The invention relates to an overcoat composition for an imaged image-recording element, the overcoat composition comprising an aqueous carrier, an optional humectant, an optional surfactant, and 0.05 to 20 weight percent, based on the total weight of the overcoat composition, of an addition polymer having an acid number greater than 110. The invention also relates to a method of making an imaged image recording element having a transparent overcoat, which method comprises forming an image on the image recording element and applying over the image an overcoat composition of the present invention.
The overcoat compositions of the invention provide advantageous stain resistance.
