Abstract
The stability to light, especially to sunlight, of organic substrates having an absorption maximum between 300 and 800 nm is improved by the use of a metal chelate of one of four general formulae each of which contains the central structure <IMAGE> wherein M represents an atom of Cu, Co, Ni, Pd or Pt, and the substituents on the N atoms are each hydrogen, alkyl, aryl or hydroxy or together are the non-metallic atoms necessary to complete a 5 or 6-membered ring together with the metal atom; the other substituents can be various organic groups or halogen atoms or can together complete a benzene ring which can be substituted. Examples of synthesis of the complexes are given. The metal chelate compound is mixed with the substrate material, which usually contains a dye, or is put into an adjacent layer thereto in a multilayered colour photographic material or into a mordanting layer of a diffusion-transfer image-receiving element. The dye may be the dye of a color photograph. Details of suitable color couplers are given. 102 specific compounds are shown.
Description
SPECIFICATION
Method for stabilizing organic materials, including dye images, to light
The present invention relates to stabilizing organic substrate materials and, more particularly, to stabilizing organic compounds and particularly photographic dye images to light.
In general, it is widely known that organic substrate materials, for example, organic dyes tend to fade or discolor by the action of light and in the fields of inks, textile dyeing color photography, etc., means of improving the light fastness of organic dyes, preventing fading or discoloring of such organic dyes, etc., have been investigated. Many methods for reducing the occurrence of fading or discoioring or increasing the light fastness of these organic substrate materials have been reported. For example, U.S.
Patent 3,432,300 discloses that the resistance or stabilization of organic compounds such as indolophenol dyes, indoaniline dyes, azo dyes, and azomethine dyes to visible light and ultraviolet rays is improved by mixing them with a phenol type compound having fused heterocyclic ring.
Generally, in the field of silver halide photographic materials, various methods are known for improving the stability of color images, that is, the images of dyes such as azomethine dyes or indoaniline dyes formed by the reaction of the oxidation product of an aromatic primary amine color developing agent and couplers as described in C. E. K. Mees and T. H. James; The Theory of the
Photographic Process; Chapter 17, published in 1967 by Macmillan Co. For example, there are the hydroquinone derivatives described in U.S. Patents 2,360,290; 2,418,613, 2,675,314, 2,701,197, 2,704,713,2,728,659, 2,732,300,2,735,765, 2,710,801 and 2,816,028; and U. K. Patent No.
1,363,921, the gallic acid derivatives described in U. S. Patents 3,457,079 and 3,069,262 and
Japanese Patent Publication No. 13,496/68, the p-alkoxyphenols described in U.S. Patents 2,735,765 and 3,698,909, and the derivatives such as chroman and cumarin described in U. S. Patents 3,432,300, 3,573,050,3,574,627, 3,764,337, 3,574,626, 3,698,909 and 4,015,990. However, these compounds have an effect as a fading preventing agent or discoloring preventing agent for color images but the effect is insufficient.
Also, a method for improving the stability of organic compounds to light by using an azomethine quenching compound of which the absorption maximum is at a longer wavelength than the absorption maximum of the substrate material is described in U. K. Patent No. 1 451,000 or U. S. Patent 4,050,938 to Smith Jr. et al. However, since the azomethine quenching compound itself has a deep color, the use of such a compound is disadvantageous in the point that it influences greatly on the color hue of the base material. In addition, it has also be found by the inventors that such a quenching compound adversely affects photographic speed, i.e., causes serious desensitization.
Also, the use of metal complexes for the prevention of light deterioration of polymers is described by P. Guilloryand R. S. Becker in Journal of Polymer Science, Polym. Chem. Ed., 12,993(1974) and by R. P. R. Ranaweera and G. Scott in Journal of Science, Polym. Lett., Ed., 13,71(1975) and further a method of stabilizing dyes by metal complexes is described in Japanese Patent Application ,(OPI) No. 87,649/75 and "Research Disclosure", 15162(1 976).However, since the fading prevention effect itself of these complexes is not so high and the solubility thereof in organic solvents is not high, it is difficult to add the complexes in an amount sufficient for obtaining the desired fading prevention effect. Furthermore, these complexes themselves are greatly colored and hence they have such difficulty that if a large amount of the complex is used, it gives bad influences on the color hue and the purity of the organic materials, in particular, dyes.
