Color developers for pressure-sensitive or heat-sensitive recording papers |
摘要 |
Color developers for use in pressure-sensitive or heat-sensitive recording papers comprise N-monosubstituted sulfonamides which contain at least one electron-withdrawing group within five atoms of the amido group of the sulfonamide. The N-monosubstituted sulfonamide may be in the form of an N-substituted, N'-mono or di-substituted sulfamide, or a polyfunctional molecule containing such an N-monosubstituted sulfonamide as the functional or impeding group thereof. The maximum color developing potential is realized when these compounds are used in conjunction with a source of metal or metal compound.
