    摘要: A photocurable/thermosetting composition which is useful for forming a matte film and is developable with an aqueous alkali solution. The composition comprises (A) a photosensitive prepolymer obtained by reacting an (un)saturated polybasic acid anhydride with hydroxyl groups of an ester of a novolak epoxy compound with an unsaturated monocarboxylic acid, (B) a carboxylated copolymer resin, (C) a photopolymerization initiator, (D) a diluent, and (E) a polyfunctional epoxy compound having at least two epoxy groups per molecule and optionally contains (F) an inorganic filler. The composition can further contain (G) a hardener for epoxy resins. This composition is suitable for use in forming a solder resist for printed circuit boards.
