40/ 55,636 flaims. (Cl. 9684) The present invention relates to color photography and more particularly to a color photographic light-sensitive element containing an ultraviolet absorber.
A color photographic image is generally inferior in light fastness to a black and white photographic image since the former is composed of dyes formed by color developments. It is natural to attempt to remove this drawback by eliminating ultraviolet rays having a large role in destroying the dyes by utilizing an ultraviolet absorber, and as a practical manner for using such an ultra violet absorber there have generally been adopted the following two methods. In the one method, a print or a transparent positive picture is, after development, coated or impregnated with an ultraviolet absorber while in the other method an ultraviolet absorber is preliminarily incorporated in a light-sensitive element at the production thereof such that the ultraviolet absorber is not washed out at development processing. From the users convenience the latter method is preferable and the instant invention is also concerned with the latter type.
The ultraviolet absorber to be employed for the purpose must be provided with the following properties:
(1) It absorbs effectively ultraviolet rays of 300-400 m in wave length but does not absorb visible rays of longer than 420 mu.
(2) It is not washed out or discolored by development processing.
(3) The ultraviolet absorber itself is not colored and the ultraviolet absorbing power thereof is not reduced by light exposure.
(4) It does not give a bad influence on the photographic light-sensitive element containing it at the preparation thereof, during preservation and at development.
Hitherto, various compounds have been known as ultraviolet absorbers, but a few of them satisfy the abovementioned four factors, that is, many ofjthe conventionally available ultraviolet absorbers are washed out during development. Several types of ultraviolet absorbers also atfect adversely the photographic characteristics of light-sensitive emulsions.
The inventors have found that the above-mentioned factors are satisfied When the 2-phenylimino-3-alkyl-5- pyridylmethylene thiazolidone compound shown by the general formula.
silver halide particles, that is, a light-sensitive silver halide layer or may be an intermediate layer or a protective layer containing no silver halide particles; Further, in
Patented Npv. 14, 1967 the light-sensitive element which will be exposed from the back side of the element, that is, from the support side as a transparent positive picture, the compound may be effectively incorporated in a subbing layer or a coating layer on the back side of the support. Moreover, if necessary, the compound in this invention may be incorporated in more than two coating layers. As these coating layers, a gelatin layer is most suitable, but the layer may contain other high molecular materials.
The typical examples of the compound included in the above-mentioned general formula to be used in this invention are shown below but it should be understood that the compounds to be used in this invention as ultraviolet absorbers should not be limited to these.

The use of a compound similar to the compound of this invention, that is, the use of 2-phenylimino-3-alkyl-5- benzalthiazolidone is disclosed in US. Patent 2,739,888,.
but the compound of this invention is superior to the a spectral distribution of energy and intensity simlar to those of a sun beam.

Percentage known compound in fastness to light. That is, as will be clear from the. experimental results shown below, only 510% of the. compound used in the present invention is decomposed under the same conditions by which 30% of the prior art compound is decomposed. It is a veryimportant factor that an ultraviolet absorber itself is stable to light exposure for a long period of time and hence the compound used in this invention can be considered to have novelty and utility.
It has been confirmed by the following experiment that the compound used in this invention is excellent as the ultraviolet absorber for color photographic light-sensitive elements.
Fifty grams. of any of above-illustrated Compounds 1-6 or the known ultraviolet absorber, 2-phenylimino-3- cetyl-S-benzalthiazolidone was added in 50 got dibutyl phthalate at a temperature not higher than 80 C. and the resulting solution was dispersed in a mixed solution of 1 kg. of a 10% gelatin solution and 100 g. of a 5% solution of sodium alkyl-benzene sulfonate in a colloid mill for minutes, whereby a uniform dispersion of the ultraviolet absorber having an average particle size of about 0.3 micron was obtained.
Thereafter, the dispersion was applied to a transparent film base of triacetyl cellulose and dried. From the thus prepared film, the extent of the washing-out of the com-.
pound was detected. The results are as follows:
layers but 14-0 mg, in particular, 3-2O mg. per 100 sq. cm. of the area of coating layer is suitable. Furthermore,
by the addition of the compound used in this invention, the preferable photographic properties of the photographic light-sensitive element are not reduced.
Example 1 A blue-sensitive silver, iodo-bromide emulsion containing a yellow coupler, 3,S-dicarboXy-a-(4-stearoylamidobenzoyl)acetanilide was applied to baryta paper. The
coupled had been added in the emulsion as an alkaline aqueous solution thereof. Thereafter, a green-sensitive silver chloro-bromide emulsion containing a magenta coupler, l (3-sulfo-3-phenoxyphenyl)-3-stearoyl-5-pyrazolone was applied to the thus formed emulsion layer and further a red-sensitive chloro-bromide emulsion containmg a cyan coupler, N-n-octadecyl-1-hydroxy-4-sulfo-2- naphthamide was applied on the layer. On the thus formed red-sensitive layer there was further coated a protective Reduction percent in transmission density (370 mp) T'une Comp. Comp. Comp. Comp. Comp.

Then, these samples were exposed to a xenon tester for about 20 hours and thereafter the decomposition percentages of the compounds were measured, the results of which are shown in table below. In addition, the xenon tester used in this experiment is a light source having FADING PERCENTAGE ,OF COLOR IMAGE,

When the ultraviolet absorber of this invention was incorporated in the intermediate layer between the first light-sensitive emulsion layer and the second light-sensitive emulsion layer instead of incorporating it in the protective layer, the fading of color images formed in the light-sensitive layers under the intermediate layer containing the ultraviolet absorber was prevented as anticipated. Further, almost the same results were obtained when a film base was used as the support instead of the 'baryta paper.
Example 2 The dispersion of the compound the same as in Example l was added in the first emulsion layer in Example 1, that is, in the red-sensitive silver chlorobromide emulsion layer. The content of the compound was 5 mg./100 sq. cm. The magenta layer of the second emulsion layer and the yellow layer of the third emulsion layer were as in Example 1.
The thus prepared multi-Iayer color photographic lightsensitive element was exposed and subjected to develop- :ment, water-washing, fixing, water-washing, bleach-fixing, water-washing, hardening, water-washing, and drying. Thereafter, the thus processed element was exposed to a xenon tester for 20 hours and the reduction in percentage of color image density was measured, the results of which are shown in the following table:
FADING PERCENTAGE OF COLOR IMAGE 6. The color photographic light-sensitive element according to claim 1 wherein said compound is 7. The color photographic light-sensitive element according to claim 1 wherein said compound is C=CH As clear from the experimental results the ultraviolet prevention effect could be obtained also in the case of incorporating the dispersion of the compound of this invention directly in a silver halide emulsion.
Further, in the case where the ultraviolet absorber was incorporated in a photographic light-sensitive emulsion layer, the photographic properties of the photographic light-sensitive emulsion was not infected by the compound.
