Abstract
The present invention provides a fast drying jet ink composition comprising an organic solvent, a colorant, a polyamine, and an acidic resin. The acidic resin preferably has an acid number of from about 10 to about 250. Examples of suitable polyamines include dendrimers and aminoacrylates. The jet ink composition can be used to print on glass surfaces that have a condensation of moisture on them. The printed messages do not easily rub off after exposure to humid conditions. The messages printed on glass can be washed off by a caustic solution.
