| abstract | PRESSURE-SENSITIVE RECORD MATERIAL ABSTRACT OF THE DISCLOSURE A pressure-sensitive record material comprising the colorless chromogenic dye Pyridyl Blue mixed with and adsorbed onto a pigment which is coated on a substrate sheet, and capsules containing an acidic resin dissolved in a suitable solvent, the capsules being coated on the same or an additional sheet. This "reverse" system (where the acidic resin rather than the dye is encapsulated) provides an improved community of properties, including improved image strength, print stability (fade resistance) and resistance to degradation. Pyridyl Blue is a mixture of the isomers 7-(1-ethyl-2-methylindol-3-yl)-7-(4-diethylamino-2-ethoxyphenyl)-5,7-dihydrofuro[3,4-b]pyridin-5-one and 5-(1-ethyl-2-methylindol-3-yl)-5-(4-diethylamino-2-ethoxyphenyl)-5,7-dihydrofuro[3,4-b]pyridin-7-one. |
