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 t

Example Embodiment
[0180] Synthesis example 1
[0181] In a flask equipped with a cooling tube and a stirrer, 5 parts by weight of 2,2'-azobisisobutyronitrile and 200 parts by weight of propylene glycol monomethyl ether acetate were added. Next, 50 parts by weight of glycidyl methacrylate and 50 parts by weight of styrene were added, and after replacing with nitrogen, slowly stirring was started. 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.

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 of a 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), R<1>is H or an organic group having a carbon atom abutting to the phosphorus atom; R<2>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 ...
