Coating composition, coating film, laminate, and process for manufacturing the laminate

A method for manufacturing a laminate comprising a substrate and coating film in contact with at least one surface of the substrate, the method comprising:

• applying a coating composition to at least one surface of a substrate to from a coating film, and
• subjecting the coating film at least one of a thermal treatment at 70° C. or more and a pressurization treatment at 0.1 kPa or more,
• wherein the coating composition comprises
• a component (A):
• comprises metal oxide particle having a number average particle size of 1 nm to 400 nm, and
• a component (B):
• comprises a polymer particle,
• wherein a content of an aqueous-phase component in the component (B), represented by the following expression (I), is 20 mass % or less:
• the content of the aqueous-phase component (%)=(dry mass of a filtrate obtained by filtering the component (B) at a molecular cutoff of 50,000)×(100−total mass of solid content)/(mass of the filtrate−dry mass of the filtrate)×100/the total mass of solid content (I).
