Abstract
Novel UV absorbers of benzotriazine type having a plurality of (meth)acryloxy groups have a UV absorbing capacity and a high solubility in multifunctional (meth)acrylate. By combining the (meth)acrylic functional UV absorber with various binder precursors such as photo-curable multifunctional (meth)acrylate, there are obtained coating compositions having improved crosslinking density, UV absorbing capacity, anti-bleeding property, and shelf stability.
