ABSTRACT:
A coating composition for use in a photographic element, the composition comprising an aqueous solution of: two or more surfactants; a hydrophilic binder; and optional matte particles; wherein one of the surfactants is represented by the following Formula (I):in-line-formulae description="In-line Formulae" end="lead"?Rf—CH2CH2—(B)y-A (I)in-line-formulae description="In-line Formulae" end="tail"?where Rfis F(CF2CF2)n— and n is 3 and 4 or 3, 4, and 5, and the fraction of all Rfwith n=3 is at least 40%;B is a divalent linking group; y is 0 or 1; and A is an anionic group with a counterion or an amphoteric group. A photographic element containing the coating composition is also disclosed.
