Laminate, card, method of manufacturing card, method of producing card, card information recording sheet and card including the same

A laminate, comprising:

• in a thickness direction of the laminate,
• a transfer foil in which at least a patch substrate, a relief forming layer, a first reflective layer, a second reflective layer, and an adhesive layer are sequentially laminated;
• a protective sheet that is provided on a first side of the transfer foil in the thickness direction;
• and
• an information recording sheet that is provided on a second side of the transfer foil facing away from the first side in the thickness direction, wherein
• at least one of the first reflective layer and the second reflective layer is composed of a light transmissive material having a higher refractive index than the relief forming layer and the adhesive layer,
• the relief forming layer includes a relief structure having a concavo-convex shape composed of concavities and convexities on at least part of a first surface of the relief forming layer in contact with the first reflective layer,
• a second surface of the first reflective layer in contact with the first surface has a shape corresponding to the concavo-convex shape of the relief structure,
• the first reflective layer has a surface shape corresponding to a surface shape of the second reflective layer at an interface at which the first reflective layer is in contact with the second reflective layer,
• the transfer foil has a plurality of regions that are arranged in a predetermined pattern as viewed in the thickness direction and include a first region and a second region,
• the first region includes the first reflective layer and the second reflective layer,
• the second region includes only the first reflective layer,
• an interfacial adhesion strength between the first reflective layer and the adhesive layer is different from an interfacial adhesion strength between the second reflective layer and the adhesive layer, and
• the first region or the second region, whichever has a relatively high interfacial adhesion strength at an interface with the adhesive layer, is island regions scattered in the other region, and the first region or the second region, whichever has a relatively low interfacial adhesion strength at an interface with the adhesive layer, is a sea region that surrounds the region having a relatively high interfacial adhesion strength at the interface with the adhesive layer.
