HEAT-SENSITIVE RECORDING MATERIAL

摘要: PURPOSE:To prepare a low cost heat-sensitive recording material which is free from fog phenomenon and improved in storability by providing layer primarily composed of diazoamino compound, coupling ingredients encapsulated with specific substance heat-fusible color forming assistant on support. CONSTITUTION:A prepared compound (e.g.: formulaI, formula II), ingredient Naphthol AS) hydrophobic high molecular heat softening temperature 50-150 deg.C, obtained vinyl monomer acetate/methyl methacrylate copolymer) or non-polar waxlike melting point 50- 150 deg.C paraffin wax) oleamide) supoort. Fog can be prevented the without detriment to thermal sensitivity layer. Since this formed aqueous coating, its manufacturing reduced eliminating necessity for an expensive organic solvent.
