Beschreibung
Zusammenfassung:	A fluorinated polymer comprising at least three different groups within the polymer chain derived from reactive monomers, the monomers comprising: (a) a fluorinated, ethylenically unsaturated monomer; (b) a hydroxyl-containing, ethylenically unsaturated monomer; and (c) a polar, ethylenically unsaturated monomer. The fluorinated polymers provide a surfactant that is particularly useful in thecoating of polymeric layers. The surfactants can reduce surface anomalies, such as mottle when used to coat photothermographic and thermographic elements from certain solvent systems. The present invention also provides photothermographic and thermographic elements comprising the foregoing fluorinated polymers.
