Fluorinated surfactants in overcoat compositions and elements containing same

A coating composition comprising an aqueous solution of:

• two or more surfactants;
• a hydrophilic binder;
• matte beads;
• and
• a lubricating agent;
• wherein one of the surfactants is represented by the following Formula (I):
• Rf—CH2CH2—S—(A)—D (I)
• where Rf is —(CF2)nCF3, when n represents the number of CF2 groups and is 3 or 5 in at least 40% of the Rf groups present, the remainder of Rf groups being an odd number up to 13;
• A is a divalent linking group that includes substituted alkylene or alkylene (N-alkylene)amide;
• and
• D is an anionic group or a cationic group;
• and
• wherein said composition is used in forming an overcoat layer in a photographic element that contains at least one distinct non-image-forming layer between the overcoat layer and any image-forming layer.

A photographic element comprising:

• a) a support,
• b) at least one image-forming layer;
• and
• c) an outermost overcoat layer comprising:
• i) two or more surfactants;
• ii) a hydrophilic binder;
• iii) matte beads;
• and
• iv) a lubricating agent;
• wherein one of the surfactants is represented by the following Formula (I):
• Rf—CH2CH2—S—(A)—D (I)
• where Rfis —(CF2)nCF3, where n represents the number of CF2 groups and is 3 or 5 in at least 60% of the Rf groups present, the remainder of Rf groups being an odd number up to 13;
• A is a divalent linking group that includes substituted alkylene or alkylene (N-alkylene)amide;
• and
• D is an anionic group or a cationic group.

A method of providing control of static charge for a photographic element, the method comprising the steps of providing a photographic element, coating its outermost layer with a fluorinated surfactant coating composition and drying said coating, said coating composition comprising:

• i) a mixture of two or more surfactants;
• ii) a hydrophilic binder;
• iii) matte beads;
• and
• iv) a lubricating agent;
• wherein one of the surfactants is represented by the following Formula (I):
• Rf—CH2CH2—S—(A)—D (I)
• where Rf is —(CF2)nCF3, where n represents the number of CF2 groups and is 3 or 5 in at least 40% of the Rf groups present, the remainder of Rf groups being an odd number up to 13;
• A is a divalent linking group that includes substituted alkylene or alkylene (N-alkylene)amide;
• and
• D is an anionic group or a cationic group;
• and
• wherein the photographic element contains at least one distinct non-image-forming layer between the overcoat layer and any image-forming layer, said non-image-forming layer containing a UV-absorbing compound.
