Abstract

There are disclosed thermoplastic inks in the nature of high viscosity, tacky pastes which exhibit high cohesive strength, high pressure sensitivity at low temperatures, high thermal stability and low affinity for silicone surfaces. These properties make the inks particularly useful in those printing processes involving multiple elastomeric transfer members, in particular, those processes wherein silicone transfer members print successive colors onto a silicone collector which in turn transfers the multicolored print in a single step to ware or decal paper. The ink formulations consist essentially, in weight percent, of: PA0 (a) 50-80% of a pigmented, vitreous, inorganic flux; PA0 (b) 2-20% of a selected organic polymer; PA0 (c) 5-25% of a selected plasticizer; PA0 (d) 2-20% of a selected amorphous tackifying resin; and optionally, PA0 (e) up to 20% of an organic wax.
