Abstract
There is provided an electroactive system for forming an electroactive layer. The system includes: (a) a first electroactive material; (b) a facilitation additive; and (c) a first liquid medium. The facilitation additive is present during baking in an amount sufficient to enable the electroactive layer made therefrom to effectively resist mixing with a second liquid medium applied thereover after the electroactive system is deposited and baked at a temperature less than 350° C. for a predetermined time.
Claims5
A composition comprising a mixture of:
- (a) a first electroactive material;
- (b) a facilitation additive having no crosslinkable groups;
- and
- (c) a first liquid medium;
- wherein the facilitation additive is present during baking in an amount sufficient to enable an electroactive layer made from the composition to effectively resist mixing with a second liquid medium applied over the electroactive layer after the composition is deposited onto a workpiece and baked at a temperature less than 350° C. for a predetermined time;
- wherein the facilitation additive has a vapor pressure at 225° C. that is in a range of 10−3 Pa to 40 Pa.
