Definitions
- the present invention refers to a light-sensitive silver halide color photographic multilayer material, in at least one blue light-sensitive layer associated with yellow dye forming couplers containing the combination of two different DIR (Development Inhibitor Releasing) couplers capable of releasing a development inhibiting compound upon reaction with the developing agent oxidation product.
- DIR Development Inhibitor Releasing
- Light-sensitive color photographic materials which make use of the substractive process for color reproduction, are known to comprise silver halide emulsion layers which are selectively sensitive to blue light, green light and red light and are associated with yellow dye, magenta dye and cyan dye forming couplers which (upon reaction with a primary amine type oxidized color developing agent) form complementary colors.
- an acylacetanilide type coupler is used to form a yellow colored image
- a pyrazolone, pyrazolotriazole, cyanacetophenone or indazolone type coupler is used to form a magenta colored image
- a phenolic, such as phenole or naphthole, type coupler is used to form a cyan colored image.
- a light-sensitive color photographic material in general comprises a blue-sensitive silver halide emulsion layer (or layers) which contains a yellow coupler and is mainly sensitive to blue light (substantially to wavelengths lower than about 500 nm), a green-sensitive silver halide emulsion layer (or layers) which contains a magenta coupler and is mainly sensitive to green light (substantially to wavelengths between about 500 and 600 nm) and a red- sensitive silver halide emulsion layer (or layers) which contains a cyan coupler and is mainly sensitive to red light (substantially to wavelengths higher than about 590 nm).
- DIR couplers which have a group with development inhibiting properties when it is released by the coupler itself. These groups are introduced into the coupling position of the coupler. Examples of DIR couplers are described by C.R. Barr, J.R. Thirtle and P.W. Wittum, Photographic Science and Eng., vol. 13, pp. 74-80 (1969) and ibid. pp.
- DIR couplers The purpose of DIR couplers is that of reducing granularity and improving image sharpness through intralayer or intraimage effects (i.e. within the same layer or the same colored image) and improving color reproduction through interlayer or interimage effects (i.e., within different layers or different colored images).
- intralayer or intraimage effects i.e. within the same layer or the same colored image
- interlayer or interimage effects i.e., within different layers or different colored images

- US 5,006,452 on the contrary describes a color photographic material containing a DIR coupler having a 4,7-dihalogen-2-benzotriazolyl type group which is released during development upon oxidation with a developer agent.
- US 5,332,656 describes a color photographic material containing the combination of a) a yellow dye forming diketomethylene coupler in its active coupling position having a 4,7-dihalogen-2-benzotriazolyl group which provides a compound having development inhibiting properties when the group is released from the active coupling position upon color development reaction, and b) a yellow dye forming alkoxybenzoyl-acetanilide coupler having a releasable 3-hydantoine group linked to the active coupling position.
- An object of the present invention is that of obtaining, for medium and low speed films, a higher inhibition action given by DIR couplers to obtain a reduced granularity, above all in low density regions where the granularity problems are more severe, and a higher color purity. It is another object of the present invention that of obtaining better interimage effects, but at the same time reducing to the minimum the sensitivity decrease in all layers.
