When a random character for a timepiece is transferred to a display plate for a timepiece as an electrodeposition image, at first, a negative or positive photo-film 1 for an electrodeposition image is formed by photographing or printing. Next, the film 1 is placed on a metal plate 5 through a photoresist 6 and exposed to be developed and the unexposed photoresist 6 is removed to form conductive parts 7 having the shapes of an objective image drawing and a guide image drawing on the surface of the metal plate 5. Subsequently, a metal is precipitated on the conductive parts 7 by an electrodeposition method to form electrodeposition images 8, 9 which are, in turn, bonded to the pressure-sensitive adhesive layer 11 provided on a support base material 10 and peeled from the metal plate 5 to be transferred to the support base material.

Description

The printing transferring method of electrodeposition pattern

The present invention relates to a kind of electrodeposition pattern (as) printing transferring method, promptly, pattern on the display text that will use as clock and watch with electrodeposition process and decorative element etc. (as) be formed at metal sheet surface, with this pattern (as) (electrodeposition pattern) peel from metallic plate, after being transferred on the supporting substrate materials such as film, be transferred to again clock and watch with display board etc. by on the bur.

Recently, have at display text of using as clock and watch and decorative element etc. on the object of trickle, complicated shape, be extensive use of following transfer technique.

On the surface of metallic plate, form conductive part by these pattern shape, on this conductive part by the electrodeposition process precipitating metal, form the electrodeposition pattern of metallic film, by binding agent this electrodeposition pattern is transferred to supporting such as film with on the matrix material, and keep this pattern, then, pass through binding agent again, with this electrodeposition pattern when the matrix material of supporting strips down, be transferred to clock and watch and attached on the thing with display board etc.

Here, at the lip-deep electrodeposition pattern that will be formed at above-mentioned metallic plate when metallic plate strips down, be transferred on the matrix material of supporting and when being kept, in order to prevent to produce defective because of coming off of electrodeposition pattern, the binding agent that preferably will have strong cohesive force is applied to the substrate material surface of supporting, and by this binding agent electrodeposition pattern is transferred on the matrix material of supporting.

Yet, as described above, use is stained with the supporting matrix material of the binding agent of the very strong cohesive force of tool, and on this supporting substrate material, shift and when keeping electrodeposition pattern, then because this supporting substrate material is quite big to the cohesive force (confining force) of electrodeposition pattern, when supporting substrate material is peeled off electrodeposition pattern, it is attached at just becomes very difficult on the thing that is stuck.

Therefore, up to now, widely used method is, on as supporting substrate materials such as bands, adhere to the more weak binding agent of cohesive force, by this more weak binding agent electrodeposition pattern is remained on the supporting substrate material, and in the inboard of electrodeposition pattern one side, promptly, one side of exposing in the time of on being transferred to supporting substrate material, the binding agent that has strong cohesive force in the coating, by the table that is positioned at electrodeposition pattern, in cohesive force strong and weak different of binding agent of two side faces, electrodeposition pattern is stripped down from supporting substrate material, and it is attached at by bur (please refer to the spy and open clear 59-140384 communique).

In addition, method as the inboard one side of binding agent only being coated electrodeposition pattern, existing people proposes: be provided for preventing that in the outer peripheral edges of literal etc. sheltering of too much electro-deposition from using electrodeposit, this is sheltered with electrodeposit and is overlying on when making the coating binding agent after the shelter on the literal etc., it is discardable method (for example, please refer to special public clear 63-18674 communique); And, get ready in advance have the opening portion that is slightly larger than electrodeposition pattern shelter cover (film), cover around the electrodeposition pattern on the supporting substrate materials such as being transferred to thin slice from metallic plate with this mask cover, the method (for example, please refer to special fair 4-43988 communique) of coating binding agent under this state; Or the like.

Yet, reality is, example as above-mentioned prior art, desire is used and is adhered to the supporting substrate material with the more weak binding agent of cohesive force, to be formed at that electrodeposition pattern on the metallic plate is peeled off and when being kept simultaneously, then because of the deficiency of this cohesive force, electrodeposition pattern easily comes off, and produces defective; For preventing this situation, use when being stained with the strong binding agent of cohesive force, then peel off and the become difficulty of electrodeposition pattern from this supporting substrate material; Can't take into account above-mentioned two kinds of situations simultaneously.

Though also the someone considers that metal sheet surface is done the coating demoulding to be handled, and forms electrodeposition pattern more thereon, then, with binding agent electrodeposition pattern is transferred to film etc. and gets on weak cohesive force.But, like this, because the plating stress that generates in the electro-deposition, and electrodeposition pattern is come off from metallic plate.

