Magenta filters are disclosed which comprise an indolocarbocyanine dye in which the 3-carbon atom of each indole nucleus has bonded thereto at least one alkyl group which has from 3 to 12 carbon atoms and which is unbranched at the first carbon atom thereof. The filters are useful in filter arrays comprising sets of differently colored filters wherein one set of filters comprises such an indolocarbocyanine dye, and light sensing semiconductor devices comprising such color filter arrays.
本发明公开了包含
吲哚羰
花青染料的品红色滤光片,其中每个
吲哚核的 3 个碳原子上至少键合有一个烷基,该烷基具有 3 至 12 个碳原子,且在其第一个碳原子上未支链。这种滤光片可用于由不同颜色的滤光片组成的滤光片阵列,其中一组滤光片包括这种
吲哚羰
花青染料,以及包括这种彩色滤光片阵列的光感应半导体器件。