An object of this invention is to provide a method of improving the stability of organic substrate materials to light.
Another object of this invention is to provide a method of improving the stability of organic substrate materials and, in particular, dyes to light without degrading their hue and purity.
Still another object of this invention is to provide a method of improving the stability of organic substrate materials to light using a particular stabilizer having high solubility in organic solvents and high miscibility with the organic substrate materials.
A further object of this invention is to provide a method of improving the stability of dyes forming color photographic images to light.
Another object of this invention is to provide a method of improving the light fastness of dyes formed by the reaction of an oxidized aromatic primary amino color developing agent and color couplers.
A further object of the present invention is to provide a diffusion transfer color photographic material incorporating a particular stabilizer in which the transferred dye images possess improved light fastness.
Still a further object of the present invention is to improve the light fastness of colored polymers such as encountered in agricultural vinyl sheets, umbrellas, tents, etc.
The method of this invention consists in causing the coexistence of at least one of the complexes shown by the following formulae I, II, Ill or IV with an organic substrate material having an absorption maximum in a wave length region of from 300 n. m. to 800 n. m.:
wherein M represents Cu, Co, Ni, Pd or Pt; R1, R2, R3 and R4 each represents a hydrogen atom, a halogen atom, a cyano group or an alkyl group, an aryl group, a cycloalkyl group, or a heterocyclic group bonded directly or through a divalent connecting group to the carbon atom of a benzene ring; or R1 and R2; R2 and R3; or R3 and R4 combine to represent the non-metallic atoms necessary to complete a 6-membered ring; R5 and R8 each represent a hydrogen atom, an alkyl group or an aryl group; Re represents hydrogen atom, an alkyl group, an aryl group, or a hydroxyl grop;R7 represents an alkyl group or an aryl group; and
Z represents the non-metallic atoms necessary to complete a 5-membered or 6-membered ring.
The terms "in the presence of" or "coexistant with" as used in the specification refer not only to the coexistence of the substrate material and the compounds of formulae (I)--(IV) in the same solution, dispersion, emulsion or layer, but also to the existence of the organic substrate material and the complex in, for example, adjacent layers of a multilayer photographic material. As long as the complex is associated with the organic substrate material in some way that it can improve the light fastness of the organic substrate material, it is used "in the presence of' or "coexists with" the substrate for purposes of the present invention.In particular, the terms include the embodiments of the invention discussed later in which an organic substrate material such as a photographic dye or a photographic dye image providing material is coated in one layer with the complexes used in the present invention, or the substrate material and complex are coated in separate layers of a photographic material such that upon migration or diffusion the two materials interact to improve the light fastness of the substrate material.
As described above, the invention provides a method of improving the light fastness or light resistance of organic substrate materials (organic materials). The term "organic substrate material" or "substrate material" used in the specification includes materials which appear colored or colorless to the human eye under sunlight and thus includes not only materials having an absorption maximum in the visible region but also optical whitening agents or materials having an absorption maximum in the infrared region. Thus, in this invention, the organic substrate materials include organic materials having an absorption maximum in a region from about 300 nm in ultraviolet region to about 800 nm in infrared region.
These organic substrate materials occur particularly in photographic materials, e.g., color films, prints and diffusion-transfer units, in colored polymers useful as agricultural vinyl cover sheets, umbrellas or tents; fluorescent whitening agents; and dyed textiles; and this invention is directed to improving the light fastness of these materials in each of these fields.
The term "dye" or "coloring matter" used in this invention are organic substrate materials which appear colored to the human eye under sun light
The term "light" used in this invention refers to electromagnetic radiation of wavelengths shorter than about 800 nm and includes ultraviolet rays of wavelength shorter than about 400 nm, visible radiation of from about 400 nm to about 700 nm, and infrared rays of from about 700 nm to about 800 nm.

General synthesis methods of the above-described complexes are described in G. W. Everett and
A. Chakravorty; "Metal Complexes of Schiff Bases and #-Ketoamines", "Inorganic Chemistry", 783(1966), L. Sacconi; "Coord. Chem. Ref.", 1, 126(1966) and summarized below.
