Photocurable inks and primers for automotive interior applications and glass articles comprising same

A glass article comprising:

• a glass substrate having a first major surface and a second major surface, the second major surface being opposite the first major surface;
• and
• an opaque layer disposed on the second major surface, the opaque layer comprising a photocurable ink comprising at least 11 wt % of a pigment, wherein:
• the opaque layer is resin free and TPO free,
• the opaque layer comprises a thickness less than or equal to 15 μm and an optical density greater than or equal to 5.0, and
• after curing solely via exposure to ultraviolet (“UV”) radiation, the opaque layer exhibits:
• a pencil hardness greater than or equal to 3H, when measured according to ASTM 3363, and
• an adhesion to the glass substrate greater than or equal to 4B, after being subjected to a temperature of 85° C. at 95% relative humidity for a period of at least 500 hours, when tested according to ASTM 3359.

A method of fabricating a glass article, the method comprising:

• depositing an ink primer onto a first major surface of a glass substrate at a first deposition temperature less than or equal to 65° C. using a first inkjet printhead, wherein during the depositing, the ink primer has a viscosity less than 13 cPs, wherein the ink primer comprises greater than or equal to 2 wt % and less than or equal to 10 wt % of an adhesion promoter configured to bond to glass;
• exposing the ink primer to a first light source to at least partially cure the ink primer;
• depositing an ink composition onto the ink primer at a second deposition temperature less than or less than or equal to 65° C. using a second inkjet printhead, wherein during the depositing, the ink composition has a viscosity less than 13 cPs;
• and
• exposing the ink composition to a second light source to at least partially cure the ink composition.
