Abstract
A ceramic ink for digital printing, preferably for inkjet printing, comprises at least one solid part comprising at least one ceramic pigment or dye; and at least one liquid part into which said ceramic pigment or dye is dispersed and comprising one or more vehicles and/or one or more dispersants; wherein at least one of either the one or more vehicles or the one or more dispersants comprises one or more organic or inorganic silicon compounds.
Claims18
1) Ceramic ink for digital printing, comprising:
- at least one solid part comprising at least one ceramic pigment or dye;
- and
- at least one liquid part into which said ceramic pigment or dye is dispersed and comprising one or more vehicles and/or one or more dispersants;
- wherein
- at least one of either said one or more vehicles or said one or more dispersants comprises one or more organic or inorganic silicon compounds.
14) A method for the manufacture of a ceramic manufactured article, comprising:
- preparing a ceramic semi-finished product;
- printing the ink according to one or more of the preceding claims on a surface of said ceramic semi-finished product;..and
- heat treating said ceramic semi-finished product at a temperature above 500° C. to obtain said ceramic manufactured article;
- wherein
- said ceramic manufactured article producing an odor emission of less than 1000 OUE/m3 and/or an atmospheric emission of total organic carbon (TOC) of less than 50 mg/Nm3 and/or wherein said one or more organic or inorganic silicon compounds form on the surface of said ceramic manufactured article at least one odorless compound selected from a list comprising:
- SiOx, SiCx, SiCxOy, SiNx, SiNxOy, SiBx, SiBxOy, wherein x and y are between 0 and 6.
15) A use of one or more organic or inorganic silicon compounds as a medium and/or dispersant in ceramic inks for digital printing.
