Abstract
An active-energy-ray-polymerizable initiator having a structure represented by the following general formula (1) is provided. In general formula (1), L1 represents —C(═O)—O— (binding to L2 side) or —O—, L2 represents —O(CH2)p-(binding to L1 side), —(OC2H4)n-(binding to L1 side), or —(OC3H6)m-(binding to L1 side), where p represents an integer of 2 to 16, n represents an integer of 2 to 12, and m represents 2 or 3, L3 represents a direct binding or —NH—, L4 represents —OC2H4-(binding to L3 side) or —(OC2H4)2-(binding to L3 side), and R represents —H or —CH3.
