Abstract: With the help of advanced modern spectroscopy analytic techniques,such as IR,ESCA and ESR,the function group composition of Korean pine wood and alkyd resin varnish was determined,also the adhesion mechanism at the interface between the wood and the varnish was mainly investi-gated.The results showed that there was no remarkable chemical reaction of function group,alkyd resin varnish between korean pine wood and alkyd resin varnish,but there was noticeable chemical reaction of free radicals,so that a certain amount of chemical bond was formed.The results support powerfully“the theory of the chemical bond at the interface between the paint molecule and painted body surface”.
