Valery,
I tried the film. I started with an exposure of 400 uJ for all three wavelengths . I got nothing. I kept increasing the exposure. At about 5 mJ, I got a dim image. All three wavelengths were present and about equal, but very dim. I then increased the exposure to 7 mJ, and got nothing again. Clearly, then, 7 mJ was overexposed. So, it looks like 5 mJ was the ideal exposure. But, if such a high exposure was necessary to get anything at all, I'm assuming that the grain size is very small. In this case, it may be necessary to use a physical developer. I used CWC2 and PBU. You mention GP-2 and SM-6, which, I believe, are physical developers.
I don't have the chemicals to make a physical developer, but I'll keep on testing.
