Problems solved by technology

[0004] In the color filter film-forming process using the photosensitive resin composition, the photosensitive resin composition should be cured by ultraviolet light, and when using the existing photosensitive resin composition, especially those containing blue, green or black pigments When using a photosensitive resin composition, since the photosensitive resin composition has a strong absorption of ultraviolet light, the exposure energy of the required ultraviolet light is high, and the utilization rate of ultraviolet light is low.

Embodiment 2

[0050] The components of the photosensitive resin composition of this embodiment refer to the data of Example 2 in Table 1, specifically: 6% of pigment, 2.5% of dispersant, 2% of dispersed resin, 1% of reflective particles, 67.4% of solvent, photoactive polymerization 10% of compound, 8% of photoactive monomer, 2.5% of epoxy resin, 0.45% of photoinitiator, and 0.15% of additive, wherein the above percentages are all percentages by weight.

Embodiment 3

[0052] The components of the photosensitive resin composition of this embodiment refer to the data of Example 3 in Table 1, specifically: 8% of pigment, 4% of dispersant, 2.4% of dispersed resin, 1.5% of reflective particles, 60.07% of solvent, photoactive polymerization 12% of compound, 8% of photoactive monomer, 1.8% of epoxy resin, 2% of photoinitiator, and 0.23% of additive, wherein the above-mentioned percentages are all percentages by weight.

[0053] Embodiment 4 of the photosensitive resin composition of the present invention

[0054] The components of the photosensitive resin composition of this embodiment refer to the data of Example 4 in Table 1, specifically: 8% of pigment, 4% of dispersant, 2.4% of dispersed resin, 2% of reflective particles, 55.65% of solvent, photoactive polymerization 15% of compound, 8% of photoactive monomer, 2.5% of epoxy resin, 2% of photoinitiator, 0.45% of additive, wherein the above-mentioned percentages are all percentages by weight.

Embodiment 7

[0093] The content of pigment in the photosensitive resin composition of embodiment 7 and embodiment 8 is greater than the content of pigment in embodiment 5 and embodiment 6, but because the content of reflective particles in embodiment 7 and embodiment 8 is much greater than embodiment 5 and embodiment The content of reflective particles in Example 6, so the ultraviolet light exposure energy required by the photosensitive resin composition of Example 7 and Example 8 is less than that required by Example 5 and Example 6.

Description

technical field [0001] The invention relates to liquid crystal display manufacturing technology, in particular to a photosensitive resin composition and a preparation method thereof. Background technique [0002] With the rapid popularization of color liquid crystal displays in the market, the requirements for color display of liquid crystal displays continue to increase. High color saturation and high transmittance are one of the important indicators for evaluating liquid crystal displays. Color filters are the key components for liquid crystal displays to realize color display, and the production technology of color filters is constantly updated and tends to be diversified. [0003] The performance of the color filter is mainly determined by the performance of the colored photosensitive resin composition and the film-forming process of the color filter. In order to ensure the heat resistance, chemical corrosion resistance and other properties in the process of making the ...
