What did I.B. stand for in I.B. Technicolor.
also...what did LPP stand for?

"Depending on the wetting properties of the fluids there are essentially two different types of displacement in two-phase flow in porous media. ..... we are considering drainage displacements where a non-wetting invading fluid displaces a wetting fluid. The opposite case, imbibition, occurs when a wetting fluid displaces a non-wetting fluid. The mechanisms of the displacements in drainage and imbibition are quite different and the two cases should not be confused. Typically, slow drainage is characterized by piston-like motion inside the pores where the invading non-wetting fluid only enters a pore if the capillary pressure is equal to or greater than the threshold pressure of that pore. The threshold pressure corresponds to the capillary pressure in the narrowest part of the pore. However, in imbibition at low injection rate the invading fluid will enter the most narrow pores before any other is considered."

For a good explanation of imbibition as it applies to motion pictures, see Marty's excellent web page: http://www.widescreenmuseum.com/oldcolor/technicolor1.htm

Don't know "LPP."

I have several 1982-1983 LPP prints that are holding up with regular use and the blacks are still black, and the colors are still vibrant.

As for Vinegar Syndrome, I have a single 35mm feature made in 1983 on tri-acetate stock that has VS in reel one only, This print sat unused in a hot warehouse for 15 years. Then I got it. The only thing that I notice on the VS reel is that there is a slight color shift on the side of the film that was up. The print was stored flat on cores.

FilmGuard took care of the smell enought so that the only time that I can smell the film is when it is being run on the mighty Holmes. R's 2-5 dont smell at all, and have no image problems.

As you know, heat and humidity and unvented storage aggravate vinegar syndrome.You can slow the progress of vinegar syndrome by storing your prints cool and dry, and using either vented storage (no sealed cans/cases) or Molecular Sieves in sealed containers:

Glad (and not surprised) to hear that Eastman LPP color prints (5384) almost 20 years old still look so good.

David Hitt: "SP" designated "short process", which was the edgeprint on 5383 using the higher temperature ECP-2 process. "LPP" was the original edgeprint used on the EASTMAN Color Print Film 5384 with improved dye stability intended for process ECP-2.
