Abstract
1398199 Pressure-sensitive compositions MONSANTO CO 9 Feb 1973 [11 Feb 1972] 6438/73 Heading C4A [Also in Division D2] In the development of colour from a colourless chromogenic compound by reaction with a sensitizing agent, the reaction is carried out in the presence of a liquid comprising a solvent which is a terphenyl, partially hydrogenated terphenyl, (C 1-4 alkyl)-substituted terphenyl, or mixture thereof having at least 65% aromaticity. Aromaticity of 65-85% is preferred. The solvent may be liquid or solid at room temperature and if solid must be used with a diluent. The diluent may be a mineral or vegetable oil, an aromatic naphtha, C 1-12 alkyl benzene, benzyl biphenyl, or C 1-6 alkylaryl indane, in an amount up to 3 times that of the terphenyl. Preferably the chromogen is in solution in the liquid, e.g. in microcapsular form. Numerous known chromogens are listed. The sensitizing agent is a known solid acidic material such as an acid clay or an organic polymer.
