The decorative panel 10 of the invention described above is owing to decorative pattern 3 is fixed in the recess 2 of adherend 1 by adhesive layer 4, even therefore small decorative pattern the phenomenon that image comes off can not take place yet.For example, this adhesive layer 4 is by the mixed adhesive (i) of hotmelt and ultraviolet-curing adhesive when forming, even under the situation that the cohesive that causes ultraviolet-curing adhesive because of ultraviolet illuminate condition is improper does not fully display, also can rely on replenishing of hotmelt to reach desired bonding force, thereby guarantee decorative pattern is firmly fixed.In addition, by using hotmelt or adhesive, need not to carry out ultraviolet ray and just shine fixedly decorative pattern.
In addition, by the aggregate thickness of setting decorative pattern 3 and adhesive layer 4 as mentioned above, the degree of depth of recess 2, therefore the wedge angle portion of decorative pattern end can not protrude in the adherend surface, even the picture pattern of clear-cut margin also can prevent to wear and tear and the injury when contacting.Also have,, therefore when decorative pattern is made of metal, can effectively utilize the original metallic luster of metal pattern, improve ornamental because expose on the decorative pattern surface.
Certainly also allow to be formed for the resin bed of painted grade in the present invention on the decorative pattern surface.When decorative pattern was etching pattern, side etching caused the image side to become coarse sometimes.In this case, at image side residue adhesion adhesive is arranged easily.In order to prevent the appearance of this problem, can form resinous coat in the surface and the side of decorative pattern.Utilize resinous coat to make the side smooth smooth, can reduce the residual of adhesive thus.This resinous coat is formed by thermohardening type polymer of ultraviolet hardening polymer, acrylic acid and the epoxy mixed stocker and the polyurethane series of acrylic acid series etc., there is no particular limitation to its thickness, better be 5～25 μ m, be more preferably 5～20 μ m, the spy is well 5～25 μ m.
Then, the manufacture method to decorative panel 10 of the present invention describes.
At first, decorative pattern 3 integrally temporarily is bonded on the bearing part 11.The Production Example of this decorative pattern 3 is carried out as adopting described electro-deposition figure methods such as Japanese patent laid-open 7-331479 communique, Japanese patent laid-open 8-27597 communique, in addition, also can be by adopting sheet adhesive etc. as bearing part 11, metal forming is attached on this sheet adhesive, utilize etching method, pressing, laser scribing method that this metal forming is formed pattern, form the decorative pattern 3 that integrally temporarily is bonded on the sheet adhesive thus.
Among the present invention, can when forming decorative pattern 3, form the process management pattern 9 of the periphery that is trapped among decorative pattern 3.This process management finally will be removed with pattern 9, but can be used as mask when formation adhesive layer 4 described later.In addition, can also be in the hole that process management is formed for locating etc. with pattern 9.
Here, integrally temporary transient bonding decorative pattern 3 is meant following state, that is, the state of character and graphic patterns such as the manufacturing company's title that will represent with whole decorative pattern, trade name, trade mark is fixed on the bearing part 11, and is strippable.
From being easy to make equal angles, this decorative pattern 3 is electro-deposition figure or etching pattern preferably.
Etching pattern for example can form by following method, and this method is: employing sheet adhesive etc. are attached to metal forming on this sheet adhesive as bearing part 11, after forming etchant resist on this metal forming, by exposure, develop, and carry out etching, remove etchant resist at last.Adopt this method to obtain etching pattern integrally temporarily to be bonded in the state on the sheet adhesive as decorative pattern.In order in the operation of back etching pattern to be peeled off easily, sheet adhesive preferably adopts the ultraviolet hardening sheet adhesive.
In addition, surface and the side that is preferably in decorative pattern 3 is provided with aforesaid resinous coat.When resinous coat was set, at state shown in Figure 2, promptly decorate pattern 3 and integrally temporarily be bonded under the state on the bearing part 11, coating or spraying formed resin-coated material resin, with resin solidification.Resinous coat change to paste operations through 2 times described later, and what be configured in decorative panel 10 exposes the face side.This resinous coat is set, can prevents to form the adhesive of adhesive layer and paste employed commentaries on classics in the operation and paste surface and the side that the adhesive residue of band sticks to decorative pattern 3 changeing.Therefore, hot candied phenomenon can not take place in adhesive in changeing subsides operation and bonding process, can produce the decorative panel 10 of free from smutting during.
