Composition, useful as optical substances e.g. in maritime domain, printing supports, home, fabric and textiles and reading screens, comprises substance for high photoluminescent powder in the form of micronized powder

摘要

Composition (A) of solutions, substances, materials or coverings, being optically transparent/translucent in one part and photoluminescent in other part and developed in solid, liquid or gaseous medium, comprises: a base substance (I) having high photoluminescent power, in micronized powder form having an average distribution of 1-50 mu and mass percentage of 6-80% of (A); and a matrix (II) being translucent/transparent or becomes translucent/transparent after application or implementation, having a good optical quality, i.e. chemically compatible with and intended to obtain (I). Independent claims are included for: (1) a juxtaposition of a layer comprising (A) with at least a layer of a base material containing doping products acting as catalysts, with complementary luminous effects, creating visual effects and providing a reinforcement or a modification of the photoluminescent effect of the juxtaposed layer; (2) excitation of non-photoluminescent element present in a composition or in a layer by natural light and/or other energy source, which transmits all or part of its energy to photoluminescent particles; (3) application of a composition or a juxtaposition of layers on parts of the object surface; and (4) application of a composition or a juxtaposition of layers on transparent/translucent supports forming supports that can be positioned for short time or permanently to the surface of an object for revealing its surface in darkness.
