Abstract
The present invention relates to a silver halide photographic material, particularly to a silver halide colourized photographic paper which comprises a supporter and emulsion layers. The material is characterized in that in a blue sensitive emulsion layer existing on the supporter, fine particles whose average particle diameter is 0.55 mum are adopted; in a green sensitive emulsion layer existing on the supporter, the composition of pyrazolo triazole magenta coupler whose structure is showed in formula 3, a discolouration preventing agent whose structure is showed in formula 4 and an ultraviolet radiation absorbing agent whose structure is showed in formula 5 is adopted; in formula 3, R1 refers to a hydrogen atom, a methyl radical or a butyl, R2 refers to a C1 to C5 alkyl, and R3 refers to a C10 to C20 long-chain radical comprising an aryl group or a five-membered or six-membered heterocycle containing sulfur and nitrogen; in formula 4, R4 refers to a hydroxy, a phenoxy group or a six-membered ring containing a sulfonic group and a nitrogen atom, and R5 refers to a hydrogen atom, a C10 to C20 alkyl, a hydroxy or an aryl group; in formula 5, R6, R7 and R8 refer to phenolic groups. The silver halide colourized photographic paper has the advantages of favorable colour rendition performance, light stability of images and liquid medicine quality of fatigue resistance.

Nowadays, in the photographic silver halide system, tend to adopt a kind of technology that is referred to as the high sense of particulate, also promptly when guaranteeing suitable light sensitivity, reduce the size of silver emulsion particle, so that picture is more clear, finer and smoother, still as far as possible, after the silver halide particle size reduced, a greatest problem of existence was exactly how to improve its light sensitivity.Described in U.S. Pat 6610467,6555308,5888704,6335154, can pass through to change particle shape, as make the T particle, improve the absorption and the efficiency of light absorption of dyestuff, thereby improve light sensitivity; Some precious metal ions that also can mix in emulsion reduce the compounding machine meeting in light induced electron and hole, thereby improve light sensitivity.
In photographic silver halide material, the uncle's aromatic amine developing agent colour development of exposure back, developer oxide that forms and colour coupler coupling form dyestuff, obtain image, wherein pinkish red image is formed by colour couplers such as pyrazolone, pyrazolo benzimidazole and pyrazolo nitrogen azoles, and wherein pyrazolone-type is a most widely used magenta colour coupler of initial stage; Compare with pyrazolone type master magenta colour coupler, the dyestuff that pyrazolo nitrogen azoles type master magenta colour coupler forms has better spectral absorption curve, in 430nm～assorted absorption in 450nm sense blue area, long wave one side absorption peak is steeper, therefore has better colour reproduction, and have advantages such as color development rate height, anti-formaldehyde ability are strong, therefore since the nineties external autochromy paper product mostly adopt pyrazolo nitrogen azoles type magenta colour coupler.
Chinese patent CN1258021 discloses a kind of use and has comprised also [5,1-c]-1,2 of novel pyrazole, the photographic material of 4-triazole type magenta colour coupler, and this photographic material has color rendition preferably and light stability.
Chinese patent CN1023217 discloses a kind of use 1H-pyrazolo [1,5-b]-1,2,4-triazole magenta colour coupler or pyrazolo [5,1-c]-1,2, the photographic material of 4-triazole magenta colour coupler, this photographic material color rendition is good, and is all showing good photography characteristic aspect light sensitivity, level and the colour density.
Chinese patent CN1258860 discloses a kind of photographic material, and be combined with ring-type azole colour coupler dyestuff and the stabiliser compositions that comprises following compound in its emulsion layer: (1) first compound molecule general formula is: (R

10Can adopt polytype substituting group, different substituting groups have a significant impact photographic property.U.S. Pat 4942117, all disclosing among Jap.P. JP4-204645, JP10-161284, the JP6-250357 and having adopted substituting group is the pyrazoloazoles colour coupler of aryl, such colour coupler coupling activity is higher, the dyestuff that forms is fast light, heat-resisting, moisture-proof improves a lot, and absorption peak is narrower; The pyrazoloazole coupler magenta colour coupler that adopts among U.S. Pat 4822730, the US5234805 contains sulfonamide; Disclosed pyrazoloazoles colour coupler contains carboxyl among U.S. Pat 4835094, the Jap.P. JP10-161285, and colour coupler has higher color development density, and its dyestuff also has stronger stability, and is too inresponsive to the pH value of developer solution; Have on disclosed pyrazoloazoles colour coupler α-C in U.S. Pat 5183728, US5681691, the European patent EP 779543-the N-substituted alkyl, make dyestuff the absorption red shift 5～12 nanometers.
When being exposed in light, heat or the moisture by colour coupler and the formed image of developer coupling, dye molecule easily intensifies, and plays pendulum, and the compound that becomes colorless after oxidation or the hydrolysis causes the image phenomenon of fading.This embodies more obviously on the dyestuff that magenta colour coupler forms, especially pyrazolo azole magenta colour coupler.The measure that prevents or eliminate this photofading mainly contains: adopt more stable colour coupler (introducing fade-proof group in colour coupler), use anti-fading agent, ultraviolet absorber etc.
The colour coupler that contains hexa-atomic nitrogen heterocyclic ring structures such as substituted-piperazinyl is disclosed among Jap.P. JP5-241288, the JP11-109577; Jap.P. JP10-186603 proposes to contain-SO in the molecular structure
2-(N-L-OH)
2Pyrazolo nitrogen azoles magenta colour coupler, these colour couplers have improved the photostability of dyestuff.
Eliminating the effective measures of photofading and be colour coupler and anti-fading agent and ultraviolet absorber is used in combination.Anti-fading agent can capture light shine the creating singlet oxygen by using of generation down or the radical anion of oxygen, prevents that dyestuff is oxidized, plays fade-proof effect; Ultraviolet absorber then can prevent the oxidative decomposition that dyestuff takes place under the ultraviolet ray irradiation.The anti-fading agent that uses mainly contains phenols, chroman class, two spiral shell indenes class, aryl oxide class, phosphoramide types etc.Ultraviolet absorber mainly contains Benzotriazole Type, propylene aldehydes, s-triazine type etc.U.S. Pat 5236819, US5082766, German patent DE 4307194 disclose uses specific stabilizing agent and pyrazoloazole coupler colour coupler to make up the stability of improving dyestuff, but effect and unsatisfactory; U.S. Pat 5561037 discloses comprehensive use aromatic sulfonamides and ring-type sulfonamide stabilizing agent as the fade-proof stabilizing agent of pyrazoloazole coupler colour coupler, plays better effects, but this aromatic sulfonamides preparation difficulty, and cost is higher; Chinese patent CN1258860 discloses the yellow acid amides of use combination of stabilizers benzene, aryl oxide is obtained better anti-fading effect.
