Claim Text:
1. An eyewear material comprising a polyurethane resin produced by allowing a polyisocyanate component to react with an active hydrogen group-containing component, wherein the polyisocyanate component comprises: a 1,4-bis(isocyanatomethyl)cyclohexane composition containing a 1,4-bis(isocyanatomethyl)cyclohexane and a compound represented by formula (1) below, the 1,4-bis(isocyanatomethyl)cyclohexane containing a trans isomer of 1,4-bis(isocyanatomethyl)cyclohexane and a cis isomer of 1,4-bis(isocyanatomethyl)cyclohexane, and comprising 70 mol % or more and 95 mol % or less of the trans isomer relative to a total amount of the cis isomer and the trans isomer, and the 1,4-bis(isocyanatomethyl)cyclohexane composition containing 0.1 ppm or more and 300 ppm or less of the compound represented by formula (1) below: and/or a polyisocyanate-modified composition produced by modifying the 1,4-bis(isocyanatomethyl)cyclohexane composition and containing at least one functional group of (a) to (e) below: (a) an isocyanurate group obtained by trimerizing the 1,4-bis(isocyanatomethyl)cyclohexane, (b) an allophanate group obtained by allowing the 1,4-bis(isocyanatomethyl)cyclohexane and a monoalcohol to react, and then further subjecting them to an allophanate-forming reaction, (c) a biuret group obtained by allowing the 1,4-bis(isocyanatomethyl)cyclohexane to react with at least one selected from the group consisting of water, tertiary alcohol and secondary amine, and then further subjecting them to a biuretization reaction, (d) a urethane group obtained by allowing the 1,4-bis(isocyanatomethyl)cyclohexane to react with a polyol component, and (e) a urea group obtained by allowing the 1,4-bis(isocyanatomethyl)cyclohexane to react with water and/or a polyamine component.
