Problems solved by technology

[0006] Therefore, it is conceivable that by adding an amine compound used as a curing agent for epoxy-based materials, the crosslinking reaction will proceed even at low temperatures, but adding a general amine compound may cause a reaction with the epoxy group present in the composition. Time-dependent reaction occurs, which reduces storage stability

[0182]

[0183] In the radiation-sensitive resin composition of the present invention, in addition to mixing [A] an alkali-soluble resin, [B] a polymerizable compound, [C] a radiation-sensitive polymerization initiator, and [D] a blocked isocyanate compound, if necessary, Optional ingredients are mixed in prescribed ratios to be prepared. This radiation-sensitive resin composition is preferably used in a solution state by being dissolved in an appropriate solvent.

[0184] As the solvent used in the preparation of the radiation-sensitive resin composition, one that can uniformly dissolve or disperse the components but does not react with the components can be used. Examples of the solvent include the same ones as those exemplified as solvents usable for the synthesis of the above-mentioned [A] alkali-soluble resin. The solvent may be used alone or in combination of two or more.

Synthetic example 1

[0234] In a flask with a condenser and a stirrer, 7 parts by mass of 2,2'-azobis(2,4-dimethylvaleronitrile) and 200 parts by mass of diethylene glycol ethyl methyl ether were added. Then add 16 parts by mass of methacrylic acid as (A1) compound, 20 parts by mass of 2-hydroxyethyl methacrylate as (A2) compound, 10 parts by mass of glycidyl methacrylate as (A3) compound and 16 parts by mass of methacrylic acid tricyclo[5.2.1.0 as (A4) compound 2，6 ]dec-8-yl ester, 28 parts by mass of methyl methacrylate and 10 parts by mass of styrene, after being replaced with nitrogen, slowly stirred, and the solution was warmed up to 70°C, and kept at this temperature for 4 hours to carry out polymerization, thereby obtaining A solution of a copolymer (A-1) (solid content concentration=34.4% by mass, Mw=8000, Mw / Mn=2.3). In addition, the solid content concentration refers to the ratio of the copolymer mass to the total mass of the copolymer solution.

Abstract

The invention relates to a radiation-sensitive resin composition, a cured film, a cured film forming method, a color filter and a color filter forming method. Specifically, the invention aims to provide a radiation-sensitive resin composition which is stable in storage and sufficient in sensitivity and can be roasted at a low temperature, a cured film which achieves excellent solvent resistance, relative dielectric constant and hardness and serves as an interlayer insulating film, a protective film or a gasket, a cured film forming method, a color filter which is excellent in heat resistance, solvent resistance, voltage holding ratio, etc., and a color filter forming method. The radiation-sensitive resin composition of the invention comprises an alkali soluble resin [A], a polymerizable compound [B] having ethylene unsaturated bonds, a radiation-sensitive polymerization initiator [C] and a blocked isocyanate compound [D].

Description

technical field [0001] The present invention relates to a radiation-sensitive resin composition, a cured film, a method for forming a cured film, a color filter, and a method for forming a color filter. Background technique [0002] Radiation-sensitive resin compositions are being widely used as materials for forming cured films of interlayer insulating films, protective films, or spacers. As such a radiation-sensitive resin composition, for example, a composition containing a copolymer composed of an unsaturated carboxylic acid, an epoxy group-containing unsaturated compound, or the like is known (see JP-A-2001-354822). However, when using these compositions, in order to increase the surface hardness and satisfy the cured film to meet the level required by practical business, it is necessary to undergo a firing process at a high temperature above 200°C. [0003] On the other hand, flexible displays such as e-books are gaining popularity. As a substrate for this flexible d...
