摘要： The process for producing microcapsules comprises forming capsules having a wall film composed of an amine-aldehyde polycondensate in a system in which a hydrophobic core substance is dispersed or emulsified in an acid aqueous solution containing an anionic colloidal substance, said anionic colloidal substance being an anionic water-soluble copolymer composed of acrylic acid, styrenesulfonic acid, and alkyl acrylate or alkyl methacrylate. The present invention decreases the large particles present in the capsule slurry, and provides microcapsule which are excellent in emulsification power, emulsification stability, particle size distribution, impermeability of capsule-wall film and workability.

摘要： 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.
