    • 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.degree. to 300.degree. 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 recording material of the invention has scarcely offensive odor and can develop a dense color with a higher color developing rate.
    • 一种压敏记录材料,其是通过使用当染料前体与电子接受显色剂接触时产生颜色的给电子染料前体制备的。 压敏记录材料的特征在于,用于所述染料前体的溶剂包括烷基化部分,其通过用至少一个具有1至5个碳原子的烷基烷基化副产物部分制备,副产物部分含有 该成分在大气压的基础上在255〜300℃的沸点范围内,并且在从乙烯和苯或甲苯生产乙苯或乙基甲苯的方法中得到。 本发明的压敏记录材料几乎没有异味,并且可以产生具有更高显色速率的致密颜色。
