Disclosed is a coating comprising a polymeric layer, wherein the polymeric layer comprises a reaction product of a first monomer comprising two or more aromatic acetylene groups and a second monomer comprising two or more cyclopentadienone groups, or a cured product of the reaction product. The coating may or may not additionally contain a crosslinker and/or a thermal acid generator. Optical thin films made from the coatings exhibit refractive indices that make them useful as interlayers for matching refractive indices between adjacent layers of display devices; thereby improving device output efficiency.
公开了一种包含聚合物层的涂层,其中聚合物层包含由两个或两个以上芳香族
乙炔基团组成的第一单体和由两个或两个以上
环戊二烯酮基团组成的第二单体的反应产物,或该反应产物的固化产物。涂层可以额外含有或不含有
交联剂和/或热酸发生剂。由这些涂层制成的光学薄膜具有折射率,可用作夹层,使显示设备相邻层之间的折射率相匹配,从而提高设备的输出效率。
