To provide polymer formulations for use with electrooptic media.SOLUTION: The polymer formulations include urethane acrylates, adhesion promoters, and conductive monomers. By selecting suitable conductive monomers, it is possible to achieve formulations having a volume resistivity of 10to 10Ohm cm after conditioned for one week at 25°C and 50% relative humidity. Such formulations are suitable to be incorporated into electrooptic materials, such as electrooptic displays or variable transmission films, e.g., for architectural applications. In other embodiments, the formulations additionally include metal oxide nanoparticles to alter the refractive index and/or conductivity. Adding certain metal nanoparticles also promotes non-destructive measurement of the layer thickness using X-ray fluorescent spectroscopy.SELECTED DRAWING: None 【課題】電気光学媒体との使用のためのポリマー配合組成を提供すること。【解決手段】ウレタンアクリレート、接着促進剤、および伝導性モノマーを含む、ポリマー配合組成。好適な伝導性モノマーを選択することによって、１週間、２５℃および５０％相対湿度において調整された後、１０６〜１０１０Ｏｈｍ・ｃｍの体積抵抗率を有する配合組成を達成することが可能である。そのような配合組成は、例えば、建築用途のための電気光学ディスプレイまたは可変透過性フィルム等の電気光学材料の中に組み込むために好適である。他の実施形態では、配合組成は、加えて、酸化金属ナノ粒子を含み、屈折率および／または伝導性を改変する。ある金属ナノ粒子の添加は、加えて、Ｘ線蛍光分光法を使用して、層厚の非破壊測定を促進する。【選択図】なし
