ABSTRACT:
A photosensitive composition is disclosed, which is capable of offering a visual, calibrated reaction to the presence of ultraviolet radiation. The composition comprises a complex of a leuco dye and animal-derived serum albumin. The preparation of this complex has been found to stabilize the leuco dyes, to avoid fading after the presentation of a color reaction upon exposure. Also, the leuco dye-serum albumin albumin complex is capable of exacting calibration, so that scientifically significant quantitative measurements of ultraviolet light exposure can be made. Moreover, the present composition eliminates the need for the addition to the leuco dye of various activator compounds, that are chemically unstable, e.g. volatile, or present potential exposure to toxicity, in the instance where personal applications for the photosensitive composition are contemplated.
The present invention includes a method of preparing the photosensitive composition, including the preparation of an ultraviolet light indicator.
