Description
Technical field
The present invention relates to be used to produce the cheque paper of value document, value document such as banknote, passport, identification document etc.This cheque paper has flat substrate, and this substrate is provided with the soiling protective layer that is used for life-saving and is suitable for circulation at least in part.The invention still further relates to value document with this cheque paper and the method for producing this cheque paper.
Background technology
Such as banknote, stock, security, certificate and rebate coupon, check, high-quality admission ticket valency and anti-counterfeit printed arranged, also have other that file such as passport or other identification documents one class of forging risk is arranged, usually have elaborate printed images, to increase the ability of its anti-counterfeiting.At least use such as the technical sophistication of intaglio printing one classes to some picture element and be not the printing process that everyone can touch.
In addition, the anti-counterfeit printed common so-called Security element that has been equipped with, this class Security element are difficult to copy, and can make the layman check the authenticity of this printed matter or file.This Security element can be the opened window safety line that see in can be on the valency paper surface is arranged certain zone; The paper tinsel that applies with hologram transparent or the metallization relief; Blind blocking; What is called " sub-image " by the printing technology that different information can be provided at different viewing angles or printing and the production of embossing technology; Pigment that comprises optically-variable and traces according to the different generation of viewing angle different color effect; Or comprise the have metallic luster trace of printing ink of metal effect of (for example gold, silver or bronze tone).
An important component part such as the value document of banknote one class is flat substrate, and it preferably mainly is made of cotton paper, and its typical tactile sensation is subjected to the influence of the one or both sides calendering in the steel plate engraving process.The sense of touch characteristics of banknote mainly show as its sensation and flexible rigidity, and a kind of distinctive sound is arranged when distortion and crumple in addition.
Known provide have a soiling protective layer the valency paper arranged, with life-saving be suitable for circulation.For example, document EP 0 256 170 B2 propose to make the banknote of printing have protective layer, and this protective layer comprises that cellulose esters or major part contain cellulose esters and smaller portions contain micronized wax, and this protective layer is laid on the whole banknote.This micronized wax is by rubbing or mixing with oil, ink binder or its mixture and disperseed.The file that just has been printed with protective layer can pile up without difficulty, does not have black ink on a piece of paper following paper of making dirty.
Document WO 00/00697 discloses a kind of cheque paper that is used for banknote, and this cheque paper has nonpolluting coating, this paper and the not paper comparison of coating, although coating is arranged, its representative property (for example impressionability, sound and color) major part remains unchanged.Only comprise adhesive and the coating composition of filler-free puts on and has high surface area or owing to porous makes on the big bank-note paper of surface roughness.On the one hand, this composition is applied for a bed thickness, makes the possibility of smooth surface and dirt deposition little; On the other hand, this coating is very thin, can not damage other described character of this paper.
Known protective layer generally is that abrasion protection is not strong especially.Traditional protective layer that comprises water-based paints can not satisfy desired profile fully.For example, soil resistance is fine and bond quality is very high to stoping the liquid infiltration unfavorable, and vice versa.Therefore, have only the second kind of composition that adds the crosslinking agent form, water-based paints could satisfy the high request of the protective layer in anti-counterfeit printing, particularly the banknote printing at present.Because the reactivity of this crosslinking agent own is very strong, so operating personnel must incur danger and should take suitable safeguard measure.
Summary of the invention
The present invention is based on the problems referred to above proposition, its objective is the production method that a kind of cheque paper is provided and can avoids the shortcoming of prior art.Specifically, this cheque paper is owing to good antifouling character, and its life-span is long and big to the resistance of liquid infiltration.
This problem is solved by the cheque paper of the feature with independent claims.The production method of value document and cheque paper is the theme of claim arranged side by side.Further expansion of the present invention is the theme of dependent claims.
According to the present invention, this protective layer comprises at least two enamelled coatings: first time top coat layer, form by being applied to on-chip physical dryness enamelled coating, and this first time top coat layer contacts and seals its hole with following substrate; Top coat layer on second, the protection substrate is not influenced by physics and chemical factor, and the not influence of liquid body infiltration and ink penetration of good protection.
The present invention is based on this discovery, if promptly the recess of substrate, non-uniform areas and hole are in advance by the sealing of the enamelled coating of physical dryness, then the beneficial property of radiation curing lacquer can be used for cheque paper.The shortcoming that radiation curing lacquer and particularly UV curing are coated with lacquer (being called " UV lacquer " later on) is: different according to quality, radiant power, initiator system and the monomer system of substrate, behind radiation curing, in this substrate recess and hole, remaining monomer and freely photoinitiators be still the very strong composition of reaction as a rule.
