Abstract

The present invention addresses the problem of providing an anti-fogging composition having excellent transparency and long-lasting anti-fogging properties and anti-fogging performance, whereby an anti-fogging layer formed by applying the anti-fogging composition exhibits excellent scratch resistance and resistance to flexural whitening. The present invention provides an anti-fogging composition containing colloidal silica, a binder resin, a film-forming auxiliary, and a surfactant, the anti-fogging composition being characterized in that (1) the mass ratio (Ma/Mb) of the solid content mass (Ma) of the colloidal silica and the solid content mass (Mb) of the binder resin is 0.5-5.0, (2) the film-forming auxiliary includes carbon atoms and has a boiling point of 100°C or higher, and (3) the mass ratio (Ma + Mb)/(Mc) of the sum of the solid content mass (Ma) of the colloidal silica and the solid content mass (Mb) of the binder resin (Ma + Mb) and with respect to the mass (Mc) the film-forming auxiliary is 1.0-16.0.

Abstract

The present invention provides: a vegetation sheet whereby it becomes possible to prevent the drop of an content, e.g., seeds, from the vegetation sheet and which can have blocking resistance even when stored in the form of a roll for a long period; and a water-soluble resin film which is suitable for the production of the vegetation sheet. The present invention specifically provides a water-soluble multi-layer film composed of two layers, i.e., a layer (1) and a layer (2), said multi-layer film being characterized in that the layer (1) has a time required for complete dissolution thereof (a water dissolution time) of 90 seconds or longer and the layer (2) has a water dissolution time as mentioned above of shorter than 90 seconds as measured by subjecting the film to a water solubility test (A).