(1) Synthesis of complexes of the formula (I) or (III) wherein R6 is hydrogen:
To a solution of 0.5 mol of alkali hydroxides such as sodium hydroxide in ca. 130 ml of low boiling point alcohols such as methanol, 0.5 mol of 2-acylphenol is added to completely dissolve therein. The
resulting solution is gradually added to an aqueous solution of 0.05 mol of a metal halide such as nickel
chloride. The precipitate formed is separated by filtration. To 5 g of the so obtained compound is added
100 ml of concentrated NH3 water. The mixture is stirred for 3 days at ambient temperature. Red-brown
precipitates are obtained. After isolation, the product is purified in a conventional manner.
(2) Synthesis of complexes of the formula (I) or (Ill) wherein R8 is hydroxy:
A solution of 1 mol of oximes (obtained by reacting a 2-acylphenol with hydroxylamine sulfate in a conventional manner) in alcohols such as ethanol is refluxed. To the solution is added dropwise an alcohol solution of 0.5 mol of a metal halide such as nickel chloride. After completion of the addition, the solvent is evaporated off. The resulting residue is purified in a conventional manner.
(3) Synthesis of Complexes of the formula (II) or (IV)
A A mixture of the product obtained by the reaction of acylphenols and ethylene dioxide with acetyl nickel is refluxed in a lower alcohol. The resulting precipitates are purified in a conventional manner.
The details of these synthetic procedures are described in the references cited above.
Examples of the synthesis of the complexes used in this invention are illustrated below.
SYNTHESIS EXAMPLE 1
Synthesis of Compound 1-1 In 130 ml of methanol is dissolved 2 g of sodium hydroxide. Then 14.5 g of 2-lauroyl-5methylphenol is added to the methanol solution and dissolved therein completely. The solution obtained is added gradually to an aqueous solution formed by dissolving 12 g of nickel chloride hexahydrate in 100 ml water and the light green precipitates formed were recovered by filtration, washed with water and air-dried.
The precipitates have the following structure;
To 5 g of the dry nickel complex thus obtained is added 100 ml of concentrated aqueous ammonia and the mixture is stirred for 72 hours at room temperature, whereby red-brown precipitates form. The precipitates are recovered by filtration, washed with water, air-dried and recrystallized from benzene to provide 3 g of the red crystals of the desired compound.
SYNTHESIS EXAMPLE 2
Synthesis of Compound 1-33 In 26 ml of ethanol is dissolved 3.06 g of 2-hydroxy-4-methylphenylundecylketooxine obtained by the reaction of 2-lauroyl-5-methylphenol and hydroxylamine sulfate and the solution is refluxed. To the solution is added dropwise 7 ml of a solution of 1.10 g of nickel chloride hexahydrate gradually. After the dropwise addition is over, the solution is concentrated to remove the solvent and the dark green solid material thus obtained is recrystallized from benzene. Thus, 2.4 g of the fine crystals of Compound 1-33 are obtained.

While the mechanism whereby the complex of the present invention improves light fastness is not entirely clear, it is believed that upon exposure to light the organic substrate (dye image) is excited to a triplet state whereupon the complex interacts with the excited dye to absorb the high energy and thus restore the dye to its original state. Alternatively, oxygen may be excited upon exposure to a singlet state in which case the complex absorbs the high energy of the' excited oxygen and restores the oxygen to its original state. In any case the complex of the present invention effectively improves the light fastness of the organic substrate.
As described above, the metal complexes are used in this invention for stabilizing the organic substrate materials. These compounds may be incorporated in one or more silver halide emulsion layers of a color photographic material. Also, these compounds may be incorporated in a layer included in the non-sensitive portion of color photographic transfer materials. The complexes can be supplied for stabilizing photographic images by incorporation into the hydrophilic colloids constituting the photographic layers of a photographic element.The complexes are incorporated as a solution thereof in an organic solvent having low boiling point or an organic solvent miscible with water which does not adversely influence the photographic properties of the#photographic layers, such as, for example, an alcohol (e.g., methanol, ethanol, isopropanol, butanol, etc.) an ether (e.g., dimethyl ether, ethyl methyl ether, diethyl ether, 1 -ethoxypropane, etc.), a glycol (e.g., 1 ,2-ethanediol, 1 ,2-propanediol, 1,3- propanediol, etc.), a ketone (e.g., acetone, ethyl methyl ketone, 3-pentanone, etc.), an ester (e.g., ethyl formate, methyl acetate, ethyl acetate, etc.), an amide (e.g., formamide, acetamide, succinamide, etc.), and the like. It is desirable that the complex be incorporated before coating, such as when producing silver halide photographic emulsions, when forming an emulsified dispersion of couplers, or when preparing photographic coating compositions.