When UV lacquer penetrated in the paper fibre composites of cheque paper for example, this problem was increasingly sharpened.UV coats with lacquer polymerization no longer fully.Find now; if use the comprehensive coating that comprises at least two enamelled coatings; wherein descend top coat layer to contact and seal its hole with substrate, last top coat layer is not influenced by physics and chemical factor for this substrate of protection layer, then cheque paper can utilize the good reliable character of ultraviolet ray lacquer fully.
The flat substrate of this cheque paper is formed by cotton paper printing or printing.Such as cotton paper porosity height, the rough surface of the false proof and value document of banknote one class, have micro-projection and pit; In these projectioies and pit, when not using of the present invention time top coat layer, the residual monomer of the enamelled coating of radiation curing and photoinitiators can deposit.
This time top coat layer is formed by water base dispersion enamelled coating.Advantageously, it can be applied on the substrate by bed thickness, makes it form smooth pantostrat on this substrate.This time top coat layer is preferably flexible, to avoid owing to mechanical movement or the expansion of fiber absorbs moisture and form crackle in enamelled coating.Such advantage is the typical haptic that can keep banknote more longways, i.e. flexible rigidity under stress and sound.Particularly under extreme climate and mechanical stress effect, has positive role.Elastomeric paint preferably includes and makes this coat with lacquer resilient polyurethane system.These are the aqueous based dispersions of aliphatic poly ester polyurethane or styrene-propene acids polyurethane specifically.Obviously, in other factors, required coating amount is decided by used lacquer, used substrate material and roughness and pore size and porosity factor.
Should go up top coat layer and be preferably enamelled coating radiation curing and/or physical dryness, and preferably include silicones and/or wax, to improve antifouling character.Specifically, the enamelled coating of this radiation curing is ultraviolet-crosslinkable enamelled coating (being called " UV lacquer " later on).The high physics of this lacquer and chemoresistance can improve the quality and the adaptability of the profile that requires.Higher physical resistance can make the abrasion resistance of this cheque paper good and prolong its life-span.Higher chemoresistance also can make this protective layer become the shielding of an anti-steam long-term stability, effective and liquid (for example printing ink).
In addition, use UV lacquer also to provide many possibilities for the sense of touch that influences cheque paper (concrete be banknote) selectively.Regulate topmost fragility, gloss and the slickness parameter of protective layer, can directly influence the tactile properties, particularly its flexible rigidity, slickness and sound of this coated paper in every way.Advantageously, select the composition of this UV enamelled coating at fragility and surface tension especially, so that obtain the predetermined sense of touch of this cheque paper, particularly predetermined slickness, flexible rigidity and/or sound.
For the enamelled coating of radiation curing, except the crosslinked UV of atomic group coats with lacquer, can also use cationic crosslinked lacquer system.
Another kind of scheme is that this physical dryness layer comprises aqueous based dispersions as last top coat layer, does not preferably have the polyurethane composition, for example styrene-based-acrylic acid.
Equally, top coat layer can comprise mixed paint on this, and this mixed paint comprises the physical dryness composition of painting branch one class such as water base dispersion, and comprises radiation curing and paint branch.In this mixed paint dry run, at first utilize the method for physics, for example remove water constituent by heating, utilize for example ultraviolet ray irradiation to solidify this radiation curing then and paint branch.Suitable mixed paint is based on the moisture dispersion of aliphatic urethane acrylate and suitable monomer or reacting oligomer, particularly has the acrylate (acrylate with photoinitiator) of photoinitiators.
In a preferred embodiment, directly should go up top coat layer is applied to down on the top coat layer.Another kind of scheme is on this and between the following top coat layer another enamelled coating that comprises aqueous based dispersions to be set.
The cementing property of the enamelled coating of protective layer advantageously can be coordinated mutually, to form the bonding of good endurance.Specifically, in the time directly will going up top coat layer and be applied to down on the top coat layer, select the composition of top coat layer down, with the bonding of the optimum of the radiation curing lacquer that guarantees to be applied with subsequently.In a preferred embodiment, can make the wettability optimum of this time top coat layer by the glass transition temperature that reduces the lacquer system.This can make the bigger and promotion improvement bonding of cohesive force.
