<p>Latent, sensitizing inks for application to selected areas of substrates by conventional printing methods. The inks comprise a unique vehicle component which is a non-polymeric, oleophilic, organic Arrhenius acid anion having a cationic counter-ion and, in combination with said vehicle component, a thinner and an oil-receptive, particulate filler. The latent inks also include at least one color-generating component. The ratio of filler to the vehicle component is about 0.5:1 to about 6:1.</p> |
