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.”

Claims

1-77. -77. (canceled)

78. A layer resulting from a formulation, said formulation comprising:

at least one liquid carrier medium;

at least one fully polymer resin; and

an effective amount of photoluminescent fluorescent materials;

said photoluminescent fluorescent materials being emission color altering fluorescent materials, wherein said emission color altering fluorescent materials alter perceived primary color of electromagnetic radiation externally supplied to said layer.

79. The layer of claim 78 wherein said emission color-altering fluorescent materials are selected from the group consisting of Xanthene type fluorescent dyes including rhodamine and fluorescene dyes, coumarin dyes, phenoxazone dyes including nile red, nile blue, cresyl violet, phoenoxazoles styryl type dyes, Carbostyryl type dyes, Stilbene type dyes, and combinations thereof.

80. The layer of claim 78 wherein said photoluminescent fluorescent materials are in solution in said at least one liquid carrier medium.

81. The layer of claim 78 wherein said at least one polymeric resin is selected from the group consisting of acrylates, polyvinyl chlorides, polyurethanes, polycarbonates, and polyesters, and combinations thereof.

82. A method for altering perceived primary color of electromagnetic radiation, the method comprising the steps of:

providing a layer resulting from a formulation, said formulation comprising;

at least one liquid carrier medium;

at least one fully polymer resin; and

an effective amount of photoluminescent fluorescent materials;

said photoluminescent fluorescent materials being emission color altering fluorescent materials, wherein said emission color altering fluorescent materials alter the perceived primary color of electromagnetic radiation externally supplied to said layer.

83. The method of claim 82 wherein said emission color-altering fluorescent materials are selected from the group consisting of Xanthene type fluorescent dyes including rhodamine and fluorescene dyes, coumarin dyes, phenoxazone dyes including nile red, nile blue, cresyl violet, phoenoxazoles styryl type dyes, Carbostyryl type dyes, Stilbene type dyes, and combinations thereof.

84. The method of claim 82 wherein said photoluminescent fluorescent materials are in solution in said at least one liquid carrier medium.

85. The method of claim 82 wherein said at least one polymeric resin is selected from the group consisting of acrylates, polyvinyl chlorides, polyurethanes, polycarbonates, and polyesters, and combinations thereof.
