    • A color imaging device which comprises an adhesive layer between (a) means for sensing radiation comprising a planar array of charge-handling semiconductive photosensors, and (b) superimposed filter means for controlling access of radiation to the sensing means comprising a transparent polymer layer capable of receiving dyes such as heat transferable dyes; the adhesive layer comprising a polyester selected from the group consisting of (1) polyesters having recurring carboxylate units of which at least 80 mole percent are terephthalate units, and recurring alkylene units derived from glycols of which at least 40 mole percent are ether alkylene units, with the proviso that either (a) the recurring alkylene units comprise at least 60 mole percent ether alkylene units or (b) either the recurring carboxylate units comprise at least 2 mole percent pyromellitic tetracarboxylate units or at least 10 mole percent of linear aliphatic dicarboxylate units having at least 8 carbon atoms, and that when at least 10 mole percent of the carboxylate units are said linear aliphatic dicarboxylate units, the total of the mole percent of lower aliphatic dicarboxylate units of the recurring carboxylate units plus the mole percent of ether alkylene units of the recurring alkylene units is at least 60 mole percent and (2) polyesters having recurring alkylene units and recurring carboxylate units wherein at least 30 mole percent of the carboxylate units are alicyclic dicarboxylate units and wherein the remaining carboxylate units are nonlinear aromatic dicarboxylate units. A method for preparing such devices, color filter arrays useful therein and imaging elements useful therein are also described.
    • 一种彩色成像装置,其包括在(a)用于感测辐射的装置之间的粘合剂层,所述装置包括电荷处理半导体光敏传感器的平面阵列,以及(b)叠加的滤波器装置,用于控制辐射对感测装置的访问,包括透明聚合物层, 接收染料如可转印染料; 所述粘合剂层包含选自(1)具有至少80摩尔%为对苯二甲酸酯单元的重复羧酸酯单元的聚酯和衍生自其至少40摩尔%为醚亚烷基单元的二元醇的重复亚烷基单元的聚酯, 条件是(a)重复的亚烷基单元包含至少60摩尔%的醚亚烷基单元,或(b)重复羧酸酯单元包含至少2摩尔%的均苯四酸四羧酸酯单元或至少10摩尔%的直链脂族二羧酸酯单元 具有至少8个碳原子,并且当至少10摩尔%的羧酸酯单元是所述直链脂肪族二羧酸酯单元时,重复羧酸酯单元的低级脂肪族二羧酸酯单元的摩尔百分比加上醚亚烷基单元的摩尔百分数 的重复亚烷基单元为至少60摩尔%,和(2)具有重复亚烷基的聚酯 ts和重复羧酸酯单元,其中至少30摩尔%的羧酸酯单元是脂环族二羧酸酯单元,其中剩余的羧酸酯单元是非线性芳族二羧酸酯单元。 还描述了制备这种器件的方法,其中使用的滤色器阵列和其中有用的成像元件。
