Abstract
The invention relates to an ink-jet ink composition for printing on a ceramic substrate comprising: (a) a liquid vehicle; (b) sub-micron particles of binding composition having a melting point below 6000 C; and (c) sub-micron particles causing an etch-like effect, said sub-micron particles are selected from metal oxide particles, high melting point frit particles, and a combination thereof, said sub-micron particles causing an etch-like effect have a melting point of at least 500 C above the melting point of said sub-micron particles of binding composition. The invention further relates to a printing process using such ink and to a ceramic substrate printed with a pattern or image having an etch-like effect, by means of the printing process.
