A method for manufacturing a chip that includes a microchannel is described, wherein the method includes the steps of: fixing a cationic polymer having a quaternary onium group to at least one surface of each of a pair of resin substrates; and joining the resin substrates together on the surfaces on which the cationic polymer has been fixed.

The current invention utilizes an extrusion coating method as a key step in a series of multilayer construction processes to make a laminate for graphic application. The extrusion coated layer performs as a strengthening layer to provide mechanical properties for the construction, while an ink receptive coating layer delivers high quality printability performance. High gloss can be achieved through the use of a PET carrier.
