Synthetic example 1

[0247] In a flask equipped with a condenser and a stirrer, dissolve 70.0 g of 3-acryloyloxymethyl-3-ethyloxetane, 15.0 g of acrylic acid and 15.0 g of ω-carboxypolycaprolactone monoacrylate To 300 g of propylene glycol monomethyl ether acetate, 3.0 g of 2,2'-azobisisobutyronitrile and 5.0 g of α-methylstyrene dimer were added, and then purged with nitrogen for 15 minutes. After purging with nitrogen gas, the reaction solution was heated at 80° C. while stirring and bubbling nitrogen gas, and polymerized for 5 hours to obtain a solution containing 25% by weight of the precursor copolymer [b-1]. The polystyrene conversion weight average molecular weight (Mw) of this precursor copolymer [b-1] was 10000.

Synthetic example 2～9

[0249] Except that the types and amounts of compound (b1), compound (b2), compound (b4) and compound (b6) which are polymerizable unsaturated compounds, polymerization initiators, chain transfer agents, and molecular weight modifiers are as shown in Table 1 , were carried out in the same manner as in Synthesis Example 1 above to obtain solutions containing 25% by weight of the precursor copolymers [b-2] to [b-9].

[0250] Table 1 shows the polystyrene-equivalent weight average molecular weight (Mw) of the precursor copolymer produced in each synthesis example.

Synthetic example 10

[0254] 200 g of the solution containing the precursor copolymer [b-1] prepared in Synthesis Example 1 above, 25.6 g of glycidyl methacrylate as compound (b5), and 4-methoxyphenol as a polymerization inhibitor 0.2 g and 2.5 g of tetrabutylammonium bromide as a catalyst were put into the flask, and it was made to react at the temperature of 110 degreeC for 9 hours. This reaction liquid was washed with water four times with 75 g of ion-exchanged water each time, and concentrated under reduced pressure to obtain a solution containing 33% by weight of the polymer [B-1]. The polystyrene-equivalent weight average molecular weight (Mw) of polymer [B-1] was 11,500, the oxetanyl group content was 2.8 mmol / g, and the polymerizable unsaturated bond content was 1.8 mmol / g.

Abstract

The invention relates to a radiation-sensitive linear composition for forming coloured layer, a colour filter and a colour liquid crystal display device. A radiation-sensitive linear composition for forming coloured layer is provided, which is able to forming pixel and black matrix with enough developing resistance and excellent solvent resistance even if in a low exposure quantity. The radiation-sensitive linear composition for forming coloured layer is characterized in that it contains (A) colouring agent, (B) polymer comprising oxygen heterocyclic butyl and polymerized unsaturated bond, and (C) photopolymerization initiator.

Description

technical field [0001] The present invention relates to a radiation-sensitive composition for forming a colored layer, a color filter, and a liquid crystal display element, and more specifically, to a color filter used in a transmissive or reflective color liquid crystal display device, a color pickup tube element, etc. A radiation-sensitive composition for forming a colored layer, a color filter having a colored layer formed using the radiation-sensitive composition, and a color liquid crystal display element having the color filter. Background technique [0002] As a method of forming a color filter using a colored radiation-sensitive composition, it is known to form a coating film of a colored radiation-sensitive composition on a substrate or a substrate on which a desired pattern-shaped light-shielding layer is formed in advance, by having a desired pattern. A photomask is irradiated with radiation (hereinafter referred to as "exposure"), developed to dissolve and remove...
