First claim
Opening claim text (preview).
The invention claimed is: 1. A xylylenediisocyanate composition comprising xylylenediisocyanate and a compound represented by Chemical Formula (1) below, wherein 0.6 ppm or more and 60 ppm or less of the compound represented by Chemical Formula (1) below is contained: 2. The xylylenediisocyanate composition according to claim 1 further comprising chloromethyl benzyl isocyanate, wherein the chloromethyl benzyl isocyanate content is 0.2 ppm or more and 3000 ppm or less. 3. The xylylenediisocyanate composition according to claim 2 , wherein the chloromethyl benzyl isocyanate content is 0.2 ppm or more 1600 ppm or less. 4. A xylylenediisocyanate-modified composition, in which the xylylenediisocyanate composition according to claim 1 is modified, wherein the xylylenediisocyanate-modified composition contains at least one of the functional groups of (a) to (i) below: (a) isocyanurate group, (b) allophanate group, (c) biuret group, (d) urethane group, (e) urea group, (f) iminooxadiazinedione group, (g) uretdione group, (h) uretonimine group, and (i) carbodiimide group. 5. Resin, wherein the resin is a reaction product of an isocyanate component containing the xylylenediisocyanate composition according to claim 1 , and at least one active hydrogen group-containing component selected from a group consisting of a polyol component, a polythiol component, and a polyamine component. 6. The resin according to claim 5 , wherein the resin is an optical material. 7. The resin according to claim 6 , wherein the resin is an optical lens. 8. Resin, wherein the resin is a reaction product of an isocyanate component containing the xylylenediisocyanate-modified composition according to claim 4 , and at least one active hydrogen group-containing component selected from a group consisting of a polyol component, a polythiol component, and a polyamine component. 9. The resin according to claim 8 , wherein the resin is an optical material. 10. The resin according to claim 9 , wherein the resin is an optical lens. 11. A two-component resin material comprising component A, which is an isocyanate component containing the xylylenediisocyanate composition according to claim 1 , and component B, which is an active hydrogen group-containing component. 12. The two-component resin material according to claim 11 , wherein the two-component resin material is a coating material. 13. A two-component resin material comprising component A, which is an isocyanate component containing the xylylenediisocyanate-modified composition according to claim 4 , and component B, which is an active hydrogen group-containing component. 14. The two-component resin material according to claim 13 , wherein the two-component resin material is a coating material. 15. The xylylenediisocyanate composition according to claim 1 , wherein less than 300 ppm of cyanobenzylisocyanate represented by Chemical Formula (3) below is contained: 16. The xylylenediisocyanate composition according to claim 1 , wherein the content of xylylenediisocyanate is 99 mass % or more.
