Laminate and method for manufacturing laminate

A laminate comprising:

• a dielectric film;
• a first metal pattern composed of a plurality of first metal structures, which is disposed on one surface side of the dielectric film;
• a first organic film in which a moisture permeability under an environment of a temperature of 40° C. and a relative humidity of 90% is 3000 g/(m2·24 hr) or less, which is disposed on the first metal pattern;
• a second metal pattern composed of a plurality of second metal structures, which is disposed on the other surface side of the dielectric film;
• and
• a second organic film in which a moisture permeability under the environment of a temperature of 40° C. and a relative humidity of 90% is 3000 g/(m2·24 hr) or less, which is disposed on the second metal pattern,
• wherein the first organic film and the second organic film are formed of a curable composition, and the curable composition contains a blocked isocyanate having a structure in which the isocyanate group is protected with a blocking agent, and wherein the curable composition further contains a binder polymer having a constitutional unit represented by Formula(S) and a constitutional unit represented by Formula (Cy),
• wherein, in Formula (Cy), RM represents a hydrogen atom or a methyl group, and RCy represents a monovalent group having an aliphatic hydrocarbon ring structure, and
• wherein the first metal pattern and the second metal pattern form a resonator with respect to electromagnetic waves in a terahertz band.

A method for manufacturing a laminate, comprising:

• a step 1A of bonding a film with a metal pattern, that includes a dielectric film and a metal pattern serving as a resonator with respect to electromagnetic waves in a terahertz band, which is disposed on at least one surface side of the dielectric film, to a transfer film including a temporary support and a curable composition layer to form a precursor film including the dielectric film, the metal pattern, the curable composition layer, and the temporary support in this order, wherein the curable composition layer contains a blocked isocyanate having a structure in which the isocyanate group is protected with a blocking agent, and wherein the curable composition layer further contains a binder polymer having a constitutional unit represented by Formula(S) and a constitutional unit represented by Formula (Cy),
• wherein, in Formula (Cy), RM represents a hydrogen atom or a methyl group, and RCy represents a monovalent group having an aliphatic hydrocarbon ring structure;
• and
• a step 2A of subjecting the curable composition layer to a curing treatment to obtain an organic film in which a moisture permeability under an environment of a temperature of 40° C. and a relative humidity of 90% is 3000 g/(m2·24 hr) or less,
• wherein a step of peeling off the temporary support is further provided between the step 1A and the step 2A or after the step 2A.

A method for manufacturing a laminate, comprising:

• a step 1B of bonding a film with a metal pattern, that includes a dielectric film, a first metal pattern composed of a plurality of first metal structures, which is disposed on one surface side of the dielectric film, and a second metal pattern composed of a plurality of second metal structures, which is disposed on the other surface side of the dielectric film, where the first metal pattern and the second metal pattern form a resonator with respect to electromagnetic waves in a terahertz band, to a transfer film including a temporary support and a curable composition layer to form a precursor film including the temporary support, the curable composition layer, the first metal pattern, the dielectric film, the second metal pattern, the curable composition layer, and the temporary support in this order, wherein the curable composition layer contains a blocked isocyanate having a structure in which the isocyanate group is protected with a blocking agent, and wherein the curable composition layer further contains a binder polymer having a constitutional unit represented by Formula(S) and a constitutional unit represented by Formula (Cy),
• wherein, in Formula (Cy), RM represents a hydrogen atom or a methyl group, and RCy represents a monovalent group having an aliphatic hydrocarbon ring structure;
• and
• a step 2B of subjecting the curable composition layers to a curing treatment to obtain organic films in which a moisture permeability under an environment of a temperature of 40° C. and a relative humidity of 90% is 3000 g/(m2·24 hr) or less,
• wherein a step 3B of peeling off the temporary supports is further provided between the step 1B and the step 2B or after the step 2B.
