摘要： A thermal recording material composed of a support of foamed polystyrene sheet and a thermal color-developing layer formed thereon. It is highly sensitive and superior in image durability, with a low level of fogging by heat. When it is used as labels for polystyrene food containers and packages, it permits their recycling without necessity of removing labels. In addition, it has good water resistance owing to corona treatment on the foamed polystyrene sheet.

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.
