What is the photoresist for the formula of etching Elgiloy?

+++++

We need a smooth through-etching of Elgiloy. The thickness is 0.15 to 0.25 mm. We find "How to etch Elgiloy (metal)?" in the following web:

http://www.finishing.com/119/36.shtml

15 mL HCl + 10 mL HNO3 + 10 mL acetic acid. Mix fresh. Swab onto the surface (Rather than immerse) for up to 4 minutes.

But it damages the photoresist. What type of photoresist that I should use?
