Pyrolytic precursors of coupling component can be applied to th ermally developable diazonium type systems.α -, β -, and γ-resorcylic acids and 2, 4-dimethy1-3, 5-bis(ethoxycarbonyl)pyrrole were chosen as a precursor. The 1 st order kinetic constants (k) and activation energies in the pyrolytic decomposition reaction of them were obtained according to Niwkirk's method. The temperature at which a tenth amount of γ-resorcylic acid (2, 6-dihydroxybenzoic acid)decomposed corresponded to the thermo-sensitivity of the system. It was concluded that the storage stability of the system could be estimated from the k value of a pyrolytic precursor at room temperature.
