Abstract: A visualization kit includes (i) a cyanoacrylate and (ii) a fluorescent agent containing at least one tetrazine of formula 1: wherein X and Y represent independently a nonionic, electron-withdrawing group selected from halogens, azide, cyano and O-A-R, in which A represents a single bond or a C1-C4 alkyldiyl and R is alkyl, alkenyl, alkynyl, cycloalkyl or epoxyalkyl, or an aziridine group, which is optionally substituted by alkyl or aryl. A method of cofugation and a method of visualizing traces on a substrate utilizing these components are also presented.

Abstract: The present invention relates to a visualization kit including (A) a cyanoacrylate and (B) a fluorescent agent having a molecular weight of less than 400 g·mol?1, a sublimation temperature of less than 200° C., and an extinction coefficient of less than 2950 L·mol?1·cm?1; to a method including the cofumigation of a cyanoacrylate (A) and a fluorescent agent (B); and to a method for visualizing traces on a substrate, employing the method of cofumigation.
