PURPOSE: To obtain picture images showing high contrast by preparing a photosensitive material using photosensitive microcapsules of this invention.

CONSTITUTION: The microcapsule contains a photosensitive silver halide, reducing agent, polymerizable compd., and base and/or base precursor. The production method of this microcapsule features in that the outer shell of the microcapsule is formed by the reaction of hydrophobic melamine deriv. and/or urea deriv. dissolved in a polymerizable compd. with formaldehyde in an aq. soln.
