Problems solved by technology

However, such conventional print-making color photographic light-sensitive materials have a disadvantage that the dyes formed by a color development from the respective couplers used, particularly the magenta dye and the cyan dye are poor in the resistance to light, tends to be discolored by light with time, and become out of color balance after being discolored.
However, there still exists another disadvantage that the light-sensitive material, after being processed, loses as time goes by the gloss on the surface thereof by light, heat, moisture, and the like; i.e., the so-called sweat phenomenon arises, thus deteriorating the image quality.

example 1

A light-sensitive material was prepared having the component layers as given in Table 1.

TABLE 1 Coated Coated amt. Coated amt. of UV of Ag amt. of absorbing Layer (mg / gelatin agent Coup- No. Layer dm.sup.2) (mg / dm.sup.2) (mg / dm.sup.2) ler Layer 6 Protective -- 15 0 or 4.0 -- layer Layer 5 Red- 3.0 20 -- (C-1) sensitive *EM layer Layer 4 2nd -- 15 UV-7S 4.0 -- interlayer Layer 3 Green- 3.0 20 -- (M-1) sensitive EM layer Layer 2 1st -- 15 -- -- interlayer Layer 1 Blue- 4.0 20 -- (Y-1) sensitive EM layer Polyethylene-coated paper support *EM represents "emulsion"

The kind of the ultraviolet absorbing agent and the kind and amount of the high-boiling organic solvent used in the protective layer and the second interlayer were varied as shown in Table 2, thereby preparing nine samples.

In addition, the structures of the used yellow coupler Y-1, magenta coupler M-1 and cyan coupler C-1 are as indicated below. And in Table 2, the "DBP" represents dibutyl phthalate and the "DOP" represents di...

A light-sensitive material was prepared having the component layers as shown in Table 5.

TABLE 5 Coated Coated amt. Coated amt. of UV of Ag amt. of absorbing Layer (mg / gelatin agent Coup- No. Layer dm.sup.2) (mg / dm.sup.2) (mg / dm.sup.2) ler Layer 7 Protective -- 10 -- -- layer Layer 6 3rd -- 10 4.0 -- interlayer Layer 5 Red- 3.0 20 -- C-2 sensitive EM layer Layer 4 2nd -- 15 4.0 -- interlayer Layer 3 Green- 3.0 20 -- M-2 sensitive EM layer Layer 2 1st -- 15 -- -- interlayer Layer 1 Blue- 4.0 20 -- Y-2 sensitive EM layer Polyethylene-coated paper support

The structures of the used couplers Y-2, M-2 and C-2 are as shown below. And in the second layer the UV-7S and UV-4S were used in the proportion of 1:1. ##STR14##

In the above layer composition, the kind of the ultraviolet absorbing agent and the kind and amount of the high-boiling organic solvent used in the third interlayer were varied as given in Table 6, whereby samples No. 1 to No. 5 were prepared.

Abstract

A color photographic light-sensitive material comprising a reflective support having thereon a plurality of silver halide emulsion layers of which the emulsion layer located farthest from said support has, on each of both the support side thereof and the uppermost side at least one nonlight-sensitive layer containing an effective amount of an ultraviolet absorbing agent, said ultraviolet absorbing agent being used in said nonlight-sensitive layer on the uppermost side of said emulsion layer being a 2-(2'-hydroxyphenyl)benzotriazole-type compound which is in the liquid form at normal room temperature.

Description

BACKGROUND OF THE INVENTION1. Field of the InventionThe present invention relates particularly to a color photographic light-sensitive material for use in making photographic prints.2. Prior Art and the Problems ThereofConventionally color photographic light-sensitive materials for use in making photographic prints are generally formed by coating in order on a reflective support an yellow coupler-containing blue-sensitive silver halide emulsion layer, nonlight-sensitive first interlayer, magenta coupler-containing green-sensitive silver halide emulsion layer, nonlight-sensitive second interlayer, cyan coupler-containing red-sensitive silver halide emulsion layer and nonlight-sensitive protective layer.And particularly in order to prevent the discoloration by ultraviolet rays of the dyes formed by a color development from the respective couplers, an ultraviolet absorbing agent is added to the second interlayer.However, such conventional print-making color photographic light-sensitive...
