Hi Rob ... The earliest reference to the use of an antihalation layer that I could find goes back to 1935 for Kodak film. I don't know when it became "commonplace" for B&W emulsions, but I am curious about it.
"In 1935 Kodak announced Kodachrome, the first truly successful color process, developed largely by Drs. Leopold Godowsky and Leopold Mannes, both musicians and scientists. Raw stock had blue, green and red layers on a film support and then an antihalation layer to prevent glow around highlights." Rob Studdert wrote: > What about the effect of the anti-halation layer?
