<p>A liquefied colour phosphorescent material consisting of a mixture which comprises a stock solution; a colourant; a colour-emitting phosphorescent fine pigment particle having an average particle diameter of 7 mu m or less; and an additive for stably dispersing pigments containing a cellulose-based synthetic resin, silica-based powder, cyclohexanone, isophorone and mineral spirit. The pigment particles of colourant and the colour-emitting phosphorescent fine pigment particle are enabled to be always maintained in a substantially uniform dispersion state in the stock solution, thereby making it possible to attain a desired emitting colour and to coat the phosphorescent material without necessitating the undercoating using a colour paint.</p> |
