Problems solved by technology

[0006] However, the conventional photosensitive resin composition containing an oxime ester compound as a photopolymerization initiator has a problem that sufficient curing sensitivity cannot be obtained when a colorant is contained in a large amount as in color filter applications.
In addition, when post-heating (post-baking) is performed on the cured film in order to further improve the curability, there is also a problem that unwanted coloring occurs in the cured film.
Undesired coloring in the cured film can cause performance degradation such as brightness reduction, especially when the cured film is applied to a colored pattern of a color filter

Synthetic example 1

[0433] Synthesis Example 1: Synthesis of Alkali-Soluble Resin 1 Having Allyl Group

[0434] 54 g of 1-methoxy-2-propanol was added to a three-neck flask with a capacity of 200 mL equipped with a stirring bar having a stirring blade, a reflux condenser, and a thermometer, and heated to 70° C. under a nitrogen stream. Using a plunger pump, 10.07 g of allyl methacrylate and 1.93 g of methacrylate as a polymerization initiator were dissolved in 54 g of 1-methoxy-2-propanol over 2.5 hours. A solution of 0.185 g of 2,2'-azobis(2,4-dimethylvaleronitrile) was added dropwise into the three-necked flask. After completion of the dropwise addition, it was further stirred at 70° C. for 2 hours. After heating, it was poured into 1 L of water for reprecipitation. The precipitate was filtered and vacuum-dried to obtain 9 g (75% yield) of a polymer compound.

Abstract

The invention provides a dye photosensitive resin composition featuring high harden sensitivity and excellent display and capable of forming dye harden film having excellent heat resistance and expected color tone, a pattern forming method employing the dye photosensitive resin composition, a method for making color filter, a color filter, and a display element having the color filter. The dye photosensitive resin composition at least comprises a colorant, bonding resin, polymerism composition, a photopolymerization starting agent shown in the general formula (I), multifunctional mercaptan composition, and a solvent. In the formula (I), R1 represents a univalent substituent group containing aromatic nucleus or heteromatic nucleus. X1, X2, X3, and X4 independently represent hydrogen atom, halogen atom, or alkyl respectively; Y represents single bond or carbonyl; and Z represents methyl or phenyl.

Description

technical field [0001] The present invention relates to a colored photosensitive resin composition, a pattern forming method, a method for producing a color filter, a color filter, and a display device including the color filter. Background technique [0002] In recent years, the development of liquid crystal display devices has expanded from personal computers or monitors with relatively small screen areas to televisions with large screens and high image quality. [0003] Liquid crystal display devices for televisions require higher image quality, that is, improvements in contrast and color purity, compared to conventional monitor applications. In order to improve contrast, the particle size of the coloring agent (organic pigment etc.) used for the colored photosensitive resin composition for forming a color filter is required to be finer. In addition, in order to improve the color purity, it is required that the content of the coloring agent (organic pigment) in the solid...
