ABSTRACT:
The luminescent material(s) optionally composed of more color components are suspended in the solution of active agent(s) and treated with 0.5 to 10% by weight of glass forming acid or a mixture thereof, preferably boric acid or phosphoric acid calculated on the weight of the luminescent material. Then a solution comprising 1 to 15% by weight of aliphatic amines calculated on the weight of the luminescent materials is added and the mixture thus obtained is homogenized.
