Claims17
An electronic paste composition comprising:
- a) inorganic particles and
- b) a vehicle containing at least one compound having a molecular weight of about 200 to about 500 of the structure, ##STR5## or the structure, ##STR6## or the structure, ##STR7## or the structure, ##STR8## where R.sub.1 through R.sub.8, are independently selected from the group consisting of hydrogen, phenyl, alkyl containing 1 to 10 carbon atoms, and cycloalkyl containing 5 to 10 carbon atoms, with the proviso that at least one of R.sub.1 and R.sub.2 is different than hydrogen and at least one of R.sub.3 and R.sub.4 is hydrogen;
- X.sub.1 through X.sub.5, Y.sub.1 through Y.sub.5, Z.sub.1 through Z.sub.5, are independently selected from the group consisting of hydrogen, phenyl, alkyl, cycloalkyl, acyl, alkoxyl, carboxyl, carboxyl ester, and hydroxyl;
- and wherein said group each contains 10 or fewer carbon atoms;
- and n is 1 or 2.
