Abstract: A black pigment composition is provided to realize at least the same level of physical properties and color maintenance as carbon black when applied to coating natural leather by reutilizing waste leather sludge. A black pigment composition comprises: (i) 35-50 wt% of carbonized leather waste sludge having an average diameter of 1-5 micrometers; (ii) 10-20 wt% of a dispersant; (iii) 4-10 wt% of casein; (iv) 0.01-0.5 wt% of an antibacterial agent; and (v) 20-50.99 wt% of a solvent. The carbonized leather waste sludge is obtained by carbonizing leather waste sludge at 400-600 deg.C. The leather waste sludge comprises 50-75 wt% of water, 20-40 wt% of combustible dust and 5-30 wt% of ash.
