難である。 Conventionally, such colored images have been formed by providing a dye-receiving layer capable of adsorbing or impregnating anionic dyes on a transparent support, and then coloring the layer with the same type of dye. In this case, casein, gris, gelatin, and polyvinyl alcohol (PVA) membranes are used as the dye-receiving layer because they are superior to other polymer membranes in terms of dye adsorption rate, and it is easy to obtain highly concentrated colored images with thin membranes. It is used. However, the adsorption amount of anionic dyes alone is limited by the thickness of the dye-receiving layer, and generally, when the film thickness of casein, gris, gelatin, or PVA film is approximately 1μ, a concentration of about 2 is required. It was at its limit. In addition, when adsorbing multiple types of anionic dyes in a mixed system, dyeing and density may decrease due to blocking development between the dyes, and dyes with significantly different affinities to the substrate may have different affinities depending on dyeing time. The weak dyes may be driven out over time, causing the hue to change, making it difficult to control the spectral properties with high precision.

機染料で可能となるものである。 In order to overcome the drawbacks of the prior art as described above, the present invention provides casein formed on a transparent support,
After the anionic dye is adsorbed or impregnated into the dye-receiving layer, which is made of a polymer membrane such as gris, gelatin, or PVA and can adsorb or impregnate anionic dye, cationic dye is absorbed into the adsorbed or impregnated anionic dye. It is characterized by adsorbing dyes, and by doing this, the dyeing density of cationic dyes is added to the dyeing density of conventional anionic dyes, resulting in high concentrations (e.g.
3.5) is obtained. This makes it possible to use organic dyes to produce optical blacks for color separation filters for image pickup tubes and solid-state image pickup devices, which were conventionally not possible with organic dyes.

たい場合においてもこの方法が適用できる。 The dyeing mechanism of the cationic dye of the present invention is that there is almost no adsorption of the cationic dye to the polymer membrane itself such as casein, gris, gelatin, PVA, etc., and the -SO - Since it is thought that it adsorbs to anionic groups such as -3 group and -COO - group, the amount of adsorbed cationic dye does not depend on the film thickness of the chromosome and is already adsorbed.
or determined by the amount of anionic dye being impregnated. That is, since the cationic dye is also dyed synergistically to the membrane that is sufficiently impregnated with the anionic dye at the beginning, a high dyeing concentration can be easily obtained. Also,
Since the desired spectral transmittance characteristics, such as the green spectral transmittance characteristics, cannot be obtained with a single dye, even when forming by combining cyan and yellow dyes, an anionic cyan dye is first used to improve the cyan side spectral characteristics. By forming the desired green spectral characteristics and then forming the yellow side spectral characteristics with a cationic yellow dye, it is possible to easily obtain the desired green spectral characteristics.
and can be obtained with high precision. In addition to green, this method can also be applied when it is desired to modify the spectral characteristics of a single dye using another dye.

色可能となる。 Furthermore, the present invention can be applied to alkylbenzene sulfonic acid instead of the anionic dye used initially when dyeing casein, gris, gelatin, PVA, etc., with only a cationic dye that has almost no staining property. Dyeing is possible by using an organic acid that is colorless and transparent and has an affinity for chromosomes, such as an alkylbenzene sulfonate, such as dodecylbenzene sulfonic acid.
