)且Z₁係單鍵。而如式(IIIb)至式(IIIh)所示之化合物係以相同方法製備，但選用適合的肟來進行。 The oxime ester represented by the formula (III) is prepared by a conventional method, for example, by reacting the corresponding oxime with an acyl halide, especially chloride or acid anhydride under the following conditions: in an inert solvent (eg: third Butyl methyl ether, tetrahydrofuran (THF) or dimethylformamide), in the presence of a base (such as triethylamine or pyridine), or in a basic solvent (such as pyridine). In one embodiment of the present invention, the compound of formula (IIIa) is prepared by the method shown in formula (i) below, wherein E ₇ is an oxime ester group (

The acid anhydride reacts to produce a compound of formula (III) as defined above, wherein X is a halogen atom, and particularly a chlorine atom, and the definition of E14 is as previously described.

The oxime required as a starting material can be obtained through standard chemistry textbooks (eg J. March, Advanced Organic Chemistry, 4th Edition, Wiley Interscience, 1992) or monographs (eg SRSandler & W. Karo, Organic functional group preparations, 3 volumes, Academic Press).

One of the most convenient methods is, for example, to react aldehyde or ketone with hydroxylamine or its salt in a polar solvent (such as dimethylacetamide (DMA), DMA aqueous solution, ethanol or ethanol aqueous solution). In this case, a base such as sodium acetate or pyridine is added to control the pH of the reaction mixture. It is well known that the reaction rate is pH dependent, and the base can be added continuously at the beginning or during the reaction. Basic solvents such as pyridine can also be used as bases and/or solvents or co-solvents. The reaction temperature is usually from room temperature to the reflux temperature of the mixture, generally from about 20°C to 120°C.

The corresponding ketone intermediate system (for example) is prepared by the method described in the literature (for example standard chemistry textbooks, for example J. March, Advanced Organic Chemistry, 4th edition, Wiley Interscience, 1992). In addition, the continuous Friedel-Crafts reaction can be effectively used to synthesize intermediates. These reactions are well known to those skilled in the art.

Another convenient synthesis of oximes is the nitrosation of "active" methylene with nitrous acid or alkyl nitrite. Alkaline conditions (such as (for example) Organic Syntheses coll. Volume VI (J. Wiley & Sons, New York, 1988), pages 199 and 840) and acidic conditions (such as (for example) Organic Synthesis coll . Volume V, pages 32 and 373, coll. Volume III, pages 191 and 513, coll. Volume II, pages 202, 204 and 363) both It is suitable for preparing oximes used as starting materials in the present invention. Nitrous acid is generally produced from sodium nitrite. The alkyl nitrite may be, for example, methyl nitrite, ethyl nitrite, propyl nitrite, butyl nitrite, or isoamyl nitrite.

The invention also provides a color filter, which is made by the aforementioned method.

The manufacturing method of the color filter of the present invention mainly uses the coating methods such as spin coating, cast coating, ink-jet coating or roll coating to mix the foregoing into a solution state. The photosensitive composition for the color filter is coated on the substrate. After coating, most of the solvent is removed by drying under reduced pressure, and then the solvent is removed by a pre-bake method to form a pre-baked coating film. Among them, the conditions of reduced-pressure drying and pre-baking vary according to the types of ingredients and the mixing ratio. Generally, reduced-pressure drying is performed under a pressure of 0 to 200 mmHg for 1 to 60 seconds, while pre-baking is It is carried out at a temperature of 70 to 110°C for 1 to 15 minutes. After pre-baking, the pre-baking coating film is exposed to a designated mask, immersed in a developing solution at a temperature of 23±2°C for 15 seconds to 5 minutes for development, and the unnecessary parts are removed to form a pattern. The light used for exposure is preferably ultraviolet rays such as g-line, h-line, i-line, etc., and the ultraviolet device may be (ultra) high-pressure mercury lamp or metal halogen lamp.

Specific examples of the aforementioned substrates are: alkali-free glass used for liquid crystal display devices, soda lime glass, hard glass (Pales glass), quartz glass, soda glass, and transparent conductive films attached to these glasses; or Photoelectric conversion device substrates (such as silicon substrates) for solid-state imaging devices, etc. These substrates generally form a black matrix that separates the colored layers of each pixel.

When using the developer composed of the aforementioned alkaline aqueous solution, it is generally washed with water after development, followed by compressed air or compressed nitrogen to dry the pattern.

After air-drying, the substrate with the photo-curable coating film layer is heated at a temperature of 100 to 280°C for 1 to 15 minutes using a heating device such as a hot plate or an oven to remove volatile components from the coating film The reacted ethylenically unsaturated double bond undergoes a thermal hardening reaction. Using the photosensitive resin composition of each color (mainly including three colors of red, green, and blue) and repeating the operation three times in the same steps on a predetermined pixel, a pixel colored layer of three colors of red, green, and blue can be obtained.

Next, on the pixel colored layer, an ITO (indium tin oxide) vapor-deposited film is formed under vacuum at a temperature of 220° C. to 250° C. If necessary, after etching and wiring are performed on the ITO vapor-deposited film, a polymer for liquid crystal alignment film is coated. Acetylene imide, and then fired, can be used as a color filter for liquid crystal displays.

Then, it is dried under reduced pressure for about 30 seconds under a pressure of about 100 millimeters of mercury (mmHg). Next, the above glass substrate was prebaked at 80°C for 2 minutes to form a prebaked coating film with a film thickness of 2.5 microns. After irradiating the pre-baked coating film with an ultraviolet light (exposure machine Canon PLA-501F) of 100 mJ/cm ² , the pre-baked coating film was immersed in a developer (0.04% potassium hydroxide) at 23° C. for 60 seconds. In order to remove the part of the pre-baked coating film which is not irradiated with ultraviolet light. Finally, after washing with pure water, post-baking treatment is carried out in an oven at 235°C for 30 minutes to obtain a pixel pattern. Next, the gradient angle of the pixel pattern (the angle between the glass substrate and the pattern) was observed with a scanning electron microscope (manufactured by Hitachi, model S-3000N). The evaluation method is shown in Table 4: The evaluation criteria for the gradient angle are as follows.
