Fig. 2 Ageing curves obtained for 1–395 days-old samples from ink 1688: (A) quantities of PE recovered in natural and heated samples; (B) calculated R%; (C) RPA(PE/BA); (D) (R%* calculated from RPA(PE/BA). The inflexion intervals at which the 1st falling rate did not significantly contribute to the regression anymore are indicated with grey dotted lines.
