[0106] Production Example 1: Production of Copolymer Represented by Chemical Formula 2

[0107]Put the rhodamine series dye monomer represented by the following chemical formula A and 2-ethylhexyl acrylate monomer into the flask equipped with cooling tube and stirrer according to their respective weight ratios, according to the rhodamine series dye list 8% by weight of the sum of monomer and 2-ethylhexyl acrylate monomer was put into 2,2'-azobis(2,4-dimethylvaleronitrile) initiator. Afterwards, based on 100 parts by weight of the total amount of the initiator and the monomer, 200 parts by weight of propylene glycol methyl ether acetate (PGMEA solvent) was added, and stirring was started slowly under nitrogen atmosphere. The reaction solution was heated to 80° C. and stirred for 8 hours to obtain a copolymer resin represented by the following Chemical Formula 2 containing an aliphatic hydrocarbon. The solid content of the copolymer resin solution obtained by the method describ...

experiment example 1、 comparative example 1、 and comparative example 2

[0115] With the composition described in the following Table 1, after dissolving the photoinitiator in the solvent, it stirred at normal temperature for 2 hours. According to the composition in Table 1, an acrylic binder resin and a photopolymerizable monomer were added, and stirred at room temperature for 2 hours. According to the composition in Table 1, after adding the coloring agent, stir at room temperature for 1 hour, then add surfactant and coupling agent, and stir at room temperature for 1 hour. The prepared solution was filtered three times to remove impurities, and the photosensitive resin compositions of Experimental Example 1, Comparative Example 1, and Comparative Example 2 were produced. When manufacturing the said photosensitive resin composition, the components used are as follows.

Description

technical field [0001] The invention relates to a photosensitive resin composition and a color filter. Background technique [0002] As one of the display devices, the liquid crystal display device has the advantages of light weight, thinner, low price, low power consumption drive, and excellent bonding with integrated circuits. It is used for notebook computers, monitors, and TV images. The scope expanded. Such a liquid crystal display device includes a color filter in which unit pixels formed by integrating red (R), green (G), and blue (B) sub-pixels corresponding to three primary colors of light are repeatedly formed. When the brightness is controlled by applying a color signal to each sub-pixel in a state where each sub-pixel is arranged adjacently, a specified color is displayed in a unit pixel by combining three primary colors. [0003] The color filter is made of red (R), green (G), blue (B) dyes or pigments, and this pigment material plays the role of converting th...
