ABSTRACT:
Sheet materials are provided which are photoluminescent by virtue of their coating.
These sheet materials comprise a textile or other flexible sheet material substrate to which adheres a coating layer consisting of one or more synthetic resins admixed with a photoluminescent complex, the latter comprising (a) a phosphorescent metal sulphide such as zinc, calcium, cadmium or strontium sulphide and (b) a first substance which absorbs energy of short wavelength and emits it within the absorption spectrum of the said sulphide and with or without (c) a second substance which is fluorescent and which imparts to the said sheet materials a daytime coloration different from their nighttime coloration.
The sheet materials may be textile sheet materials useful for the production of garments, in particular safety garments and furnishing fabrics. Self-adhesive materials may also be produced.
