Abstract

PURPOSE:To prevent the already deposited film from dissolving out by mixing into suspension for the second layer and the subsequent, a diluent, which does not dissolve a binder in the suspension applied on the first layer but miscible mutually with the solvent in the suspension. CONSTITUTION:A fluorescent lamp is manufactured by making at least two layers including a phosphor 1 layer on the inside wall of a glass valve. In the suspension which is to be applied, all amount of powder is dispersed in a solvent containing a binder. Especially the suspension to be applied onto the second and subsequent layers is mixed with an additional diluent which hardly dissolves the binder in the suspension which has been preliminarily applied onto the first layer, but well miscible mutually with the solvent.
