摘要:
Nonpolymeric fluorochemicals defined as by the following Structure I are useful in thermally developable materials. The fluorochemicals are defined as follows: RfnullRnullN(R1)(R2)(R3)nullXnullnullnull(I) wherein Rf is a straight or branched chain perfluoroalkyl group having 4 to 18 carbon atoms, R is a divalent linking group comprising at least 4 carbon atoms and a sulfide group in the chain, R1, R2, R3 are independently hydrogen or alkyl groups or any two of R1, R2, and R3 taken together can represent the carbon and nitrogen atoms necessary to provide a 5- to 7-membered heterocyclic ring with the cationic nitrogen atom, and Xnull is a monovalent anion.
摘要:
Antistatic compositions include a fluorochemical that is a reaction product of RfnullCH2CH2nullSO3H with an amine wherein Rf comprises 4 or more fully fluorinated carbon atoms. These antistatic compositions can be formulated in organic solvent-based conductive coating compositions, with or without hydrophobic binders, that can be used to form conductive layers in thermally developable materials including thermographic and photothermographic materials.
