ABSTRACT:
The present invention relates to a method for preparing a coloring layer composition for a chromatic device comprising a step of preparing a peroxotungstic acid solution comprising a solute including WO.sub.3 .circle-solid.aNb.sub.2 O.sub.5 .circle-solid.bH.sub.2 O.sub.2 .circle-solid.cH.sub.2 O (a, b, and c represent a positive number), water for dispersing and holding the solute, and an organic solvent compatible with water, and aging the peroxotungstic acid solution to obtain a polymer. According to the method of the present invention, a large size chromatic device can be reliably produced at a low cost. Further, a composition having a sufficient coloring effect and a quick response speed of the coloration-bleaching change in the chromatic device can be prepared.
