Water absorption resistant polyimide pastes (or solutions), are
particularly useful to make electronic screen printable pastes and the
electronic components made from these pastes. A group of soluble
polyimides and their solvents were discovered to be particularly
resistant to moisture absorption. These polyimide solutions optionally
contain polyimides also containing cross-linkable monomers and/or thermal
cross-linking agents. In addition, these polyimide pastes may optionally
contain adhesion promoting agents, blocked isocyanates, metals, metal
oxides, and other inorganic fillers. The polyimide pastes (or solutions)
of the present invention have a polyimide with a glass transition
temperature greater than 250.degree. C., have a water absorption factor
of less than 2%, and a have a positive solubility measurement.
