MANUFACTURING METHOD OF DIMMER FILM AND DIMMER LAYERED PRODUCT

摘要

<P>PROBLEM TO BE SOLVED: To provide a manufacturing method of a dimmer film which can be cut in an optional shape and whose light transmittance is changed by application of low voltage. Ž<P>SOLUTION: The manufacturing method of the dimmer film includes a step 1 for mixing a liquid crystal-poly(vinyl acetal) solution in which a liquid crystal and poly(vinyl acetal) are dissolved in an organic solvent with a poor solvent of the liquid crystal to obtain a liquid crystal microcapsule dispersion liquid, a step 2 for mixing a binder resin solution in which a binder resin is dissolved in an organic solvent with the liquid crystal microcapsule to prepare a mixed solution and a step 3 for preparing the dimmer film containing the liquid crystal microcapsule using the mixed solution.