And, though cohesive force a little less than, but still have enough cohesive forces that electrodeposition pattern is peeled off and kept from metallic plate, therefore, just produced the residual gluey phenomenon of this glue residue in the surface of electrodeposition pattern.Not only like this, the described ground of public clear 63-18674 communique of and for example above-mentioned spy and special fair 4-43988 communique also must only be coated binding agent on the inboard one side of electrodeposition pattern.

In view of the foregoing, the objective of the invention is to, a kind of printing transferring method of electrodeposition pattern is provided, use is stained with the supporting substrate material of the binding agent with strong cohesive force, both the electrodeposition pattern that is formed at metal sheet surface can be transferred to the thing that is stuck, and can save binding agent is only coated cumbersome process on the inboard one side of electrodeposition pattern, operation is simplified.

For achieving the above object, the printing transferring method of electrodeposition pattern of the present invention is characterised in that, on the surface of metallic plate, form electrodeposition pattern, on this pressure sensitive adhesives layer of the supporting substrate material that is provided with pressure sensitive adhesives, attach above-mentioned electrodeposition pattern it is peeled off transfer from metallic plate, reduce the cohesive force of above-mentioned pressure sensitive adhesives layer again, then at side coating cohesive force fixing the use binding agent stronger of the maintenance electrodeposition pattern of above-mentioned supporting substrate material than the cohesive force of above-mentioned pressure sensitive adhesives layer, by this fixing binding agent of using, with above-mentioned electrodeposition pattern when above-mentioned supporting substrate material strips down, be attached at the surface of the thing that is stuck.

Here, the cohesive force of above-mentioned pressure sensitive adhesives layer weakens w-curable type binding agent formation pressure sensitive adhesives layer and irradiation ultraviolet radiation; Or form the heating of pressure sensitive adhesives layer with the binding agent of heat hardening type; Or form with timeliness constrictive type binding agent and to make after the pressure sensitive adhesives layer it stand the timeliness variation to wait and carry out.

According to the present invention who constitutes by aforesaid content, pressure sensitive adhesives layer with strong cohesive force is set on supporting substrate material, by this pressure sensitive adhesives layer electrodeposition pattern is peeled off and is transferred on the supporting substrate material simultaneously from metallic plate, under this state, weaken the cohesive force of above-mentioned pressure sensitive adhesives, thus, make it to be same as the state that keeps electrodeposition pattern with weak binding agent, the thing surface that is stuck be peeled off and be pasted on simultaneously to the fixing binding agent of using of maintenance electrodeposition pattern one side by coating supporting substrate material can from above-mentioned supporting substrate material with above-mentioned electrodeposition pattern.

In addition, to pressure sensitive adhesives with fixing selected, make after the cohesive force of pressure sensitive adhesives descends with binding agent, the pressure sensitive adhesives layer and fixing with the cohesive force on the interface of adhesive layer greater than thing and the fixing cohesive force on the interface of binding agent of being stuck.Thus, can will fix with adhesive-coated in the whole side of maintenance electrodeposition pattern one side of supporting substrate material.

On the other hand, as shown in Figure 2, on metal foil 5, be coated with liquid protectant, dry film protective agent or printing, prepare printing down with photoresists 6 such as protective agent China inks as stainless steel etc.

Then, as shown in Figure 3, on above-mentioned metallic plate 5, place above-mentioned film 1, photoresists 6 are sandwiched in therebetween, under this state, expose (in the figure with exposure machine etc., the part of representing with oblique line in the film 1 is equivalent to above-mentioned target pattern Fig. 2 and pattern Fig. 3 is used in the location, for having covered the part of light).

Develop after the exposure, remove unexposed photoresists 6a (see figure 3), thus, as shown in Figure 4, on the surface of metallic plate 5, form the shape conductive part 7 of using the shape of pattern Fig. 3 by above-mentioned target pattern Fig. 2 and location.

Then, as shown in Figure 5, ( electrodeposition pattern 8,9, precipitating metal on above-mentioned conductive part 7 is with electrodeposition pattern 8 Hes of metallic film formation by the shape of above-mentioned target pattern Fig. 2, by the electrodeposition pattern 9 of location with the shape of pattern Fig. 3 by electrodeposition process.

But, above-mentioned electrodeposition pattern 8 becomes 3,6,9 and 12 digital shape, but from drawing, can only see these digital font width from the plane.In the inside of above-mentioned electrodeposition pattern, be formed with locating hole (not shown) by the shape face perforation of above-mentioned sign 4 again.

Here, as the metal that forms above-mentioned electrodeposition pattern 8,9, as using the nickel metal, can be with nickelous sulfate liquid as Watts bath (ワ ッ ト liquid), electric deposition nickel on conductive part 7; As the electrodeposition condition of this moment, can be to the electro-deposition effective area of for example 150mm * 150mm, the logical 3A/dm that goes up ²Electric current 3 hours, can obtain the electrodeposition pattern of 100 μ m * 10 μ m.

