Applications of photoerasable colorant composition include photoerasable price markings for pricing goods, documents such as gaming tickets for securely communicating concealed information, photoerasable paint for temporary markings on terrain and structures such as signs, roadways, trees, and build
Applications of photoerasable colorant composition include photoerasable price markings for pricing goods, documents such as gaming tickets for securely communicating concealed information, photoerasable paint for temporary markings on terrain and structures such as signs, roadways, trees, and buildings, marking instruments such as pens, and wick or felt markers, ultraviolet light exposure indicators, and dry printing. The photoerasable or mutable colorant composition comprises a mutable colorant and an ultraviolet radiation transorber which, upon irradiation with ultraviolet radiation, interacts with the colorant to irreversibly mutate the colorant and thereby render the colorant substantially colorless. The mutable colorant composition may also include a molecular includant.
[ What is claimed is:] [1.] An ultraviolet light exposure indicator comprising:a substrate having a surface; anda mutable colorant composition located on first and second areas of said surface, said composition comprising:a mutable colorant;a molecular includant; andan ultraviolet radiation transorb
[ What is claimed is:] [1.] An ultraviolet light exposure indicator comprising:a substrate having a surface; anda mutable colorant composition located on first and second areas of said surface, said composition comprising:a mutable colorant;a molecular includant; andan ultraviolet radiation transorber covalently coupled to the molecular includant and adapted, upon interaction with ultraviolet radiation, to irreversibly mutate the colorant; andwherein the amount of mutable colorant in said composition in said second area is different from the amount of mutable colorant in said first area so that, when the composition is exposed to ultraviolet radiation, the composition provides an indication of the dosage of ultraviolet radiation to which the composition was exposed.