In order to introduce these complexes into hydrophilic colloids constituting photographic layers, methods usually employed for dispersing couplers in the color photographic fields may be employed. In this regard, U.S. Patents 2,304,939 and 2,322,027 disclose the use of high boiling organic solvents for dissolving these materials. Other applicable methods are described in U.S. Patents 2,801,170, 2,801,171 and 2,949,360, wherein low boiling or water-soluble organic solvents are used together with high boiling organic solvents.
Examples of the high boiling organic solvents which are effective for dispersing the substrate material and metal complexes in this invention are di-n-butyl phthalate, benzyl phthalate, triphenyl phosphate, tri-o-cresyl phosphate, di-phenyl-mono-p-tert-butylphenyl phosphate, monophenyl-di-ptert-butylphenyl phosphate, diphenyl-mono-o-chlorophenyl phosphate, monophenyl-di-o-chlorophenyl phosphate, 2,4-di-n-amylphenol, 2,4-di-t-amylphenol, N,N-diethyllaurylamide as well as trioctyl phosphate and trihexyl phosphate described in U.S. Patent 3,676,137.
The low boiling or water-soluble organic solvents which can be advantageously used together with these high boiling organic solvents are disclosed in, for example, U.S. Patents 2,801,171, 2,801,170 and 2,949,360.
These organic solvents include:
(1) low boiling organic solvents substantially immiscible in water, such as, for example, methyl acetate, ethyl acetate, propyl acetate, butyl acetate, isopropyl acetate, ethyl propionate, sec-butyl alcohol, ethyl formate, nitromethane, nitroethane, carbon tetrachloride, chloroform, etc., and
(2) water-miscible organic solvents such as, for example, methyl isobutyl ketone, #-ethoxyethyI acetate, P-butoxytetrahydrofu rfuryl adipate, diethylene glycol monoacetate, methoxytriglycol acetate, acetonylacetone, diacetone alcohol, ethylene glycol, acetone, methanol, ethanol, acetonitrile, dimethylformamide, dioxane, etc.
In general, the complex of the formula (I) is dissolved or suspended in an appropriate solvent which is chosen depending upon the physical properties of the complex used from water, watermiscible and water-immiscible organic and inorganic solvents (the details of which are described in U.S.
Patent 3,966,468) and the organic substrate material is dissolved or suspended therein. Alternatively, again depending upon the physical properties of the compounds, solutions and/or dispersions may be prepared separately and subsequently mixed. For example, a fluorescent whitening agent may be dissolved or suspended in an organic or inorganic solvent such as water or dimethyl formamide, etc., together with the complex of the present invention or separately; and the mixture may be coated onto or incorporated into a suitable base substance. An adjacent double layer coating is possible and in some cases may be preferred if some diffusion between the contiguous layers occurs and light fastness improvement is effected.
The present invention can also be used to improve the light fastness of a colored polymer. A
colored polymer is a polymer containing a coloring material in a state of molecular dispersion or melt.
The polymer is represented by natural resins other than gelatin, e.g., cellulose and derivatives thereof,
vinyl resins, polycondensates, silicone resins, alkyd resins, polyamides, paraffin and mineral waxes as
described in U.S. Patent 3,966,468. Where it is desired to improve the light fastness in a colored polymerfor use of agricultural vinyl sheets, the colored polymer and complex of the formula (I) are
likewise mixed in the form of a solution, dispersion, etc., followed by extrusion molding, etc., in a
conventional manner.
