Title:

An active energy-rays hardenability constituent and a hardened material

Document Type and Number:

Japanese Patent JP6179150

Kind Code:

B2

Abstract:

PROBLEM TO BE SOLVED: To provide an active energy ray-curable composition which can be favorably adhered to an acrylic substrate.SOLUTION: The provided active energy ray-curable composition includes active energy ray-polymerizable compounds and a photopolymerization initiator, whereas at least 85 mol% of a (meth)acryloyl group-containing polyfunctional (meth)acrylate having an acrylic equivalent of 78-145 is included as one active energy ray-polymerizable compound with respect to all active energy ray-polymerizable compounds, whereas the ester group concentration with respect to the entirety of the active energy ray-polymerizable compounds is at least 7.4 mmol/g; a cured product of the same is also provided.
