Abstract
A pressure-sensitive recording material which is excellent in several properties and prepared at a low cost. The pressure-sensitive recording material of the invention is applied with pressure-rupturable microcapsules containing a solution of dyestuff in a solvent fraction having a boiling range of 265.degree. C. to 360.degree. C. (converted to atm. press.) which is obtained by treating a raw material fraction in the presence of an acid catalyst. The raw material fraction is obtained from the product of thermal cracking of petroleum hydrocarbons at a temperature of 700.degree. C. or above and mainly contains the distillate having boiling points in the range of 75.degree. C. to 198.degree. C. and the main components thereof are monocyclic aromatic hydrocarbons (excluding aromatic olefins) and monocyclic aromatic olefins.
