発明の構成OBJECT OF THE INVENTION [Field of Industrial Application] The present invention relates to a color filter, particularly a color filter for a liquid crystal color display panel. [Prior Art] Color filters, especially those used in liquid crystal color display panels, are produced by sequentially and repeatedly forming transparent colored image patterns of different hues on a transparent support such as a glass substrate, plastic substrate, or ceramic substrate. Manufactured. These color filters! ! ! As for the method of production,
There is a photolithography method. This method uses animal proteins such as gelatin, gruel, and casein, and P.
A photosensitive material, especially a resin, made by adding a photoreactive curing agent such as ammonium dichromate or a diazo compound to VA, etc., is applied to the substrate at the desired thickness by a spin-coding method, etc.
It dries to form a layer of photosensitive resin. However,
In this coating process, when the photosensitive resin dropped onto the substrate spreads, it flows out of the substrate and only a few to ten-odd percent remains on the substrate, so the photosensitive resin is not effectively utilized. Furthermore, since continuous production is not possible, productivity is low. [Problems to be Solved by the Invention] The purpose of the present invention is to improve the above-mentioned drawbacks of the conventional technology,
There is no process of applying photosensitive resin directly to the substrate, therefore,
It is an object of the present invention to provide a method for manufacturing a color filter that does not cause loss due to leakage of photosensitive resin to the outside of the substrate during the coating process and has high productivity. Composition of the invention

B) As shown in A, a step of providing a layer 2 of transparent colored photosensitive resin on a base film 1 and laminating a protective film 4 thereon; As shown in C, the layer 2 of transparent colored photosensitive resin is heat-pressed onto the substrate 5 together with the base film; c) As shown in D, the layer 2 of transparent colored photosensitive resin is bonded through the photomask 6; After exposure, as shown in Figure F, the base film 1 is peeled off and developed, as shown in Figure F.
a step of forming a transparent colored image pattern 8; and 2) a step of repeating steps 1 to 2 a plurality of times to form transparent colored image patterns having different hues. The second method for manufacturing a color filter of the present invention, as shown in FIG. 2 I to P, consists of the following steps. B> As shown in (2), a transparent dyeable photosensitive resin layer 3 is provided on the base film 1, and a protective film 4 is placed on top of it.
(a) As shown in J, the protective film 4 is peeled off, and as shown in K, the transparent dyeable photosensitive resin layer 3 is heat-pressed onto the substrate 5 together with the base film, c) As shown in L, after exposing the transparent dyeable photosensitive resin layer 3 to light through a photomask 6, as shown in M, the base film 1 is peeled off and developed, and as shown in N. 2) As shown in O, forming a transparent dyeable image pattern 7; 2) Dyeing the transparent dyeable image pattern to form a transparent colored image pattern 8; e) P As shown in , the step of providing a resist dyeing film 9 on the transparent colored image pattern 8, and the steps of (a) to (e) are repeated multiple times to form a transparent colored image pattern having a resisting film and having different hues. The process of doing. [Function] According to the first and second color filter manufacturing methods of the present invention, in order to provide a transparent colored photosensitive resin layer or a transparent dyeable photosensitive resin layer, coating on a base film is required. It can be carried out continuously by a flow method or the like. A continuous process can also be used to laminate the protective film thereon, and the intermediate product can be handled in the form of a roll. Next, this protective film is peeled off, and a transparent colored photosensitive resin layer or a transparent dyeable photosensitive resin layer is heat-pressed onto the substrate, thereby forming these layers on the substrate. Therefore, since there is no step of directly applying the photosensitive resin to the substrate, there is no loss of the photosensitive resin flowing out of the substrate during the coating step as in the conventional method, and the yield is improved. According to the second color filter manufacturing method of the present invention,
Although dyeing and resist dyeing steps are required, resolution is superior to the first production method, and color density can be increased. [Example 1] A transparent blue photosensitive resin having the following formulation was prepared (all "parts" are parts by weight).

A transparent green color was prepared in the same manner except that 00815 was used.