In the case of a photogrpahic material, the substrate material (the dye image) and the complex each may be present in one or more of the hydrophilic colloid layer making up a photographic element
(e.g., a film, paper, diffusion transfer unit, etc.). It is preferred that the metal chelate complex and the organic substrate material may be present (i.e., coexist) in the same emulsion layer, of course, the effect of the present invention can also be attained when the complex and substrate are present in contiguous
layers and diffusion occurs between the layers. Where undesirable diffusion occurs, conventional
mordanting techniques could be applied to the present invention.
In the case of incorporating the complex into a silver halide emulsion layer, the complex can be
incorporated into each emulsion layer making up the photographic element. In this case, the total
amount of complex present is in the range set forth below. The complex and substrate may be present in
non-light-sensitive elements or layers such as the dye image-receiving layer used in diffusion transfer film units. In the case of image transfer units, the metal chelate complex is preferably located in the
layer in which the dye images are finally found, i.e., in an image-receiving layer. Usually, the dye images formed in the image-receiving layer do not diffuse further into any other layer(s) so that the complex is easily maintained in the vicinity of the dye.When the organic substrate material and the complex are incorporated in such a non-photosensitive image-recording or image-receiving element, they are
mordanted. The complex contains a ligand capable of retaining it in the mordant layer of the image
receiving element so that it does not diffuse away from the dye stabilized thereby.
A number of types of image transfer film units are particularly appropriate for the practice of the present invention; One is the imbibition transfer film unit set fourth in U.S. Patent 2,882,1 56. The present invention can be further used in conjunction with the color image transfer film unit described in
U.S. Patents 2,087,817,3,185,567, 2,983,606,3,253,915, 3,227,550,3,227,551, 3,227,552, 3,415,646,3,594,164 and 3,594,165 and Belgian Patents 757,959 and 757,960.
The organic substrate materials and the complexes used in the practice of this invention can be used together with the materials as described in Pro duct Licensing Index, Vol. 92, No. 9232, 107-110 (1971, December) according to the manner as described therein.
Any amount of the complex will bring about some improvement in the light fastness of the organic substrate and theoretically there is no upper limit for the amount of the complex. Preferably, the complex is present in an amount of at least 0.1 mol% based on 1 mol of the organic substrate material, more preferably in an amount of 0.1 to 1,000 mol%, and most preferably in an amount of 1 to 300 mol%. In the case of a photographic material, the amount is often expressed in terms of a weight unit per square meter of photographic material which can be calculated from the parameters set out above.
In the case of a photographic material, the complex is preferably present in an amount of at least 1 micromole per square meter of the photogrpahic material, and more preferably in an amount of from about 10 to 1 x 104 micromoles per square meter of the material. The concentration of the substrate material corresponds in general to that for the image forming material usually adopted in color photographic technology. As is well known to those skilled in the art, the substrate material is preferably present in the range of from about 10 to 104 micromoles per square meter of the photographic material.
A more preferable range is from about 100 to about 3 x 103 micromoles per square meter of the photographic product.
The organic substrate material used in this invention generally has a maximum absorption peak in the wavelength region less than about 800 nm. However, the organic substrate material having the maximum absorption peak in the region of from about 300 nm to about 800 nm is preferred and the organic substrate material having the maximum absorption peak in the range of from about 400 nm to about 800 nm is most preferred.
In photographic materials based on this invention, any material ordinarily used as the supports for photographic materials may be used as the support therefor in this invention. Examples thereof are cellulose nitrate films, cellulose acetate films, cellulose acetate butyrate films, cellulose acetate propionate films, polystyrene films, polyethylene terephthalate films, polycarbonate films, laminated sheets of these films, and papers. Also, baryta-coated papers, papers coated with a-olefin polymer, in particular, a polymer of an a-olefin having 2 to 10 carbon atoms, such as polyethylene, polypropylene, etc., and plastic films the surface of which have been roughened to improve their adhesion to other polymers as shown in Japanese Patent Publication No. 1 9,068/72 are preferably used as the supports for photographic materials.
