A white ink includes a hollow resin particle, one or more first organic solvents, an acrylic silicone-based resin, a surfactant; and water. The luminosity (L*) of each of a first dried film having a thickness of 2.2-2.8 m prepared by drying the white ink at 70 degrees C. and a second dried film having a thickness of 2.2-2.8 m prepared by drying the white ink at 90 degrees C. is 50 or greater and the decrease ratio of the luminosity (L*) of the second dried film to the first dried film is 10 percent or less.

The present invention relates to a water-based correction fluid comprising aa photocrosslinkable acrylate and/or methacrylate oligomer, ba photoinitiator, can opacifying agent, and dwater, eoptionally a photocrosslinkable acrylate and/or methacrylate monomer, and doptionally an additive, said fluid having a dry extract of between 40 and 80% by weight relative to the total weight of the fluid, advantageously between 54 and 66%, and forming 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.

It 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.
