Some aspects of the adhesion of paint to wood were studied by the selection of a well characterized substance to take the place of wood, in this case, cellulose and a well‐known polymer, an epoxy system, which is frequently used as the polymeric constituent of a modern paint. Attenuated total reflectance (ATR) infrared spectra of some wood surfaces from which the correlation with the cellulose ATR spectra can be seen, have been reported [1]. The synthetic spectrum of cured epoxy system and cellulose was prepared by placing a cast and cured epoxy system sheet on one side of a KRS5 internal reflection plate and compressed, reconstituted cellulose on the other side. This spectrum was compared with that of a cast and cured cellulose‐epoxy system mixture. The OH‐stretching band (3350 cm −1 ) and the C‐O stretching bands (1050‐1000 cm −1 ) of the cellulose were greatly decreased in intensity, while the epoxy band (915 cm −1 ) and the band at 1160 cm −1 had virtually disappeared. A total frequency assignment of both the epoxy system and the cellulose are presented. The adhesion at the cellulose‐epoxy system interface is discussed with respect to the chemical changes inferred from the above‐mentioned spectra.
