摘要： A thermographic recording process in which a dye is produced by bringing image-wise into reactive contact with the aid of heat a dye precursor compound and a compound with acid reaction corresponding to the following general formula: ##EQU1## wherein : Z represents the necessary atoms to close an unsubstituted benzene nucleus, a halogen-substituted benzene nucleus or a nitro-substituted benzene nucleus, andR represents an unsubstituted aliphatic group containing at least 4 carbon atoms, a cycloaliphatic group or an aliphatic group substituted with hydroxyl, with an etherified hydroxyl group or with an acyloxy grup.

摘要： A thermographic recording process in which a dye is produced by bringing image-wise into reactive contact with the aid of heat an organic acid-reacting compound with a dye precursor compound corresponding to the following general formula:X = Ar - CH = N - R.sub.1wherein:Ar represents a bivalent aromatic nucleus,R.sub.1 represents an aryl group andX represents a ##STR1## group wherein each of R.sub.2 and R.sub.3 (same or different) represents an alkyl group, a cycloalkyl group, an aralkyl group, or an aryl group or R.sub.2 and R.sub.3 together represent the necessary atoms to close a nitrogen-containing heterocyclic nucleus.

摘要： A thermographic recording process in which a methine dye is produced by bringing image-wise into reactive contact with the aid of heat an acid-reacting compound with a dye precursor compound corresponding to the following general formula: ##EQU1## wherein: R.sub.1 represents (1) a substituted aryl group, at least one substituent of the substituted aryl group being an ether group R.sub.6 --O-- in which R.sub.6 represents a hydrocarbon group including a substituted hydrocarbon group or (2) a heterocyclic group including a substituted heterocyclic group,R.sub.2 represents a substituted aryl group, at least one substituent of the substituted aryl group, being an ether group R.sub.6 --O--, in which R.sub.6 represents a hydrocarbon group, including a substituted hydrocarbon group, a heterocyclic group including a substituted heterocyclic group, or a ##EQU2## group in which Z represents the necessary atoms to close a heterocyclic nucleus including a substituted heterocyclic nucleus,R.sub.3 represents (1) a --XH or --X--R.sub.7 group, in which X is oxygen or sulphur and R.sub.7 is an organic group, (2) a ##EQU3## group wherein in each of R.sub.8 and R.sub.9 (same or different) represents hydrogen or an alkyl group, a cycloalkyl group, an aralkyl group, or an aryl group or R.sub.8 and R.sub.9 together represent the necessary atoms to close a nitrogen-containing heterocyclic nucleus, or (3) a ##EQU4## group in which R.sub.10 represents an alkyl group including a substituted alkyl group, or a cycloalkyl group including a substituted cycloalkyl group, an aralkyl group including a substituted aralkly group, an aryl group including a substituted aryl group, a heterocyclic group including a substituted heterocyclic group and in which R.sub.11 represents hydrogen or represents a group enumerated in the definition of R.sub.10, or R.sub.11 and R.sub.10 together represent a sultam group,Each of R.sub.4 and R.sub.5 (same or different) represents hydrogen, a C.sub.1 -C.sub.5 alkyl group, a cycloalkyl group, an aralkyl group or an aryl group,n is 0 or 1, andm is 0 or 1.
