Abstract: The present disclosure relates to a water-based correction fluid comprising a—a photocrosslinkable acrylate and/or methacrylate oligomer, b—a photoinitiator, c—an opacifying agent, and d—water, e—optionally a photocrosslinkable acrylate and/or methacrylate monomer, and f—optionally an additive. The fluid has a dry extract of between 40 and 80% by weight relative to the total weight of the fluid, advantageously between 54 and 66%, and forms a film after drying comprising at least 40% by weight of opacifying agent relative to the total weight of the film, advantageously between 40 and 80% by weight. The present disclosure also relates to a device for applying the correction fluid and a process for covering a mark on a paper support using the correction fluid.
