WIPO Patent Application WO/2019/112121
Kind Code:
A1
Abstract:
Disclosed are a method for producing a photoresponsive automatic color change precursor and a photoresponsive automatic color change element, and a photoresponsive automatic color change element produced thereby. A method for producing a photoresponsive automatic color change precursor and a photoresponsive automatic color change element, and a photoresponsive automatic color change element produced thereby according to the present invention are characterized in that the method includes a step for adding or adsorbing a ligand material to a reducing color change material, a semiconductor material, or an electron transfer material to produce a reducing color change mixture that changes color through a photoresponse. Accordingly, effects are exhibited wherein handleability and storability are facilitated by means of a simple structure, discoloration and color change can be performed by driving the photoresponsive automatic color change element by using electrical power self-generated using external light, and the rate of discoloration in particular is remarkably improved.
