IDK. I've never tested it. And, if it fails, you have no way to tell if your chlorophyll was good and didn't work or bad from the start. Besides, for a reliable test you need a spectrosensitometer to test the coating just as I do. Or you need to give it pure red light exposures to test it.
In addition, chlorophyll is not a "true" red sensitizer. A true red sensitizer is cyan in color and not chlorophyll green. This is just an approximation.
