Abstract
The utility model relates to a label against counterfeit, which is composed of a basal layer and a paint layer containing hot color pigment. The surface of the paint layer can also be added with at least one layer of cover layer, such as a plastic thin film and an aluminum foil. The label can make reversible color changing in high-temperature, and the purpose of identifying the true-false of products can be achieved when the label is printed and pasted on the products or product packages.
Description
The utility model relates to a kind of anti-fake mark with layer structure, and particularly a kind of have anti-fake mark or a label that contains the pigment coated structure of thermocolour.
In the quite a while of economic development, always there is fakement to flood market, illegal people profits from, and has seriously destroyed the reputation of its original product, and brings greatest loss to the consumer.Like this, the various false proof means of the numerous and confused employing of each tame manufacturer.
At present, the false proof various holographic labels or labels that adopt holographic compression moulding to make of general commercially available prod because the production equipment cost of this mark is not high, have the producer of economic capability constantly to increase more, problem of management makes the effect of this anti-fake mark be affected day by day in addition.
A kind of anti-personation label of China's utility model patent (CN91218713.1) record, it by take the photograph by the black and white film of specific identifier pattern be doped with the adhesive layer of temperature sensitive liquid crystal material and dark-coloured coating is compound forms, this label can touch intensification or make its cooling make the liquid crystal material variable color by hand, demonstrate specific identification pattern whereby, thereby play anti-fake effect.But, this sign manufacturing trouble, cost is higher relatively.
For overcoming above-mentioned the deficiencies in the prior art part, the purpose of this utility model is to provide a kind of novel anti-fake mark with layer structure, it is pigment coated to contain thermocolour in the employing of the centre of this mark, the reversibility variable color at high temperature takes place in this layer, anyone can both differentiate voluntarily to the product that adopts this anti-fake mark, to reach its false proof purpose.
The purpose of this utility model is achieved through the following technical solutions: it comprises a thin film based bottom, the topped dope layer that contains thermocolour pigment on the basalis surface, and wherein said thin film based bottom is plastic sheeting, aluminium foil or viscose paper.The utility model also can be on the described dope layer that contains thermocolour pigment the topped overcoat of one deck at least.This overcoat is plastic sheeting or aluminium foil or polyamide film.
The used thermocolour pigment of the utility model is also referred to as temperature sensitive pigment, thermosensitive pigment may or thermochromic pigment, and it when being heated change color can take place, and can return to its original color after the cooling again.Generally, thermocolour pigment divides two kinds of organic or inorganics.The variable color of organic thermocolour pigment is because heat moves or two kinds of steric configurations the balance that molecular structure has taken place between electronq donor and the electron acceptor, the change of two kinds of crystal structures, for example, dibutyl tin is two, the variable color of organic pigments such as crystal violet lactone is to be heated the crystalline phase variation takes place, and dentate geometric configuration or coordination number change and produce.And CoCl

2All can make inorganic thermocolour pigment with the hexamethylenetetramine complexing.
Reversible variation is carried out mutually to green, orange, black, red, blue, purple in red in the form and aspect of inorganic thermocolour pigment, yellow, orange, peach red, green, blue etc.This pigment can with other pigment look of abandoning, other secondary color or secondary color and do not influence its color changeable effect of furnishing.
The utility model preferably uses inorganic thermocolour pigment.
Coating of the present utility model contains the thermocolour pigment that accounts for coating general assembly (TW) 18-30%, the polyamide resin of 25-50%, the adjuvant of 6-15% and solvent.
Adopt rotary photogravure press with the above-mentioned coating that contains thermocolour pigment, promptly printing ink is imprinted on plastic sheeting, can make the anti-fake mark of the utility model on the stocks such as viscose paper or aluminium foil.Also can be as required, the topped thing of topped one deck at least on ink lay, for example, transparent plastic, compound substance etc.
Mark of the present utility model can be made the label of various color patterns by its recognition point design, and this mark can be printed directly in the packing of product.Or be imprinted on the stock of a band adhesive sticker, during use it is attached in the product or the packing of product and gets final product.
The utility model is compared with existing anti-fake mark has outstanding advantage, and this product can be produced by batch in large quantities, and cost is low.Especially to petty commodities, the pot foods particularly suitable uses coating that the utility model relates to or printing ink to print out and has anti-fraud functional all kinds of colorful, both artistic and practical packing material.In addition, high hot by using high temperature, as cigarette end, match, hot water cup, hot hair dryer or the like thermal source heats this anti-fake mark, and metachromasia can take place; When thermal source leaves, after the temperature decline, revert to original color again.Therefore, with this mark seal or be attached on product or the product, can differentiate the true and false of product.The mark of the utility model provides a kind of effectively false proof or anti-personation means to manufacturer, and is convenient to the consumer and differentiates voluntarily, has safeguarded manufacturer and consumer's interests.
Brief Description Of Drawings:
