New constructions of multilayer optical films, laminates thereof, and
cards incorporating same are disclosed. In a card, the multilayer optical
film can be sandwiched between relatively thick polymer layers using
adhesive layers that are at least 0.5 mils thick but that may
collectively account for no more than 3 mils of thickness. The cards can
if desired be highly transmissive in the visible yet highly opaque in
portions of the infrared. The resulting cards can have reduced angel hair
formation during card stamping, increased resistance to delamination, and
reduced haze.
