| abstract | (57) [Problem] To provide an optical material having a high refractive index, low dispersion, excellent transparency, no optical distortion, and excellent heat resistance. (A) General formula (I) (X and Y are an alkylene group having 1 to 5 carbon atoms or an isocyanate alkyl group (however, the alkyl group has 1 to 3 carbon atoms. Represents an alkylene group having 1 to 5 carbon atoms bonded thereto, and these alkylene groups may have a sulfur atom, and m and n are integers of 1 to 3). From a poly (thio) urethane obtained by polyaddition reaction of a monomer mixture containing a component containing (B) and a component containing a compound having two or more mercapto groups and / or hydroxyl groups in one molecule. Optical material. |
