Definitions
- This invention relates to color photography and particularly to color-forming coupler compounds containing a m-alkylphenoxyacylgroup.
- a colored image may beproduced by adding to certain developer solutions or by incorporating in the gelatino silver-halide emulsion, a compound which couples during development with the oxidation products of the developing agent to form a colored substance which is deposited close to the silver grains of the silver image during development.
- a compound which is employed in conjunction with a developing agent for the exposed silver-halide and which couples with the oxidation product of said developing agent during development, is referred to herein .as a coupling component or coupler.
- a coupler In order to be of use in color photography, a coupler must produce. a dye image of suitable stability and spectral' characteristics. In addition to the above properties, a coupler must be capable of being incorporated in a photographic emulsion. and be fast to diffusion. Thus, couplers may be incorporated. in a photographic emulsion by dispersing therein a solution of said coupler in an oily water-immiscible solvent such as tricresyl phosphate, dibutyl phthalate, and. the like. Alternately, couplers may be employed that are alkali soluble and, therefore, can be dissolved directly in the photographic emulsion. In order to render the couplers fast to.
- an oily water-immiscible solvent such as tricresyl phosphate, dibutyl phthalate, and. the like.
- couplers may be employed that are alkali soluble and, therefore, can be dissolved directly in the photographic emulsion. In order
- Another object is to provide a coupler having extremely high solubility in water-immiscible organic solvents.

Description
United States Patent 3,285,747- COLOR FORMERS CONTAINING A m-ALKYL- PHENOXYACYL GROUP Robert F. Coles, North St. Paul, Minn., assignor to General Analiue & Film Corporation, New York, N.Y., a corporation of Delaware No Drawing. Filed Aug. 26, 1964, Ser. No. 392,330 3 Claims. (Cl. 96100) This application is a continuation-impart of application Serial No. 681,884,- filed September 4, 1957, now abandoned.
This invention relates to color photography and particularly to color-forming coupler compounds containing a m-alkylphenoxyacylgroup.
' It is known that a colored image may beproduced by adding to certain developer solutions or by incorporating in the gelatino silver-halide emulsion, a compound which couples during development with the oxidation products of the developing agent to form a colored substance which is deposited close to the silver grains of the silver image during development. Such a compound, which is employed in conjunction with a developing agent for the exposed silver-halide and which couples with the oxidation product of said developing agent during development, is referred to herein .as a coupling component or coupler.
In order to be of use in color photography, a coupler must produce. a dye image of suitable stability and spectral' characteristics. In addition to the above properties, a coupler must be capable of being incorporated in a photographic emulsion. and be fast to diffusion. Thus, couplers may be incorporated. in a photographic emulsion by dispersing therein a solution of said coupler in an oily water-immiscible solvent such as tricresyl phosphate, dibutyl phthalate, and. the like. Alternately, couplers may be employed that are alkali soluble and, therefore, can be dissolved directly in the photographic emulsion. In order to render the couplers fast to. diffusion in the gelatino silver-halide emulsion, it is usual to introduce into the coupler molecule a. molecule enlarging group such as a long alkyl chain. Although the prior art contains numerous patents on color formers, very few of them possess the aforementioned properties which render them suitable for use in color photography.
It is, therefore, an object of this invention to provide a coupler characterized by improved fastness to diffusion in a photographic emulsion.
Another object is to provide a coupler having extremely high solubility in water-immiscible organic solvents.
A still further object of this invention is to provide color-forming components possessing relatively low meltingrpoints.
A still further object is to provide photographic emulsions containing color formers, characterized by extremely high solubility in water-immiscible organic solvents and low melting points.
Other objects and advantages of this invention will be apparent as the description proceeds.
The above objects are realized by incorporating into one of the usual color coupler molecules, i.e., a ketomethylene compound, a pyrazolone or a. phenol, am-alkylphenoxyacyl residue in which the alkyl radical contains at least carbon atoms. Thisgroup maybe readily introduced by conventional methods into color-forming moieties that contain a primary or secondary amino group, a reactive hydroxyl group or other suitable linkages. The coupling components thus obtained. are extremely soluble in water-immiscible organic solvents such as tricresyl phosphate, dibutyl phthalate, and the like and possess low melting points, generally 100 C. or lower. This property is highly desirable in a dispersed droplet type of color former and dye system, since it produces a system which hasonly a slight tendency toward crystallization. In fact, the aforesaid properties of highsolubility in organic solvents and low melting point make these couplers particularly suitable in mixed-grain type emulsions.
The color couplers contemplated herein can be represented by the following general formulae :1
wherein R is hydrogen, an alkyl group, i.e., methyl, ethyl, n-propyl, n-butyl, sec.-butyl, amyl", iso-amyl', hexyl, heptyl, etc.; R is a long chain alkyl group containing from 10 to 20 carbon: atoms, i.e., capryl, undecylyl, lauryl, myristyl, pentadecyl, palmityl, stearyl, etc; R 1 is a methyl group; R is hydrogen or an alkyl group as given above for R; A represents that part of the molecule that contains the coupling function such as. a reactive methylene or phenolic hydroxyl group capable of coupling with the oxidation products. of a primary aromatic amino color developing agent, and Y is Specific compounds which maybe used according to. this invention are the following:

On exposure and development of this emulsion with a developing solution employing Z-amino-S-diethylaminotoluene as the developing agent and subsequent removal of silver, a colored image was obtained.
Various photographic developing agents can be employed with the couplers of my invention. The primary aromatic amino developing agents are generally suitable including the phenylenediamines and aminophenols. The alkyl phenylenediamines may be substituted in the amino group as well as in the ring. Suitable compounds are 4-aminoaniline, 4-ethylaminoaniline, 2-diethylaminoaniline, 4-dialkylaminoaniline, e.g., 4-dimethylamin0aniline, 4 diethylaminoaniline, 4-[N-(fl-hydroxyethyD-N- ethyl]aminoaniline, 4 amino-N-ethyl-N-(fi-methanesulfonamidoethyl)-2-methylaniline sulfate, and the like. The above developing agents are preferably used in the form of their salts such as the hydrochloride or hydrosulfate as they are more soluble and stable than the free bases. All of these compounds have a primary amino group which enables the oxidation product of the developer to couple with the color compounds to form dye images. After removal of the silver image by bleaching and fixing in a manner well-known to the art, the color image remains in the emulsion.
A suitable developing solution can be prepared as follows:
G. 2-amino-5-diethylaminotoluene 2 Sodium carbonate (anhydrous) 20 Sodium sulfite (anhydrous) 2 Potassium bromide 0.2
Water to make 1 liter.
