PURPOSE:To manufacture the microcapsules having photoresponsive films at low cost from wide ranges of materials and to provide the method for easily and precisely controlling color development reaction based on interdispersion of color change materials from the inside and outside to the other sides through these films. CONSTITUTION:Bimolecular built-up films 3 containing an organic dye responding to light of wavelength nu2 to change electron transfer performance and a conformation isomerizing substance responsing to light of wavelength nu2 and being excited are buried in the thin pores 2 of the film Cf of each microcapsules MC, and a dye precursor 6 and a color developer 8 are placed in the inside and outside of the microcapsules MC, thus permitting the bimolecular built-up films 3 to be elevated in material permeability by irradiating with the lights R1 and R2 (wavelengths of nu1 and nu2), the dye precursor 6 and the color developer 8 can both sides to be interdispersed to the other sides through the films 3 and the color to be developed. |
