PROBLEM TO BE SOLVED: To provide a rust preventive coating composition precursor, from which a rust preventive coating composition can be obtained easily using polyaniline powder.SOLUTION: Provided is a rust preventive coating composition precursor comprising polyaniline, polyvinylbutyral, and an alcoholic solvent. In a linear viscoelastic region where distortion has a value of 0.1, and the storage elastic modulus G' and loss elastic modulus G'' become linear, the rust preventive coating composition precursor shows, as determined by frequency dispersion measurements at a temperature in a range of 25±1°C and at a frequency in a range of 0.1 to 100 radian/sec, the storage modulus G' in a range of 0.01 to 300 Pa and the loss modulus G'' in a range of 0.01 to 100 Pa. |
