OPTICAL RECORDING SHEET DEPOSITED WITH MICROCAPSULE-CONTAINING AGENT INTERNALLY CONTAINING COLOR-CHANGING HYBRID VESICLE-CONTAINING MATERIAL AND OPTICAL RECORDING METHOD USING THIS SHEET

摘要

PURPOSE:To inexpensively obtain high-quality full-color recorded images having a high resolution and fine density gradation characteristic by a simple device. CONSTITUTION:The monocolor optical recording paper P is formed by depositing the microcapsule-contg. material CC formed by dispersing and mixing microcapsules MC into and with a binder resin 2 on base material paper 1. The color-changing hybride vesicle-contg. material forming a hybride vesicle HV formed by dissolving the hybride vesicle contg. a color developer 3 and a dye precursor 4 into a solvent 5 is internally included in the microcapsules MC. The microcapsule filth Vf forming the hybride vesicle HV has the film structure in which the domain DL of a low-molecule bimolecular film and the domain DH of a high-molecule bimolecular film are separated in phase. A photoisomerizing material which is isomerized by receiving photoirradiation of specific wavelengths is introduced into this low-molecule bimolecular film.
