Some problems of etching my first PCB

I have printed the layout with an inkjet printer onto film and the result looks pretty good. I have a UV exposure unit and tried a wide range of exposure times- It seems to need 20 mins in order to yield what looks like a good result in developing after a couple of minutes. Etching starts well, but I always end of with some of the tracks dissolving away- the resist seems to flake away exposing the copper underneath.

We need to know details about your type of sensitized board and developer.

The time you used for UV exposure seems too long. I use about 2min30s to 2min40s for my boards and that is with a similar UV lightbox from RS.
