Abstract
Chromophoric-moiety-containing, polymeric materials, containing at least one fluoroaliphatic radical, which are useful as dyes or colorants for fluorine-containing liquids, as coatings or components of coatings which are colored, light-absorbing, or fluorescing and characteristic properties of fluorocarbon polymers, e.g. chemical inertness and hydrophobicity; and a method of detecting leaks in normally sealed devices, e.g. electronic devices, using a coating which includes the polymeric material, and a bath of a fluorine-containing liquid in which the coating is soluble.
