Problems solved by technology

[0007] In the formation of such a protective film, it is convenient to use a thermosetting composition that has the advantage that a protective film excellent in hardness can be formed by a simple method, but a protective film resin that exhibits the above-mentioned various characteristics Compositions have highly reactive crosslinking groups or catalysts that allow them to form strong crosslinks, so there is a problem that the shelf life of the composition itself is very short, and handling is very troublesome
That is to say, not only the coating performance of the composition itself deteriorates with time, but also the coating machine must be frequently maintained, cleaned, etc., which is cumbersome to operate.
[0008] A material that can easily form a protective film that satisfies the general requirements of protective films such as transparency and satisfies the above-mentioned various properties, and has excellent storage stability as a composition has not yet been known.
[0009] In addition, Patent Document 3 discloses a thermosetting composition including latent carboxyl compounds used in paints, inks, adhesives, and molded articles, but does not disclose anything about color filter protective films.

Synthetic example

[0178] Hereinafter, the present invention will be described more specifically by illustrating synthesis examples and examples, but the present invention is not limited to the following examples.

[0179] Copolymer Manufacture

Synthetic example 1

[0181] In the flask equipped with cooling tube and stirrer, add 5 parts by weight of 2,2'-azobisisobutyronitrile, 200 parts by weight of propylene glycol monomethyl ether acetate. Next, 50 parts by weight of glycidyl methacrylate and 50 parts by weight of styrene were added, and after replacing with nitrogen gas, stirring was started slowly. The temperature of the solution was raised to 70° C., and the temperature was maintained for 5 hours to obtain a polymer solution containing a copolymer (A-1). The solid content concentration of the obtained polymer solution was 32.9% by weight.

Synthetic example 2

[0183] In the flask equipped with cooling tube and stirrer, add 5 parts by weight of 2,2'-azobisisobutyronitrile, 200 parts by weight of propylene glycol monomethyl ether acetate. Next, 50 parts by weight of (3-ethyl-3-oxyethyl) methyl methacrylate and 50 parts by weight of styrene were added, replaced with nitrogen, and then slowly stirred. The temperature of the solution was raised to 70° C., and the temperature was maintained for 5 hours to obtain a polymer solution containing a copolymer (A-2). The solid content concentration of the obtained polymer solution was 33.2% by weight.

Abstract

A a resin composition is provided forming a highly flat cured film even on a substrate with low flatness surface, suitable for forming a protecting film for optical device excellent in transparency, surface hardness, various resistance characteristics such as resistance to heat and pressure, alkali resistance and resistance to sputtering. The resin composition comprises (A) 100 parts by weight ofa copolymer comprising (a1) a polymerizable unsaturated compound containing an oxiranyl group or an oxetanyl group and (a2) a polymerizable unsaturated compound excluding the compound of (a1), and (B) 0.01-50 parts by weight of a phosphate based ester represented by formula (1). X is an integer of 0-2 in the formula (1), R1 is H or an organic group having a carbon atom abutting to the phosphorusatom; R2 is an organic group having a carbon atom abutting to the oxygen atom.

Description

technical field [0001] The present invention relates to a resin composition, a method for forming a color filter protective film from the resin composition, and a color filter protective film. More specifically, it relates to a resin composition suitable as a material for forming a protective film used in a color filter for a liquid crystal display (LCD) and a color filter for a charge-coupled device (CCD), and a protective film using the resin composition Method and protective film formed from the composition. Background technique [0002] Radiation devices such as LCDs and CCDs are dipped in solvents, acids, or alkali solutions during their manufacturing process, and when wiring electrode layers are formed by sputtering, the surface of the elements is locally exposed to high temperatures. Then, in order to prevent deterioration or damage of elements due to such treatments, a protective film formed of a thin film resistant to these treatments is provided on the surface of ...
