Composition for coating plastic substrate, coating film formed therefrom, and formed body

摘要

The present invention relates to a composition for coating a plastic substrate, a coating film formed therefrom and a molded body. The composition can form a coating film that exhibits favorable adhesion to plastic substrates, as well as excellent abrasion resistance and weather resistance. The coating film-forming components of the composition include silica particles having (meth)acryloyl groups, a hexafunctional or higher aliphatic urethane(meth)acrylate, and an active energy beam-curable compound having an alicyclic structure, wherein the amount of the silica particles is within a range from 1.0 to 40 mass %, relative to 100 mass % of the coating film-forming components.
