Abstract
A photoluminescent material is formed by curing a blend of a transparent base material and a photoluminescent pigment component, wherein the viscosity of the transparent base material is 1 Pa·s(20° C.) or more and is added in an amount of 7 to 95 wt %. Luminescence performance is further improved by taking in consideration the relation between the internal structure of a molding and its luminescence performance, thereby achieving a luminescence of predetermined brightness for an extended period of time.
Claims15
A high performance photoluminescent material which comprises a cured composition of at least a transparent base material and a photoluminescent pigment component, wherein the transparent base material before curing has a viscosity of 2.0 Pa·s(20° C.) or more in the form of a liquid, viscous form, or melt and is present in a concentration of 7 to 95 wt %, and wherein the photoluminescent pigment component has a mean particle size of 150 to 2000 μm.
A method for producing a high performance photoluminescent material, which comprises:
- blending 7 to 95 wt % of a transparent base material based on the weight of the high performance photoluminescent material, having a viscosity of 2.0 Pa s (20° C.) or more, in the form of a liquid, viscous form or melt with a photoluminescent pigment component having a mean particle size of 150 to 2000 μm or a blend of a photoluminescent pigment component having a mean particle size of 150 to 2000 μm, another pigment component and a transparent aggregate, thereby obtaining a paste, mortar or viscous mass;
- and subjecting it to mold curing.
