Abstract (en)
[origin: EP0761448A2] A composite structure containing a nozzle layer and an adhesive layer is provided and the adhesive layer is coated with a polymeric sacrificial layer. The coated composite structure is laser ablated to form one or more nozzles in the structure and the sacrificial layer is removed. The sacrificial layer is preferably a water soluble polymer and is most preferably polyvinyl alcohol which is removed by directing jets of water at the sacrificial layer until it is substantially removed from the adhesive layer.
