Homebrew PCBs

Hi all!! I'm trying to make some pcb's using the tonner transfer 
method. After ironing for about 6 minutes, the paper isn't completely 
glued on the board. The board was cleaned with acetone so I guess that 
the paper I'm using isn't appropriate.
I know Staples paper work fine but I live in France and there isn't 
Staples products here :-((. 
Does anybody knows what paper commercialized in France works for this 
method? Or I must iron more until the paper completely melts on the 
board?

THANKS!!!!!
