METHOD FOR THE PRODUCTION OF LONG-ENDURING LUMINESCENT SAFETY MARKINGS, SAFETY SIGNS AND THE LIKE

摘要

The invention relates to a method for the production of long-enduring luminescent safety markings, safety signs, safety guidance systems, safety guidance stripes and the like with extremely high luminance, especially for use outdoors, wherein at least one layer of at least one type of long-enduring luminescent pigment (long-enduring luminescent layer) is applied on a support coated preferably with a white reflecting layer using a silk screening process and said layer is sealed with at least one layer of protecting varnish. The invention is characterized in that a baking enamel is used both as binding agent and as protective varnish and in that the at least one long-enduring luminescent layer is initially hardened with a predetermined temperature-time profile and the protective varnish layer is subsequently hardened with another predetermined temperature-time profile.
