PHOTO DEFINABLE POLYIMIDE FILM USED AS AN EMBOSSING SURFACE.

摘要

An embossing surface (4) and a method for creating that surface (4) is provided by a polyimide material (1) which has photodefinable characteristics. One benefit is that the embossing surfaces (4) do not have to be made by data transfer from the photodefinable surface. The polyimide material is cured by heating (5,7) to a predetermined hardness appropriate for the surfaces to be embossed.
