PROBLEM TO BE SOLVED: To provide a photosensitive micrcapsule which can form a sharp image having enough high density, good tone and no blur by controlling the photosensitive wavelength of a photosensitive material included in a cyan-color developing photosensitive microcapsule (C capsule). SOLUTION: The microcapsule consists of a C capsule 1 having a hollow part inside and a photosensitive material 3 which has the max. sensitivity for hardening near 650nm wavelength and fills the inside hollow part of the capsule 1. The capsule wall material 2 contains an optical filter material having a spectral filtering function, namely, a material which absorbs or reflects light in <=600nm wavelength region. |
