Abstract: In the art of treating plastic surfaces to improve the adhesion of paints or metals thereto wherein the surface is treated with a strong mineral acid solution containing hexavalent chromium, the adhesion is improved by adding to the acid solution from 0.1 to 6 percent by volume of a petroleum fraction boiling between 80* C. and 240* C. which is rich in branched chain aliphatic hydrocarbons and alicyclic hydrocarbons, olefins containing a neopentyl group, or carboxylic acids containing a neopentyl group.
