Sažetak
This paper presents the examination of effects of amphoteric surface active chemical cocamidopropyl betaine (CAPB) on the optical properties of various office paper brands (Navigator, Fabriano, Rcopy, Pioneer, IQ and Plano Premium). In order to analyse the effects of cocamidopropyl betaine on the office papers’ optical stability, two types of sample treatments were performed: Soaking and disintegration. Likewise, for the purpose of better optical stability evaluation, the same analysis was done with distilled water. All paper samples were exposed before and after treatment to visible and ultraviolet electromagnetic radiation. The influence of ultraviolet radiation on all treated office papers was examined through reflectance spectra using X-rite Spectrophotometer. The gained results showed that cocamidopropyl betaine affected optical properties of all analysed office papers, independently of the type of treatment, compared to non-treated originals. It was evident that the degree of surfactant solution effect on the optical stability was conditioned by paper composition.
