Abstract
A laminated optical component, including a transparent substrate, a transparent adhesive layer superposed on the transparent substrate, the transparent adhesive layer including both a first type of crosslinking and a second type of crosslinking of (meth)acrylic polymer, the first type of crosslinking being formed of a first reaction site selected from a first group consisting of: a hydroxyl group, a carboxyl group, and an amino group, and a second reaction site selected from a second group consisting of: an isocyanate group, an epoxy group, and a metal atom, and the second type of crosslinking being formed by addition polymerization of unsaturated double bond, and a transparent film superposed on the transparent adhesive layer, wherein the transparent substrate, the transparent adhesive layer, and the transparent film form a flush-ended laminate having an end surface.
