る。 Color solid-state imaging devices, such as color image pickup tubes, color charge coupled devices (CCDs), and charge injection devices (CIDs), generally have stripes or mosaics of several different colors. Color separation filters are used. Color separation filters include dichroic filters made of multilayer interference thin films and organic dyed filters dyed with water-soluble resin.Currently, organic dyed filters are widely used in terms of cost, accuracy, and quality. Conventional organic dyeing filters are made by coating a photosensitive water-soluble resin layer on a transparent support, attaching a mask to it, exposing it to light, developing it to form a relief image in a predetermined shape, and then dyeing it with water-soluble dyes such as acid dyes. After dyeing to form the first color, a dye-resistant intermediate layer is provided and the above steps are repeated to form the second color. Such a manufacturing process is not only complicated, but also requires highly accurate positioning of the first color relief colored image and the second color relief colored image, which reduces the manufacturing yield of color separation filters. This is a contributing factor.

水溶液中で染色する。 Next, a photosensitive water-soluble resin layer 3 is coated on the oil-soluble resin layer 2 (FIG. 2). The water-soluble resin layer includes casein, gelatin, gris,
Suitable materials include polyvinyl alcohol, polyvinylpyrrolidone, etc. to which diglomate or chromate is added to impart photosensitivity. After forming the water-soluble resin layer, a mask of a predetermined shape is closely attached, exposed, and then developed with warm water to form a patterned relief image of the water-soluble resin layer 3' (FIG. 3). Next, using the water-soluble resin layer 3' patterned with a dye that can be sublimated or thermally melted and vaporized as a mask, the oil-soluble resin layer 2 is transferred and dyed through the gap to form a colored image 4 of the first color. Figure 4). Disperse dyes, cationic dyes, oil-soluble dyes, etc. are used as dyes that can be sublimed or thermally melted and vaporized. Disperse dyes include Sumikaron Red 3G (manufactured by Sumitomo Chemical Co., Ltd.), Miketone Polyester Red FB (manufactured by Mitsui Chemicals Co., Ltd.), Sumikalon Blue BR (manufactured by Sumitomo Chemical Co., Ltd.), etc., and cationic dyes include Eisen Carotene Red 6BH (manufactured by Hodogaya Chemical Co., Ltd.). Astrazone Blue G (manufactured by Kagaku Co., Ltd.) (manufactured by Bayer), etc. is used. Methods for transferring the dye include a method in which a transfer paper coated with the above-mentioned dye with a binder is bonded to a base material under heat and pressure, and a method in which the dye is transferred by vaporizing it under reduced pressure such as a vacuum evaporation method. be able to. Thereafter, the colored image 5 of the second color is formed by immersing it in an aqueous solution in which an acidic dye or the like is dissolved.
