Optical laminate, transfer laminate, and method for manufacturing optical laminate

An optical laminate comprising:

• an adherend;
• a bonding layer formed on at least part of a surface of the adherend;
• and
• an optical body bonded to the adherend with the bonding layer, wherein
• a micro concave-convex structure in which concavities and convexities are arranged at an average cycle less than or equal to a visible light wavelength is formed in at least one surface of the optical body, and the bonding layer is formed on the other surface of the optical body, and
• a 90° peeling force between the optical body and the bonding layer is more than or equal to 13 N/25 mm.

A transfer laminate comprising:

• an optical body, in at least one surface of which a micro concave-convex structure in which concavities and convexities are arranged at an average cycle less than or equal to a visible light wavelength is formed;
• a transfer body having an inverted concave-convex structure fitted in the micro concave-convex structure of the optical body;
• and
• a covering body that covers one of surfaces of the optical body that is located on a side where the transfer body is not provided, wherein
• a 90° peeling force between the optical body and the covering body is smaller than a 90° peeling force between the optical body and the transfer body including tearing of the optical body.

A method for manufacturing an optical laminate, comprising:

• producing a transfer laminate having an optical body, in at least one surface of which a micro concave-convex structure in which concavities and convexities are arranged at an average cycle less than or equal to a visible light wavelength is formed, and a transfer body having an inverted concave-convex structure fitted in the micro concave-convex structure of the optical body;
• forming a bonding layer yet to be cured on at least part of a surface of an adherend;
• pressing the transfer laminate against the adherend such that an exposed surface of the optical body comes into contact with the bonding layer yet to be cured;
• curing the bonding layer yet to be cured;
• and
• peeling the optical body from the transfer body, wherein
• an initial 90° peeling force when peeling the optical body from the transfer body is less than or equal to 70% of a 90° peeling force between the optical body and the bonding layer.
