Kodak TMX, Special Coating Blocking UV Light

[lensmagic]

In the May/June 2008 issue of View Camera Magazine, Sandy King, in an excellent article comparing T-Max 100 and T-Max 400 films, found among other things that T-Max 100 has a special coating that blocks a huge amount of the available UV light, making TMX virtually useless for printing with UV sensitive processes. My question is: does this coating block UV light when the film is initially exposed, or just when a print is being made from a TMX negative? In other words, if I want to photograph a scene for which I would normally affix a UV filter, can I dispense with the UV filter if I use TMX film?

-) A UV-blocking coating will block UV anytime. (Of course it needs to be be in the optical path. A UV absorber in the base won't effect the emulsion...)

-) I only know of two methods of installing a UV-blocker in processing: the lacquering of a print with UV-blocking varnish and the soaking of a print with brightener (though that is actually inot intended as UV-blocker).

I believe the coating is on the base side, so it effects only when you are printing the processed negitive.
