Abstract

A water-based ink composition for glass and ceramic surfaces contains an acrylic silicone resin emulsion, pigment, dispersant, and water-based solvent. The water-based ink composition may further contain a thixotropic agent and/or resin beads. The ink composition allows writing made with it to sufficiently demonstrate excellent water resistance, hot water resistance, and scratch resistance even on glass and ceramic surfaces, and to remain sufficiently legible even after the glass products or ceramics are cleaned repeatedly.
