Abstract

A ceramic printing ink is provided that is suitable for application using an inkjet printing process to produce a coating on glass ceramics. The ink includes a glassy material of glass particles and pigment particles. The glass particles are present in a ratio of total weight to the pigment particles of at least 1.5 and less than 19. The glass particles have an equivalent diameter d90 ranging from at least 0.5 μm to at most 5 μm. The ink has an effective coefficient of linear thermal expansion, α20-300,eff, in a range from 6.5*10−6/K to 11*10−6/K.
