Pigment Violet 29 (C.I. 71129) is an organic compound that is used as a pigment[1] and vat dye. Its colour is dark red purple, or bordeaux.[1][2]

Structurally, it is a derivative of perylene, although it is produced from acenaphthene. It is a less common dye compared to related derivatives such as pigment red 190 (Vat Red 29).[3][4]

Violet 29 is used in watercolors, acrylic paints, automotive paints, inks for printing and packaging, cleaning and washing agents, pharmaceuticals, solar cells, paper, sporting goods, industrial carpeting, and food packaging. Violet 29 is under risk evaluation review by the US EPA as part of the Toxic Substances Control Act.[5]
