Abstract
(EN)
Disclosed is an agricultural film that is highly transparent and on which a coating film is formed with superior mar-resistance (adhesion), hydrophilicity (anti-fogging, anti-drop, and anti-fouling properties), and hydrophilic durability. An agricultural film (10) comprises a base material film (12) and a porous, hydrophilic coating film (14), which is formed on the base material film (12). The aforementioned hydrophilic coating film (14) contains boehmite particles, silica particles, and a binder, wherein (a) the atomic ratio of Al and Si (Al/Si) is 0.2‑5.0, (b) the average grain size of the silica particles is 5‑50 nm, and (c) the crystallite diameter of the boehmite particles, calculated from the diffraction peak of the (120) plane, is 20‑50 nm. The aforementioned hydrophilic coating film (14) is formed by applying a composition containing boehmite particles, silica particles, a binder, and water to the surface of the base material film, and then drying the composition.

L'invention concerne un film agricole qui est très transparent et sur lequel est formé un film de revêtement doté d'une résistance à l'abrasion (adhésion), une hydrophilie (propriétés anticondensation, antigoutte et antisalissure) et une durabilité hydrophile supérieures. L'invention concerne un film agricole (10) comprenant un film de matériau de base (12) et un film de revêtement hydrophile poreux (14), qui est formé sur le film de matériau de base (12). Le film de revêtement hydrophile (14) mentionné ci-dessus contient des particules de boehmite, des particules de silice et un liant, (a) le rapport atomique de Al à Si (Al/Si) étant de 0,2-5,0, (b) la taille moyenne de grain des particules de silice étant de 5-50 nm, et (c) le diamètre de cristallite des particules de boehmite, calculé d'après le pic de diffraction du plan (120), étant de 20-50 nm. Le film de revêtement hydrophile (14) mentionné ci-dessus est formé en appliquant une composition contenant des particules de boehmite, des particules de silice, un liant, et de l'eau sur la surface du film de matériau de base, puis en séchant la composition.
