Problems solved by technology

[0008] However, the crosslinkable color photosensitive ink used in the inkjet process does not need to be developed, but the adhesion to the substrate, mechanical strength and physical and chemical properties still need to meet certain conditions
Therefore, general inkjet inks include polymer resins and other cross-binder components. However, from the perspective of ink stability, adding polymer resins to photosensitive inks, the more ingredients are added, the more complex the formula, and the long-term stability more difficult to achieve

Embodiment Construction

[0019] Several embodiments of the present invention will be further described in detail below.

[0020] The invention provides a kind of color filter ink-jet ink, and its composition comprises: 0.1 to 40wt% colorant, 1 to 95wt% solvent, 0.01 to 15wt% initiator and 0.5 to 80wt% polymer oligomer substances or their modifications.

[0021] Preferably, the optimum weight ratio range of the colorant is 3-15wt%.

[0022] Preferably, the optimum weight ratio range of the solvent is 25-85wt%.

[0023] Preferably, the optimal weight ratio range of the polymer oligomer or its modified product is 3-65 wt%.

[0024] Preferably, the optimum weight ratio range of the initiator is 0.1-8wt%.

[0025] Wherein, the coloring material includes dyes, pigments or other coloring substances. The colorant is preferably a pigment. Common red pigments include: Pigment Red 122, Pigment Red 177, Pigment Red 185, Pigment Red 202, Pigment Red 206, Pigment Red 207, Pigment Red 209, Pigment Red 224, Pigm...

Abstract

This invention relates to a color filter ink-jet ink, comprising: 0.1-40%wt coloring material, 1-95%wt solvent, 0.01-15%wt initiator, and 0.5-80%wt high molecular oligomer or modified compound thereof. This invention replaces the macromolecular resin and organic monomer material with appropriate amount of high molecular oligomer or modified compound thereof, so as to obtain the color filter ink-jet ink with crosslinking property and high stability.

Description

【Technical field】 [0001] The invention relates to a color filter ink-jet ink, in particular to a cross-linked filter ink-jet ink. 【Background technique】 [0002] Since the liquid crystal display (Liquid Crystal Display, LCD) is a non-active light-emitting component, the light source must be provided through the internal backlight, and the driver IC and LCD control are used to form a black and white grayscale display, and then through the color filter The red (R), green (G), and blue (B) color layers of the color filter provide hue and form a color display screen, so the color filter is a key component of the colorization of the liquid crystal display. [0003] At present, the manufacturing methods of color filters in the prior art mainly include: Pigment-dispersed Method and Ink Jet Method. [0004] The pigment dispersion method is to apply the color photoresist (Color Resist) on the substrate by spin coating, and prepare a color block (Color Area) through exposure and deve...
