CURABLE RESIN COMPOSITION FOR CEMENTED LENSES, IMAGE PICK-UP LENS, AND PROCESS FOR PRODUCITON OF IMAGE PICK-UP LENS

摘要

Provided is a curable resin composition for cemented lenses, whereby it is possible to produce cemented lenses that exhibit excellent heat resistance even when subjected to reflowing treatment at 260°C or higher, and that exhibit excellent tight adhesion between lenses. Further, the curable resin composition can reduce the production cost of lenses and the weight of lenses. The curable resin composition for cemented lenses contains (a) a compound represented by general formula (I) and (b) a radical polymerization initiator. In general formula (I), R1 is a hydrogen atom or an alkyl group; and Z1 together with the two carbon atoms and the sulfur atom represents a ring structure.
