摘要:
This invention provides a pressure- and heat-sensitive multilayer copying paper useful as a recording material for various types of recording machines, such as a portable terminal. A pressure- and heat-sensitive multilayer copying paper comprises: an upper paper member composed of: a substrate sheet; a layer provided on a front surface of the substrate sheet comprising a organic compound and an acidic organic compound; a layer provided on a back surface of the substrate sheet comprising a organic compound, microcapsules encapsulating the organic compound and a thermomeltable material; and an overcoated protective layer placed on the layer provided on a back surface of the substrate sheet; and a lower paper member: a substrate sheet; a layer provided on a front surface of the substrate sheet comprising at least one acidic organic compound which forms color in case that it reacts with the organic compound.
