Formulation of Paints Using Azo Pyridone Pigments and Alkyd (Soya Beans Oil), Characterisation and Their Application on Leather

The use of locally available raw materials in theformulation of paint is of paramount importance as it providesjob opportunity for poor local people, produce ecofriendly andbiodegradable products as well as substantiates the aspect ofmodern biotechnology in developing countries. In thisresearch,Paints were formulated using azopyridone complexesand soya alkyd derived fromesterification of soya oil with maleicanhydride and glycerol. The formulations were applied onleather using hand brush, and the samples produced weresubsequently, subjected to physical characterisation such asdensity, viscosity, solubility, surface drying times, pH and lightfastness and also compared with the commercial paint. The pHand the fastness property of the coatings were found to be 8 and6-7, respectively, which is very good
