Dissolve polygon and retain attribute fields

Hello,

I have merged a number of layers that contain polygons together.

These are from tiles that are adjacent to each other so where two polygons are next to each other there is a line where they both join.

I can dissolve the two polygons into one using the 'Dissolve' tool. However when I do this I lose the attribute information associated with the polygons.

Is there a way around this to combine the polygons without loosing attribute information?
