Document Type and Number:
WIPO Patent Application WO/2021/193878
Kind Code:
A1
Abstract:
This novolac resin has a partial structure represented by -C(CF3)H-. This photosensitive resin composition contains the novolac resin and a photosensitizer. This epoxy resin has a partial structure represented by -C(CF3)H-. This curable resin composition contains the novolac resin or the epoxy resin. This cured product is obtained by curing the composition. In this method for producing a novolac resin, a novolac resin having a partial structure represented by -C(CF3)H- is produced by reacting an aromatic compound and fluoral in the presence of an acid catalyst. This method for producing an epoxy resin includes an epoxidation step in which a novolac resin having a partial structure represented by -C(CF3)H- is reacted in the presence of an epihalohydrin and a base.
