PURPOSE:To provide color-changing microgel contents capable of accurately obtaining a desired color easily and the control method of the color-changing light by densely controlling a substance diffusion related to a microgel by light irradiation. CONSTITUTION:A microgel MG has photosensitive groups, which are ion- dissociated by receiving the irradiation of light having a specific wavelength nu, and dye precursors 3 are taken into internal network structure. Developers 5 generating a color development reaction with the dye precursors 3 are arranged in gel outer phase. The micro-capsule content is irradiated with light R containing component light having the specific wavelength nu, the photosensitive groups of the microgel M are ion-dissociated and the network structure is spread, and the dye precursors 3 and the developer 5 are diffused mutually and the color development reaction is generated. |
