Synthetic example 1-1
[0154] Synthesis example 1-1: the synthesis of reactive alkali-soluble resin A'
[0155] Prepare a flask with a stirrer, a thermometer, a reflux condenser, a dropping funnel, and a nitrogen inlet tube, and on the other hand, add 84.2 parts of N-benzylmaleimide, 38.7 parts of methacrylic acid, 22 parts of methyl Tricyclodecanyl acrylate, 4 parts of tert-butyl peroxy-2-ethylhexanoate, and 40 parts of propylene glycol monomethyl ether acetate (hereinafter referred to as "PGMEA") were stirred and mixed to prepare monomer drops. A dropping funnel for a chain transfer agent was prepared by adding 6 parts of n-dodecyl mercaptan and 24 parts of PGMEA and stirring to mix. Thereafter, 395 parts of PGMEA were introduced into the flask, and the atmosphere in the flask was changed from air to nitrogen, and then the temperature of the flask was raised to 90° C. while stirring. Next, the monomer and the chain transfer agent were dropped from the dropping funnel. Dropping was carried out ...

[0156] Synthesis example 1-2: Reactive alkali-soluble resin A' synthesis (A1-a)
[0157] Prepare a flask equipped with a stirrer, a thermometer, a reflux condenser, a dropping funnel, and a nitrogen inlet tube, and on the other hand, add 45 parts of N-benzylmaleimide, 45 parts of methacrylic acid, and 10 parts of methyl Tricyclodecanyl acrylate, 4 parts of tert-butyl peroxy-2-ethylhexanoate, and 40 parts of propylene glycol monomethyl ether acetate (hereinafter referred to as "PGMEA") were stirred and mixed to prepare monomer drops To the funnel, 6 parts of n-dodecylmercaptan and 24 parts of PGMEA were added and stirred to prepare a chain transfer agent dropping funnel. Thereafter, 395 parts of PGMEA were introduced into the flask, and the atmosphere in the flask was changed from air to nitrogen, and then the temperature of the flask was raised to 90° C. while stirring.

Synthetic example 2-1
[0158] Synthesis Example 2-1: Non-reactive alkali-soluble resin A "synthesis
[0159] A flask equipped with a stirrer, a thermometer, a reflux condenser, a dropping funnel, and a nitrogen inlet tube was prepared, and 300 parts of propylene glycol monomethyl ether acetate (PGMEA) was added, stirred and heated to 75°C. 13.7 parts by weight of 3,4-epoxy-8-(acryloyloxy)tricyclo[5.2.1.02,6]decane (EDCPA), 10.9 parts by weight of acrylic acid (AA), 26.5 parts by weight of ethylene A solution of methyltoluene dissolved in 170 parts by weight of PGMEA was dropped into the flask over 5 hours using a dropping funnel. On the other hand, a solution in which 30 parts by weight of the polymerization initiator azobisisobutyronitrile was dissolved in 200 parts by weight of PGMEA was dropped over 5 hours using another dropping funnel. After dropping the polymerization initiator, the temperature was maintained for about 4 hours, and then cooled to room temperature to obtain a resin A″ having...
