Abstract
(EN)
The present invention addresses the problem of providing a novel optical resin that retains favorable optical properties such as high refractive index, and at the same time has superior moldability that prevents molding defects from occurring. This problem is solved by an optical resin composition for lenses that contains a resin having a structural unit represented by formula (1), and a binaphthalene compound and/or a binaphthalene compound oligomer having a structural unit represented by formula (2). A, p, K1, K2, Z, and q in formula (1) are as described in the present specification. R1-R10, a, and b in formula (2) are as described in the present specification.

La présente invention aborde le problème consistant à fournir une nouvelle résine optique qui conserve des propriétés optiques favorables telles qu'un indice de réfraction élevé, et qui simultanément présente une moulabilité supérieure, qui empêche l'apparition de défauts de moulage. Ce problème est résolu par une composition de résine optique pour des lentilles, qui contient une résine ayant un motif structural représenté par la formule (1), et un composé binaphtalène et/ou un oligomère d'un composé binaphtalène ayant un motif structural représenté par la formule (2). A, p, K1, K2, Z, et q dans la formule (1) sont tels que décrits dans la présente invention. R1-R10, a, et b dans la formule (2) sont tels que décrits dans la présente invention.