In order to reach same purpose, can carry out lift-off processing on the surface of decorative pattern 3.Here, remover preferably adopts the silicon series stripping agent.In addition, also can after being provided with resinous coat, carry out lift-off processing to the resinous coat surface.Like this, not only can prevent the residue adhesion of adhesive, can also described later will change at last to paste be with 12 when decorative pattern 3 is peeled off, prevent that decorative pattern 3 is with 12 sides to be stripped from together attached to changeing to paste.
In the present invention, good especially is according to the described method of Japanese patent laid-open 7-331479 communique, as shown in Figure 2, forms conductive cell envelope 5 on the surface of metallic plate 6, used as bearing part 11, utilize the electro-deposition figure method to form decorative pattern 3 on conductive cell envelope 5 surfaces.
Then, decorative pattern 3 commentaries on classics that are formed at bearing part 11 surfaces being attached to the commentaries on classics subsides with adhesive phase 7 is with on 12.Concrete way is, paste by the commentaries on classics that will constitute by base material 8 and adhesive phase 7 and to be with 12 to be attached to after decorative pattern forms on the face, to change to paste is with 22 to peel off from bearing part 11, can be stripped from the state that decorative pattern 3 is bonded on the adhesive phase 7 thus, be with on 12 thereby decorative pattern 3 commentaries on classics are attached to the commentaries on classics subsides.When forming etching pattern, adopt under the situation of sheet adhesive as bearing part 11, select its bonding force to be with 12 as changeing to paste greater than the material of this sheet adhesive.Particularly when bearing part 11 adopts the ultraviolet hardening sheet adhesive, carry out ultraviolet curing after etching pattern forms, the bonding force of bearing part side is reduced, so just can decorative pattern 3 be changeed be attached to change to paste at an easy rate and be with on 12.
As shown in Figure 2, formed conductive cell envelope 5 on the surface of metallic plate 6, when these conductive cell envelope 5 surfaces have formed decorative pattern 3, preferably peel off as shown in Figure 3, making decorative pattern 3 be clipped in conductive cell envelope 5 and change paste is with between 12, then as shown in Figure 4, peel off conductive cell envelope 5 from the decorative pattern face.Through this operation, can be with 12 o'clock in that decorative pattern 3 is changeed to be attached to change to paste from bearing part 11, prevent that decorative pattern 3 is subjected to dispersing of excessive distortional stress and decorative pattern 3.
When adhesive phase 7 adopts adhesive, preferably on decorative pattern 3, spray releasing agent in advance.Like this, can described later will change at last to paste be with 12 when adherend is peeled off, prevent that decorative pattern 3 is with 12 sides to be stripped from together attached to changeing to paste.
Change to be attached to change to paste in final operation, to be changeed and be attached on the adherend with the decorative pattern 3 on 12.Therefore, change to paste to use weak adhesive or to be subjected to ultraviolet ray and penetrate ultraviolet hardening adhesive that the back bonding force can reduce etc. with releasable with 12 adhesive phase 7.
But, when decorative pattern 3 surfaces have formed resinous coat and when carrying out lift-off processing, because it is little that paste with the bonding force between 12 on decorative pattern surface and changeing, therefore can adopt various adhesives as changeing the adhesive phase 7 that pastes with 12, and be not limited to weak adhesive or ultraviolet hardening adhesive.Particularly decorative pattern 3 finally is fixed on adhesive layer 4 identical or similar adhesives on the adherend, the adhesive and the adhesive phase 7 that ooze out from decorative pattern 3 can be removed from the decorative pattern periphery together by adopting with being used for.
The adhesive that forms adhesive layer 4 as previously mentioned and its similar adhesive be meant that though compositions, rerum natura are different from the adhesive that forms adhesive layer 4, but belong to the interior adhesive of scope of explanation of the adhesive of aforementioned relevant formation adhesive layer 4.For example, at adhesive layer 4 is that mixed adhesive (i) by hotmelt and ultraviolet-curing adhesive is when forming, though be meant that with its similar adhesive the adhesive layer 4 that uses with reality is different on the proportioning of hotmelt and ultraviolet-curing adhesive, its proportioning is in the adhesive within the described scope of this specification.
