A sol-form application liquidis prepared by mixing together two solvents A and B and two film components C and D. The sol-form application liquidthus prepared is applied onto a glass substratethus forming a mixed layeron the glass substrateThe glass substratehaving the mixed layerformed thereon is left at room temperature, whereupon the solvent A evaporates and phase separation of the mixed layerinto an upper layerand a lower layeroccurs. The mixed layeris then heated, thus evaporating the solvent B in the lower layerand gelating the film component C in the upper layerand the film component D in the lower layerand hence forming an internal scattering layer
