Definitions
- This invention relates to 4-sulfonamido-substituted twoequivalent phenolor ot-naphthol-type cyan dye-forming couplers.
- Color photographic images are obtained in the photographic art by coupling a silver image development byproduct (i.e., oxidized aromatic primary amino developing agents) with a color-forming coupler compound.
- a silver image development byproduct i.e., oxidized aromatic primary amino developing agents
- the subtractive process of color formation is ordinarily employed and the resulting cyan, magenta or yellow image dyes are complementary to the primary colors.
- Coupler compounds employed to produce cyan photographic dyes for instance, generally contain phenolic or u-naphtholic moieties.
- Such phenolic or a-naphtholie couplers usually have various substituent groups on the ring which are capable of affecting various physical characteristics of the compound.
- Heavy substituent groups may act as ballasting groups and tend to decrease solubility in aqueous alkaline processing compositions while increasing non-diffusible characteristics of a coupler in the hydrophilic layers of photo-elements during processing; the corresponding introduction of substituent groups such as halo or alkyl elsewhere on the same ring, however, may adversely or beneficially change the light stability of the image dye produced upon exposure and color development.

United States Patent 3,737,316 TWO-EQUIVALENT SULFONAMIDO COUPLERS Ilmari Fritiof Salminen and Anthony Loria, Rochester,
NAIRI glssignors to Eastman Kodak Company, Rochester, N0 Drawing. Filed Aug. 31, 1971, Ser. No. 176,684 Int. Cl. G03c 7/00 US. Cl. 96-566 28 Claims ABSTRACT OF THE DISCLOSURE 4-sulfonamido-substituted two-equivalent phenolor anaphthol-type cyan dye-forming photographic couplers in color developing compositions, in color photographic silver halide emulsion compositions; elements having such emulsion compositions coated thereon, and processes utilizing such elements.
This invention relates to 4-sulfonamido-substituted twoequivalent phenolor ot-naphthol-type cyan dye-forming couplers.
Color photographic images are obtained in the photographic art by coupling a silver image development byproduct (i.e., oxidized aromatic primary amino developing agents) with a color-forming coupler compound. The subtractive process of color formation is ordinarily employed and the resulting cyan, magenta or yellow image dyes are complementary to the primary colors. Coupler compounds employed to produce cyan photographic dyes, for instance, generally contain phenolic or u-naphtholic moieties.
Such phenolic or a-naphtholie couplers usually have various substituent groups on the ring which are capable of affecting various physical characteristics of the compound. Heavy substituent groups, for instance, may act as ballasting groups and tend to decrease solubility in aqueous alkaline processing compositions while increasing non-diffusible characteristics of a coupler in the hydrophilic layers of photo-elements during processing; the corresponding introduction of substituent groups such as halo or alkyl elsewhere on the same ring, however, may adversely or beneficially change the light stability of the image dye produced upon exposure and color development. The presence of an acylamido group on the ring may affect heat stability of some compounds, while the D value of a photographic image dye is sometimes increased by substitution of various other groups onto the No. 2 position on the aromatic nucleus. The abovedescribed changes are obviously not uniformly predictable or necessarily beneficial for all color photographic purposes.
In a color photographic system the color-forming coupler may be the unballasted or diifusible type which is conveniently introduced as part of the developing solution, or of the non-difiusible ballasted type which is initially incorporated into or contiguous with a light-sensitive photographic silver halide emulsion layer, both types being made available to react with oxidized color developing agent as a function of silver halide development to obtain a substantially non-ditlusible image dye.
Conventional color-forming coupler compounds of the phenolic or a-naphtholic configuration have an active CH= group at the No. 4 ring position which reacts with oxidized color developer, as indicated above, to produce an indoaniline dye. Dye-forming color photographic couplers of the above types are known and described as four-equivalent couplers, and are characterized in requiring the development of four light-exposed silver halide molecules in order to produce one molecule of dye.
Non-diifusible couplers of the four-equivalent type are ice exemplified, for instance, in US. Pats. 2,895,826, 2,474,- 293 and 2,908,573. Known diffusible (i.e., unballasted or lightly ballasted) couplers are conveniently exemplified in US. Pats. 2,113,329, 2,252,718 and 3,002,836.
Two-equivalent dye-forming couplers of the diffusible and, non-diffusible types are functionally characterized by requiring the development of only two exposed silver halide molecules during development to obtain one molecule of dye. Such couplers are generally derived from corresponding four-equivalent couplers of either difiusible or non-ditlusible types by replacing an available H atom in a coupling position (e.g., No. 4 ring position of a phenol or a-naphthol ring of a cyan dye-forming coupler) with a nonchromophoric coupling 011 group such as a fluorine atom, a chlorine atom, an acyloxy group, an aryloxy, an alkoxy, an arylthio, a cyclooxy group or a thiocyano group.
