ABSTRACT:
Improved correction fluid for obscuring indicia on sheet material. Such fluid, which normally comprises a solution of pigmented thermoplastic resin, is rendered capable of obscuring typed, xerographically copied, or written ink indicia by using a solvent system having a refractive index of 1.410 or less. A preferred non-flammable system includes 20-40 volume percent 1,1,2-trichlorotrifluoroethane and correspondingly 80-60 volume percent heptane.
