Well, RA4 paper also has silver halides for photo sensitivity. By
using a normal b/w developer(Dektol, etc), it should be possible to
get a silver image. The dyes will not form in this case.
But how much silver the paper has, in order to get proper density, I
am not sure. Just expose one RA4 paper and develop in Dektol and see.
On the other hand if you want b/w image(silver image) from a color
negative, then you could just use paper similar to Panalure.
