ABSTRACT:
This invention relates to a biaxially or multi-axially oriented, heat set film, which has on its surface numerous unevenesses, which comprise indentations around a protrusion. The protrusions comprise crosslinked or hardened organic particles having an average particle size of from 0.01 to 5.0 microns and having a narrow particle size distribution. The film surface has a mean surface roughness value Ra of from 0.005 to 0.10 micron.
