Fuji 100B negative?

I remember Polaroid B/W where you had a positive print on paper and negative film that could be used on an enlarger. As Polaroid has stopped producing films, I wonder if Fuji FP 100B or 3000B also have a negative that can be used to reproduce the foto? I have been looking around on Internet but can not seem to find a decisive answer. Maybe someone can confirm if this is possible or not. If not, it is no use buying a MF camera with polaroid back for me.

Thanks

No, you can't. I use FP3000B, and if you have a negative, it's on a opaque sheet, so you can't reproduce it. The only way is to scan the positive...

Thank you, Aurelien, for the very fast response. I will stick to film then and wait for the result after develloping.
