Abstract: An object of the present invention is to provide a method for producing sugar and ethanol from sugar cane, in which almost all of energy to be consumed in the production processes of the sugar, the ethanol and the like can be supplied by the energy obtained by burning a pressed residue of sugar cane, yet without decreasing the sugar amount to be produced.

Abstract: A heat-sensitive recording material having an improved color image-forming property and an enhanced gloss and resistance to water, oily substances and plasticizers, is provided with a heat-sensitive color-forming layer formed on a substrate surface and comprising a substantially colorless dye precursor, a color-developing agent and a binder; an intermediate layer formed on the color-forming layer and comprising a hydrophilic polymeric material and a pigment; a glossy surface layer formed on the intermediate layer and comprising a hydrophobic polymeric material having a glass transition point of 60.degree. C. or more, and a lubricant; and optionally, an additional intermediate layer formed between the color-forming layer and the intermediate layer and comprising at least one member selected from hydrophilic polymeric materials and hydrophobic polymeric materials.

Abstract: A heat-sensitive recording material having a superior resistance against water, plasticizers, and oily substances, is provided with a heat-sensitive color-forming layer formed on a surface of a substrate sheet and comprising a dye precursor, a color-developing agent, and a binder; and a protecting layer formed on the heat-sensitive color-forming layer and comprising (A) a polyvinylalcohol resin, (B) a water-soluble cross-linking agent, (C) at least one organic boron-containing polymer of the formula (I): ##STR1## and optionally (D) an acetoacetylated polyvinylalcohol resin.
