Summary: | To provide a favorable variable transmission electrophoretic devices.SOLUTION: A variable transmission film may include an electrophoretic medium having a plurality of capsules and a binder, each capsule containing a plurality of electrically charged particles and a fluid, the charged particles being movable by application of an electric field and being capable of being switched between an open state and a closed state. The film may include at least one of: a binder containing fish gelatin and a polyanion; a binder containing one or more tinting agents; capsules containing charge control agents, such as an oligoamine-terminated polyolefin and a branched-chain fatty acid comprising at least 8 carbon atoms; a selection of capsules in which at least 60% have diameters between 50 μm and 90 μm and at least 15% have diameters between 20 μm and 49 μm; a tinted adhesive layer; and a fluid selected from one or more nonconjugated olefinic hydrocarbons.SELECTED DRAWING: Figure 1F
【課題】好適な可変透過率電気泳動デバイスを提供すること。【解決手段】可変透過率フィルムは、複数のカプセルと、結合剤とを有する、電気泳動媒体であって、各カプセルは、複数の荷電粒子と、流体とを含有し、荷電粒子は、電場の印加によって移動可能であり、開状態と閉状態との間で切り替えられることが可能である、電気泳動媒体を含み得る。フィルムは、魚ゼラチンと、ポリアニオンとを含有する結合剤、1つ以上の着色剤を含有する結合剤、オリゴアミン末端ポリオレフィンおよび少なくとも8つの炭素原子を含む分岐鎖脂肪酸等の電荷制御剤を含有するカプセル、少なくとも60%が50μm〜90μmの直径を有し、少なくとも15%が20μm〜49μmの直径を有する一連のカプセル、着色接着剤層、および1つ以上の非共役オレフィン系炭化水素から選択される流体のうちの少なくとも1つを含み得る。【選択図】図1F |
