MULTIFUNCTIONAL (METH)ACRYLATE HAVING FLUORENE SKELETON AND CURABLE COMPOSITION CONTAINING SAME

摘要

Provided is a fluorene skeleton-containing multifunctional (meth)acrylate which has a good balance between excellent scratch resistance and high refractive index. In formula (1), the average of m1 + m2 is regulated to 8.5-17. (In the formula, each of R1a and R1b represents a non-radically polymerizable substituent; each of R2a and R2b represents an alkylene group; each of R3a and R3b represents a hydrogen atom or a methyl group; each of R4a and R4b represents a non-radically polymerizable substituent; each of k1 and k2 represents an integer of 0-4; each of m1 and m2 represents an integer of 0 or more; each of n1 and n2 represents an integer of 1-4; and each of p1 and p2 represents an integer of 0-4. In this connection, n1 + p1 = 5 and n2 + p2 = 5.)
