Laminate

A laminate comprising:

• an antireflection film and a protection film bonded onto the antireflection film,
• wherein a surface of the antireflection film comprises a plurality of protrusions wherein a width between the tops of adjacent protrusions is equal to or less than a wavelength of visible light;
• the protection film comprises a supporting film and an adhesive layer in contact with the antireflection film;
• the adhesive layer is constituted with an adhesive agent that has a gel fraction of 95% or more and is prepared by cross-linking with an epoxy cross-linking agent a copolymer obtained by polymerizing monomer components comprising as essential components a (meth)acrylic acid alkyl ester with the alkyl group having 4 or less carbon atoms, and a carboxyl group-containing monomer;
• the monomer components including at least one of methyl (meth)acrylate and butyl (meth)acrylate as the (meth)acrylic acid alkyl ester and (meth)acrylic acid as the carboxyl group-containing monomer;
• the weight average molecular weight of the copolymer is 1000000 or more and 2000000 or less;
• the copolymer comprises the (meth)acrylic acid alkyl ester with the alkyl group having 4 or less carbon atoms in the largest weight proportion among the monomer components,
• the acid number of the copolymer is 16 mg KOH/g or more and 46 mg KOH/g or less;
• and
• the mixing amount of the epoxy cross-linking agent in relation to 100 parts by weight of the copolymer is 1.5 parts by weight or more and 5 parts by weight or less.
