I am not sure that efke IR has an anti halation layer. I think not. Results seem to be very special, but you have to try it (so do I). My problem with Efke is their quality control: their films have scratches and pinholes. That's a pity, cause otherwise, their are pretty good as very old fashion films.
Currently there is no replacement for this film just as there never has been a replacement for HIE's sister film 2475 High Speed Recording film.Now that HIE is no longer being manufactured I am searching for a replacement that will give me similar results.This "new" film must be priced within my meager budget and fairly close to my location (eastern Canada).
Thanks
Kodak was the only folks to make the sensitizing dyes for such extreme IR response. Not sure if it's patent protected, or trade secret protected. Probably some pretty intense organic chemistry to make it.
