Description

[Detailed description of the invention]

The present invention relates to a silver halide photosensitive material provided with a photographic constituent layer containing a polymer having a photographically useful group at the qL position. In general, each of the constituent layers of a silver halide photosensitive side diagonal contains 41 (photographic additives), and these photographically useful compounds, especially hydrophobic compounds, are added to the f41 aqueous colloidal solution or dispersion that forms the layer. Many methods are known for dispersing the compound in a liquid. For example, dissolving the hydrophobic compound in a high boiling point solvent,
A method of dispersing this solution in a hydrophilic colloid solution or dispersion, or bathing a hydrophobic compound in an organic solvent that can be mixed with water, gradually mixing an aqueous polymer latexne into this solution, There is a method of filling latex particles with a compound and then dispersing it in a hydrophilic colloid solution or dispersion. However, if, for example, a color coupler or the like is used as a hydrophobic compound in the former option, a high-energy emulsification and dispersion process is required, and furthermore, deterioration of the color coupler etc. may occur during the emulsification and dispersion process. In many cases, this is not the preferred method. On the other hand, in the latter method, it is necessary to limit the amount of the hydrophobic compound added in order to prevent agglomeration of latex particles, and therefore there is a problem that desirable photographic properties cannot necessarily be obtained. Furthermore, in addition to the above-mentioned method, a method of dispersing a hydrophobic compound by treating it with a hydrophilic polymer compound is also widely known. When the hydrophobic compound is Color Cub 2-, for example, British Patent No. 880,206, British Patent No. 967.503,

No. 7 and other specifications describe examples of polymer coupler latexes. However, in the case of the above-mentioned hydrophilic polymer coupler, if it is incorporated into a dispersion medium such as gelatin and then processed using an alkaline developer, the polymer coupler will diffuse into the processing solution. Moreover, in the case of the polymer coupler latex mentioned above, it has the disadvantage that the reactivity with the developing agent is not necessarily good. Therefore, as a means to prevent such hydrophilic polymer couplers from diffusing into the processing liquid, a method has been proposed in which the couplers are immobilized by forming crosslinks with gelatin, which is a dispersion medium. For example, Research Disclosure No. 17825,
No. 18735, U.S. Patent No. 4,207,109,
Same No. 4,215,195 and No. 4,247,67
The polymer coupler disclosed in the specification of No. 3 and the like is a hydrophilic and functional polymer coupler that forms a crosslink with gelatin via a hardening agent. However, as a photographically useful hydrophobic compound according to the present invention, for example, a polymerizable vinyl monomer with a color coupler is hydrophobic, and if the polymer coupler as a whole is not made hydrophilic, The proportion of the polymerizable vinyl monomer having a color coupler in the color coupler is limited to a fairly low level. Therefore, in order to obtain a dye image with a high density and crystalline quality using such a polymer coupler, a considerably large amount of additive is required, and this may affect, for example, the thickness of the constituent layers of the photosensitive material. This is not a good idea because it also affects image characteristics, such as image sharpness and quality saving. Therefore, the first object of the present invention is to provide a hydrophilic and violet #l' polymer having a hydrophobic compound as a ``Geshinaril:F1'' group in the polymerizable 41 fugitive unit. The second object is to provide a silver helochloride photosensitive material containing such a hydrophilic polymer in a constituent layer and having excellent photographic performance. The inventors of the present invention have conducted various studies on the above-mentioned problem, and have developed a photosensitive polymer that has at least one monomer unit represented by the following general formulas [moon and (IJ) as constituent components]. It has been found that the above object can be achieved by using a silver rokenide photosensitive material, which is contained in at least one of the constituent layers of the material.General formula: ＄→A→− [wherein A is S $− and 00. At least one hydrophilic substituent selected from M (where M represents a hydrogen atom or an alkali metal atom, for example, a group having a monovalent cation such as hydrogen, potassium, etc.)

is (9) to (a)% by weight. ] General formula [11] [In the formula, B represents a vinyl monomer having a group capable of crosslinking with gelatin directly or via a gelatin hardening agent,
The above-mentioned groups are also intended to include precursors that form groups that can be crosslinked by the action of alkali. y is 1 to IO%. That is, the polymer contained in the constituent layers of the silver rokenide photosensitive material of the present invention has at least two polymerizable vinyl monomers as monomer units, and one of the vinyl monomers has a hydrophilic group. The other vinyl monomer has a hydrophobic compound as a photographically useful group, and the other vinyl monomer has a group (which may also be a precursor group) that forms a crosslink with gelatin, and it occupies the polymer of the former vinyl monomer. Since the weight ratio was lower than that of the latter vinyl polymer, the polymer as a whole exhibits hydrophilic properties. Therefore, when the above-mentioned polymer according to the present invention is incorporated into the base material constituting layer, when it is mixed with gelatin as a dispersion medium, the mixing ratio should be adjusted as appropriate depending on the photographic decoration since it has high compatibility with 171j gelatin. It has the advantage of being widely available. Furthermore, since the vinyl monomer, which is the monomer unit of the upper self-polymer, contains a group that can form crosslinks with gelatin, the polymer mixed in gelatin will bond with gelatin by forming crosslinks. Because it is a polyester, there is no need for an additional emulsification step, and it also has excellent compatibility with gelatin. From these points of view, the use of the above polymer according to the present invention effectively prevents the diffusion of compounds having photographically useful groups within or between layers, and at the same time does not deteriorate the physical properties of the gelatin film, making it suitable for photographic applications. , is significantly effective. In addition to the above-mentioned monomer units, the polymer according to the present invention may also contain additional monomer units having a compound having a photographically useful group with various functions, if necessary. The silver rokenide photosensitive material of the present invention will be explained in detail below.

Next, the monomer unit B represented by the general formula fil+ in the present invention is a group (or, in front of it, a building block) capable of crosslinking with gelatin directly or via a gelatin hardener (r: a vinyl monomer with Therefore, the vinyl monomer may have a carrier group capable of forming a direct bridge with gelatin (where ρ has an active group capable of displacing a gelatin hardener, for example). It may have a unique linking group and a gelatin hardening agent as a substituent at the tip of this linking group, so that it can form a crosslink with gelatin with the hardening agent. Examples of gelatin hardeners suitable for incorporation into the polymer according to the present invention include aldehyde hardeners such as formalin, glyoxal, etc.
