I've used a lot of Fomapan 100 and never had a halation issue.

Hi Ian,
there's no mention of a anti-halo backing for 35mm.

"The following bases are used for manufacturing the particular sorts of the film:
- 120 rollfilm - a bluish polyester base 0.1 mm thick, furnished with a matted colour backing which will decolourize during processing. The backing has anti-halation and anti-curling properties and prevents the incidence of Newton rings during
enlarging.
- 35 mm film - a gray or gray-blue cellulose triacetate base 0.125 mm thick,
- sheet film - a clear polyester base 0.175 mm thick furnished with a matted colour backing which will decolourize during processing. The backing has anti-halation and anti-curling properties and prevents the incidence of Newton rings during enlarging.
