摘要
The correcting material for typewriter script is in sheet or strip form with a paper or foil carrier for lifting an incorrectly typed symbol from a sheet of paper with the aid of an adhesive substance. The correcting layer comprises a dry adhesive with microcapsules embedded in it which contain the finest droplets of a solvent for this dry adhesive. The capsules are broken open by the impact of the type so that the solvent is released and dissolves the adhesive thereby enabling the symbol tobe lifted from the sheet.
