<p>The coloured transparent lacquer is applied on a metal foil with reflecting surface. The reflected light is pref. separated by special surface treatment of metal foil into the constituent spectral colours. The process used in coating is relatively simple and inexpensive. The metal foil surface is treated before applying the transparent lacquer with a thinning agent, preferably with cellulose paint thinner. This solvent can be mixed additionally into the lacquer before its application. The lacquer is applied directly on the metal foil without previously applying a carrying lacquer layer by spraying.</p> |
