A color developer 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.
一种用于压敏或热敏记录纸的颜料开发剂,包括N-单取代磺酰胺,其在磺酰胺的氨基基团内含有至少一个电子吸引基团,该N-单取代磺酰胺可以是N-取代、N'-单或双取代磺酰胺的形式,或者是含有该N-单取代磺酰胺作为其功能或阻碍基团的多功能分子。当这些化合物与金属或金属化合物的源一起使用时,可以实现最大的颜色开发潜力。
