PURPOSE: An acrylate compound is provided do have low refractivity, excellent transparency after curing, to have low yellowing even in case of being exposed to light for long time, and to have excellent moldability, adhesion, optical properties. CONSTITUTION: An acrylate compound is in chemical formula 1. A manufacturing method of the acrylate compound comprises esterification of a compound in chemical formula 1 and a compound in chemical formula 2 under the presence of a catalyst. In chemical formula 1, R1 and R2 is independently hydrogen, C1-7 alkyl or C5-10 aryl, R3 is hydrogen or methyl, R4 is C1-7 alkyl, and n is an integer from 0-10. The viscosity of the acrylate compound at 25°C is 40-170 cps, and the refractivity is 1.59-1.65. |
