PURPOSE:To obtain a pressure sensitive copy material having excellent coloring performance and a low cost by combining specific solvent and specific developer. CONSTITUTION:5-50vol.% of one or more types of alkyl benzene having 3cSt or less of viscosity at 40 deg.C of solvent of solution and 150 deg.C of boiling point of normal pressure conversion, and 50-95vol.% of aromatic hydrocarbon having at least to noncondensation or condensation type aromatic ring having 260 deg.C or higher of boiling point of normal pressure conversion, 3cSt or more of viscosity at 40 deg.C and/or chlorinated paraffin oil having 3cSt or more of viscosity of 40 deg.C are contained. A developer is selected from a group consisting of aromatic carboxylic acid, its polymer, its metal salts, polyvalent metallized carboxyl modified terpenephenol resin and its derivatives as well as their mixtures. |
