Abstract
PURPOSE: To obtain inexpensive polychromic filters by a simple method by eluting and removing silver after setting a white/black silver halognide emulsion on the supporting body, exposing the 1st color pattern and carrying out outer color development to form a pattern which includes the 1st color and silver and repeating the similar method for other colors and black to form respective patterns.
CONSTITUTION: For example, when a 3-color filter is produced, white/black silver halogenide emulsion layer 21 is formed on supporting body 20 consisting of glass, quartz, synthetic resin and so on. A picture of pattern 22 of the 1st color, for example cyanic color, is exposed through a photomask and then developed with outer color developer which includes cyan-coupler, causing a pattern consisting of cyanic dyestuff and silver particles to be formed. Then silver particles are bleached. The patterns of the 2nd and 3rd colors, for example yellow and green, can be obtained by repeating the same process. At last, black patter 24 is formed on unexposed part 23 in the same manner. Thus, economical polychromic filters can be obtained by the simple method.
