It would be a quick way to put a thin resist layer on a pcb...print it directly using the photopolymer. It resist isopropanol for sure :) , it's the only product i use for clean the prints. Now for the layer on a PCB it's not the good thing to do , the 1st layer have the elephant foot aspect (wider). With 50µ pixel size it's probably possible to rework the slicer output to make the trace thinner so it match the real trace size for the 1st layer.
