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.

Laminated optical component and touch sensor device

A method for producing an at least partially transparent optical component including a laminate including fabricating a precursor laminate by bonding a transparent substrate and a transparent film to each other with a transparent photocurable adhesive layer interposed therebetween; curing the transparent photocurable adhesive layer by applying light thereto to change the precursor laminate into the laminate thereby, such that a shear modulus G' of the transparent photocurable adhesive layer of the laminate measured under a condition of a temperature of 25&#xb0; C. and a frequency of 1 Hz reaches a value within a range of 3&#xd7;10Pa&#x2264;G&#x2032;&#x2264;3&#xd7;10Pa; and forming a flush and surface of the laminate by cutting the laminate in a thickness direction, such that the flush end surface includes respective cut surfaces of the transparent film, the transparent photocurable adhesive layer, and the transparent substrate.
