| 摘要 |
<p>This (meth)acrylate-based composition comprising a (meth)acrylate compound (A) that has an adamantyl group represented by general formula (A-1) and a (meth)acrylate compound (B) that has a specific structure in a single molecule has excellent workability because the composition has high viscosity while maintaining good heat resistance, shape stability, and optical performance, such as refractive index and transparency. (In formula (A-1): each R1 independently represents a hydrogen atom or a methyl group; each X independently represents a single bond, a C1-4 alkylene group, or a C1-4 oxyalkylene group; U represents a C1-4 alkyl group, a halogen group, a hydroxyl group, or =O formed by linking two Us; k represents an integer from 0 to 15; and m represents an integer from 1 to 4.)</p> |
