Functional article, article for transport equipment, article for construction, and composition for coating

Provided is a functional article having a water absorption layer having wear resistance as well as a water absorption function involved in condensation prevention, humidity control, fouling prevention, fogging prevention, icing prevention, and the like; also provided are an article for transport equipment and an article for construction provided with the same. Further provided is a composition for coating making it possible to form a water-absorbent coating having a water absorption function involved in condensation prevention, humidity control, fouling prevention, fogging prevention, icing prevention, and the like, and also having wear resistance. This functional article having a substrate as well as a water absorption layer provided to at least one surface of the substrate is characterized in that the water absorption layer contains a porous inorganic particulate and also an inorganic oxide serving as a binder component. This composition for coating contains a porous inorganic particulate having a mean prim
