Sodium Carbonate Na2CO3.
Didn't you think about not guessing, but rather just googling
with your laminate name and "development" word?

As example, for LAMINAR 5000 dry film this would be:

-------------------
 Table III - Developing
Solution Temperature Breakpoint
Sodium carbonate
0.75%-1.0%  28-33=B0C 50-60%
Potassium carbonate 0.75%-1.0% 28-33=B0C 50-60%
REsolve 211
0.75%- 1.0% 28-33=B0C 50-60%
Developing time (sec) Laminar 5025 Laminar 5032 Laminar 5038 Laminar
5050
REsolve 211 30=B0C
Breakpoint @ 50% 37 45 55 75
(4-ft chamber)
-------------------

Good Luck.
Mike.
