Description
Technical field
The present invention relates to the transfer materials of usefulness for the surface of decorated resin molded article.
Background technology
Always, as the method on the surface of decorated resin molded article, the transfer printing simultaneously that is shaped is arranged.The so-called transfer printing simultaneously of being shaped be on substrate successively lamination sandwich in the forming metal mould by the transfer materials of the transfer printing layer of forming by peel ply, patterned layer, adhesive linkage etc., resin injection is full of in the die cavity, cool off and when obtaining resin forming product behind the bonding in its surface transfer materials, peel off substrate, transfer printing layer is transferred on the resin forming product surface and the method for decorating.
Usually, the transfer materials that uses in the while transfer printing that is shaped is to print on rectangular substrate according to the roll width of printing machine to form each layer, behind the suitable width of its cut-out of big young pathbreaker (cutting) one-tenth that is transferred thing, is used for carrying out transfer printing.
In this occasion, exist the impact that part is touched because of the cutter when cutting 130 that cuts of transfer materials, as shown in Figure 12 and Figure 13, cause the such shortcoming of paper tinsel obscission of the printing ink covering piece 131 formed by peel ply 104, back-up coat 107, patterned layer 105, adhesive linkage 106 etc. the sur-face peeling of formed release layer 103 from the substrate 102.This is because between the substrate and transfer printing layer of transfer materials, not only for the part of transfer printing even do not have cause on the good fissility for the part of transfer printing yet.Paper tinsel comes off as the many occasions of transfer printing layer patterned layer, perhaps is necessary to be provided with the occasion of evaporation layer as patterned layer, to the occasion that the such peel ply of bar code transfer materials has to thicken, and the occasion that functional layer is many, the thickness of transfer printing layer is big more to be produced more significantly.
As a result, the printing ink covering piece is attached on the transfer materials once more sometimes, enters to be transferred between thing and the transfer printing layer when transfer printing.In addition, if be attached at the printing ink covering piece under the state at the back side of transfer materials and form transfer printing simultaneously, then the printing ink covering piece is attached on the cavity surface of metal pattern sometimes, produces the indenture (being also referred to as impression) that the printing ink covering piece causes on the surface of formed products.
Therefore, paper tinsel in order to prevent to cut comes off, have when on the substrate 102 release layer 103 being set, release layer 103 is set as the figure of the band shape except running into the part that cuts position 108, the scheme (with reference to Fig. 4 and the flat 11-58584 communique of Te Kai) of the transfer printing layer of being made up of peel ply 109, patterned layer 105, adhesive linkage 106 etc. is set thereon.
In addition, replace release layer 103 is set all sidedly, can consider transfer printing layer all is set as diagram shape, transfer materials 101 is constituted cutter does not contact transfer printing layer (with reference to Fig. 5) when cutting.
But form the occasion of transfer printing simultaneously at transfer materials 101 with the formation shown in Fig. 4, if with the sort of metal pattern 111 that has side gate 113, then as shown in Figure 10, the gate part 113 that is communicated in the shaping resin of die cavity 112 be contacted with near the cutting the position 108 of transfer materials 101 (80 of Figure 10 is zones that release layer 103 exists, the 81st, release layer 103 non-existent zones.), the adhesive linkage 106 that the down gate of shaping resin is fused to transfer materials 101 (as shown in Figure 11, because under the injection moulding state, the part that can peel off only is 84 a part as the interface of the peel ply of being stripped from after transfer printing 103 and peel ply 104, do not peel off in other parts, side in shaping resin portion 120 has adhesive linkage 106, there is not strippable part, so the down gate of shaping resin is deposited on the adhesive linkage 106), exist transfer materials 101 breakages etc. and can't carry out the such problem of progressive forming (with reference to Fig. 6).Particularly as shown in Figure 10 in the occasion that forms transfer printing simultaneously with two transfer materials 101 on the two sides of formed products,, more be easy to generate above-mentioned phenomenon so become because shaping resin passes through with the form of the end that is contacted with certain transfer materials 101.
In addition, in the transfer materials of the formation shown in Fig. 5, though improve the occasion of the surface strength of transfer printing formed products in hope, as peel ply 109 ionizing radiation cured resin, but then its thickness is limited because if partly by print process the ionizing radiation cured resin is graphically formed, and can't obtain the such problem of enough surface strengths so exist.

