Patent number: 9040647Abstract: Provided are: a method for controlling the decoloration reaction rate and color density of a fast light-modulating material to levels suitable for practical use; and a fast light-modulating material having a decoloration reaction rate and a color density which are suitable for practical use. A polymer obtained by polymerizing a paracyclophane-bridged hexaarylbisimidazole compound having a radical-polymerizable group, and a copolymer obtained by copolymerizing the compound with a (meth)acrylic acid compound or a sensitizer having a radical-polymerizable group can achieve controlled decoloration reaction rates, photosensitivity and color tones.Type: GrantFiled: November 30, 2010Date of Patent: May 26, 2015Assignees: MITSUBISHI GAS CHEMICAL COMPANY, INC.Inventors: Jiro Abe, Atsuhiro Tokita, Takeru Horino, Toyoji Oshima, Atsushi Kimoto
