| 摘要 |
The present invention relates to (meth)acrylic compounds having a high refractive index, a preparation method therefor, an optical sheet comprising the same, and an optical display device comprising the same. The (meth)acrylic compounds of the present invention each independently comprise a thiophenol group, a thiobenzothiazole group (2-thiobenzothiazole group), a thiadiazole dithiol group (1,3,4-thiadiazole-2,5-dithiol group), a Z-substituted mercaptothiazole group (S-5-mercapto-1,3,4-thiadiazol-2-yl group), and a 1 to 5 Z-substituted phenol group, wherein Z is independently -OH, -NO2, -NH2, an electron donating group (EDG) or an electron withdrawing group( EWG), respectively, and * is a binding site; 1 or 2 (meth)acrylic group(s); and phosphorus (meth)acrylic 1,3,5-triazine compounds. |
