Abstract

Black and blue erasable marker inks were further developed in this work with a view to improving their performance over earlier attempts in the college. The inks were formulated from carbon black and copper phthalocyanine blue pigment, ethanol and propylene carbonate solvent, acrylic resin and liquid paraffin and olive oil separating agent. A Box Wilson experimental design was used for the ink formulation and the key performance properties of the inks such as erasability, writability, storage stability and darkness were evaluated with a view to selecting the best ink. It was found that the best black ink formulation, (Formulation 11), was made up of 12.5% acrylic resin, 9.5% liquid paraffin, 3.75% olive oil, 6 % carbon black, 46 % ethanol and 22.5 % propylene carbonate and its performance was identical to that of commercial black Mon Ami ink in all the properties tested except that it rated B instead of A, in erasability after 10 days and in degree of stain. The best blue ink formulation, (Formulation 4), was made up of 10% acrylic resin, 7 % liquid paraffin, 3 % olive oil, 9 % phthalocyanine blue, 50 % ethanol, and 21 % propylene carbonate and its performance was identical to that of commercial blue Mon Ami marker ink in all properties tested except that it rated B instead of A in erasability after 10 days. In odour, the formulation which was rated B was found to be even better than Mon Ami which was rated C.
