Description

FIELD OF THE INVENTION

The present invention relates to a silver halide color photographic light-sensitive material, and more particularly, to a silver halide color photographic light-sensitive material excellent in light-fastness for color images thereon and further excellent in coloring property.

BACKGROUND OF THE INVENTION

In the field of a silver halide color photographic light-sensitive material, it is requested that dye images obtained from a coupler are stable against color changing and color fading even when they are exposed to light for a long time or stored under high temperature and high humidity conditions.

However, it is known that the above-mentioned dye images do not have sufficient stability mainly against UV rays or visible rays so that they are subject to color change and color fading when they are exposed to the above-mentioned actinic rays. In order to dissolve the above-mentioned problems, there have been proposed methods including one to choose various couplers with a property of less color fading property, one to use a UV absorber for protecting dye images from UV rays or one to introduce to a coupler a group providing light flatness.

However, in order to provide satisfactory light fastness to dye images by the use of a UV absorber, it is necessary to use UV absorbers in a relatively large amount. In such occasions, dye images were sometimes noticeably contaminated due to coloring of the UV absorber itself. In addition, a UV absorber does not work to prevent color fading of dye images caused by visible rays. In other words, there is a limitation in improving light fastness by a UV absorber.

In addition, methods to use a phenol hydroxyl group or an agents for preventing dye image fading having a group which generates, through hydrolysis, a phenol hydroxyl group are known. For example, Japanese Patent Publication Nos. 31256/1973, 31625/1973 and 30462/1976 and Japanese Patent Publication Open to Public Inspection (hereinafter referred to as Japanese Patent O.P.I. Publication) Nos. 134326/1974 and 134327/1974 propose methods to use a phenols and a bisphenols. U.S. Pat. No. 3,069,262 proposes a method to use pyrogallol and garlic acid and its esters, U.S. Pat. Nos. 2,360,290 and 4,015,990 propose methods to use a-tocopherols and its acyl derivatives, Japanese Patent Publication No. 27534/1977, Japanese Patent O.P.I. Publication No. 14751/1977, and U.S. Pat. No. 2,735,765 propose methods to use hydroquinone derivatives, U.S. Pat. Nos. 3,432,300 and 3,574,627 propose methods to use 6-hydroxychromans, U.S. Pat. No. 3,573,050 proposes a method to use 5-hydroxychroman derivatives and Japanese Patent Publication No. 20977/1974 proposes a method to use 6,6'-dihydroxy-2,2'-spirobichromans. However, the above-mentioned compounds do not show sufficient effects for preventing color fading or color changing of dyes, though they show the effects to some extent.

British Patent No. 1,451,000 discloses a method to improve stability of dye images against light by the use of azomethine extinction compounds whose absorption peak is more bathochromic compared with the peak of dye images. However, their influence on the hue of dye images is so noticeable and disadvantageous, because the azomethine extinction compounds themselves are colored.

Methods to stabilize dyes against light by the use of metal complexes are disclosed in Japanese Patent O.P.I. Publication No. 87649/1975 and Research Disclosure No. 15162 (1976). However, an amount capable of providing enough effects for preventing color fading cannot be added since these complexes have neither sufficient effects for preventing color fading nor high solubility on organic solvents. In addition, these complexes themselves are noticeably colored, so that they adversely affect the hue and purity of the dye images formed through color development processing, when a large amount of them are added.

SUMMARY OF THE INVENTION

The first object of the present invention is to provide a silver halide color photographic light-sensitive material wherein the spectral absorption characteristics of dye images formed therein is excellent and light fastness of the dye images has noticeably been improved.

Example 1

On a paper support, on one side of which polyethylene is laminated and the other side of which polyethylene containing titan ate oxide is laminated, photographic layers, of which compositions are given in Tables 1 and 2, were coated on the side where polyethylene containing titanate oxide is laminated, to prepare a multi-layered silver halide light-sensitive color photographic material, Sample 101.

To a mixture consisting of 26.7 g of yellow dye-forming coupler(Y-9, a yellow coupler disclosed in page 51 of JA OPI 4-313751), 10.0 g of dye image stabilizer(ST-1),6.6 g of dye image stabilizer(ST-2),0.6 g of anti-staining agent (HQ-1) and 6.67 g of high boiling point organic solvent (DNP), were dissolved by adding 60 ml of ethyl acetate. Then, this mixture was emulsified in 220 ml of 10% gelatin solution using a ultra-sonic homogenizer and thus an emulsion comprising a yellow dye-forming coupler was prepared.

It is apparent from Tables 3 and 4 that the light stability and the color forming property of the samples according to the present invention (Samples 105 through 110, and 105' through 110'), in which the compound of the present invention is used as a high boiling point organic solvent, have been greatly improved compared with Comparative Sample and the color forming property has also been improved. Moreover, the effect of sharpening of the absorption without changing the maximum absorption wave length was observed. In sample 102 for which HBS-1, which is phenol derivative, is used, some improvement in the light stability was observed, however, the effect was insufficient. In addition, undesirable effects of bathochromic shift and broadening of the absorption were also observed. Sample using a comparative HBS-3 results inferior color developing ability and broader absorption peak though it shows certain improvement of stability against light.

In Samples 111 through 120 and 115' through 120' HBS is used in an amount of three times to Samples 101 through 110 and so on. The compound of the present invention works much more effective when large amount thereof is used. The stability against light is improved and sharp absorption peak is obtained.

Example 2

In Example 1 a magenta coupler, HBS and dye stabilizer in the third layer of Sample 101 were replaced with those shown Table 5 to obtain Samples 200 through 214. The same test was conducted as in Example 1. The result is summarized in Table 5.

Samples using polyhydric alcohol of the invention as a HBS in combination with a magenta coupler M-8 which has a secondary alkyl group at 6th position show the improvement in stability against light. Samples containing increased amount of polyhydric alcohol of the invention (Samples 202, 204, 206, 208, 210, 212, and 214) show further improved stability to light.

In Example 1 HBS in the third layer of Sample 101 was replaced with those shown table 6 to obtain Samples 201' through 212'. The same test was conducted as in Example 1. The result is summarized in Table 6.

In the Example a part of amount of the polyhydric alcohol is replaced with a conventional high boiling solvent. Consequently the weight ratio of the polyhydric alcohol to a coupler is varied. The Table shows that the samples containing a polyhydric alcohol in an amount of more than 50 weight 50% to a coupler are more advantageous in the stability to light. Further samples containing no conventional HBS are much more effective.

In Example 1 HBS in the first layer of Sample 101 were replaced with those shown Table 7 to obtain Samples 302 through 311. The resulted samples were exposed wedgewise by blue light, and same developing process and test was conducted as in Example 1. The result is summarized in Table 7.
