Abstract:
The present invention provides a color tone variable film which is formed by a reaction of a cationic polymer containing a structural unit containing a positive ionic group in a side chain and a compound containing an acid group and a partial structure which can change color tone as a result of energy application, which can be formed by a wet method, which has flexibility and strength in practical use, and which changes color tone with high sensitivity as a result of energy application, a simple manufacturing method thereof, and an electrochromic element obtained by the manufacturing method.
