More Information
Summary:The present invention relates to thermographic record compositions and to novel color developers for thermographic compositions consisting of: the compounds of formula: in which R represents: H, alkyl, NO2, halogen, aryl, NH2, OH, COOH, HSO3, NR1R2, COOR3, OR4 (R1, R2, R3, R4=alkyl or aryl), X represents H or a group possessing a labile H capable of forming a stable anion by loss of a proton H+, or their salts of formula, when X=H: in which R and n are as defined hereinabove and M+ represents a metal cation. The invention is more particularly applicable to supports for recording data.
