Document Type and Number:
Japanese Patent JP2020138990
Kind Code:
A
Abstract:
To provide an active-energy-ray-polymerizable initiator that exhibits an excellent polymerization speed in response to an active energy ray, and can be sufficiently prevented from leaving from a polymerization product or moving to a contact object.SOLUTION: An active-energy-ray-polymerizable initiator having a structure represented by the general formula (1) in the figure is provided. In the formula, L1 represents -C(=O)-O- (binding to the L2 side), or -O-; L2 represents -O(CH2)p- (binding to the L1 side), -(OC2H4)n- (binding to the L1 side), or -(OC3H6)m- (binding to the L1 side), where p represents an integer from 2 to 16, n represents an integer from 2 to 12, and m represents 2 or 3; L3 represents a direct bond or -NH-; L4 represents -OC2H4- (binding to the L3 side), or -(OC2H4)2- (binding to the L3 side); and R represents -H or -CH3.SELECTED DRAWING: Figure 1
