| titleOfInvention | Thermoplastic resin for lenses, and lens comprising same |
| abstract | The present invention provides a thermoplastic resin for lenses, which enables the expansion of the range of variations of lens type so that an imaging lens designer can choice a lens among from various types of lenses. The thermoplastic resin for lenses according to the present invention has both of a first structural unit derived from a dihydroxy compound represented by formula (1) (wherein R 1 , R 2 , R 3 and R 4 independently represent any one selected from a hydrogen atom, an alkyl group having 1 to 10 carbon atoms, an alkoxy group having 1 to 10 carbon atoms, a cycloalkyl group having 3 to 20 carbon atoms, a cycloalkoxy group having 6 to 20 carbon atoms, an aryl group having 6 to 10 carbon atoms, an aralkyl group having 7 to 20 carbon atoms, an aryloxy group having 6 to 10 carbon atoms, an aralkyloxy group having 7 to 20 carbon atoms and a halogen atom; and the cyclobutane ring represents any one of a mixture of a cis-isomer thereof and a trans-isomer thereof, a cis-isomer thereof alone, and a trans-isomer thereof alone), and a second structural unit derived from a dihydroxy compound or a dicarboxylic acid compound, and also has a refractive index (n D ) and an Abbe's number (ν) which satisfy mathematical formula (A): n D < 1.156×10 -4 ×ν 2 –1.289×10 -2 ×ν+1.853 (A). |
