This is correct. Kodak Chemicals division, on Ridge Road in Rochester was one of the largest fine chemical manufacturers in the USA. They invented and pioneered the 'vacuum still' a method of making highly pure organic compounds and as a result became the worlds largest supplier of vitamins in the entire world. There specialties were vitamin E and vitamin A, and the work on vitamin E led directly to the original work on highly stable dyes in the 1960s, 20 years before Henry Wilhelm began his work. At that time, Kodak paper was far superior to any other paper on the market due to the use of antioxidants that were similar to Vitamin E.
Each year, they published a new huge catalog that contained many of the chemicals used in film making including developers, sensitizing dyes, and addenda.
This plant is now closed.
It was more properly called DPI or Distillation Products Industries.
