1. A process for laser scribing a pattern in a planar laminate having at least one overlying layer and at least one underlying layer, comprising:

  • applying a focused laser beam to an area of the pattern to be ablated on the overlying layer side of the laminate, said laser beam having a wavelength which is substantially unabsorbed by the overlaying layer but which is absorbed by the underlying layer, such that at least a portion of the underlying layer is directly ablated and the overlying layer is indirectly ablated throughout its thickness in the area of the pattern to be ablated.
