Abstract
A pressure sensitive manifold paper is prepared with use of microcapsules having enclosed therein an organic solvent, a color former contained in the solvent, and an alkylphenol compound and/or a mercaptan added to the solvent. The paper affords prints resistant to light and has a color forming layer which remains free of coloration and gives prints of original color even when exposed to light.
