Ink jet printing on a non-absorbent substrate involves a wet primer having a primer viscosity. The wet primer is applied on the non-absorbent substrate. An ink jet ink having an ink jet viscosity lower than the primer viscosity is jetted over the wet primer while the primer is still wet. The wet primer and ink are simultaneously cured on the substrate.

An ink composition for additive manufacture of silica aerogel objects essentially consists of a gellable silica sol containing an admixture of 30 to 70 vol.% of a mesoporous silica powder in a base solvent. The mesoporous silica powder has a particle size range of 0.001 to 1 mm and a tap density of 30 to 200 kg/m3 and comprises at least 10% by weight of silica aerogel powder. The composition has a yield stress in the range of 30 to 3000 Pa and a viscosity of 5 to 150 Pa.Math.s at a shear rate of 50 s−1. Furthermore, the composition has shear thinning properties defined as a reduction in viscosity by a factor between 10 and 103 for an increase in shear rate by a factor of 104 to 105. A method of additive manufacturing of a three-dimensional silica aerogel object by direct ink writing comprises providing such ink composition, forcing the same through a convergent nozzle, thereby forming a jet of the ink composition which is directed in such manner as to form a three-dimensional object by additive manufacturing. After initiating and carrying out gelation of the gellable silica sol constituting said object, a drying step yields the desired three-dimensional silica aerogel object.

A pigment composition contains: an azo pigment that is a reaction product between a coupler and a base; and a pigment derivative, and a content of o-anisidine derived from the coupler is less than or equal to 20 mg/kg in the entire pigment composition. A method for producing the pigment composition includes, after reaction between a coupler and a base to generate an azo pigment, or during the reaction between the coupler and the base, adding a remover for o-anisidine derived from the coupler.
