PERFECTED INK FOR LATENT AWARENESS OF SURFACES ON WHICH IT IS APPLIED

摘要

The present invention relates to latent sensitizing inks for application to selected areas of substrates by conventional printing methods. /P P These inks comprise a vehicle consisting of an oleophilic organic acid anion in the uncured state, comprising a cationic ion and, in association with this vehicle, a diluent, a particulate filler, a terpene hydrocarbon polymer resin thermoplastic and at least one coloring generator component. /P P This ink makes it possible in particular to obtain better image formation characteristics and the use of a smaller amount of filler in the composition.
