Definitions

  • This invention relates to filter dyes and their use in photographic elements.
  • Filter dyes are widely used in photographic elements. Filter dyes may be located in several locations in an element. They may be in a radiation-­sensitive layer, an overcoat layer, in a layer adjacent to the radiation-sensitive layer, in an interlayer of a multilayer element, in an undercoat layer adjacent to the support or in a backing layer on the side of the support opposite the radiation-­sensitive layer.
  • the filter dye When incorporated directly in the radiation-­sensitive layer they can function to improve sharpness by absorbing light scattered from one silver halide grain to another. Such dyes are referred to as absorber dyes. Filter dyes also func­tion to retard the sensitivity of one light sensitive layer relative to another in a multilayer element. By absorbing some of the exposing radiation the filter dye aids in balancing the sensitivities of all the light sensitive layers.
  • Filter dyes that function primarily to ab­sorb unwanted radiation due to reflection or refrac­tion from layer interfaces, the layer-support inter­face, and particularly from the back side of the support, are referred to as antihalation dyes.
  • the layers that contain them are referred to as anti­halation layers.
  • filter layer may be used in or near the overcoat layer to protect the light sensitive layer against radiation from certain spectral regions.
  • a filter layer may be used in or near the overcoat layer to protect the light sensitive layer against radiation from certain spectral regions.
  • filter dye interlayers In multilayer films where there may be two or more light sensitive layers, it is sometimes necessary to have filter dye interlayers.
  • duplitized® materials such as X-ray films, filter layers are used to reduce crossover exposure of the light sensitive layers. Elimination of crossover exposure is an ideal that is highly desirable but has not yet been fully attained.
  • a number of problems are associated with filter dyes and filter layers. It is very important that the dyes remain in the layer and not wander or diffuse into the adjacent layers. This often necessitates the presence of a mordant to hold the dye in the layer. It is equally important for the dyes to be completely decolorized and/or removed from the element, usually during processing, after they have performed their function. Dye stability, especially under high temperature and high humidity incubation is also important.
  • U.S. Patent 3,560,214 discloses dyes com­prising a carboxyl and phenyl substituted pyrazoline nucleus linked through a methine group to a dialkyl­aminophenyl group.
  • these dyes according to the patent and our own experiments, are migratory.
  • A represents a substituted or unsubstituted nucleus having a carboxyphenyl or sulfonamidophenyl substituent selected from the group consisting of 2-pryazolin-5-ones free of any substituent bonded thereto through a carboxyl group, rhodanines, hydantoins, 2-thiohydantoins, 4-thiohydantoins, 2,4-oxazolidindiones, 2-thio-2,4-oxazolidindiones, isoxazolinones, barbiturics, 2-thiobarbiturics, and indandiones, R represents hydrogen, substituted or unsubsti­tuted alkyl of 1 to 4 carbon atoms, or benzyl, R1 and R2 each independently represents substituted or unsubstituted alkyl or aryl, or taken together with R5, R6, N, and the carbon atoms
  • the dyes of the invention are merostyryl arylidenes having the formula: wherein R represents hydrogen, substituted or unsubstituted alkyl of 1 to 4 carbon atoms, or benzyl, R1 and R2 each independently represents substituted or unsubstituted alkyl or aryl, or taken together with R5, R6, N, and the carbon atoms to whatever they are attached, represent the atoms needed to complete a julolydyl ring, R3 and R7 each independently represents H, substituted or unsubstituted alkyl, aryl, alkoxy, hydrogen, or acetamido, R4 represents substituted or unsubstituted alkyl, alkoxycarbonyl, aryl, acyl, or amido, R5 and R6 each independently represents H, or R5 taken together with R1, or R6 taken together with R2, represent the atoms necessary to complete a carbocyclic ring, R8 is CO2H or NHS
  • the carboxyphenyl substituent on A is im­portant in immobilizing the dye at coating pH's of 5-7.
  • the acyl, alkyl and alkoxy groups may contain from one to twenty carbons. Examples of such groups include acetyl, benzoyl, methyl, ethyl, propyl, methoxy carboxyl, ethoxy carboxyl, butoxy­carboxyl, fluoralkyl, dodecyl, and octadecyl.
  • the aryl groups may contain from six to twenty carbons, which may be further substituted with a wide variety of groups. Examples of such substituted and unsubstituted aryl groups including phenyl and napthyl with alkyl substituents as defined above.
  • Microcrystalline dispersions of the dyes of this invention leave no residual post-processing stain in processed photographic elements.
  • Polymeric mordants are not needed to immobilize the dyes, as immobilization is achieved without mordants.
