Abstract
A lottery ticket, for example of the "instant" scratch-off kind, comprises a non-opaque base paper and a coating layer or layers positioned between the base paper and win-or-lose indicia carried by the ticket. The coating is not self-supporting, so that it is not itself susceptible to fraudulent delamination, and is opaque with respect to transmitted light. Thus even if the base paper is delaminated, the win-or-lose indicia are still not discernible on viewing the ticket against a high intensity light source, since the opaque coating is still between the indicia and the light source. The desired opacity of the coating is achieved by the use of opaque pigments such as carbon black or aluminium powder or flake. The opaque coating can carry a light-coloured topcoat for enhanced printability, or a lustrous topcoat giving an attractive decorative effect.
Description
The present invention relates to lottery ticket and the paper that is used to produce this lottery ticket.Said lottery ticket is typical what is called " immediately " type, and when the buyer removes its cover layer, whether when being typically a kind of scrape layer, then demonstrating this lottery ticket of following decision is the mark of winning ticket.
Basic demand for this lottery ticket is to guarantee to prevent fraud.Therefore, it must make anyone can not conclude under its tectal situation that a certain specific lottery ticket is to win ticket or defeated ticket not removing, and removes cover layer, and then lottery ticket can not re-use.Equally, this lottery ticket must guarantee false proof, promptly prevent the unauthorized production of complete lottery ticket, prevent to alter, for example the mark of winning is transferred on another lottery ticket from one with the lottery ticket of crossing, thus the latter can be on the mark that print overprint and make it to appear as original lottery ticket and make it rewin the second time suitably.
Up to the present, obtained approval on the wide range of commercial based on the lottery ticket of aluminium foil and paper laminate.Aluminium foil is lighttight fully to transmitted ray, and this character is under lottery ticket places high light the time, and preventing of following win or defeated marking visibility is necessary.Many paper used in everyday or other goods are opaque to reverberation just, but are not to transmitted ray, and this point must correctly be differentiated.This point is under intense light source, as under xenon lamp or the high intensity tungsten halogen spot so especially.
Yet, use the aluminium foil and paper laminate to have a lot of shortcomings.The first, this paper tinsel thereby has the possibility of taking off thin layer from paper from carrying (self-supporting).Thereby the lottery ticket that uses this paper tinsel is easy to be altered.The second, aluminium foil and base paper are easy to obtain, thereby the risk of forging is very high.Although this risk can be by using false proof chemicals (security chemicals) or other false proof will usually reductions on these paper, it can not be eliminated fully.The 3rd, before lottery ticket is promptly brushed or in printing process, aluminium foil is very easy to because of accidental bending or folding and destroyed, so loss is very high.The 4th, use aluminium foil meaning to produce in the lottery ticket production process waste material or lottery ticket to use the back because can not reslurry and make it can not be recovered utilization.
European Patent Application No. 428489A proposes by using a kind of lottery ticket base paper to avoid these defectives, and this base paper obtains by a kind of dark pigment such as carbon black are added on the base paper the required opaqueness of transmitted light.Because this dark paper not exclusively is fit to printing, so with pigment/filler/base-material (binder) composition of the light colour of the conventional kind of two a kind of suitable printings of surface-coated of this paper.
This lottery ticket paper has been avoided many defectives of above-mentioned aluminium foil and paper laminate, but it might be altered by delamination between the thickness of lottery ticket paper.Because this light colour coat self is not lighttight for transmitted light, and can not provide enough opaquenesses because the fibrage that stays after the delamination is too thin, so can demonstrate the mark of winning or failing by under high-intensity light source, observing the delamination lottery ticket, thereby the win ticket just can be recognized.These can be reconfigured and go to claim bonus then.Similarly, the win ticket of using also can be by delamination carefully, and the mark that will win is transferred on the appropriate section of defeated ticket of a delamination.
Also propose that by the people lottery ticket comprises one by at least two laminate of forming from bearing bed, this laminate is peeled away the back and is shown the mark of winning or failing, and for example sees U.S. Patent number 4120445.This win or defeated mark can be positioned at wherein on one deck, maybe can be located at by on the insert in this two-layer folder bag that forms (pouch).The shortcoming of this lottery ticket is to need additional processing step in their production process, that is, not only must production can win or the coating substrate of defeated mark for applying, and must carry out a kind of manufacturing and transition operation is produced this required laminate or folder bag structure.
The lottery ticket that the object of the present invention is to provide the defective of above-mentioned lottery ticket structure to be overcome or to become so not serious.
The invention provides a kind of multilayer lottery ticket that has win or defeated mark, it comprises:
A) constitute lottery ticket separately from bearing bed and not to the lighttight paper substrates layer of transmitted light;
B) coating layer between described basalis and win or defeated mark or multi-layer coated layer, this coating layer is lighttight for transmitted light basically, thereby prevents from this win or fail to observe under the background that is marked at high-intensity light source to become as seen; And
C) a removable cover layer on described win or defeated mark, this cover layer is opaque for reverberation, thereby can prevent this cover layer be removed before described win or defeated mark be visible.
This produce opaqueness coating layer can based on, for example, Opacifying pigment, as carbon black, graphite and/or a kind of opaque glossy pigment are as aluminium powder or flake aluminum and a suitable base-material or a base material mixture.This base-material is typically a kind of latex, and for example, styrene-butadiene latexes randomly is the mixture with any latex, for example polyvinyl ester latex.The high light absorbing dye for example, is deceived or the navy blue dyestuff, can be used to strengthen the opaqueness of coating layer.Though these can provide all desired opaquenesses in principle, find usually that when practical application these dyestuffs by itself, that is, do not use the pigment of light-proofness that desired light tight degree can not be provided.
