Abstract
An improved color filter array comprises a transparent heat-transfer dye-receiving layer containing an array of filter elements wherein the dye-receiving layer is a certain polyester wherein at least 30 mole percent of the recurring units contain a saturated gem-bivalent radical having a saturated polycyclic three-dimensional structure that includes a saturated bicyclic atomic bridge hydrocarbon ring member. The improved dye-receiving layers provide filter elements with excellent edge sharpness. The improved color filter arrays are useful in color imaging devices, such as solid-state video cameras.
