No, It is the positive etch. It does, however have a sheet of plastic film
that you have to peel from the positive etch side of the board whereas the
other type that I had poor results with was only in a bag. Perhaps this has
something to do with the different types of positive etch boards. The
plastic stuck to the board might keep the etch resist fresh or more
protected from the environment.