Both two-equivalent and four-equivalent type couplers of the water-soluble (i.e., Fischer type) and non-watersoluble types are utilized for present day color photographic purposes since the combination of characteristics required by modern technology may vary widely.
By way of example, it is important to obtain thinner, more durable photographic elements containing stable couplers which, in turn, produce lightand heat-stable photographic dyes having precise spectral absorption characteristics. The quality of the photographic image, for instance, depends to a large extent upon the relative solubility of certain coupler compounds in highand/or low-boiling organic solvents as described and utilized, for instance, in Julian, U.S. Pat. 2,949,360, in the light of earlier disclosures in Mannes, US. Pat. 2,304,939; Jelley et al., US. Pat. 2,322,827; Vittum, U.S. Pat. 2,801,170; and Fierke, US. Pat. 2,801,171. The use of minimal amounts of coupler solvent is desirable since the bulk, durability and optical opacity of the resulting photographic element is directly correlated to the amount of solvent employed and retained. This, in turn, affects image definition and resolution properties of the element.
Of equal importance is the need for non-difiusible couplers which may be homogeneously incorporated into silver halide emulsions in carefully controlled amounts without adversely affecting viscosity, adhesion, or the unity of any particular emulsion layer during modern high speed multilayer application onto a film backing. Undesired changes in viscosity of melted gelatin photographic emulsions may be caused by additives such as wetting agents, color components, type of gelatin, etc., and these changes directly alfect the coating characteristics of a photographic emulsion.
Including antihalation and gelatin interlayers, up to eight or more separate layers may be applied to a film base to obtain a modern color photographic element [ref. Kirk-Othmer, Vol. 5, pp. 812-845, (1964), Encyclopedia of Chemical Technology]. For this reason, any major coupler-induced changes in the adhesion or coating characteristics of a photographic layer are unacceptable. This general problem is recognized, for instance, on page 250 of the text by Zelikman and Levi, entitled Making and Coating Photographic Emulsions, The Focal Press, (1964), and also in British Pat. 1,193,321.
To achieve the above-indicated beneficial characteristics and to avoid corresponding undesirable features for modern color photographic purposes, it is necessary to ascertain which particular group of substituents favor a minimal number of undesirable characteristics While, at the same time, encourage a pro-conceived spectrum of favorable characteristics.
It is known, for instance, from Us. Pat. 2,362,598 of Vittum et al. that some couplers having sulfonamido substituents on the ring tend to form dyes having deficient heat and light stability. Improvement has been obtained in such cases, however, by attaching the nitrogen atom of the sulfonamido group to the No. 5 or 6 carbon (i.e., noncoupling positions) of the phenolic or naphtholic ring.
In addition, the known difliculty in obtaining non-diffusible type azine dyes from certain ballasted (non-diffusible) couplers is partly resolved in accordance with U.S. Pat. 2,569,906 of Starke by incorporating two ballasted alkyl or aryl sulfonamido groups onto a phenolic or aniline ring, the No. 4 position (coupling position) of the ring being specifically excluded from such substitution.
'From U.S. Pat. 2,53 6,010 of Schmidt et al., it is ascertained that phenolic-type couplers do not readily form azine dye images (i.e., etfect ring closure) unless the phenol ring is substituted in the meta position with an alkyl or aryl sulfonamido group.
It is not apparent, from the above teaching, whether certain sulfonamido substituent groups in the No. 4 coupling position will (1) remain functionally active in a beneficial way, or
(2) will beneficially aifect heat and light stability of the resulting dye obtained from the two-equivalent coupler compound as compared with the corresponding fourequivalent coupler compound.
It is an object of the present invention to obtain a new group of cyan dye-producing coupler compounds, corresponding color photographic emulsions, developer solutions and color photographic elements containing such coupler compounds.
It is a further object to obtain new cyan dye-producing two-equivalent coupler compounds which are easily obtained and which additionally produce dyes having improved light and heat stability as compared with corresponding known four-equivalent couplers.
It is a still further object to achieve the above objects without corresponding loss in image definition or resolution characteristics of a photographic element or material utilizing the new coupler, and without effecting undesirable viscosity changes in a photographic emulsion containing such couplers prior to or during application onto a film base or emulsion support.
