ABSTRACT:
A carbonless paper solvent, a method of solubilizing a chromogenic material, and a recording sheet, all utilizing triisopropyltoluene, are the subject of the present invention. Triisopropyltoluene may be obtained by the alkylation of toluene and the resulting product will normally contain the 2,3,5, the 2,4,5 and the 2,4,6 isomers. The triisopropyltoluene may be combined with other known dye solvents such as alkylated naphthalenes, diarylmethanes and alkylated biphenyls to present a carbonless paper solvent or it may be utilized alone. The triisopropyltoluene will normally be present in a quantity of at least 40% by weight of the total solvent. A recording sheet may be formed by a paper which is coated with a continuous layer of microcapsules containing chromogenic marking material and a solvent comprising triisopropyltoluene.
