Polyurethane fibre has been dyed with a methanolic extract from the leaves of Ocimum sanctum containing ursolic acid as the major colourant with or without various metallic salts and different mordanting techniques. The improvement in depth of colour without altering the tone is observed. The colour of the samples has been evaluated on computer colour matching system in terms of K/S and L* a* b* colour coordinates. The dyeings show moderate to good fastness to washing, light and rubbing.