The above objects are accomplished, for instance, by
vutilizing a 4-sulfonamido-substituted phenolor a 4-sulfonamido-substituted a-naphthol-two-equivalent cyan dyeforming photographic coupler in which the amido moiety of the 4-sulfonamido substituent is attached to the No. 4 carbon atom of the phenol or u-naphthol ring. Such compounds can be used in a photographic color processing .composition, as well as in phtographic silver halide emulsions. This unique class of coupler compounds is conveniently described in the general formula wherein R SO --NH- preferably represents a nonchromophoric radical attached onto the No. 4 carbon of the phenolicor a-naphtholic-ring of COUP; and
R is an alkyl or an aryl group, inclusive of straight or branched alkyls of 1-20 carbon atoms, exemplified by methyl, isopropyl, octadecyl and eicosyl, also an aryl group such as a phenyl or a naphthyl radical and inclusive of phenyl, naphthyl, and substituted phenyl or substituted "naphthyl'having at least one ring substituent such as an -alkyl or alkoxy having alkyl moieties of 1-20 carbon atoms, also a ring substituent such as a nitro, a carboxy,

The ballasted non-difiusible type cyan couplers of the present invention are usefully incorporated into lightsensitive photographic silver halide emulsion layers and applied onto an emulsion support or film base in a singleor multi-layer color photographic material by known methods (example: the solvent and Fisher fat-tail methods) as described, for instance, in Mannes et al. in U.S. 2,304,939-40 and Jelley et al. in U.S. Pat. 2,322,027, in which high-boiling organic solvents are used to dissolve the coupler. Further useful procedures are described, for instance, in Vittum et a1. U.S. Pat. 2,801,170; Fierke ct al. US. Pat. 2,801,171 (July 1957); and Julian U.S. Pat. 2,479,360 (August 1960), whereby low-boiling or water-soluble organic solvents are used with or in place of a high-boiling solvent. In the case of multi-layer photographic materials or elements, the non-ditfusible coupler compounds are generally incorporated into the redsensitive silver halide emulsion layer and preferably utilize minimal amounts of high-boiling solvents.
Generally speaking, a useful coupler concentration will vary from about 25-200 mg./ft. of coated material, a range of 30-50 mg./ft. being generally satisfactory for use in photographic paper, with overlapping and higher concentrations found useful in color photographic films.
A variety of color coupler-containing photographic materials and elements are obtainable utilizing the above family of cyan dye-producing couplers. Generally speaking, however, such photographic materials and elements will comprise the following main components:
(A) A support layer such as cellulose nitrate film, cellulose acetate film, polyvinylacetal film, polystyrene film, poly( ethylene terephthalate) film, polyethylene film, polypropylene film and related films of resinous materials as well as paper, polyethylene coated paper, glass, and others. The terms include paper or other flexible fibrous material which can be partially acetylated or coated with baryta or some other hydrophobic film or surface which repels and does not absorb or adsorb Water. A support layer having a hydrophobic surface can also include hydrophobic resin layers Which have been subject to a corona treatment as described, for instance, in British Pats. 971,058, 1,060,526 and U.S. Pats. 2,864,755 and 2,864,756 to improve adhesion of hydrophilic colloid layers coated over them. Such resin layers or films may be either self-supporting or may be coated over another support layer. Specific supports ha'ving useful hydrophobic surfaces include polyethylene terephthalate films electronbombarded to have a contact angle less than 45 (U.S. Pat. 3,220,842), a corona-treated surface comprising a chromium halide (U.S. Pat. 3,117,865), or corona-treated hardened gelatin coated papers (Belgian Pat. 671,661), etc. The support layer may also contain various functional additives such as titanium dioxide, zinc oxide, and silica as suggested in U.S. Pats. 2,992,101 and 2,701,245, and anti-static agents as described, for instance, in U.S. Pat. 3,253,922;

The support is conveniently coated in succession with a red-sensitive layer containing one or more of the above-defined class of cyan-dye-producing coupler, a green-sensitive layer and a blue-sensitive layer, either with or without a Carey- Let filter layer between the blueand green-sensitive 12 layers. The three differently color-sensitized layers can also be arranged in any other order over one another that is desirable, with the exception that a Carey- Lea filter layer cannot be placed over a blue-sensitive layer.
The light-sensitive silver halide emulsions can include coarse, regular, or fine grain silver halide crystals or mixtures thereof such as silver chloride, silver bromide, silver bromoiodide, silver chlorobromide, silver chloroiodide, silver chlorobromoiodide and mixtures thereof; such emulsions are described, for instance, in The Photographic Journal, volume LXXIX, May 1939, pages 330-338; Journal of Photographic Science, volume 12, No. 5, Sept./ Oct. 1964, pages 242-251, and also in U.S. Pats. 2,184,013, 2,456,953, 2,541,472, 2,563,785, 3,367,778 and 3,501,307. In addition to the cyan-dye-forming couplers of the present invention such emulsions used in greenand blue-sensitive layers can include twoand four-equivalent magentaand yellow-dye-producing couplers of the type described, for instance, in U.S. Pats. 2,453,661, 2,449,966, 2,521,908, 2,908,573, 3,311,476, 3,476,563, 3,152,896 and 3,062,653.
