Correction fluids are provided which include an opacifying pigment, a water-fast ink fixing agent including a cationic non-film- forming polymer, a binder including a film-forming polymer compatible with the ink fixing agent, and water. The new correction fluids have improved "bleed" resistance when used to correct water-fast inks, such as ball-point pen inks.
Fluides de correction qui comportent un pigment opacifiant, un fixateur d'encre presque imperméable à l'eau comprenant un polymère non filmogène cationique, un liant comprenant un polymère filmogène compatible avec le fixateur d'encre et de l'eau. Lesdits nouveaux fluides de correction ont une résistance améliorée au mélange avec l'encre à corriger lorsqu'ils sont utilisés pour corriger des encres presque imperméables à l'eau, telles que des encres pour stylo à bille.