Alternatively, a blue photosensitive resin was also prepared. The transparent red photosensitive resin described above was coated onto a transparent polyethylene terephthalate film with a thickness of 100μ by a pouring method, and dried at a temperature of 70°C for 30 minutes to form a film of 5μ.
A layer of transparent red photosensitive resin was formed to a thickness of . A 100 μm thick polyethylene film was laminated on this layer and wound up. While peeling off the above polyethylene film, add a layer of transparent red photosensitive resin with dimensions of 200 x 300 m and a thickness of 1.1 m.
Using a dry film laminator (Dupont) on a glass substrate R#7059J (Corning),
Heat and pressure bonding was carried out under conditions of a heater temperature of 120° C. and a roller pressure of 0.5 Ky/linear cm. Next, after exposing the transparent red photosensitive resin layer to light through a negative film (photomask) that has a pattern arranged regularly in a mosaic pattern, the transparent polyethylene terephthalate film is peeled off, and 1.1.1- Developed by spraying with trichloroethane for 1 minute and rinsing with methylene chloride for 30 seconds to form a clear red image pattern. A transparent green photosensitive resin layer formed in the same manner as described above was heat-pressed onto the substrate having the transparent red image pattern. After exposure through a similar photomask shifted by one pitch, development and rinsing were performed to form a transparent green image pattern. Roughly, a layer of transparent blue photosensitive resin formed in a similar manner was heat-pressed and exposed through a similar photomask shifted by 2 pitches, then developed and rinsed to form a transparent blue image pattern. A color filter was obtained. A thin film of indium tin oxide is provided on each image pattern of the obtained color filter, and each image pattern is made to correspond to a counter electrode on which thin film transistors are arranged, and liquid crystal is injected between the two to form a liquid crystal type. Created a color display. When a video signal was applied to this, a good image of 1q was obtained. [Example 2] A transparent dyeable dye was prepared in the same manner as in Example 1 except that the Palcan Fast Red B pigment was not added and 1,000 parts of acrylamide, which is a dyeable polymer, was used instead. A photosensitive resin was prepared. A transparent dyeable photosensitive resin layer formed in the same manner as in Example 1 was heat-pressed onto a substrate, exposed, developed and rinsed to form a transparent dyeable image pattern. Kayanol Milling Red R3 (Japanese Herbal Medicine) 3% by weight
The above-mentioned transparent dyeable image pattern was immersed in a red acid dye bath consisting of a mixture of 4% by weight of acetic acid and 93% by weight of water at a temperature of 60°C for 3 minutes, and then washed with water.
It dried to form a transparent red image pattern. On this transparent red image pattern, the resist dye “FVRG-
10J (Fuji Pharmaceutical Co., Ltd.) was applied to a thickness of 0.3μ (7), cured with ultraviolet light, and then heated to a temperature of 150'C1.
It was thermally cured for 30 minutes to form a resist dyeing film. Layers of a transparent dyeable photosensitive resin were successively applied thereon, exposed and developed to form a transparent dyeable image pattern, and dyed first in green and then in blue. Following each dyeing step, a resist film was formed. Green dyeing can be done by immersing in a green acid dye bath consisting of a mixture of Alizarin Green (Tokyo Kasei>10% by weight, 2% by weight of acetic acid and 83% by weight of water) at a temperature of 60'C for 1 hour and 4 minutes. Staining is done with Erio brilliant anthocyanin (
Ciba Geigy) 10% by weight, Ionet D-70 (Sanyo Chemical Industries) 1% by weight, acetic acid 2% by weight and water 87% by weight in a blue acid dye bath at a temperature of 60°C.
This was done by soaking for 2 minutes. When the same test as in Example 1 was conducted using the obtained color filter, even better images were obtained. According to the first and second color filter manufacturing methods of the present invention, there is no step of directly applying the photosensitive resin to the substrate, so there is no possibility that the photosensitive resin will flow out of the substrate during the coating step. There will be no loss. Productivity is high because work can be performed continuously. According to the second color filter manufacturing method of the present invention,
Although dyeing and resist dyeing steps are required, resolution is superior to the first production method, and color density can be increased.
