2,3-(BIS)ARYLTHIO-1,4-NAPHTHALENEDIOL DI(2'-ALKYL)ACRYLATE COMPOUNDS, METHOD FOR PRODUCING THE SAME, POLYMER OBTAINED FROM THE DI(2'-ALKYL)ACRYLATE COMPOUNDS AND POLYMER FOR OPTICAL PART

摘要

PROBLEM TO BE SOLVED: To provide a new monomer for producing resins having high refractive indexes and capable of being used for members such as lenses, prism sheets for LCD, light guide plates and diffusion sheets. SOLUTION: This 2,3-(bis)arylthio-1,4-naphthalenediol di(meth)acrylate compound represented by the general formula (1) (R1and R2are each independently H or a 1 to 4C alkyl; R3and R4are each independently a monovalent aromatic group which may have a substituent, or -R3-R4- formed by connecting R3to R4is a divalent group which has at least one aromatic ring and in which S is directly bound to the aromatic ring).
