Title:
活性エネルギー線硬化型組成物、硬化物、および硬化物の製造方法
Document Type and Number:
Japanese Patent JP7434745
Kind Code:
B2
Abstract:
To provide an active energy ray-curable composition that achieves both of high tensile strength and high impact resistance and is used to produce a three-dimensional molding.SOLUTION: An active energy ray-curable composition contains (A) a radical-polymerizable monofunctional monomer, (B) a soft crosslinker (polyfunctional monomer), (C) a hard radical-polymerizable oligomer, and (D) a polymerization initiator. A degree of crosslinking expressed by [the total number of polymerizable functional groups in the composition/the total mol of all the polymerizable compounds] is 1.13-1.20.SELECTED DRAWING: None