  • Complete and irreversible dye removal during processing is achieved.
  • Broadened and shifted ab­sorption is obtained which makes the compositions particularly suitable for filter or antihalation applications.
  • Their broadened absorption bands are particularly useful in reducing the number of dyes needed in a single element to absorb unwanted radia­tion. Another advantage is superior dye stability when subjected to high temperature and high humidity incubation.
  • Examples 1-3 below relate to the preparation of representative dyes of the invention. Variations on the procedures described to obtain other dyes of this invention, such as those of the examples and Table I and II below are within the skill of the practicing synthetic chemist. Procedures for making such dyes are described in "The Cyanine Dyes and Related Compounds" , Frances Hamer, Interscience Publishers, 1984.
  • NMR nuclear magnetic resonance
  • IR infrared
  • HCl hydrochloric acid
  • EtOH ethanol
  • MeOH methanol
  • Et2O ethyl ether
  • DMF dimethylformamide
  • DMSO dimethylsulfoxide
  • the dyes prepared in Examples 1-3 and other dyes of the invention prepared with similar proper­ties are listed in Tables I and II along with their absorption maxima (in methanol solution with a sta­bilizing amount of triethylamine) and extinction coefficients.
  • the dyes of this invention are useful in, for example, black and white, single color, multicolor, or duplitized® X-ray photographic elements. They can be present in any layer of the element where it is desirable to include a filter dye, for example, in the silver halide emulsion layer or a separate filter layer.
  • the dyes of the invention can be utilized in any amount that is useful to filter or absorb light, but it is particularly advantageous to utilize them in an amount and in a location so that they will be solubilized and washed out during processing. In situations where it is desirable to absorb only a small amount of light, only a small amount of dye is needed.
  • the dye is preferably present in the element of the invention in an amount of from 1 to 1000 mg/ft2.
  • the dyes of the invention are preferably in the form of a solid particle microcrystalline dispersion for incorporation into a layer such as a hydrophilic colloid layer coated on a photographic element.
  • the microcrystalline dispersion can be formed by precipitating the dye in the form of a dispersion and/or by well-known milling techniques, e.g., ball-milling, sand-milling, or colloid-milling the dye in the presence of a dispersing agent.
  • the dye particles in the dispersion preferably have a mean diameter of less than 10 ⁇ m and more preferably of less than 1 ⁇ m.
  • the dye particles can be conveniently prepared in sizes ranging down to 0.01 ⁇ m or less.
  • Multicolor elements contain dye image-­forming units sensitive to each of the three primary regions of the spectrum.
  • Each unit can be comprised of a single emulsion layer or of multiple emulsion layers sensitive to a given region of the spectrum.
  • the layers of the element, including the layers of the image-forming units, can be arranged in various orders as known in the art.
  • the emulsions sensitive to each of the three primary regions of the spectrum can be disposed as a single segmented layer, e.g., as by the use of micro-­vessels as described in U.S. Patent 4,362,806.
  • a typical multicolor photographic element would comprise a support bearing a cyan dye image-­forming unit comprised of at least one red-sensitive silver halide emulsion layer having associated there­with at least one cyan dye-forming coupler, a magenta dye image-forming unit comprising at least one green-sensitive silver halide emulsion layer having associated therewith at least one magenta dye-forming coupler and a yellow dye image-forming unit compris­ing at least one blue-sensitive silver halide emul­sion layer having associated therewith at least one yellow dye-forming coupler.
  • the element can contain additional layers, other filter layers, interlayers, overcoat layers, subbing layers, and the like.
  • the silver halide emulsions employed can be either negative-working or positive-working. Suit­able emulsions and their preparation are described in Research Disclosure Sections I and II and the published cations cited therein. Suitable vehicles for the emulsion layers and other layers are described in Research Disclosure Section IX and the publications cited therein.
  • the elements can include additional couplers as described in Research Disclosure Section VII, paragraphs D, E, F and G and the publications cited therein. These couplers can be incorporated in the elements and emulsions as described in Research Disclosure Section VII, para­graph C and the publications cited therein.
  • the photographic elements or individual layers thereof can contain brighteners (see Research Disclosure Section V), antifoggants and stabilizers (see Research Disclosure Section VI), antistain agents and image dye stabilizer (see Research Disclosure Section VII, paragraphs I and J), light absorbing and scattering materials (see Research Disclosure Section VIII), hardeners (see Research Disclosure Section XI), plasticizers and lubricants (see Research Disclosure Section XII), antistatic agents (see Research Disclosure Section XIII), mat­ting agents (see Research Disclosure Section XVI) and development modifiers (see Research Disclosure Sec­tion XXI).
