In this study, in order to clarify the factor of the increase in peel strength over time, we evaluated the relationship between the different surface treatments of the stainless steel(SUS304) substrates and the peel strength of the acrylic pressure sensitive adhesive(PSA), as well as the transfer component of the PSA peeled surface. As a result, the peel strength of the 2B was higher than that of the BA, and both increased with the passage of time. TOF-SIMS analysis of the PSA release surface showed that the amount of Fe+ increased with time. It was estimated that changes in the interaction between the PSA and the substrate over time affect the peel strength and transfer component.
