Problems solved by technology

[0004] On the other hand, by using a high-boiling-point solvent in combination with the radiation-sensitive resin composition for forming the colored layer, the generation of dry matter can be suppressed, but it is difficult to fully evaporate, and the generation of stickiness and the prolonged time of vacuum baking lead to a decrease in productivity. reduce
In addition, there is also the following problem: due to the selection and addition amount of the high-boiling point solvent, when the solvent evaporates through the process of vacuum baking after coating the radiation-sensitive resin composition, microscopic air bubbles contained in the composition appear on the coating film. On the surface, after drying, the original notch (クレ-タ-)-shaped defect (hereinafter referred to as "bump hole (bump hole)") remains

Embodiment 1

[0281] Hereinafter, the present invention will be described in more detail with reference to examples, but the present invention is not limited to the following examples.

[0282] (A) 15 parts by weight of a mixture of C.I. Pigment Red 254 / C.I. Pigment Red 177=80 / 20 (weight ratio) as a colorant, 4 parts by weight of Disperbyk-2001 (in terms of solid content) as a dispersant, and (B) Methacrylic acid / N-phenylmaleimide / styrene / benzyl methacrylate copolymer (copolymerization weight ratio=20 / 30 / 20 / 30, Mw=9500, Mn=5000) 6 parts by weight and 75 parts by weight of propylene glycol monomethyl ether acetate as a solvent (E) were treated with a bead mill to prepare a pigment dispersion (R1).

[0283] Next, 100 parts by weight of the pigment dispersion liquid (R1), methacrylic acid / succinic acid mono[2-methacryloyloxyethyl] ester / N-phenylmaleic acid as (B) alkali-soluble resin Imide / styrene / benzyl (meth)acrylate copolymer (copolymerization weight ratio=25 / 10 / 30 / 20 / 15, Mw=12000, Mn=6500...

Embodiment 2

[0308] Except that the (E) solvent added to 100 parts by weight of the pigment dispersion (R1) in Example 1 was changed to 50 parts by weight (20 weight %) of cyclohexyl acetate and 125 parts by weight of ethyl 3-ethoxypropionate Except (50 weight part), it carried out similarly to Example 1, the composition (R1-2) for coloring layer formation was prepared, and it evaluated again. Moreover, the (E) solvent in the composition (R1-2) for coloring layer formation contained 75 weight part (30 weight%) of propylene glycol monomethyl ether acetate further. The evaluation results are shown in Table 1.

Embodiment 3

[0310] In addition to changing the (E) solvent added to 100 parts by weight of the pigment dispersion (R1) in Example 1 to 50 parts by weight (20% by weight) of cyclohexyl acetate, 50 parts by weight (50 parts by weight) of propylene glycol monomethyl ether acetate % by weight), 25 parts by weight of diethylene glycol methyl ethyl ether (10% by weight) and 50 parts by weight of 3-methoxybutyl acetate (20% by weight), operate in the same manner as in Example 1 to prepare the colored layer Formation composition (R1-3) was evaluated. The evaluation results are shown in Table 1.

Abstract

A radiation sensitive resin composition for forming a colored layer, comprising (A) a colorant, (B) an alkali-soluble resin, (C) a polyfunctional monomer, (D) a radiation sensitive radical generator and (E) a solvent, wherein the component (D) comprises an oxime type radical generator, and the component (E) contains 5 to 40 wt% of cyclohexyl acetate or dipropylene glycol dimethyl ether. This radiation sensitive resin composition has high solvent re-solubility of a dried product thereof formed in a slit nozzle portion, can suppress the formation of a bumping hole and has high sensitivity.

Description

technical field [0001] The present invention relates to a radiation-sensitive resin composition for forming a colored layer, a method for forming the colored layer, a color filter, and a color liquid crystal display element. Specifically, it relates to a radiation-sensitive resin composition used in forming a colored layer useful for color filters used in the manufacture of transmissive or reflective color liquid crystal display devices, color imaging tube elements, and the like, and combinations using radiation-sensitive resins. A method for forming a colored layer of an object, a color filter having a colored layer, and a color liquid crystal display element provided with a color filter. Background technique [0002] It is conventionally known to obtain pixels of each color by using a radiation-sensitive resin composition for forming a colored layer to manufacture a color filter, usually, on a substrate or a substrate on which a light-shielding layer of a desired pattern i...
