A method of forming an overcoat layer. The method comprises providing a substrate having an imaging structure formed thereon, the imaging structure comprising (i) a charge transport layer and a charge generating layer, or (ii) an imaging layer comprising both charge generating material and charge transport material. An overcoat composition is deposited on the imaging structure, the overcoat composition comprising a charge transport molecule, a fluorinated building block, a leveling agent, a liquid carrier and optionally a first catalyst. The fluorinated building block is a fluorinated alkyl monomer substituted at the &#x3b1; and &#x3c9; positions with a hydroxyl, carboxyl, carbonyl or aldehyde functional group or the anhydrides of any of those functional groups. The overcoat composition is cured to form an overcoat layer that is a fluorinated structured organic film, the curing comprising treating an outer surface of the overcoat composition with at least one cross-linking process. The crosslinking process forms a cross-linking gradient in the overcoat layer. If the overcoat composition comprises the first catalyst, there is an insufficient amount of the first catalyst to fully cross-link the overcoat layer.
