Subsequently, a liquid radiation-sensitive composition containing green and blue pigments dispersed therein is applied, pre-baked, exposed to radiation, and developed similarly to sequentially form an arrangement of green pixels and an arrangement of blue pixels on the same substrate. In order to obtain the color filters with three arrangements of the main color pixels of red, green and blue on the substrate, the arrangement order of the pixels used to produce the color filters is not limited to the above order. The substrate used to produce color filters is made of glass, silicon, polycarbonate, polyester, aromatic polyamide, polyamideimide, or polyimide. The substrate can be appropriately Treatments such as chemical treatment with a silane coupling agent, plasma treatment, ion implantation, sputtering, vapor phase reaction or vacuum deposition. When applying the liquid composition, suitable coating techniques such as spin coating, cast coating or spin coating can be used. The thickness of the coating film after drying is preferably from 0.1 to 10 microns, more preferably from 0.2 to 5.0 microns, and particularly preferably from 0.2 to 3.0 microns. The radiation used to produce the color filter is selected from the group consisting of visible radiation, ultraviolet radiation, far ultraviolet radiation, electronic radiation, and X-ray radiation. The preferred wavelength is 190 to 450 nm. The radiation energy is preferably 10 to 10,000 joules / square meter. The above alkaline developer is preferably sodium carbonate, sodium hydroxide, potassium hydroxide, tetramethylammonium hydroxide, choline, 1,8-diazabicyclo-one [5.4.0] -43 · (40) (40) 200426404 —7-undecene or 1,5-diazabicyclo- [4 · 3 · 0] -5—nonene in water.

After the development with the alkaline developer, it is preferable to wash the coating film. The development may be shower development, spray development, immersion (immersion) development, kneading development, and the like. As for the development situation, it is preferable to perform the development at normal temperature for 5 to 300 seconds. When the shower development is performed at a temperature of 23 ° C and a development pressure of 1 kgf / cm2 (nozzle · diameter 1 mm), the dissolution time of the unexposed portion is longer than that of a radiation-sensitive composition conventionally used for color filters. 20 seconds long, the following examples clearly indicate that the radiation-sensitive composition for color filters of the present invention is 20 seconds or less. The color filters thus produced are very suitable for use in, for example, color liquid crystal displays, color image capturing tube devices, and color sensors. The radiation-sensitive composition used in the color filter of the present invention does not produce residues or stains on the substrate and the light scanning layer that are not exposed during the development process, because its alkali solubility is greatly improved, which can reduce its alert time and Can form high sharpness and high quality pixels. Therefore, the radiation-sensitive composition for color filters of the present invention is very suitable for producing color filters, including color filters for color liquid crystal display devices and color filters for color decomposition of solid-state image devices.
