<p>The present invention provides an amino-1,8-naphthalimide compound having substituent groups at the imide position and a position distal to the imide position. The substituent groups are linked to a hydrocarbon directly linked at the imide position and the distal position. The substituent groups render the amino-1,8-naphthalimide compound sufficiently soluble in a fluid such that visualization of the fluid by color or fluorescence is allowed. In one advantageous embodiment, the amino-1,8-naphthalimide is obtained from the mixture of 4-chloro-1,8-naphthalic anhydride with monoamine polyether.</p> |
