摘要：
Electrochromic compositions suitable for use in electrochromic media in electrochromic devices contain minimally two electrochromic compounds of the same redox type, whose redox potentials are greater than 30 mV. The lower redox potential electrochromic compound makes a large contribution to the absorbancy of the electrochromic medium despite being present in only minor concentration.
