Abstract
Disclosed are photoluminescent formulations, comprising an effective amount of photoluminescent phosphorescent materials, which exhibit high luminous intensity and persistence. Also disclosed are photoluminescent objects formed by applying at least one photoluminescent layer, formed from photoluminescent formulations, to preformed articles. Further disclosed are methods for creating photoluminescent objects.
Claims15
A photoluminescent formulation comprising:
- an effective amount of a phosphorescent material;
- a liquid carrier medium;
- a polymeric resin that is at least one of acrylates, polyvinyl chlorides, polyurethanes, polycarbonates, or polyesters;
- and
- a formulation stabilizing additive that comprises a rheology modifier and a wetting agent, said formulation stabilizing additive being dissolved in said liquid carrier medium;
- wherein the formulation has a Film Transmissivity (FT) of at least about 95%, without the presence of additional absorptive coloring pigments;
- and wherein the phosphorescent material is substantially uniformly distributed within the formulation.

A method for creating a photoluminescent object, the method comprising:
- obtaining a preformed article;
- and applying to the preformed article a photoluminescent formulation to form a photoluminescent layer;
- wherein the photoluminescent formulation comprises an effective amount of a phosphorescent material, a liquid carrier medium, a polymeric resin that is at least one of acrylates, polyvinyl chlorides, polyurethanes, polycarbonates, or polyesters, and a formulation stabilizing additive that comprises a rheology modifier and a wetting agent, said formulation stabilizing additive being substantially dissolved in said liquid carrier medium;
- wherein the formulation has a Film Transmissivity (FT) of at least about 95%, without the presence of additional absorptive coloring pigments;
- and wherein the phosphorescent material is substantially uniformly distributed within the formulation.

A photoluminescent formulation comprising:
- an effective amount of a phosphorescent material;
- a liquid carrier medium;
- a polymeric resin that is at least one of acrylates, polyvinyl chlorides, polyurethanes, polycarbonates, or polyesters;
- and
- a formulation stabilizing additive that comprises a rheology modifier, a deaerator/defoamer, and a wetting agent, said formulation stabilizing additive being dissolved in said liquid carrier medium;
- wherein the formulation has a Film Transmissivity (FT) of at least 90.0%, without the presence of additional absorptive coloring pigments;
- wherein the phosphorescent material is substantially uniformly distributed within the formulation;
- and
- wherein the ingredients of the formulation are selected to prevent degradation of luminous intensity of the formulation.
