Did Pollock Have Secret Paints?

“Jackson Pollock, famous for his dripped and poured paintings, was one of the most explosively innovative American artists of the 20th century. But was he also decades ahead of his time in terms of the paints he used? Did he have access to pigments and resins that weren’t marketed or patented until well after his death in 1956?” The question arose after several supposedly authenticated Pollocks were found to contain such pigments.
