| 摘要 |
An electrochromic device comprising a pair of electrically conductive substrates disposed facing each other and each having at least on its inner surface an electrode at least one of said electrically conductive substrates comprising a transparent substrate and a transparent electrode, an ion conductive material inserted between said pair of electrically conductive substrates, an electrochromic material-containing layer disposed between either one of said electrodes and said ion conductive material and an ultraviolet absorptive layer disposed between either at least one of said transparent substrates and the electrode disposed thereover or on the surface of said transparent substrate opposite to the transparent electrode disposed thereover, said ultraviolet absorptive layer being formed by coating and curing on the surface at said transparent substrate a reaction product of (A) an aminosilane compound of the formula (I) or the derivative thereof and (B) an ultraviolet absorptive material having in its molecules a carboxyl group, said formula (I) being represented by wherein R1 is a C1-C10 alkylene group or a divalent group of the formula -(CH2)m-NH-m in which m is an integer of 1-4, the groups R2 are the same or different and each selected from the group consisting of a hydrogen atom, a hydroxyl group, a halogen atom, a C1-C10 alkyl group and a C1-C10 alkyl group provided that at least one of the groups R2 is an alkoxy group or a hydroxyl group and n is an integer of 0 or greater; said reaction product having amide bonds derived from said aminosilane compound or the derivative thereof.
