ABSTRACT:
The substantial reduction of aerosol generation in ink-jet printing is achieved with the addition of a viscoelastic polymer to ink-jet ink compositions. The viscoelastic polymer component is employed at a concentration within the range of 5 to 10 ppm. Examples of suitably employed viscoelastic polymers are polyacrylamides having weight average molecular weights ranging from about 10,000 to 5,000,000 and polyvinylpyrrolidones having molecular weights ranging from about 3,000 to 1,000,000, as well as mixtures thereof. The addition of a viscoelastic polymer component serves to increase the extensional viscosity and the surface tension of the ink, thereby preventing or at least delaying the fragmentation of the tail of an ink droplet ejected by an ink-jet printer. Accordingly, any breakoff remnants are provided with sufficient mass and velocity such that trajectory control is not abandoned to aerodynamic forces.