  • the photographic elements can be coated on a variety of supports as described in Research Disclosure Section XVII and the references described therein.
  • Photographic elements can be exposed to ac­tinic radiation, typically in the visible region of the spectrum, to form a latent image as described in Research Disclosure Section XVIII and then processed to form a visible dye image as described in Research Disclosure Section XIX.
  • Processing to form a visible dye image includes the step of contacting the element with a color developing agent to reduce developable silver halide and oxidize the color developing agent. Oxidized color developing agent in turn reacts with the coupler to yield a dye.
  • the dyes were subjected to ball-milling according to the following procedure. Water (21.7 ml) and a 6.7% solution of Triton X-200® sufactant (TX-200®) (2.65 g) (available from Rohm & Haas) were placed in a 60 ml screw-capped bottle. A 1.00 g sample of dye was added to this solution. Zirconium oxide (ZrO) beads (40 ml) (2mm diameter) were added and the container with the cap tightly secured was placed in a mill and the contents were milled for four days. The container was removed and the contents added to a 12.5% aqueous gelatin (8.0 g). The new mixture was placed on a roller mill for 10 minutes to reduce foaming and the resulting mixture was then filtered to remove the ZrO beads.
  • ZrO Zirconium oxide
  • a spreading agent, surfactant 10G®, and a hardener bis(vinyl-sulfonylmethyl)ether
  • a melt prepared from the latter mixture was then coated on polyethylene terephthalate support to achieve a dye coverage of 0.32 g/m2, gelatin coverage of 1.60 g/m2, a spreading agent level of 0.096 g/m2 and a hardener level of 0.016 g/m2.
  • Spectral data were obtained from an analysis of the coatings on a spectrophotometer interfaced with a computer. A summary of the data obtained is in Table III where the dye numbers correspond to those of Tables I and II.
  • HBW half band width
  • microcrystalline dispersions of the dyes of the invention are suitable for filter applications where broad visible light filtration is required. This broad absorption also serves to reduce the number of dyes needed for a particular filter application.
  • the coated microcrystalline dye dispersions prepared as described in the previous examples were evaluated for dye mobility. Samples of the coatings were given a five minute distilled water wash. The results for four of the dyes, 1, 2, 3 and 5, are shown in Table IV. The coatings were also evaluated for post processing stain following processing in the Kodak Prostar® processor used commercially to process microfilm, subjecting the elements to a development step at a pH of 11.4 for 30 seconds. These results are also included in Table IV.
  • Table IV shows that no dye density was lost by the dyes dispersed and coated as described in the previous examples due to the distilled water wash. This shows that there was no dye wandering from layer to layer.
  • the comparison dye on the other hand, exhibited severe washout, indicating a high degree of dye wandering.
  • Table IV also demonstrates dramatically the complete removal of the microcrystalline dispersion dyes on Prostar® processing at room temperature. No residual stain is left. The same results were observed when the coatings were processed with Kodak X-Omat® processing, which is used commercially to process x-ray film, subjecting the elements to a development step at a pH of 10.3 for 30 seconds. This is an improvement over other known latex imbibed yellow filter dyes which are incompletely removed by these processing conditions.
  • Dye 25 had a ⁇ -max of 449 nm and a bandwidth of 121 nm before washing or processing.
  • Dye 26 had a ⁇ -max of 453 nm and a bandwidth of 97 nm before washing or processing.
  • Table V indicate that the photographic compositions of the invention containing Dyes 25 and 26 do not wander during the water wash, but decolorize completely after photographic processing.
  • microcrystalline dyes of this invention in combination of other dyes, is illustrated with dyes 1 and 5 of Table I.
  • the dispersions were prepared as in examples 5-19. These dispersions were each coated as a component of an antihalation layer in a multilayer format, along with a cyan filter dye, bis[1-(4-carboxyphenyl)-3-methyl-2-pyrazolin-5-one-­(4)]pentamethineoxonol.
  • the coatings, 1 to 4 in Table VI were evaluated for dye stain after processing.
  • the emulsion layer was a chemically and spectrally sensitized 0.25 micron cubic silver bromoiodide (3% iodide) emulsion layer coated to achieve silver coverage of 1.45 g/m2 and gelatin coverage of 1.56 g/m2.
  • the gelatin coverage in the antihalation layer was 1.88 g/m2.
  • the levels of dyes 1 and 5 and of the cyan dye are indicated in Table VI.
  • the gelatin coverage in the overcoat layer was 1.56 g/m2.
  • the coatings were exposed to a tungsten light source in a sensitometer, developed, fixed and washed in the Kodak Prostar® process and dried.
