KR970042937A - Electrochromic Composition - Google Patents

Abstract

The electrochromic composition of the present invention prepared using (C ₆ H ₅ ) ₃ BCN- as the anion of the negative electrode reduction component does not produce insecticidal phenomenon even after long-term use, and the color appears uniformly. This has a short effect.
