Abstract
An aqueous overcoating composition which is able to adhere strongly to an oil-based ink printed on a sheet, enhances the film properties of the oil-based ink as to, for example, gloss, rub resistance and the like, prevents offset and blocking occurring at the time of stacking and the like after printing, and strikingly improves setting and drying of the oil-based ink so that it is possible to start the ensuing work of the after-treatments of printed matter. The composition is coated in a thin film on a wet sheet surface just printed with an oil-based ink, on a printing press or in a printing operation.
