摘要：
Compositions are provided comprising a continuous liquid aqueous medium having dispersed therein a polydioxythiophene and at least one colloid-forming fluorinated polymeric acid. Films from invention compositions are useful as buffer layers in organic electronic devices, including electroluminescent devices, such as, for example, organic light emitting diodes (OLED) displays.
