[Spectrum analysis of blue ball-point ink components by FTIR microsope].
The FT-IR microscope spectra of 108 kinds of blue ball-point writing inks have been analyzed in detail in this paper. According to the transmittance spectra, the composition in the ink such as the solvent, the pigment and the resin was identified. It is the base to determination of the age of ball-point writing inks nondestructively.