Preferably the base material 8 that pastes with 12 in commentaries on classics earlier carries out Corona discharge Treatment, and then forms adhesive phase 7.Can improve the adhesion strength of base material 8 and adhesive phase 7 like this, in the end will change to paste and be with 12 when adherend is peeled off, can prevent that the adhesive residue of adhesive phase 7 from sticking on the decorative pattern 3.
In addition, when adhesive phase 7 contained ultraviolet-curing adhesive, base material 8 adopted various transparent or semitransparent resin moldings.When containing ultraviolet-curing adhesive, adhesive phase 7 comprises following two kinds of situations, a kind of is to change subsides to be general UV band (ultraviolet hardening adhesive tape) with 12, and another kind is the mixed adhesive (i) of adhesive phase 7 for hotmelt and ultraviolet-curing adhesive.
As mentioned above, with this decorative pattern 3 change be attached to the commentaries on classics with adhesive phase 7 paste be with on 12 after, when adhesive phase 7 contained ultraviolet-curing adhesive, as shown in Figure 5, irradiation ultraviolet radiation reduced bonding force.At this moment, by from 8 side irradiation ultraviolet radiations of base material, the whole adhesive phase 7 that contains ultraviolet-curing adhesive is fully solidified, making fixedly thus, the bonding force of the part of decorative pattern 3 descends.
Then, as shown in Figure 6, form adhesive layer 4 at the face of fixing decorative pattern.The thickness of adhesive layer 4 better is 10～60 μ m, is more preferably 15～50 μ m, and the spy is well 15～30 μ m.
The composition of the adhesive that adhesive layer 4 is used is with aforementioned identical, can be with to change the composition that pastes with 12 adhesive phase 7 identical, also can be different, but preferably have identical or similar composition.
The formation of adhesive layer 4, for example with above-mentioned adhesive as required with behind the solvent dilution, adopt silk screen print method, spraying process etc. to carry out, preferably adopt silk screen print method to carry out.
When forming adhesive layer 4, also can adopt mask with shape and decorative pattern 3 essentially identical peristomes.That is, under the state that coincides by the position at peristome that makes mask and decorative pattern 3, the coating spraying binder can form adhesive layer 4 at the face that exposes of decorative pattern 3.In addition, also can form process management as mentioned above with pattern 9, used as mask.
When having formed the process management usefulness pattern 9 that is used as mask, behind coating, spraying binder, remove process management pattern 9.
Through this operation, shown in 6, can be only decorative pattern 3 expose face and its periphery forms adhesive layer 4, can reduce being attached to oozing out of adherend 1 back adhesive.
Below, carry out explanation on the other hand, prepare to have the adherend 1 (Fig. 7) of shape and decorative pattern 3 essentially identical recesses 2.Adherend 1 is made by metal and various synthetic resin, and there is no particular limitation to its material.In addition, also there is no particular limitation to the thickness of adherend 1, can be all thickness according to the difference of the purposes of decorative panel 10, but be generally about 500～1000 μ m.The method of formation recess 2 has the whole bag of tricks with the difference of the material of adherend 1, selects suitable method according to material.For example, can be press forming and etching method, in addition, if synthetic resin then can adopt mould to be shaped.The contour shape of recess 2 and decorative pattern 3 are basic identical.That is, width, the length setting with recess 2 becomes identical or more slightly bigger than it with decorative pattern 3.When setting recess slightly bigger, similar and set than the standard about big 100～300 μ m of width, length of decorative pattern according to shape and decorative pattern 3.The degree of depth of recess 2 can be done suitably to set as previously mentioned according to the thickness of decorative pattern 3 and adhesive layer 4.
Then, the recess of adherend 1 and the position of decorative pattern 3 are coincided, decorative pattern 3 is entrenched in the recess, make decorative pattern 3 be fixed on (Fig. 8) in the recess by adhesive layer 4 by adhesive layer 4.
