Document Type and Number:
Japanese Patent JP5063025
Kind Code:
B2
Abstract:
An object of the present invention is to provide a deep-ultraviolet-transmitting epoxy resin cured product having high heat resistance and high resistance to deep-ultraviolet light, and to provide a curing accelerator and an epoxy resin composition which are used for producing the epoxy resin cured product. The curing accelerator for deep-ultraviolet-transmitting epoxy resins comprises a tetraalkylphosphonium dialkyl phosphate represented by the following general formula (1): wherein R1, R2, R3, R4, R5, and R6 each represent an alkyl group or an alkyl group having a hydroxyl group, which has 1 to 8 carbon atoms and is linear, branched, or alicyclic; and R1, R2, R3, R4, R5, and R6 may be the same or different.
