The product of making for the method for laser electrochemical aluminum stamping systems on the metal coins of the present invention, it is laser electrochemical aluminum stamping systems 8, be provided with five-layer structure at basement membrane film band 1, be followed successively by from inside to outside by basement membrane one side surface: release layer 2, imaging layer 3, embossed plies 4, aluminium coated 5, gluing layer 6, wherein said gluing layer 6 are two gluing layer structure; Further specifying the described gluing layer 6 of laser electrochemical aluminum stamping systems of the present invention for two gluing layer structure, is two gluing layer structure of different layers structure, and different gluing layer structure are respectively elasticity gluing toughening layer 6-1 and gluing adhesive force enhancement Layer 6-2; Except having good adhesive force, also consider to guarantee its side cut performance when making pattern decoration have wear-resisting, weatherable layer.

When the present invention finished gold stamping rear separation at the laser electrochemical aluminum stamping systems, the separation point position was that described release layer 2 separates with described imaging layer 3, and described release layer 2 tears off thermoprint thing metal coins with described basement membrane film band 1.

The present invention has the described basement membrane film band 1 of holographic pattern to carry out the described aluminium coated 5 of vacuum aluminum-coated formation by vacuum aluminum-plating machine mold pressing, described aluminum layer thickness is take resistance measurement as 2.0 Ω, aluminum layer thickness is measured because the aluminium coated on the vacuum aluminized film is very thin, therefore can not detect its thickness with the thickness measuring instrument of routine, detection method commonly used is electric-resistivity method, to utilize Ohm's law to come the thickness of aluminium coated is measured, according to Ohm's law R=ρ * L/S, the resistance value of unit are metallized film is less, the thickness of its aluminium coated is thicker, otherwise then thinner, the thickness that electric-resistivity method detects aluminium coated represents with sheet resistance, unit is Ω, and the larger explanation aluminum layer thickness of numerical value is thinner, and standard GB/T/T 15717-1995 " vacuum metal thickness of coating test methods electrical resistance method " has been carried out detailed regulation to this method.

The described release layer 2 of prior art usually is to adopt water wax or OP wax, metal coins surface at the release layer after separating can not be printed again, because the dyne value of water wax is low, water wax separates with basement membrane film band 1, water wax is retained on the imaging layer 3, can not realize the surface printing-ink again after the metal coins thermoprint holographic pattern owing to there being wax to exist, the present invention adopts melmac or celluosic resin as mould release, its key is that melmac or celluosic resin are along with basement membrane film band 1 breaks away from embossed plies 4, on imaging layer 3, there is not residual attachment, so can finish again printing-ink, realize the purpose of printing after the holographic pattern thermoprint.

What described imaging layer resin of the present invention adopted is high temperature resistant, wear-resisting resin, makes pattern decoration have wear-resisting, weatherability, has protective effect.

The present invention is in the process of coating gluing layer, prior art is at papery or cloth surface with the electrochemical aluminum foil thermoprint, sticking glutinous object is soft material with respect to metal coins, usually the thickness of coating adhesive is thicker, it is generally acknowledged that gluing is The more the better, what adhere to is more firm, on the contrary at metal coins coating adhesive, because metal coins is the smooth surface that casts out, the adhesive of coating is slightly more, the gluing layer is slightly thicker because glue is soft scraping with regard to producing fearness, softening, caducous problem, analyze by experiment the inventor and think that paper material has certain permeability after paper material applies adhesive, adhesive has sticking stickiness more and strengthens, sticking glutinous firmly situation, and the metal coins smooth surface, and there is not permeability, the slightly more stickiness of will gluing of coating adhesive descends, easily scratch, though can not cohere securely on the metal coins surface, therefore, the adhesive that is coated on the metal coins surface is to get over Bao Yuehao with respect to the adhesive coating layer thickness that is coated on papery thermoprint thing surface, described like this adhesive is strengthened greatly in the firm degree of metal coins surface attachment, and it also is very important selecting suitable and metal that the resin of good compatibility is arranged.Be coated with adhesive with coating machine, gel coating thickness is expressed as by its coating dry measure: 0.7-0.9 g/m2, and side cut property is dried at 140 ℃ of-160 ℃ of drying chambers through bake out temperature like this, and the firmness of adhesive adhesiving metal thing meets design requirement.

In addition for the adaptability problem of ink printing after release layer 2 and the thermoprint, celluosic resin then is the situation that is fit to the thinner ink lay of printing for the printing-ink of metal coins as release layer, and melmac is more suitable for ink lay than the printing of heat-bodied oil China ink as release layer for the metal coins ink printing.
