PROBLEM TO BE SOLVED: To provide a thermal record medium whose heat energy necessary for coloring is lowered and a method for forming the record medium. SOLUTION: This record medium comprises a heat sensitive layer which contains a microencapsulated diazonium salt, a coupler, a basic compound, and a sensitizer. The sensitizer contains at least one kind selected from among n-propyl 4-hydroxybenzoate isopropyl 4-hydroxybenzate, and isobutyl 4-hydroxy benzoate. This is a coating liquid which contains a microencapsulated diazonium salt, a coupler, a basic organic substance, a sensitizer. The sensitizer 4 is formed by a coating method by using a coating liquid which contains at least one kind selected from among n-propyl 4-hydroxy benzoate, isopropyl 4-hydroxy benzoate, and isobutyl 4-hydroxybenzoate. |
