The invention is directed to a screen-printable getter composition comprising: (a) glass frit; dispersed in (b) organic medium. The invention is further directed to a screen-printable thick film getter composition comprising: (a) glass frit; and (b) desiccant material; dispersed in (c) organic medium. The present invention further relates to a getter composition utilizing low-softening temperature glasses comprising, based on weight %, 1-50% SiO<SUB>2</SUB>, 0-80% B<SUB>2</SUB>O<SUB>3</SUB>, 0-90% Bi<SUB>2</SUB>O<SUB>3</SUB>, 0-90% PbO, 0-90% P<SUB>2</SUB>O<SUB>5</SUB>, 0-60% Li<SUB>2</SUB>O, 0-30% Al<SUB>2</SUB>O<SUB>3</SUB>, 0-10% K<SUB>2</SUB>O, 0-10% Na<SUB>2</SUB>O, and 0-30% MO where M is selected from Ba, Sr, Ca, Zn, Cu, Mg and mixtures thereof. The glasses described herein may contain several other oxide constituents that can substitute glass network-forming elements or modify glass structure.
