Light-sensitive material containing silver halide, reducing agent and polymerizable compound with silver halide outside and inside of microcapsules

DETAILED DESCRIPTION OF THE INVENTION Examples of the silver halide employable in the light-sensitive sensitive material of the present invention include silver chloride, silver bromide, silver iodide, silver chlorobromide, silver chloroiodide, silver iodobromide and silver chloroiodobromide in the form of grains.
The halogen composition of individual grains may be homogeneous or heterogeneous.
The heterogeneous grains having a multilayer structure in which the halogen composition varies from the outer surface portion (i.
e.
, shell) to the inside portion (i.
e.
, core) are described Japanese Patent Provisional Publication Nos.

A silver halide grain having a core/shell structure in which the silver iodide content in the shell is higher than that in the core can be also employed as described in Japanese Patent Provisional Publication No.
62(1987)-183453.
There is no specific limitation on the crystal habit of silver halide grains.
For example, a tabular grain having an aspect ratio of not less than 3 can be used as described in Japanese Patent Provisional Publication No.
62(1987)-210455.
Two or more kinds of silver halide grains which differ in halogen composition, crystal habit, grain size, and/or other features from each other can be employed in combination.
There is no specific limitation on the grain size distribution of silver halide grains.
For example, silver halide grains having an almost uniform grain size distribution can be employed, as described in Japanese Patent Provisional Publication No.

The silver halide grains preferably have a mean grain (or particle) size of 0.

In the light-sensitive material of the present invention, silver halide is not only contained in the microcapsules, but also arranged outside of the microcapsules.
The silver halide arranged outside of the microcapsules may be the same as the silver halide contained in the microcapsules
