Abstract
Security paper, security documents made from the security paper, and processes for making the security paper, are provided. A filament is bonded and embedded into paper which has previously been manufactured. The filament is bonded to the paper by an adhesive, or by heat and pressure. The filament is embedded into the paper by pressure applied by rolls. The filament may be imprinted with printed matter for visual confirmation of document authenticity. The filament may include any combination of security features, such as reflective filaments, fluorescent filaments, and high tensile strength filaments.
