Fluorescent yellow dyes of the aminonaphthalimide type which have the following structures: ##STR1## In the formula above alk (alkali metal) may be substituted for Li.sup.+ and thus alk may be Li.sup.+, Na.sup.+, or K.sup.+, but the preferable structure is Li.sup.+. These dyes have shown superior activity in intracellular use in vivo in tissues such as turtle retina and wholemount tissue observation.
