Check background_down and background_normal properties on a Button:
http://kivy.org/docs/api-kivy.uix.button.html#kivy.uix.button.Button.background_down
You can set them to add a different background when the button is pushed
or not.
It's a border image by default, if you don't want that, set the border
property to (0, 0, 0, 0)