Certainly, except above-mentioned nickel, also can on conductive part, separate out as metal arbitrarily such as gold, silver, copper, iron or its alloy, to form electrodeposition pattern, in addition, change electrodeposition condition, also can obtain electrodeposition pattern in 20-300 mu m range for example, any width.

Below, as shown in Figure 6, metallic plate 5 impregnated in the solution, after the photoresists 6 on having removed metallic plate 5, can on the surface of above-mentioned electrodeposition pattern 8,9, carry out decorating (painted) on demand as the surface-treated coat of metal, electrophoresis plating lacquer, spraying plating, printing, electrostatic spraying or vacuum evaporation etc.

Like this, on the surface of metallic plate 5, form after the electrodeposition pattern 8,9 of pressing required form formation with electrodeposition process, again as shown in Figure 7, this electrodeposition pattern 8,9 is transferred on the supporting substrate materials 10 such as film, at this moment, on the one side of this supporting substrate material 10, coat the strong cohesive force of tool, along with the awarding and pressure sensitive adhesives layer 11 that cohesive force such as timeliness variation dies down of energy, above-mentioned electrodeposition pattern 8,9 is pasted on this pressure sensitive adhesives layer 11, make it to peel off from metallic plate 5.

Like this, pressure sensitive adhesives layer 11 by the strong cohesive force of tool, electrodeposition pattern 8,9 is transferred on the supporting substrate material 10 from metallic plate 5, thus, can be when metallic plate 5 be peeled off at the electrodeposition pattern 8,9 that will be formed at metallic plate 5 surfaces, be transferred on the supporting substrate material 10 and when being kept, prevent coming off of electrodeposition pattern 8,9 and produce defective.

Above-mentioned pressure sensitive adhesives layer 11, can by as UV cured type, heat hardening type, and the pressure sensitive adhesives of timeliness constrictive type form.

Here, representative example as the pressure sensitive adhesives of UV cured type has: fusion have the addition polymerization compound of unsaturated bond more than two and have epoxy radicals, be pressure sensitive adhesives as the rubber of the Photoepolymerizationinitiater initiater of the optical polymerism compound of alkoxy silane and so on and carbonyls and organosulfur compound, peroxide, amine, salt based compound; Reach (seeing that the spy opens clear 60-196956 communique) such as acrylic ester pressure sensitive adhesives.The blended amount of optical polymerism compound, Photoepolymerizationinitiater initiater is respectively 10-500 weight portion and 0.1-20 weight portion with respect to per 100 weight portion substrate polymers usually.

Acrylic ester polymer, except common enumerate (seeing special public clear 57-54068 communique, special public clear 58-33909 communique etc.), also can use the polymer (seeing special public clear 61-56264 communique) that on side chain, has the radical reaction unsaturated group, and the polymer that in molecule, has epoxy radicals.

Again, for example can enumerate as the addition polymerization compound with 2 above unsaturated bonds, the polyalcohol of acrylic or methacrylic acid is ester or oligoester, epoxy base system or polyurethane series compound etc.

Have again, also can append and mix as epoxy functional crosslinking agent ethylene glycol diglycidylether and so on, that have the epoxy radicals more than 1 or 2 in the molecule, to improve cross-linking effect.

When the binding agent that uses UV cured type forms pressure sensitive adhesives layer 11, become possibility for making ultraviolet treatment with irradiation, the films that the needs use is transparent etc. are as supporting substrate material 10.

Again, representative example as the pressure sensitive adhesives of heat hardening type, the crosslinking agent of polyisocyanate salt, melmac, amine-epoxy, peroxide, metallo-chelate and so on of can having enumerated fusion, and to also have the rubber of the cross-linking regulator be made up of multi-functional compounds such as divinylbenzene, glycol diacrylate, trimethylol-propane trimethacrylates etc. in case of necessity be pressure sensitive adhesives and acrylic ester pressure sensitive adhesives etc.

Have again,, evaporate the pressure sensitive adhesives that causes that cohesive force reduces gradually along with the time thereby can enumerate by the solvent that mixes as the pressure sensitive adhesives of age-hardening type.

Then, after the cohesive force that reduces above-mentioned pressure sensitive adhesives layer 11, as shown in Figure 8, the fixing binding agent 12 of using that cohesive force is stronger than the cohesive force of above-mentioned pressure sensitive adhesives layer 11, coat the whole side of electrodeposition pattern one side of above-mentioned supporting substrate material 10 with spray-on process, then, as required, processing release paper 13 is pasted on the inboard one side of this electrodeposition pattern 8,9 of fixing the coated face of using binding agent 12.

