Problems solved by technology

Therefore, when forming a resin film pattern, a colored film pattern, and a light-shielding film pattern on a plastic substrate or a device, there is a problem that the film strength of the pattern formed at a thermal firing temperature of 140° C. (For example, in the case of a light-shielding film pattern, solvent resistance at the time of coating each RGB resist, alkali resistance at the time of alkali development, etc.), defects such as film reduction of the coating film, surface roughness, and pattern peeling may occur.
However, in the case of forming a resin film pattern at a low temperature on a plastic substrate with low heat resistance or a substrate with an organic device, etc., it is still insufficient. A photosensitive resin composition having excellent resin film patterns such as solvent resistance and alkali resistance

[0083] Impregnate 1 g of the resin solution obtained in the synthesis example into a glass filter [weight: W0 (g)] and weigh [W1 (g)]. According to the weight [W2 (g) after heating at 160°C for 2 hours ] and calculated using the following formula.

[0084] Solid content concentration (% by weight)=100×(W2-W0) / (W1-W0...

Synthetic example 1

[0110] 300 g of PGMEA was charged in a 1 L four-necked flask with a reflux cooler, and the inside of the flask system was replaced with nitrogen, and then the temperature was raised to 120°C. In the said flask, the monomer mixture (made by dissolving 10 g of AIBN in 77.1 g (0.35 mol) of DCPMA, 49.8 g (0.35 mol) of GMA, 31.2 g (0.30 mol) of St. mixture), and then stirred at 120° C. for 2 hours to obtain a copolymer solution.

[0111] Next, after replacing the inside of the flask system with air, 24.0 g of AA (95% of the glycidyl group), 0.8 g of TDMAMP, and 0.15 g of HQ were added to the obtained copolymer solution, and stirred under heating at 120° C. for 6 hr to obtain a solution containing Copolymer solutions of polymerizable unsaturated groups.

[0112] Furthermore, 30.0 g of SA (90% of the number of moles of AA added) and 0.5 g of TEA were added to the obtained polymerizable unsaturated group-containing copolymer solution, and reacted at 120° C. for 4 hours to obtain a po...
