ABSTRACT:
The invention relates to an improved color paste for the manufacture of internally printed, curved laminated glass panes.
Prior art color pastes cause problems with respect to adhesion and optical accuracy or require a higher technical complexity during the baking process for producing internally printed laminated glass panes.
Color pastes which constitute the invention and overcome the previous drawbacks are characterized by a print medium which contains 5,6,8-trihydroxy-1,4-naphthoquinone in addition to solvents.
