ABSTRACT:
A process for the treatment of natural discoloration in an article, particularly a vinyl chloride polymer article, by treating the surface of the article in ambient air with a first organic solution containing an organic peroxide and a first organic solvent. The invention process is particularly useful for vinyl chloride-based articles that have undergone pinking.
