Abstract
A security thread having an enhanced security feature is produced by forming a water-soluble ink layer on a selected portion of the surface of a transparent film; depositing a metal layer on the film surface including the water-soluble ink layer; and washing the metal deposited film with water to remove the portion of the metal layer deposited on the water-soluble ink layer.
Description
Technical field
The present invention relates to a kind of improved preparation method who is applicable to the anti-counterfeiting line of anti-counterfeiting product.
Technical background
Security document such as banknote, stock, security, check, pair (receipts) money voucher and identity card all need to protect by false proof measure, and these tickets are normally made by a kind of cheque paper that wherein embeds the Security element that fiber, bar or silk thread shape are arranged.
Such as, GB2213098 discloses a kind of film tape that is used as the part plating of anti-counterfeiting line, is a little patterns, design, mark etc. in its part that is not coated with metal, thereby forms a continuous metal planche along the length direction of film tape.
Japanese in addition publication publication number 216795/1988 teaching a kind of at the anti-counterfeiting line of transparent membrane surface plating with metal pattern.
Yet, prepare the art methods that this part as anti-counterfeiting line is coated with the film of metal and comprised complicated and dangerous etching technics.
Summary of the invention
Thereby first purpose of the present invention aims to provide a kind of improved preparation method who is suitable for the anti-counterfeiting line of anti-forge paper.
Second purpose of the present invention aims to provide a kind of anti-counterfeiting line that enhances security features that has.
The 3rd purpose of the present invention aims to provide a kind of anti-forge paper that contains this antifalse line.
According to the present invention, provide a kind of preparation to contain the method for the anti-counterfeiting line of part metal cladding, it comprises: coating one deck water-based ink layer on the selected part on a transparent membrane surface; Comprise water-based ink laminar surface deposition layer of metal layer at whole film surface, described metal is selected from the alloy of aluminium, tin, silver and cobalt and nickel; Wash this film that has deposited metal with water to remove the metal level that deposits on the water-based ink layer.
Brief description of drawings
By following description also in conjunction with the accompanying drawings, above-mentioned and other purpose of the present invention and feature can become apparent, wherein:
Fig. 1 for according to one embodiment of present invention, has shown the preparation process that partly is coated with the film of metal to Fig. 4, and the clear area of this film represents that with the form of one group of character the dyeing district is with another group character representation.
Fig. 5 is to other embodiment that Figure 8 shows that the prepared according to the methods of the invention anti-counterfeiting line.
The detailed description of invention
In implementing process of the present invention, the water-based inks water-soluble energy is imprinted on the selected part of transparent membrane substrate surface with character, pattern or digital form, forms a part of water miscible ink lay.Described base material can be selected any material well known in the art for use, such as polyester (as polyethylene terephthalate (PET)), polyvinyl chloride, polypropylene etc.Water-based inks can adopt usually used in this field any.
Next, the surface that layer of metal is deposited on whole film comprises on the surface that is printed on ink lay.The vacuum moulding machine mode that deposition can those skilled in the art be known is carried out.The representative metal that is fit to the described metal level of formation has aluminium, tin, metal alloy (as the alloy of cobalt and nickel), silver etc.The metal layer thickness scope is that 1 is to 2 μ m.
Then, wash the film that is coated with metal level with water, preferably scrub,, obtain containing the film of part metal cladding to remove the metal level that is deposited on the water-based ink layer.
In the present invention, adopt fluorescent pigment or dyestuff to make and have the anti-counterfeiting line that enhances security features, these fluorescent pigments or dyestuff make the film of part plating have two parts of metal and dyeing.In the present invention, before the printing water-based ink, fluorescent pigment or dyestuff are coated onto the selected part of film surface, in addition, if necessary, can apply the water-based ink layer so that hidden the part of dyeing.Described fluorescent pigment or dyestuff can be conventional use any in this area, and coating wherein is the method by intaglio printing preferably, with the form coating of character, pattern or numerical value.
Anti-counterfeiting line of the present invention has thickness and the width that is fit to be applied to security document, is 15-35 μ m as thickness range, and width range is 0.5-5mm.
Anti-counterfeiting line of the present invention can preferably be clipped in by between the two pieces of paper of producing respectively on the paper machine, then paper is lumped together, and has just obtained a cheque paper that is embedded with anti-counterfeiting line.Inventive embodiment
Fig. 1 for according to one embodiment of present invention, has shown the preparation process that partly is coated with the film of metal to Fig. 4, and the clear area of this film represents that with the form of one group of character the dyeing district is with another group character representation.
For Fig. 1, the method by intaglio printing is the composition of a kind of fluorescent dye or pigment, and as Lumilux CD305, CD316 or Papilion are coated on the surface of transparent polyester base material (10) by regular compartment of terrain with the form of one group of character (2).
Then, as shown in Figure 2, a kind of water-based inks is imprinted on the film, is being printed on the part of character (2) formation one deck cover film (30), also obtain the pattern (31) of another group character style simultaneously.
Then, by vacuum deposition method deposition of aluminum on the surface of the whole film of gained, obtain the layer of aluminum metal level, its thickness is 1 -2 μ m, as shown in Figure 3.
With waterside side washing brush, remove being deposited on the aluminum metal layer that covers on film (30) and the pattern (31) at last, just obtain depositing the film (1) of aluminium, it contains transparent character (5) (comparing with pattern (31)) and the print character (2) of (10) in the clear area.
Fig. 5 is to other embodiment that Figure 8 shows that the anti-counterfeiting line that is made by the inventive method.Specifically, Figure 5 shows that the anti-counterfeiting line that contains precipitated metal section alternately, it comprises rule transparent character at interval and the transparent base part that painted character is arranged.
In addition, for Fig. 6, it provides a kind of colour attaching area that different pattern is arranged, and it is evenly distributed on the anti-counterfeiting line of a kind of plating of clear area; Figure 7 shows that by on the residuite film plating metal belt of formation rule and a kind of anti-counterfeiting line of making; Figure 8 shows that a kind of anti-counterfeiting line that makes by a printing painted chain link (4) and plating chain (2) ring chain alternately on matrix film () 10.
Although invention has been described with regard to above-mentioned specific embodiment, will be appreciated that those skilled in the art can carry out various improvement and conversion to the present invention, it is also included within the scope of appended letter of authorization setting.
