Description
Technical field
The present invention relates to a kind of anti-false fiber and contain the cheque paper of this anti-false fiber, particularly a kind of have the anti-false fiber of obvious vision difference and contain the cheque paper of this anti-false fiber with viewed in reflected light and viewed in transmitted light.
Background technology
Coloured anti-false fiber has been widely used in the cheque paper field as a kind of basic papermaking anti-fake material, as bank note, marketable securities, false proof specification label or the like, but insoluble always problem is the printing color fine rule imitates its visual signature easily, more do not allow the occasion of destroying paper, counterfeit printing fine line is easy to get by under false pretences.In addition, another problem of random distribution coloured anti-false fiber on paper is to have polluted paper, and the aesthetic effect of whole layout is brought influence.
Summary of the invention
The invention provides a kind of anti-false fiber, printing fine line is difficult to imitate its visual signature in the adding thin paper, and is easy to be discerned by the public.
Another object of the present invention provides a kind of anti-false fiber, does not pollute paper during viewed in reflected light.
The object of the present invention is achieved like this:
A kind of anti-false fiber, at least be composited by cladding material 1 and inner layer material 2 two part materials, cladding material 1 is coating inner layer material 2, it is characterized in that: cladding material 1 is color A, inner layer material 2 is color B, color A and color B have tangible vision difference, and the color of described anti-false fiber when copying color when observing the described anti-false fiber be positioned at pulp layer into pulp layer back reflection light and printing opacity and observing described anti-false fiber has tangible vision difference.
Realize that the color when color when viewed in reflected light is positioned at the described anti-false fiber of pulp layer and printing opacity are observed described anti-false fiber has tangible vision difference, preferably described cladding material 1 its covering under sunshine (white light) irradiation can just cover the color B of inner layer material 2, it presents color A during the described anti-false fiber of viewed in reflected light like this, viewed in reflected light presents the synthetic color A ' of paper and color A when adding described anti-false fiber in the paper, because cladding material 1 has hidden the color of inner layer material 2 substantially, so its synthetic color A ' is near the color A of cladding material; Described inner layer material 2 is transparent colored materials, color is B, color B and color A have tangible vision difference, as transparent redness, transparent blueness, transparent green or the like, or described inner layer material 2 is a black, when viewed in transmitted light is positioned at the described anti-false fiber of paper, present the synthetic color B ' of paper, cladding material 1 and inner layer material 2, color A ' and color B ' have tangible vision difference; When cladding material was white, printing opacity was observed the color B of the synthetic color B ' of cladding material 1 and inner layer material 2 near inner layer material.
Further, the color A of described cladding material 1 is a white.
