Compressed fluid formulation containing electroluminescent polymeric material

摘要

An imaging composition comprising a mixture of a solvent and a functional material; wherein the solvent is a compressed fluid and the functional material is an electroluminescent polymeric material which is dissolved, dispersed and/or solubilized in the compressed fluid; wherein the mixture is thermodynamically stable or thermodynamically metastable or both; wherein the functional material is solvent-free upon deposition on a substrate; and wherein the functional material forms a solid film upon deposition on the substrate.
