发明名称 Pressure-sensitive recording material.
摘要 <p>A pressure-sensitive recording material of the type . which is prepared by using an electron donating dye-precursor that produces a color when the dye-precursor is brought into contact with an electron accepting color developer. The pressure-sensitive recording material is characterized in that the solvent for said dye-precursor comprises an alkylated fraction which is prepared by alkylating a by-product fraction with at least one alkyl group having 1 to 5 carbon atoms, the by-product fraction containing the components within the boiling range of 255 to 300°C on the atmospheric pressure basis and being obtained in the process for producing ethylbenzene or ethyltoluene from ethylene and benzene or toluene. The pressure-sensitive recordin'g material of the invention has scarcely offensive odor and can develop a dense color with a higher color developing rate.</p>
