Patent ID: 7794790

Claim:
A method for printing a fluid material using a continuous jet printing technique, wherein the material is passed under pressure from a reservoir through a channel to at least one outflow opening of the channel, after which the material is passed through the outflow opening, whereby the pressure in at least a part of the channel upstream of the outflow opening is in the interval of 15-600 bars [≡1510 5 to 60010 5 Pa], and whereby the fluid material comprises a curable composition which at the time of flowing out through the outflow opening has a shear viscosity at 22° C. in a range of 150-400 mPas and comprises (a) a component A in an amount in the range of from 1-15 wt % which component A has a dielectric constant larger than 15 (at 0° C.), (b) an ionically dissolved lipophilic salt in an amount in the range of from 1-15 wt %, (c) optionally (a) coating additive(s) in an amount of at most 10 wt %, and (d) for the remaining part a liquid component B which comprises a curable monomer and/or a curable oligomer, which liquid component B has a shear viscosity (at 22° C.) in the range of from 50-1500 mPas, whereby liquid components A and B are compatible with each other, and all amounts are based upon total composition.
