EMAILZUSAMMENSETZUNG FÜR DIELEKTRISCHE SCHICHTEN, DARIN ENTHALTENE WEISSE PIGMENTE MIT VERBESSERTER BENETZBARKEIT UND PLASMAANZEIGETAFEL MIT DER DIELEKTRISCHEN SCHICHT |
摘要 |
The invention refers to an enamel composition for producing reflecting dielectric layers in plasma display panels, comprising as layer forming constituants 70 to 97 % by wt. of a glass frit composition and 3 to 30 % by wt. of a particulate whitening material. The whitening material comprises one or more thermally deactivated white pigments, which have been made by a process comprising heating of at least one white pigment in the absence or presence of a glass frit having a softening temperature of less than 600 DEG C at a temperature of 600 to 1000 DEG C for 0,1 to 10 hours. The invention further refers to a method for improving the wettability of white pigments by the above said thermal treatment. The enamel is used for producing a reflecting white dielectric layer in plasma display panels. |
