Kerik, I found several references about gelatin inhibiting Pt right now I can only find this historical one....

"We find evidence from an early stage (1880) of Willis's awareness that platinotype chemistry is inhibited by gelatin. He therefore avoided it as a sizing agent for his papers..."

There was also a more recent reference that actually explained what was happening in terms of the chemical process and as I recall the Pt was more inhibited than the Pd..... I will try to find that link tonight.

I do not know the name of the paper..... I found a simple way to strip the emulsion from PX 3001 (yes I can hear you all groaning in disgust... but the paper surface is gorgeous and the paper is strong).... I think that if I can find the right resizing agent it will be a viable paper for me... sorry to disappoint.
