  • Latent sensitizing ink
    Patent number: 4205865
    Abstract: 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 a particulate filler. The latent inks also include at least one color-generating component. A preferred ink comprises as an additional component a polymeric, hydrocarbon, thermoplastic terpene resin which enhances imaging characteristics and allows the use of reduced filler loadings in the composition.
