Abstract
PURPOSE: To avoid the rupture of a micro capsule and the color displacement by using more than one kind of either aromatic carboxylic acid or its metallic salt as an electron accepting compound of a pressure sensitive recording paper.
CONSTITUTION: A recording layer applied with an electron supplying non color dyestuff and an electron accepting compound and the layer containing a solvent to dissolve at least either one of the said electron supplying non color dyestuff or the said electron accepting compound and retained by the separate supporting materials with the both layers opposing with each other, to make a pressure sensitive recording sheet, and at least either one of an aromatic carboxylic acid or the metallic salt is used as the electron accepting compound. 2,4-dichloro benzoic acid, p-isopropyl benzoic acid, 2,5-dinitro benzoic acid, etc. can be taken as examples. They must have a salicylic acid derivative, particularly having substitution radicals at third or fifth, and at the same time, the total carbon atomic number of these substitution radicals must preferably fall within 4W20.
