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.

Abstract: The present invention provides an anti-fogging agent for the surface of a thermoplastic resin sheet which exerts the following excellent effects:(1) The effect of inhibiting fogging on the surface of the sheet due to the condensation of vapor can last over an extended period of time;(2) Excellent blocking resistance and coating stability make the anti-fogging surface less peelable in the procedure of heating it over a heating plate in a direct heating process so that it is formed into various shapes; and(3) The incorporation of a polyvalent alcohol having wetting properties in a predetermined amount provides excellent antistatic properties. The present invention provides an anti-fogging thermoplastic resin sheet treated with the foregoing anti-fogging agent.
