Title:
ACTIVE ENERGY RAY-CURABLE COMPOSITION AND METHOD FOR PRODUCING MATTE COATING FILM
Document Type and Number:
WIPO Patent Application WO/2024/085048
Kind Code:
A1
Abstract:
Provided are: an active energy ray-curable composition which achieves a viscosity suitable for coating agents, low glossiness for achieving a matte effect, contamination resistance and scratch resistance at the same time; and a method for producing a matte coating film. This active energy ray-curable composition contains an active energy ray-curable compound, a photopolymerization initiator and a matting agent. (1) The composition contains ethylene oxide-modified 1,6-hexane diol diacrylate in an amount of 10% by mass to 50% by mass relative to the total mass of the compound, and ethylene oxide-modified trimethylolpropane triacrylate in an amount of 10% by mass to 50% by mass relative to the total mass of the compound. (2) The matting agent has a particle diameter of 1 μm to 10 μm, and is contained in an amount of 5% by mass to 20% by mass relative to the total mass of the compound. (3) The composition contains a monofunctional monomer in an amount of 1% by mass to 30% by mass.
