Abstract

PURPOSE:To form a yellow image with superior resistance to light, moisture, heat, etc. without causion fog by adding a yellow coupler having a thiazolidinedione group to a photographic silver halide emulsion or a color developer. CONSTITUTION:A coupler represented by formula I (where A is a residue obtd. by removing a hydrogen atom from the active methylene group of a yellow coupler, and each of R1 and R2 is H, alkyl, aryl, aralkyl, benzylidene or cycloalkyl) is prepd. For example, a compound represented by formula II or III is used as the coupler. The coupler is added to a photographic silver halide emulsion or a color developer, and bleach fixing is carried out immediately after color development to form the desired yellow image. The coupler is obtd. by halogenating a yellow coupler having active methylene and by reacting the halogenated coupler with 2,4-dioxothiazolidine (deriv.).

The present invention relates to a method for forming a yellow image on a color photographic material, and more particularly to a method for forming a yellow dye image on a color photographic material using a novel two-equivalent yellow dye image-forming coupler. Moreover, it is a color printing medium that receives Tltf and m-wave energy sources such as ultraviolet light, visible light, related to yellow dye image forming methods). Photographic process 1: After exposure of a photographic royalty containing a coupler, color development is performed using a developer containing an aromatic primary amine developer as a crude drug to form a dye image. Among the couplers used in this wrestling, yellow couplers have active methylene groups that serve to couple with the oxidation products of aromatic primary amine developing agents to form yellow dyes. When this active methylene chloride is unsubstituted, four molecules of silver halide are required to form one molecule of dye during color development. In other words, it is a so-called 4-equivalent coupler. However, even from a coupler in which one of the water flux atoms of the active methylene is substituted with a halogen atom such as the JIJ! These couplers are called 2-equivalent couplers because of the ability to form 2-equivalent couplers.2-equivalent couplers have the following advantages over 4-equivalent couplers: (1) Conventionally known 4-equivalent couplers. Coupling speed is improved compared to couplers (Stone) (2) To obtain the same coloring dye...silver halide requires only half a scratch, so costs can be reduced. (3) The emulsion layer can be made thinner, The resolution and sharpness of color images are improved. (4) In the case of multiple layers, the light transmission to the lower layer is improved and the photographic sensitivity is improved. It would be very advantageous to form color images in multilayer color photosensitive materials.Such two-equivalent couplers contain the active methylene hydrogen atom of the yellow image-forming coupler, which contains active methylene bonded to two carbonyl groups. One of the components is substituted, and this substituted component is removed during color development yL concentration.
- It has the property of However, some 2-equivalent couplers tend to cause color stains such as fog, and some have development-inhibiting properties; however, the 2-equivalent couplers used in the present invention are colorless and have high reactivity. It has a natural property and almost no contamination is observed. In addition, the present invention does not require temperature control (yellow dye obtained from the yellow coupler used by the above-mentioned color development &r.
It has excellent resistance to heat, excellent long-term durability, no unnecessary absorption in the long wavelength region, and shows sharp absorption with little absorption in the surrounding light1,2, and has an extremely favorable hue in terms of color reproduction. The 1゛Z) coupler used in the present invention is a two-equivalent force dollar expressed by the following general formula.
