Abstract

Abstract Fourier transform infrared photoacoustic spectroscopy(FTIR-PAS) was applied to the measurement of photochemical changes of presensitized offset printing plates. FTIR-PAS was found to be a useful method for obtaining direct information on structural changes of photosensitive resins on roughened metal surface.
