Abstract
A soil and/or moisture resistant secure document and a method for producing such a secure document, are provided. The inventive method preferably employs a size press or other similar device to force a soil and/or moisture resistant formulation into the pores of the substrate and to remove excess formulation from opposing surfaces thereof. Soil and/or moisture resistant formulations when applied this way instead of by way of standard coating techniques do not obscure optically variable effects generated by non-porous OVDs that may be employed on or within these secure documents. In addition, thin layers of fibers (e.g., papermaking fibers) overlying and thus embedding portions of security devices in windowed secure documents that have been rendered soil and/or moisture resistant in accordance with this invention demonstrate increased durability.
