I was also wondering if the resist would stand up to the etching chemicals? the main reason is, this type of emulsion is a lot cheaper and easier to get than the dedicated PCB stuff!

It was looong time that I used it to make screens for producing some
front panel foils. I may try someday :-) and feedback the findings.