Here, when the pressure sensitive adhesives with UV cured type forms above-mentioned pressure sensitive adhesives layer 11, as shown in the drawing, from surface one side of electrodeposition pattern 8,9 be, from with the opposite side of a side that keeps electrodeposition pattern 8,9, irradiation ultraviolet radiation to supporting substrate material 10, so, can make the cohesive force of pressure sensitive adhesives layer 11 become extremely a little less than.

In addition, when the pressure sensitive adhesives with the heat hardening type forms pressure sensitive adhesives layer 11, by supporting substrate material 10 is heated; When forming the pressure sensitive adhesives of age-hardening type, then make it to take place timeliness and change; A little less than two kinds of methods all can make the cohesive force of pressure sensitive adhesives layer 11 become extremely thus.

Have again, also can after face one side that will fix the maintenance electrodeposition pattern 8,9 of coating supporting substrate material 10 with binding agent 12,, weaken the cohesive force of pressure sensitive adhesives layer 11 with above-mentioned same.

Follow again, as shown in Figure 9, keep the fixing of face one side by the electrodeposition pattern of coating supporting substrate material 10 with binding agent 12, under peeling off, in the above-mentioned electrodeposition pattern 8,9, its clock and watch that adhere to, are fixed in the thing that is stuck are used on the surface of display board 14 from above-mentioned supporting substrate material 10.

Here, as shown in figure 10, fixing the alignment pin 16 that is provided with projection on the fixed head 15 of clock and watch with display board 14,, can determine the position of 8 pairs of clock and watch of electrodeposition pattern with display board 14 by this alignment pin 16 and the locating hole (not shown) of being located on the above-mentioned electrodeposition pattern 9.

At this moment, as aforementioned, because the cohesive force of above-mentioned pressure sensitive adhesives layer 11 weakens, be in as the state that keeps electrodeposition pattern 8,9 by weak binding agent, can keep the fixing of face one side by the electrodeposition pattern of coating supporting substrate material 10 with binding agent 12, with above-mentioned electrodeposition pattern 8 when above-mentioned supporting substrate material 10 is peeled off, be pasted on the surface of clock and watch with display board (thing is stuck) 14.

Select two binding agents 11,12, make this pressure sensitive adhesives layer 11 and said fixing with the cohesive force on the interface of binding agent 12 greater than being in clock and watch with display board 14 and fixing with the cohesive force on the interface of binding agent 12, thus, can make fixingly not adhere to clock and watch with binding agent 12 and use on the display board 14.

For example, at the acrylic ester pressure sensitive adhesives of used fusion optical polymerism compound and Photoepolymerizationinitiater initiater when forming the pressure sensitive adhesives of above-mentioned pressure sensitive adhesives layer 11, it is fixing with binding agent 12 to do this, can use the binding agent similar with the pressure sensitive adhesives that forms pressure sensitive adhesives layer 11, promptly, the acrylic ester pressure sensitive adhesives that substrate polymer is only arranged of not fusion optical polymerism compound and Photoepolymerizationinitiater initiater, after its coating, thermalization is 9 hours in 40 ℃ of atmosphere.Thus, can make pressure sensitive adhesives layer 11 and said fixing use display board 14 and fix the cohesive force of using on the interface of binding agent 12 greater than being in clock and watch with the cohesive force at the interface of binding agent 12.And, the binding agent beyond the fixed position all can be peeled off removal.

In addition, also can be by masking film etc., will be fixing only coat the inboard one side of electrodeposition pattern 8 with binding agent 12, can use any fixing binding agent 12 of using thus.

The present invention is made of foregoing, therefore, use scribbles the supporting substrate material of the pressure sensitive adhesives layer of the strong cohesive force of tool, can be when preventing that it from coming off, the electrodeposition pattern that is formed at metal sheet surface is peeled off and is transferred on the supporting substrate material from metallic plate, can prevent to cause the generation of defective thus because of coming off of electrodeposition pattern; Simultaneously owing to weakened the cohesive force of above-mentioned pressure sensitive adhesives layer, can with electrodeposition pattern when supporting substrate material is successfully peeled off, it is transferred on the thing that is stuck.

Especially, become extremely by the cohesive force that makes above-mentioned pressure sensitive adhesives layer a little less than, can when prevent that residual slurry phenomenon from taking place, can successfully electrodeposition pattern be peeled off from supporting substrate material, and be attached at simultaneously on the thing that is stuck.

And, select two kinds of binding agents, make be in above-mentioned cohesive force after weakening the pressure sensitive adhesives layer and fixing with the cohesive force on the interface of binding agent greater than being in be stuck thing and the fixing bonding force of using on the interface of binding agent, can the whole side that keep face one side with adhesive-coated in the electrodeposition pattern of supporting substrate material will be fixed thus, and need not binding agent is only coated the trouble operation of the inboard one side of electrodeposition pattern, reach the simplification of operation.