This coating layer that gives opaqueness can be coated with by the conventional coating technique in the paper industry, for example, and the air knife blade coating, metering roll (metering roll) is coated with method, Meyer rod (Meyer bar) is coated with method, scraper plate rubbing method, and excellent scraper plate (rod blade) rubbing method.Or alternatively, this coating layer if be fit to, can be coated with by means of printing machine.
This paper substrates layer can be conventional white or chromatics paper.It should have enough deflections (stiffness) and can be processed, is typically to have 200 to 220g/m
2Every square of Mick number of grade.
Usually need be when containing carbon black or other dark pigments or dark dye in the coating layer than the top coat (topcoat) of the pigment/binder of light colour in order to obtain printing writing with enough definition.Inorganic pigment such as calcium carbonate, kaolin or titanium dioxide, or organic papery coating pigment can be used for top coat.Base-material is typically a kind of latex, for example styrene-butadiene latexes.Yet in principle, top coat is not absolutely necessary, because can use white or silver color or other contrastive colours ink printings on black or dark coating layer.At light tight coating layer is under the glossiness situation, for example aluminium powder or flake aluminum, be follow-up print distinctness, top coat is unnecessary, because this coating layer also has the outward appearance (this glossiness coating layer is the dyestuff of available routine if desired, toner or other colouring agents make it is painted) of shallow relatively gloss except it is light tight.Top coat, for example transparent top coat certainly uses for other reasons, and for example, thereby the cohesive force that improves pigment coating reduces the dry linting (dusting) in printing process or peels off (pick-off).
Though the opaqueness that flake aluminum can provide needs high coating weight, 25g/m at least
2, just can provide absolute unglazed transmission, be essential and do like this.This is expensive, and also is difficult to be applied to the single application operation.Thereby, when using flake aluminum coating, the preferred priming coat (undercoat) that uses dark color.This priming coat can contain dark dye or dark pigment, as carbon black or graphite.The use of this priming coat can be reduced to the coated weight of required flake aluminum one more easy-operating amount, promptly about 15g/m
2Or alternatively in the single coating layer, adopt the mixture of aluminium powder or flake aluminum and dark pigment.
If desired, top coat can provide distinguished ornamental outward appearance, in fact is not metal by using for example, and opposite with metallic pigments, can make the penetrating iris of transmitted light, pearly-lustre look or other glossiness pigment.This pigment based on mica is normally by having applied metal oxide, and for example the thin splitting of titanium dioxide or iron oxide is formed.Can obtain various color harmony coloring effects, the pearly-lustre pool in silver-colored, red, yellow, blue, green or other tones for example, or the metallic luster in silver, gold, burnish gold, copper or bronze colour for example.These pigment can be purchased, for example from the E.Merck of Darmstadt company of Germany or their agent in Europe with trade mark " Iriodin ", buy with " Afflair " in the U.S. and Canada.
This lottery ticket paper can be printed with the mode of routine becomes lottery ticket.Be typically to be included in to print in the first impression operation and win or defeated mark and any essential identification information, some bar codes for example, then, thus opaque this win or the visible cover layer of defeated mark avoided of a pair of reverberation of overprint again.It is one that this cover layer can melt ornamental and informational material, lottery ticket title for example, and promoter's explanation, or advertisement, perhaps this ornamental and informational material can further printed in the printing operation.Usually print this win or defeated mark with uv curing ink, for example adopt the printing ink ink-jet printer.Printing has provided the printing of very low section like this, and this printing can not be detected by sense of touch through overprint.This cover layer that can be scraped off can be with for example printing by rotary screen printing or the printing of elasticity version.The suitable prescription of this coating that scrapes off had discussion in " The Printing Ink Manual " [publishing (the 4th edition 1988,509 and 510 pages) by Van Nostrand Reinhold (International) Co.Ltd with Society ofBritish Printing Ink Manufacturers associating].Be typically, comprise the aluminium powder that spreadability (opaqueness) is provided in this prescription, the what is called that can scrape off characteristic " easily curved (pliable) " resin is provided, and, the organic pigment of painted or decorative effect selectively is provided.
The reverse side of this paper substrates, promptly having the opposed surface that gives the opaqueness coating can be not coated, because opposite with loaded sheet in being disclosed in european patent application 428489A, it is easy to print by routine techniques.
Lottery ticket paper of the present invention has its advantage, though promptly it can be by delamination on the thickness of paper in principle, win in the time of under it is exposed on high light on the lottery ticket or defeated mark still can not be seen.This is that what opaqueness was provided is coating layer rather than base paper because opposite with the proposal of european patent application 428489A.Thereby, after the delamination in the minimizing of mark and the base paper that stays always exist light non-transmittable layers between the part of thickness.This coating layer is actually granular substance, rather than the layer of carrying certainly, thereby owing to can not lean on self and intactly existence without any the bearing bed of fiber, the trial of altering with coating layer under any circumstance all will be easy to penetrate.
Because paper of the present invention do not use the paper tinsel layer, waste material can reslurry and thereby compare with the paper tinsel/ply of paper compressing tablet that up to the present generally uses, reclaim and no longer be a problem.
This paper substrates and/or the coating layer on it can add false proof and/or ornamental feature in addition, for example be mingled with by dyestuff, color generates or the change chemicals, painted and/or " sightless " planchet (planchettes), the field trash that glitters (sparkling inclusion), instant checking (instant verification) chemicals is used to the sensitization chemicals of finding that fraudulent is altered, metal or iris pigment etc.All these itself all are known, so do not need to describe further.Paper substrates is also can be in secret paper conventional to be used, and other comprises Silurian fiber (Silurian fibre) or secret line, fibril or fillet.
