ULTRAVIOLET CURING TYPE RESIN COMPOSITION

摘要

PURPOSE:To provide a low-viscosity resin composition easily cured by irradiation with active energy rays and soluble and peelable by alkali, and especially, to provide the ultraviolet curing type resin composition superior as a resin composition used for an etching resist. CONSTITUTION:This ultraviolet curing type resin composition is characterized by comprising a compound having one carboxylic group and one acryloyl or methacryloyl group in one molecule; a compound having >=2 acryloyl or methacryloyl group in one molecule; a leveling agent; and a tertiary amine photoinitiator and/or a thioxantone type photoinitiator, and having a viscosity of <=5000cps at 25 deg.C.
