Zusammenfassung:The present invention relates to a master mixture comprising:from 40 to 95% by weight of a photoluminescent pigment, said pigment having a particle size limited by sifting at 30 μm;5 to 60% by weight of a polymer in the form of an elastomer or an elastomer precursor chosen from fluorinated polymers from the FKM family, the polyurethane (TPU) family, Ethylene vinyl acetate (EVA) copolymers, silicones, ethylene propylene rubbers (EPR) and the thermoplastic derivatives (TPO) thereof and acrylic elastomers.
