Velox photographic paper was the first to require a chemical solution to develop the prints. It was invented by Leo Baekeland in 1893. He is better known for his invention in 1907 of Bakelite plastic. In 1899 Baekeland and his business partners sold their company that produced the paper to Eastman Kodak for $750,000. Velox paper was originally used to make contact prints; that is; that the negative would be placed on the paper and exposed to light. Then chemicals would be used to produce the print which was of blue-black color. Velox paper was produced until about 1963. To see directions for making Velox prints see the Velox Book (1938) on Archive.org.

Notice in the ad for Velox paper that Kodak is asking people to check the back for the name. Kodak would later use similar advertising to promote Kodak papers in the 1980s and 1990s.

The name, Velox, still exists in Rochester. Velox Street is a one block long street that runs east and west, north of Eastman Avenue (near Kodak Park).
