I don't think there's any cause to believe this would be the case.

Now, do I have hard facts to back this up? No.. but people have been carbon printing for going on 2 centuries (minus 40 years let's say) and although there's always the possibility of new discovery, I'd say that this one has been hashed out over and over again. In the literature there is information regarding extension of the shelf-life of sensitized tissues, but nothing that could compare to diazo/azido sensitizers.
