Title:
COMPOUND SUITABLE FOR PHOTOPOLYMERIZATION INITIATOR, PHOTOPOLYMERIZATION INITIATOR, AND PHOTOCURABLE RESIN COMPOSITION
Document Type and Number:
WIPO Patent Application WO/2012/077720
Kind Code:
A1
Abstract:
To provide: a compound, which is suitable for a sealing agent for electronic components or the like, especially suitable for a liquid crystal sealing agent and does not easily generate out gas, and which can be used for a photopolymerization initiator that is photocurable within a visible range; a photopolymerization initiator which contains the compound; and a photocurable resin composition. (1) A compound, which is obtained by having an organic acid compound and/or a hydroxy compound react with a compound that contains at least two epoxy groups in each molecule, said compound being a compound A that is obtained using dimethyl amino benzoic acid as the organic acid compound or being a compound B that is obtained using hydroxythioxanthone as the hydroxy compound. (2) A photopolymerization initiator, which is composed of a photoinitiating compound and a visible light sensitizing compound, and wherein the photoinitiating compound is the compound A and the visible light sensitizing compound is the compound B. (3) A photocurable resin composition which contains a photopolymerizable monomer or oligomer and a photopolymerization initiator set forth in (2).
