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. |
