RESIN AND PHOTOSENSITIVE RESIN COMPOSITION

摘要

The purpose of the present invention is to provide a resin that is capable of producing a photosensitive resin composition having high sensitivity and high film retention ratio. The present invention provides a resin which has a polyamide structure, a polyimide precursor structure or a polyimide structure wherein an acid having an alicyclic structure with 6-40 carbon atoms or a semi-alicyclic structure with 6-40 carbon atoms or an anhydride of the acid is contained in an amount of 5-95% by mole if the total amount of acids or anhydrides thereof is taken as 100% by mole.
