A new instant 4X5 film that produces a superb negative, and a positive print too.
doesn't only the integrals contain titanium dioxide? however, if you haven't come across the material safety data sheets from polaroid, they might contain some useful information for you as well (they vanished from polaroids website, but can still be found here):http://www.hudsonsupply.com/type_55.htm
GeraldExcellent - thank you. The later laser patent discusses making a gradation of nanoparticles, which might occur naturally following Land's description. Rott's patent indicates that virtually any material will do - suggesting there are factors on the negs that are affected, and probably tunable, by the absorption, nucleation and ph of the receiver.
You'll note that the sixth page columns 9 and 10 are incorrectly imaged and have half the text missing - I have asked for this to be rescanned at the US Patents Office but the online copy still has this half page missing. Anyone got a paper copy that could supplement this missing info?
