Abstract
The invention relates to a photosensitive microcapsule in which the image forming material comprises at least one of a dyeprecursor, a dye, and a pigment and the photosensitive material changes its mechanical strength by reacting to light. Moreover, the image forming material and the photosensitive material are separated from one another within the microcapsule. Therefore, the photosensitive microcapsule has high photosensitive sensitivity, yet can form an image with high resolution, high color reproduction and high density.
