical substances of a markedly wide scope may be used and it is thus impractical to exemplify them as substances having structures within a specific scope. In short, however, all such substances which cause visible changes when exposed to light together with the aforesaid photoactivators are useable as the second components in the present invention. Therefore, in selecting the second components, there may be employed the following simple test method.
- a substance desired to be used and any of the aforesaid photoactivators are dissolved together in an appropriate solvent.
- the solution is applied to a piece of paper, and the paper is dried and is then exposed to light. If the paper shows a visible color change, the tested substance is useable as the second component in the present invention.
- Compounds which have been found to be effective as the second components according to the above test method are classified into two types; one involves substances which are originally colorless, but develop a distinct color by action of free radicals generated from the photoactivators, and the other involves substances which originally have a distinct color, but may be decolored or bleached by action of the free radicals.
- a light sensitive photographic material prepared by using the former type as the second component is originally colorless, but develops color by action of light and hence is used in a so-called negative-positive process, while a photographic material prepared by using the latter type is used in a positivepositive process.
- Typical as the second components belonging to the former type are arylamines including, in addition to the ordinary arylamines, so-called leuco coloring matters which are reduced types of coloring matters having amino groups or substituted amino groups.
- Examples of such components are diphenylamine,
- Rhodamine B Cl. 45,170
- Rhodamine 3B Cl. 41,175)
- Rhodamine 12GM C.I. 45,310
- Suden Blue G Cl. 61,520
- Celliton Blue C.I.
- the light-sensitive photographic material of the present invention which is composed of the above-mentioned photoactivator and the second component, is preferably obtained by dissolving the components in a solvent together with a suitable high molecular weight binder having a film-forming property, and applying the solution to a suitable support such as paper of film base, followed by drying.
- high molecular Weight binders there are various compounds including, for example, cellulose derivatives such as acetyl cellulose, acetylbutyryl cellulose and ethyl cellulose, polymers and copolymers of vinyl chloride, vinylidene chloride, vinyl acetate, acrylate and styrene, styrene-maleic anhydride copolymer, and synthetic rubbers such as cyclized rubbers, acryl rubbers and butadiene copolymers.
- cellulose derivatives such as acetyl cellulose, acetylbutyryl cellulose and ethyl cellulose
- polymers and copolymers of vinyl chloride, vinylidene chloride, vinyl acetate, acrylate and styrene, styrene-maleic anhydride copolymer and synthetic rubbers such as cyclized rubbers, acryl rubbers and butadiene copolymers.
- the color change in the photographic material of the present invention is due to a free radiacl formed from the photoactivator by action of light, particularly ultraviolet light.
- the light sensitivity of the present photographic materials can further be enhanced by addition of suitable sensitizers.
- sensitizers there are two kinds; those belonging to so-called color sensitizers which broden the light-sensitive wave length area of the photographic materials to increase the light sensitivity thereof and those belonging to true sensitizers which increase the light sensitivity regardless of the light-sensitive wave length area.
- sensitizers belonging to the former there are effectively used acridine, cyanine, merocyanine and styrene dyes which have been employed as light-sensitive coloring matters in the conventional silver salt photographic method.
- acridine, cyanine, merocyanine and styrene dyes which have been employed as light-sensitive coloring matters in the conventional silver salt photographic method.
- examples of these are Acridine Orange, Acridine Red, Rose Bengal, pinacyanol, pinakryptol yellow,
- aldehydes as, for example, benzaldehyde, dimethylaminobenzaldehyde, orthophthalodialdehyde, salicylaldehyde, anisaldehyde, phenylacetaldehyde, ascorbic acid, benzaldehyde-sulfonic acid and succinaldehyde.
- the light sensitivity of the present photographic materials can be increased manyfold.
- the photographic material of the present invention is fixed, after printing, by being subjected to either heating or solvent treatment.
- a heat fixing agent promotes the fixing efiect and a stable image can be more readily obtained.
- Etfective as such heat fixing agents are urea and urea derivatives such as methylurea, ethylurea, diphenylurea and thiourea, sodium sulfite or bisulfite and aldehyde or ketone addition products such as, for example, rongalite, sodium bisulfite-benzaldehyde addition product and sodium bisulfite-cyclohexanone addition product, and reducing compounds such as stannous chloride.
- the heat fixing agent is incorporated into a binder solution together with photoactivator and color modifier. If the heat fixing agent employed is insoluble in the binder solution, it is formed into an aqueous solution at a concentration of about 0.5-5% and is applied onto the surface of the light-sensitive layer of the present photographic material.
- the photographic material of the present invention is obtained by dissolving the above-mentioned components in a binder solution and applying, according to any com mon procedure, the thus prepared solution onto a suitable support.
- preferable quantitative proportions of the individual components are as follows:
- the fixing is effected in such a manner that the material after printing is either heated to stabilize the residual photoactivator and color modifier, or is treated with a suitable solvent to remove such components.
- the heat fixing is simply carried out by passing the material between rolls heated a surface temperature of about 180 C.
- a suitable solvent there is selected and used such a suitable solvent as to dissolve the photoactivator without dissolving the coloring matter formed by exposure to light or the coloring matter remaining without being discolored or decolored.
- a solvent comprising a 50:50 mixture of ethyl acetate and cyclohexane is most suitable for a negative-positive type photographic material using the previously cited a-bromopyridine-N-oxide as a photoactivator and diphenylamine as a color modifier, and gasoline is most preferable for a photographic material using N-methoxy-Z-methylquinolinium iodide as a photoactivator and Lucocrystal Violet as a color modifier.
- Such solvents as trichloroethylene, methanol and acetone dissolve out color images formed and hence are not usable.
- Example 1 A photographic paper, which had been subjected to surface treatment by application of 11.5 g./m. of polyvinyl alcohol having a polymerization degree of about 600, was coated under a yellow safety lamp with 30 cc./ m. of a light-sensitive solution having the following composition and dried to obtain a light-sensitive photographic material:
