摘要:
A heat-sensitive recording sheet comprising:(a) a support sheet;(b) a thermo-sensitive color forming layer formed on the said support sheet, said thermo-sensitive color forming layer comprising a colorless to pale color leuco dye and an acidic material capable of coloring the colorless to pale color leuco dye when heat is applied thereto;(c) an over-coat layer formed on the said heat-sensitive, color-forming layer, said over-coat layer comprising an inorganic silicate or a mixture of an inorganic silicate and a water-soluble, high-molecular compound or a slightly water-soluble high-molecular compound.The said heat-sensitive recording sheet has a reduced property of sticking of coatings and/or dreg to a thermal head during recording and gives a developed image which is not faded by contact with plasticizer, oil, fat or water.
