Description

Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION The present invention has the following properties: slipperiness, vacuum adhesion,
The present invention relates to a silver halide photographic light-sensitive material having improved matte pins and the like.

[0002]

BACKGROUND OF THE INVENTION Generally, a hydrophilic colloid represented by gelatin is used as a binder in the outermost layer of a silver halide photographic light-sensitive material. For this reason, the surface of the silver halide photographic light-sensitive material has increased adhesiveness or tackiness in an atmosphere of high temperature and high humidity, and when it comes into contact with another object, it easily adheres to it. This adhesion phenomenon occurs between the light-sensitive materials or between the light-sensitive materials and other objects in contact with the light-sensitive materials during manufacturing, storage, shooting, processing, projection, or storage after processing. It was a serious breakdown.

In order to solve this problem, inorganic substances such as silicon dioxide, magnesium oxide, titanium dioxide and calcium carbonate, polymethylmethacrylate, cellulose acetate propionate and methylmethacrylate are used for the outermost layer.
By incorporating fine particles of an organic substance such as a methacrylic acid copolymer to increase the roughness of the surface of the photosensitive material and to make it a so-called matte, the adhesiveness is reduced, and the antistatic effect and especially in the step of returning in printing are performed. It has been proposed to improve the vacuum adhesion to the printer and reduce the vacuum time.

For this purpose, generally, the amount of the matting agent is increased and the grain size is increased, but the sinking of the matting agent into the silver halide emulsion layer becomes a mat pin. Will cause serious drawbacks.

Therefore, in order to avoid this, it is known that the thickness of the matting agent-containing layer is increased or the matting agent is prevented from sinking by slowly drying it. For example, in JP-A 3-127049, the coating surface temperature at a weight ratio of water to binder of 800 to 200% is 19 ° C. or less,
Also, a technology for drying over 35 seconds has been disclosed, and although the effect is certainly recognized, it is a constraint condition for increasing productivity, and development of a technology that does not increase matte properties and matte pins even when performing rapid drying. Is desired.
