Abstract
A method of treating paper money and the like for the purpose of identification by applying to one of the surfaces of the paper money a first treating material overcoating the first treating material with a layer of transparent material to prevent the first treating material from being removed from or obscured, and then applying a second treating material over the transparent material and the surface of the paper money where the first and second treating materials are normally invisible but rendered visible under ultra violet light. The method may also include providing means for detection of the paper money by touch, taste, smell or hearing. The invention also contemplates the article produced by the method.
Claims12
A method of treating paper money with opposed surfaces and a central portrait printed on one of the surfaces for the purpose of identifying same comprising the steps of:
- applying to that surface of the paper money opposite the surface on which the central portrait is printed a first treating material to form a source identifying code thereon where said first treating material is normally invisible but is rendered visible under ultra violet light;
- and
- applying a mixture of liquid adhesive and gritty material over a portion of the central portrait, and
- allowing the mixture to dry to form a layer defining a textured surface thereon distinguishable by feel from that of the surface of the paper money to aid in the detection of the paper money during the handling thereof by bank personnel.
A piece of paper money having opposed surfaces and a central portrait printed on one of the surfaces;
- having applied to that surface opposite said portrait a first treating material arranged to form a source identifying code thereon, said first treating material being normally invisible but becoming visible under ultraviolet light;
- and having bonded to a portion of the central portrait a cured layer comprising a mixture of adhesive and gritty material, said cured layer defining a textured surface thereon distinguishable by feel from that of the surface of the paper money.
Encoded currency for use in identifying unauthorized persons having same comprising:
- a piece of paper currency defining a pair of opposed surfaces thereon;
- a first treating material applied to portions of one of said surfaces, said first treating material being normally invisible but becoming visible while ultraviolet light is shining thereon, said first treating material arranged on said surface to form a source identifying code when visible;
- a second treating material applied to said one of said surfaces, said second treating material also normally invisible but becoming visible while ultraviolet light is shining thereon, said second treating material being capable of rubbing off of said surface onto the skin and clothing of persons handling same to assist in identifying same;
- and
- a layer of textured material applied to portions of the other of said surfaces and defining a textured roughened surface thereon distinguishable by feel from that of said surfaces of said piece of currency.
