Here it is:

You do not have to get the film processed in E-4; I have found a
cross process formulation to create a colour IR negative. This
formulation applies to 35mm colour IR only, I am working on a good=20
cross process for the Aerochrome 2443 emulsion (format 9.5" x 200'). I
use it often for my own work and I have found its colour quite
satisfactory:

Kodak C-41 colour dev           12 min
wash in running water           4 min
Kodak E-6 bleach                        6 min
wash in running water           4 min
Kodak E-6 fixer                 6 min
wash in running water           4 min
Kodak C-22 hardener             6 min
wash in running water           10 min

This process temperature must be kept at 21 degrees celcius. Any
higher and the emulsion melts off. Also make sure all infrared sources
in the room are turned off; I have been caught out by this one many
times.

Have fun!
