I must admit I don´t know anything about this process. That said, there were many different color print processes marketed to amateurs, but none of these gained much popularity, and these were mostly canceled in a couple of years. Especially when EP-2 for paper and C-41 for films became the industry standard (in the mid 1970´s), there was no actual need for these home systems, as the process was easy enough to use for amateurs too.
From historical perspective, this is interesting.
