摘要: A thermosensitive recording medium comprises a substrate and a thermosensitive, coloring layer, provided on the substrate, comprising a binder, a colorless or light-colored electron-donating dye, an electron-accepting compound to react with the electron-donating dye and form a coloring matter and then an ester compound obtained from a fatty acid having 20 to 28 carbon atoms and a straight or cyclic alcohol, the ester having a melting point of 50 to 100 degree C. and one or more non-phenolic hydroxy group. It is improved in prevention from fogging and sensitivity.

摘要: A thermal transfer recording medium comprising a support and a heat-fusible ink layer, coated on the support, which comprises a colorant and a binder. The binder comprises a polyurethane having bisphenol units or a polyether having bisphenol units and an hydroxyl group at the terminals. The thermal transfer recording medium provides a transferred image with a high quality regardless of the transferring paper.

摘要: Isocyanuric acid triesters are prepared by isomerization of the corresponding cyanuric acid triesters. The starting cyanuric acid esters are dissolved in a polar solvent which is free of active hydrogen atoms, which contains a nitrogen or sulfur atom in the molecule and which has a boiling point not higher than 260.degree. C. The solution may optionally contain an alkali metal halide, an alkaline earth metal halide or an ammonium halide. Isomerization is carried out at a temperature of from 50.degree. to 200.degree. C.
