The effect of individual paper components on the properties of an acrylate PSA adhesive after laboratory high-consistency pulping was investigated. The adhesive material was quantified by selectively dyeing the adhesive particles followed by image analysis. It was found that some of the components of copy paper have a significant effect on the size and shape of PSA particles formed during pulping. Further, some copy paper components were also found to have a significant effect on the tackiness and deposition of PSA particles after pulping. The results indicate that detackifying components prevent the agglomeration of adhesive particles and promote the dispersion in high-shear processes such as pulping.
