[0064] An embodiment of the production method of the alkali-soluble resin will be described below.
[0065] Add the aforementioned monomer, the solvent relative to the monomer content of 0.5 to 20 times, and the polymerization initiator relative to the molar amount of the monomer of 0.1% to 10% to be equipped with a stirrer, a thermometer, a reflux cooling pipe, a titration device and Nitrogen was introduced into the flask in line and subsequently replaced with nitrogen. Then, it was stirred at 40°C to 140°C for 1 hour to 10 hours.
[0066] The above-mentioned solvent used herein can be any common solvent used for free radical polymerization, for example, it includes: selected from tetrahydrofuran, dioxane, dimethyl ethyl glycol, dimethyl ethyl diethylene glycol Alcohol, acetone, methyl ethyl ketone, methyl isobutyl ketone, cyclohexanone, ethyl acetate, butyl acetate, propylene glycol monomethyl ethyl acetate, 3-methoxybutyl acetate, methanol, Any of ethanol, propanol, n-but...
