Daylight Fluorescent Pigment

Hiding patterns with daylight fluorescent inks

We propose a method for hiding patterns within printed images by making use of classical and of two daylight fluorescent magenta and yellow inks. Under the D65 illuminant we establish in the CIELAB space the gamut of a classical cmyk printer and the gamut of the same printer using a combination of classical inks with daylight fluorescent inks. These gamuts show that a significant part of the cl...

Iron-induced accumulation of lipofuscin-like fluorescent pigment in the retinal pigment epithelium.

PURPOSE One of the most prominent changes that occurs in the retinal pigment epithelium during senescence is the progressive accumulation of the autofluorescent pigment lipofuscin. Experiments were conducted to evaluate the role of nonenzymatic oxidation of photoreceptor outer segments in retinal pigment epithelium lipofuscin formation. METHODS Albino Fischer rats were given intravitreal inje...

Fluorescent pigment accumulation in retinal pigment epithelium of antioxidant-deficient rats.

A yellow autofluorescent pigment, generally thought to be indicative of membrane autoxidation, was found to accumulate in the retinal pigment epithelium (RPE) of rats maintained for 32 weeks on diets producing physiological antioxidant deficiency. The largest build-up of fluorescent pigment occurred in rats fed a diet high in polyunsaturated fatty acids (PUFAs) and deficient in alpha-tocopherol...
