PHOTOPOLYMERIZABLE COMPOSITION

摘要

Disclosed is a photo-cationic-polymerizable composition which has such an excellent photocurable property that the composition can be polymerized and cured rapidly upon being irradiated with a visible light (380 to 500 nm), can shows excellent physical properties when cured, and shows excellent storage stability before being polymerized and cured. The photo-cationic-polymerizable composition essentially comprises (A) 100 parts by weight of a cationic-polymerizable compound (e.g., an epoxy compound), (B) 0.01 to 10 parts by weight of an acid generator comprising an aromatic iodonium salt and/or an aromatic sulfonium salt, (C) 0.01 to 10 partsby weight of a benzoyl compound having a hydroxy group, and (D) 0.01 to 10 parts by weight of thioxanthone-type radical generator.
