Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a silver halide photographic light-sensitive material, and more particularly to a light-sensitive material with improved transportation troubles.

[Background of the invention]

Transport troubles in newspaper facsimile plotters have long been seen as a problem, and improvements have been requested.

In terms of improvements to the equipment, the suction cup that sucks up the film has been made into a swinging type, which shakes off clinging film, and a dehumidifier has been installed to eliminate the film from sticking to each other. In order to improve the film, attempts have been made to add several types of cloaking agents to the emulsion side and to add large amounts of particles with small particle sizes, but none of these methods have been able to significantly improve transport problems. Ta.

[Purpose of the invention]

In view of the above-mentioned problems, an object of the present invention is to provide a silver halide photographic material that has significantly improved adhesion and transportation troubles.

[Structure of the invention]

The above object of the present invention is to provide a silver halide photographic material having at least one light-sensitive silver halide emulsion layer on a support, in which at least one layer in the silver halide photographic material has an average grain size of 10 μm. This was achieved using a silver halide photographic material characterized by containing a larger matting agent.

The details of the present invention will be explained below.

The capping agent used in the present invention is a powder of an organic or inorganic compound. Specific organic compounds used include water-dispersible vinyl polymers such as polymethyl methacrylate, cellulose acetate propionate, and starch. In particular, spherical mats of water-dispersible vinyl polymers, such as homopolymers of acrylic esters such as methyl methacrylate, grindyl acrylate, and grindyl methacrylate, or copolymers of these acrylic esters with other vinyl monomers. Agents are preferred. Inorganic compounds include silver halide, barium strontium sulfate, carbonate, silicon dioxide, magnesium oxide,
Boron nitride, hollow silica (manufactured by Nippon Fillite Co., Ltd.), tetrafluoroethylene, titanium oxide, and the like are preferably used.

The amount added is 1 mg/m"-100 mg/m", preferably 50II1 g/1112 to 500 mg/mff. Average particle size is greater than 10μm, preferably 30μm
m or less. If it is larger than 100 μm, the matting agent is likely to peel off from the film surface, causing plotter failure, etc., which is not preferable. The layer to be added may be a subbing layer for improving adhesion to the gelatin layer, a silver emulsion layer, an emulsion protective layer, an antihalation layer, a backing layer, or a backing protective layer, but it is preferable. is the backing side layer, more preferably the banking protection layer. The particle size can be measured by electron microscopy or Coulter counter.

The silver halide emulsion used in the light-sensitive material of the present invention may be obtained by any of the acid method, neutral method, and ammonia method, and preferably has a grain size of 0.2 μm or more and 0.5 μm or less.

A water-soluble rhodium salt and a water-soluble iridium salt are added to the silver halide grains used in the emulsion of the present invention during the grain formation process, and are included inside the grains and/or on the grain surfaces. The amount added is 10 per mole of silver halogenide.
-6 to 10-9 mol is preferred.

The silver halide grains may have a uniform silver halide composition distribution within the grain, or may be core/nyl grains in which the silver halide composition differs between the inside and surface layer of the grain. The latent image may be formed primarily on the surface of the particle, or may be formed primarily within the particle.

The silver halide grains according to the present invention may have any shape. be able to. One preferred example is floo1
It is a cube with planes as crystal surfaces.

Particles having twin planes may also be used.

The silver halide grains according to the present invention may be of a single shape or may be a mixture of grains of various shapes.

A polydisperse emulsion and a monodisperse emulsion may be mixed and used.

The silver halide emulsion may be a mixture of two or more separately formed silver halide emulsions.

As monodisperse silver halide grains in a monodisperse emulsion, the weight of silver halide contained within a grain size range of ±20% around the average grain size r is 60% or more of the weight of all silver halide grains. A certain amount is preferable, particularly preferably 70% or more, and still more preferably 80% or more.

Here, the average particle size T is the product of the frequency of particles with particle size r1 and ``13 x ri', or the particle size when the maximum is ``1''.

(3 significant digits, round off the smallest digit.) The grain size here refers to the diameter in the case of spherical silver halide grains, and the projected image in the case of grains with shapes other than spherical. This is the diameter when the circumferential area is converted into a circular image.

The particle size can be obtained, for example, by photographing the particles with an electron microscope at a magnification of 10,000 to 50,000 times, and suddenly measuring the particle diameter or projected area on the print. (1