Then, when adhesive layer 4 is formed by the mixed adhesive of hotmelt and ultraviolet-curing adhesive, paste band side irradiation ultraviolet radiation (Fig. 9), and paste the band side and heat or heat and pressurize (Figure 10) from changeing from changeing.In heating or heating and pressurized treatments, better be to use the size heat resistant rubber mint-mark 13 identical with decorative pattern 3.Its condition can suitably be selected according to the character of employed hotmelt, but the rubber surface temperature is preferably 90～150 ℃, more preferably 90～130 ℃, and pressure is preferably 3～5kg/cm
2, press the sticking time be preferably 5 seconds～15 seconds.During irradiation ultraviolet radiation, the following adhesive layer 4 that is positioned at decorative pattern 3 can not be subjected to ultraviolet irradiation owing to covering of decorative pattern 3, keeps uncured state, so can decorative pattern 3 be fixed in the recess with enough bonding forces.In addition, even, also can utilize hotmelt to supply required bonding force, therefore can guarantee decorative pattern 3 is fixed in the recess because of the incorrect ultraviolet-curing adhesive over-curing that makes of ultraviolet ray irradiation.On the other hand, the adhesive that oozes out at the periphery of decorative pattern 3 is subjected to the ultraviolet ray irradiation and polymerizing curable and change the adhesive phase 7 that pastes with 12 and form incorporate solidfied material.Particularly change to paste when being formed by identical or similar adhesive with adhesive layer 4 with 12 adhesive phase 7, both are combined into an integral body securely.
In addition, when adhesive layer 4 is formed by hotmelt, as shown in figure 10, be with 12 sides, promptly heat or heat and pressurize, can decorative pattern 3 be fixed in the recess by adhesive layer 4 thus from base material 8 sides with 12 from changeing to paste.On the other hand, adhesive and the adhesive phase 7 that oozes out at the periphery of decorative pattern 3 forms incorporate solidfied material.
At last, to change to paste and be with 12 when adherend 1 is peeled off, on base material 8, adhesive phase 7 and the adhesive layer that oozes out from decorative pattern with the solidfied material of adhesive along with being with 12 to be stripped from together, because the adhesive and the adhesive phase 7 that ooze out at the periphery of decorative pattern 3 become one, therefore the periphery of adherend 1 surface and decorative pattern 3 can residual adhesive layer with the solidfied material of adhesive.Consequently, decorative pattern 3 is fixed in the recess of adherend 1 by adhesive layer 4, thereby obtains decorative panel of the present invention 10 shown in Figure 1.
If particularly resinous coat is set, then can prevents to form the adhesive of adhesive layer 4 and paste employed commentaries on classics in the operation and paste changeing with 12 adhesive phase 7 residue adhesions surface and side at decorative pattern 3 in the surface and the side of decorative pattern 3.Therefore, hot candied phenomenon can not take place in adhesive in changeing subsides operation and bonding process, can produce the decorative panel 10 of free from smutting during.
In addition, if lift-off processing is carried out on the surface at decorative pattern 3, not only can prevent that then adhesive residue from sticking to decorative pattern 3 surfaces, can also be with 12 when decorative pattern 3 is peeled off will changeing to paste, guarantee between commentaries on classics subsides band and decorative pattern surface, to peel off, be with 12 sides to be stripped from together so can prevent decorative pattern 3 attached to changeing to paste, guarantee that decorative pattern 3 is fixed in the recess of adherend 1.
When adhesive layer 4 contains ultraviolet-curing adhesive, as required by carrying out burin-in process, can further improve the bonding force of the uncured thing (adhesive) of ultraviolet-curing adhesive, decorative pattern 3 is bonded in securely in the recess of adherend 1.
Also have, when the adhesive that constitutes adhesive layer 4 contained hotmelt, after the heat resistant rubber mint-mark, the temperature that is preferably in adhesive was under the state more than 50 ℃, to peel off rapidly to change to paste and be with 12.Because temperature is low more, then the bonding force of hotmelt is strong more, be difficult to more peel off, in addition, sometimes at the residual adhesive that oozes out of the periphery of decorative pattern 3.
Also can decorative panel bonding securely, that image also can not come off when being subjected to impacting even the invention provides small decorative pattern.In addition, even also provide the sharp image in end also can prevent to wear and tear and the injury when contacting and can effectively utilize the decorative panel and the manufacture method thereof of the original metallic luster of decorative pattern.In addition, the present invention also provides the adhesive that is used for fixing decorative pattern can not ooze out or remain in the good decorative panel of outward appearance on the adherend from decorative pattern.