In photographic materials used in the method of this invention various hydrophilic colloids are used. Examples of the hydrophilic colloids used as the binders for photogrpahic silver halide emulsions and/or other coating compositions for photographic layers are gelatin; colloidal albumin; casein; cellulose derivatives such as carboxymethyl cellulose, hydroxyethyl cellulose, etc.; sugar derivatives such as agar, sodium alginate, starch derivatives, etc.; synthetic hydrophilic colloids such as polyvinyl alcohol, poly-N-vinylpyrrolidone, polyacrylic acid copolymers, maleic anhydride copolymers, polyacrylamide, and the derivatives or partially hydrolyzed products thereof. If necessary, a mixture of two or more of these colloids which are compatible with each other may be used.
Among the aforesaid materials, gelatin is most generally used but gelatin may be replaced partially or wholly with a synthetic polymer. Furthermore, so-called gelatin derivatives, that is, gelatin modified by treatment with an amino group, an imino group, a hydroxy group, a carboxy group, etc., contained in the gelatin molecule as a functional group with a reagent having a functional group which can react with these groups or graft gelatin having bonded thereto the molecular chain of another polymer may be used in place of gelatin.
The silver halide photographic emulsion layers or other photogrpahic layers of photographic materials used in this invention may further contain synthetic polymers such as, for example, waterdispersed vinyl polymers in the form of a latex, in particular, a compound or compounds capable of increasing the dimensional stability of the photographic materials solely or together with a hydrophilic water-permeable colloid.
The silver halide photogrpahic emulsion used in the method of this invention is usually prepared by mixing an aqueous solution of a water-soluble silver salt (e.g., silver nitrate) and an aqueous solution of a water-soluble halogen salt (e.g., potassium bromide) in the presence of a water soluble polymer solution such as an aqueous solution of gelatin. As such a silver halide, there is silver chloride, silver bromide as well as mixed si!ver halides such as silver chlorobromide, silver chloroiodide, silver chloroiodobromide, etc. These silver halide grians may be prepared according to a known or conventional processes. As a matter of course, they may be advantageously prepared using the socalled single jet method or double jet method or the controlled double jet method. Also, two or more different silver halide emulsions prepared separately may be used in mixture.
The above-mentioned silver halide photographic emulsions may further contain various compounds for preventing a reduction in sensitivity and the formation of fog during production, preservation or processing of the photographic material. As examples of such compounds, there are 4 hydroxy-6-methyl-1 ,3,3a,7-tetrnzaindene, 3-methylbenzothiazole, 1 -phenyl-5-mercaptotetrazole as well as many heterocyclic compounds, mercury-containing compounds, mercapto compounds, metal salts, etc.
The silver halide emulsions used in this invention may also be chemically sensitized in a conventional manner. As examples of chemical sensitizers used for the purpose, there are gold compounds such as an aurichlorate, gold trichloride, etc.; salts of noble metals such as platinum, palladium, iridium, and rhodium; sulfur compounds capable of forming silver sulfide by causing reaction with a silver salt, such as sodium thiosulfate, etc.; stannous salts, amines; and other reducing materials.
The silver halide photogrpahic emulsions used in this invention may, if necessary, be subjected to a spectral sensitization or super dye sensitization using cyanine dyes such as cyanine, merocyanine, carbocyanine, etc., solely or as a combination thereof or using a combination of the cyanine dye or dyes and styryl dyes. These dyes are properly selected according to the objects and use of the photographic materials, such as the wavelength region and sensitivity to be stabilized.
The hydrophilic colloid layers of photographic materials used in the method of this invention can be, if necessary, hardened by various cross-linking agents, for example, aldehyde series compounds, active halogen compounds, vinylsulfone compounds, carbodiimide compounds, N-methylol compounds, epoxy compounds, etc.
In applying the method of this invention to color photographic materials, after image exposure, the color photographic material may be processed in a conventional manner to form color images. The main processing steps in such case are color development, bleach, and fix and, if necessary, other steps such as washing and stabilization. In these steps, two or more steps may be performed in one step as blix step. The color development is usually performed in an alkaline solution containing an aromatic primary amine developing agent. Preferred examples of the aromatic primary amine developing agent are the compounds shown by formulae (A) to (L) described above.
