PURPOSE:To preserve superior clouding preventing effect for a long time by providing moisture absorbing resin layer on the surface of at least one side of transparent plastic or glass, and providing further a layer of water-wettable resin on the surface of the moisture absorbing resin layer(s). CONSTITUTION:Moisture absorbing resin layer(s) is(are) formed on the surface of at least one side of transparent plastic base material or on a glass base material, and a layer of water-wettable resin is formed on the moisture absorbing resin layer(s). Suitable moisture absorbing resin layer consists of a compsn. consisting primarily of a hydrophilic polymer or oligomer such as ethylene oxide adduct of polyhydric alcohol, polyethylene glycol of polymer or copolymer such as polyvinyl alcohol, hydrophilic acrylic monomer, contg. a crosslinking agent for forming a three dimensional network, reaction catalyst, solvent, etc. Suitable water-wettable resin layer is a layer of resin having easily wettable characteristic by water, but it is not always necessary to have a small angle of contact in advancing movement when a water drop is allowed to contact with the resin; a resin having a very small angle of contact in retreating movement without repelling water when contacting with water drop, but forming water film on its surface, may be also useful.
