THERMOSENSITIVE RECORDING MATERIAL

摘要

A thermosensitive recording paper useful for thermosensitive recording comprising a substrate and a thermosensitive recording layer, with an undercoat layer interposed therebetween which contains 10 to 40 parts of a binder and 60 to 90 parts by weight of crosslinked polymer microparticles. The microparticles have a particle diameter of 0.2 to 5.0 mu m and a ratio of weight average diameter to number average diameter of 2.0 or less.