In applying the method of this invention to color photographic materials, wherein the color photographic material is a color photographic diffusion transfer film unit, the processing of the photographic material is carried out automatically in the photogrpahic material. In this case, a color developer containing a color developing agent is contained in a rupturable container. As the developing agent, N-methylaminophenol, 1 -phenyl-3-pyrazolidone, 1 -phenyl-4,4-dimethyl-3-pyrazolidone, 1 - phenyl-4-methylhydroxymethyl-3-pyrazolidone, 3-methoxy-N,N-diethyl-p-phenylenediamine, etc., in addition to the compounds shown by formulae (A) to (L) above are suitable.
For forming color images in photographic materials based on this invention, various known methods can be used, such as the coupling reaction of the above-described dye-forming color couplers and the oxidation products of a p-phenylenediamine series color developing agent; development with a dye developer; the oxidation cleaveage reaction of DRR compounds; the dye-releasing reaction upon coupling of DDR couplers; the dye-forming reaction upon coupling reaction of DDR couplers and a silver dye bleaching process.
Accordingly, this invention can be applied to various kinds of color photographic materials such as color positive films, color papers, color negative films, color reversal films, color diffusion transfer film units, silver dye bleaching photographic materials, etc.
The following examples are provided for further understanding of the method of this invention.
They are not to be construed as limiting.
EXAMPLE 1
In a mixture of 3 ml of tricresyl phosphate and 5 ml of ethyl acetate was dissolved 0.1 g of 1 (2,4,6-trichlorophenyl)-3-(2-ch loro-5-tetradeca nam ido)anilino-4-j4-(N-ethyl-N-#- methanesulfonamidoethyl)aminophenyl imino j-5-oxo-2-pyrazoline and the solution was dispersed by emulsification in 10 g of an aqueous 10% gelatin solution containing 1 ml of an aqueous solution of 1% sodium dodecylbenzenesulfonate. Then, the emulsified dispersion was mixed with 10 g of an aqueous 10% gelatin solution and the mixture was coated on a paper support having coated on the both surfaces polyethylene to provide Sample A.
Also, Sample B was prepared in the same manner as the case of preparing Sample A except that 30 mg of Compound 1-1 of this invention was added when preparing the above-described emulsified dispersion and Sample C and Sample D were prepared by the same manner as the case of preparing
Sample A except that 1 5 mg or 150 mg of 2,5-di-tert-octylhydroquinone known as light fading preventing agent for dye was added at the case of preparing the emulsified dispersion. The amount of the dye thus coated was 60 mg/m2 in each sample. The amounts of the light fading preventing agent correspond to 18 mg/m2 for compound 1-1, 9 mg/m2 for 15 mg of the hydroquinone and 90 mg/m2 for 150 mg of the hydroquinone.These samples A-D were subjected to a fading test for 48 hours by a xenone tester of 200,000 lux illumination using an ultraviolet cut filter C-40, made by Fuji Photo Film
Co., Ltd. The results are shown in Table I.
TABLE I.
Density after

C 0.81 0.23
D 0.79 0.41
The measurement was made by means of a Macbeth Densitometer RD 514 using a Status AA green filter ("Status" is a registered Trade Mark). It has been confirmed that fading of Sample B containing Compound I-i of this invention is very small as compared with the other samples and, in particular, Sample C and Sample D show almost no effect for fade prevention in spite of the fact that they contain di-tert-octylhydroquinone in an amount equimolar to and 10 mole times the amount of Compound in Sample A. The result shows that Compound 1-1 of this invention has an astonishing effect for the prevention of light fading of a dye.
EXAMPLE 2
In a mixture of 0.2 ml of 1 N sodium hydroxide solution and 2 ml of methanol was dissolved 0.1 g of Compound Veil~2 and the solution was added to 10 g of an aqueous 10% gelatin solution. The mixture was coated on a paper support having coated on both surfaces polyethylene at a coverage of
Compound Vlll--2 of 80 mg/m2 to provide Sample E.
Also, Sample F was prepared by the same manner as the case of preparing Sample E except that a solution of 40 mg of Compound 1-33 (corresponding to a coating rate of 32 mg/m2) in 2 ml of methanol was added directly before coating and further Sample G was prepared as comparison sample by the same manner as the case of preparing Sample E except that 20 mg of 2,5-di-tertoctylhydroquinone (corresponding to a coating rate of 1 6 mg/m2), a known light fade preventing agent for dye was added. These samples were subjected to a fading test for 12 hours using a ultraviolet absorption filter as in Example 1. The results are shown in Table II.

