Abstract
To provide an agricultural film which has high transparency and which has a coating film formed with excellent abrasion resistance (adhesion), hydrophilicity (anti-fogging, wettability and anti-fouling) and hydrophilic durability. An agricultural filmcomprising a base material filmand a porous hydrophilic coating filmformed on the base material film. The hydrophilic coating filmcontains boehmite particles, silica particles and a binder, wherein (a) the atomic ratio of Al to Si (Al/Si) is from 0.2 to 5.0, (b) the average particle diameter of the silica particles is from 5 to 50 nm, and (c) the crystallite diameter of the boehmite particles, as calculated from the diffraction peak of the (120) plane is from 20 to 50 nm. The hydrophilic coating filmis formed by applying a composition comprising boehmite particles, silica particles, a binder and water, on a surface of a base material film, followed by drying.
