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.

A photoluminescent formulation comprising:
- (a) an effective amount of photoluminescent phosphorescent materials;
- (b) at least one liquid carrier medium;
- (c) at least one polymeric resin;
- and
- (d) at least one formulation stabilizing additive,
- wherein said photoluminescent phosphorescent materials are uniformly distributed within said formulation, wherein there are no additional materials that are absorptive colorant pigments, and further wherein said stabilizing additive is not in a solid particulate state in said liquid carrier medium.
A photoluminescent formulation comprising:
- (a) an effective amount of photoluminescent phosphorescent materials;
- (b) at least one liquid carrier medium;
- (c) at least one polymeric resin;
- and
- (d) at least one formulation stabilizing additive,
- wherein said photoluminescent phosphorescent materials are uniformly distributed within said formulation, wherein there are no additional materials that are absorptive colorant pigments, wherein said formulation stabilizing additive comprises a dispersing agent and a rheology modifier, and further wherein said stabilizing additive is not in a solid particulate state in said liquid carrier medium.
The photoluminescent formulation of any one of claims 3-16 and claim 77, which further comprises photoluminescent fluorescent materials.
A photoluminescent formulation comprising, by weight of the formulation:
- (a) from about 33% to about 40% of photoluminescent phosphorescent materials, wherein said photoluminescent phosphorescent materials are selected from the group consisting of H-13, H-14, green phosphor pigment, and blue phosphor pigment, and wherein said photoluminescent phosphorescent materials are uniformly distributed within said formulation;
- (b) a liquid carrier medium comprising EGMME and MIBK, wherein EGMME is present in amount of about 28% to about 40%;
- (c) an acrylic polymeric resin, wherein said acrylic polymeric resin is selected from the group consisting of NeoCryl B-818, NeoCryl B-735, NeoCryl B-813, and combinations thereof, and wherein the ratio of photoluminescent phosphorescent material to acrylic polymeric resin is from 1 to 2;
- (d) a stabilizing additive, wherein said stabilizing additive comprises a dispersing agent that is DISPERBYK-180, DISPERBYK-181, DISPERBYK-108, or Tego Disperse 710, wherein said stabilizing additive is present in amount of about 1% to about 3%;
- a rheology modifier that is BYK-410 or BYK-411, wherein said rheology modifier is present in amount of about 1% to about 2%;
- a wetting agent that is Tego Wet 270 or Tego Wet 500 present in the amount of about 0.5% to about 2.5%;
- and a deaerator/defoamer that is Tego Airex 900, wherein said dearator/defoamer is present in amount of about 1% to about 3%.
