Zusammenfassung:PURPOSE: To obtain high transmission of diffused light and favorable durability against running drops by a method wherein layer A, which is made of liquid composition containing alcohol-soluble type or water-dispersible type fluoropolymer and inorganic hydrophilic colloidal substance, is laminated onto the surface-treated surface of layer B, which is derived from the specified fluoroplastic film. CONSTITUTION: The agricultural fluoroplastic laminate is produced by laminating layer B onto the surface-treated surface of the layer B having adhesion improving surface-treated layer. The layer B consists of fluoroplastic film, the total light transmittance measured with a haze meter of which is 80% or more and the diffused light transmittance of which is 10% or more and which has adhesion improving surface-treated surface. Layer A is made of liquid composition containing alcohol-soluble type or water-dispersible type fluoroplastic polymer and inorganic hydrophilic matter. The layer A is produced by applying liquid composition containing fluoroplastic polymer and inorganic hydrophilic colloidal substance onto the surface-treated surface of the layer B, which is made of fluoroplastic film, and then drying.
