<p><P>PROBLEM TO BE SOLVED: To provide a method for controlling a high-speed dimming material so as to have a practical dimming reaction rate or degree of color deepness, and to provide the high-speed dimming material having a practical dimming reaction rate or degree of color deepness. <P>SOLUTION: The dimming reaction rate, photo sensitivity and color tone can be controlled by a polymer produced by polymerizing hexaarylbisimidazole compound crosslinked with paracyclophane having a radical polymerizable group, or a copolymer produced by copolymerizing the hexaarylbisimidazole compound and a compound of (meth)acrylic acid family or a sensitizer having a radical polymerizable group. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