The measurement was performed by a Macbeth densitometer as in Example 1. From the experimental result, it is understood that Compound 1-33 of this invention shows a very high light fading prevention effect.
EXAMPLE 3
In a mixture of 30 ml of tricresyl phosphate, 5 ml of dimethylformamide, and 15 ml of ethyl acetate was dissolved 10 g of a magenta coupler, 1 -(2,4,4-trichlorophenyl)-3-((2-chloro-5- tetradecanamido)anilino}-2-pyrazoiin-5-on and the solution was dispersed by emulsification on 80 g of an aqueous 10% gelatin solution containing 8 ml of an aqueous solution of 1% sodium dodecylbenzenesulfonate.
Then, the emulsified dispersion was mixed with 145 g of a green-sensitive silver chlorobromide emulsion (50 mole% Br, containing 7 g of Ag) and after adding thereto sodium dodecyl benzenesulfonate as a coating aid, the resultant mixture was coated on a paper support having coated on both surfaces thereof polyethylene at a coverage of the coupler of 400 mg/m2 to provide Sample H.
Also, Sample I was prepared by the same manner as in the case of preparing Sample Y except that 2.5 g of Compound 11-3 of this invention (corresponding to a coating rate of 100 mg/m2) was added at the preparation of the emulsified dispersion and further Sample J was prepared by the same manner as the case of preparing Sample H except that 1.0 g of 2,5-di-tert-octylhydroquinone (corresponding to a coating rate of 25 mg/m2) was added.These samples were exposed for 1 second at 1000 lux and processed by the following processing compositions:

Each sample having color images thus formed was expose#dtosun light for 2 weeks using
Ultraviolet Absorption Filter C-40 (made by Fuji Photo Film Co., Ltd.) cutting wave lengths shorter than400 nm. The results are shown in Table Ill. The measurement was performed by means of a Macbeth
Densitometer RD~514 (using a Status AA filter; "Status" is a registered Trade Mark) and the density change of the portion that the initial density was 2.0 was measured.

From the above result, it is understood that Compound 11-3 of this invention is an effective fading prevention agent.
EXAMPLE 4
A solution of 1 5 mg of a dye having the structure below and 500 mg of polycarbonate, Lexan 145 ("Lexan" is a registered Trae mark; manufactured by General Electric Co., Ltd.) in 100 ml of dichloromethane was coated onto a glass plate using a spinner. A magenta-colored film of 5.5,u thickness was thus prepared as Sample K.
In a similar manner, a colored film was prepared as Sample L except that Compound 1-51 were further incorporated into the solution.
The coating rate of the dye and the fade prevention compounds were 500 mg/m2 and 50 mg/m2, respectively.
The thus obtained films were exposed to sunlight for one month and a color fading test was carried out. The results are shown in Table IV below, in which density was mesaured at 550 nm.
TABLE IV.
Density after

L 1.0 0.92
It can be clearly seen from the results that Sample L containing the Chelate complex of the present invention provides a superior light fastness, even after the one month fading test, to Sample K containing no compound of the invention.
EXAMPLE 5
In a manner similar to Example 3, Sample M (Same as Sample H) as prepared.
Also, Sample N was prepared by the same manner as the case of preparing Sample I except that 2.0 g of Compound 1-51 of this invention was added at the preparation of the emulsified despersion and further Sample 0 was prepared by the same manner as the case of preparing Sample M (i.e.,
Sample H) except that 0.20 g of Compound IV (for comparison) described in U.S. Patent 4,050,938 issued to Smith Jr., et al., having the formula below, was added.
These samples were exposed for 1 second at 1000 lux and processed and then exposed to sunlight in a manner similar to Example 3.
Then, the measurement was performed by means of Macbeth Densitometer Rid~514 (using
Status AA filter) and the density change of the portion that the initial density was 1.0 was measured.
TABLE V.

As can be clearly seen from the data above, Sample 0 containing the known fade prevention compound shows a poor effect in preventing for fading color, further accompanied by a marked drop in relative photogrpahic speed by 1/100. Compound 1-51 of this invention is a very effective fade prevention agent without substantially reducing the photographic speed, which is surprising.
