Embodiment 1

[0021] The coating of the cyan color-forming layer includes two layers, the first layer is a red-sensitive silver halide emulsion layer, and the second layer is a cyan color-forming coating solution:

[0022]

Embodiment 2

[0024] The coating of the cyan color-forming layer includes two layers, the first layer is a red-sensitive silver halide emulsion layer, and the second layer is a cyan color-forming coating solution:

[0025]

[0026] The photographic materials formed by coating Comparative Example, Example 1 and Example 2 were tested for their relative photosensitive properties. The results are shown in the table below:

[0027]

[0028] From figure 1 As can be seen from the above table, embodiment 1 and embodiment 2 are similar to the comparative example in terms of absorption peaks, and the coating amount of embodiment 1 and embodiment 2 silver halide is less than that of the comparative example, and the photographs of embodiment 1 and embodiment 2 The absorption range of the material in the color development curve is larger than that of the comparative example, so the color expression is more abundant, the coating density is also significantly greater than that of the comparative ex...

Abstract

The invention discloses cyan color-forming coating liquid used in color photographic paper and the color photographic paper formed by using the same. The cyan color-forming coating liquid is preparedfrom the following components in percentage by weight: 4 to 7 percent of 2-(4-t-butyl)phenyl-6-cyano-5-[bis(ethoxycarboxymethyl)carbamoyloxy]-1H-pyrrolo[1,2-b][1,2,4]triazole-7-methylcyclohexyl-2,6-bis-t-butyl-4-carboxylate and 1.5 to 3 percent of 2-[2,4-bis(1,1-dimethylpropyl)phenoxy]-N-(3,5-dichloro-4-ethyl-2-hydroxyphenyl)butyrylamide. The range of the absorption wavelength of the cyan color development curve of a coating can be expanded to 600nm to 650nm.

Description

technical field [0001] The invention relates to a photosensitive photographic material, especially a cyan color-forming coating liquid used in color photographic paper and the color photographic paper thereof. Background technique [0002] Since the 21st century, digital imaging technology and products have continued to develop rapidly, and digital imaging has penetrated into various fields such as industry, military, medical, printing, commercial advertising, photographic art, and mass consumption. Digital imaging technology and products have become the mainstream of the imaging equipment market. With the development of digital imaging technology, products and markets, the classification and varieties of photographic photosensitive materials have undergone great changes. [0003] Currently Kodak, Fuji and Lucky each have their own technologies, production lines and marketing systems. Kodak, with its natural performance of color, Fuji, with its excellent whiteness and exce...
