Photosensitive sheet and a method for the formation of images using the same

A photosensitive sheet for recording a color image, consisting essentially of:

• a sheet-shaped substrate having first and second opposed surfaces, including on said second opposed surface at least one light-reflective surface to reflect light,
• said light-reflective surface absorbing at least one component of the red, green, and blue components of the exposed light, said light-reflective surface reflecting light different from said exposed light in at least one of said red, green, and blue light components, to compensate the sensitivities of three kinds of photosensitive materials to substantially the same extent;
• and
• a coating on said first opposed surface of said sheet-shaped substrate of three kinds of pressure-rupturable capsules, each of said three kinds of capsules containing one kind of colorless chromogenic material and one kind of photosensitive material,
• said photosensitive materials selected from the group consisting of photosensitive materials individually sensitive to red, green, and blue light, and said photosensitive materials adapted to harden when exposed to light passing directly through said pressure-rupturable capsules or reflected light from said light-reflective substrate surface through said pressure-rupturable capsules.
