Medium for laser printing including optical special effect flakes

摘要

A laser toner includes optical effect taggent flakes or other structures in a binder suitable for binding particles to a substrate. Preferably the optical effect taggent structures have a substantially same shape or same indicia within the binder sized to be suitable for laser printing. After printing the flakes or structures become bonded to the substrate they are printed upon and are discernable by viewing with magnification.
