Apologies for some reason since I cut & pasted the table the line for time/temperature/formula becomes corrupted, this should be OK now

Early Telcolor films were designed to gain a silvermask after processing. This was achieved by propriatory processing done in exclusive laboratories.
Alternatively one could process it the Agfacolor-way as indicated above.

Early Agfacolor (pre CN14/CN17) was very different as well. I have much older formuale somewhere.