Patterned layer 5 is stacked on (with reference to Fig. 2) on the ionizing radiation cured layer 4 all sidedly.In addition, also lamination (with reference to Fig. 1) partly of patterned layer 5.Patterned layer 5 forms as printed layers usually.Material as printed layers, with containing with resins such as polythylene resin, polyamide-based resin, polyester resin, propylene resin, polyurethanes resin, polyvinyl acetal resinoid, polyester urethane resinoid, cellulose esters resinoid, alkyd resins, just passable as the coloring printing ink of colouring agent with the pigment or the dyestuff of appropriate color as bonding agent.As the formation method of printed layers, the print process that usefulness woodburytype, silk screen print method, hectographic printing method etc. are common etc. are just passable.Particularly, carrying out polychrome printing or grayscale table now, hectographic printing method or woodburytype are suitable.In addition, in the occasion of monochrome, also can adopt coatings such as intaglio printing coating, rolling method, drop coating.
In addition, patterned layer 5 also can be metal film layer or combining by printed layers and metal film layer.Metal film layer is to be used for exhibit metallic gloss as patterned layer 5, with formation such as vacuum vapour deposition, sputtering method, ion plating method, gold-plated methods.According to the metallic glossy color of wanting to show, use metals such as aluminium, nickel, gold, platinum, chromium, iron, copper, tin, indium, silver, titanium, lead, zinc, these alloy or compound.As one of the occasion that partly forms metal film layer example, have after forming the solvent soluble resin bed on the part that does not need metal film layer, form metal film layer thereon, carry out solvent clean and come along the method for removing unwanted metal film layer with the solvent soluble resin bed.In addition,, have to form metallic film all sidedly, then form resist layer wanting to stay on the part of metallic film, carry out etching method with acid or alkali as another example.
Forming the occasion of patterned layer 5, as the printing ink that constitutes patterned layer 5, about having the character person who is adhered to shaping resin, partly (only in the scope that repeats with release layer 3) forms.Character person's (comprising the metal evaporation layer) about not being adhered to shaping resin also can form all sidedly.
In addition, as required, also can be comprehensively or back-up coat 7 partly is set in order to improve being adjacent to property between above-mentioned each transfer printing layer.Particularly, if between ionizing radiation cured layer 4 and patterned layer 5, form back-up coat 7, then can also protect formed products or patterned layer 5 not to be subjected to the evil of medicine but suitable (with reference to Fig. 3).As back-up coat 7, for example, can solidify thermoplastic resins such as heat-curing resins such as based polyurethane resin, melamine Ammonia or epoxies, vinyl chloride copolymer resin with biliquid.As the formation method of back-up coat 7, coatings such as intaglio printing coating, rolling method, drop coating are arranged, print processes such as woodburytype, silk screen print method.
Giving an example of thickness as each layer among the embodiment represents that release layer is 1 μ m, and the ionizing radiation cured layer is 5 μ m, and back-up coat is 2 μ m, and patterned layer is 3 μ m, and adhesive linkage is 2 μ m.
As previously discussed, on substrate 2, formed at least in the transfer materials 1 of banded release layer 3, ionizing radiation cured layer 4, patterned layer 5, adhesive linkage 6, transfer materials 1 is adhered to back (with reference to Figure 21) on the resin plate 144, with relative resin plate 144 is that the part place and peel strength resin plate that release layer 3 is not set was important less than 50N/m in the 1st embodiment of the present invention when 90 ° angle was peeled off.
In order to measure peel strength, at first, transfer materials 1 (be equivalent to Figure 17 and Figure 18 145) is adhered to and is transferred on the smooth resin plate 144 that thing is a same material with the roller transfer interpreter.As condition, be taken as 220 ℃ of transfer printing temperature, transfer pressure 15kN/m, transfer speed 35mm/ second.Then, flatly dispose resin plate 144 with 143 maintenances of holding devices such as chuck as shown in Figure 17, the load of peeling off when the substrate 2 (N) is measured in the end of drawing substrate 2 by the hook 142 of the load determinator 141 that kept with hand 140 on 90 ° of tops (vertical direction shown in the arrow 146) with load determinator 141.The load of measuring (N) is taken as peel strength (N/m) divided by the value of the width (m) of the substrate of peeling off 2.Moreover peel strength does not exist with ... the size of transfer materials 1, the size of resin plate 144.In addition, the environment temperature during mensuration is taken as normal temperature.
Here, be because can become constant cause to fixed angle easily with 90 ° of reasons of carrying out above-mentioned disbonded test.For example, with 30 ° or 80 ° of such angles, begin that to keep constant all the time the finish time be difficult to measuring from mensuration to angle.
As the resin plate of using in the disbonded test 144, with the resin that uses in the actual shaping, have perhaps with it similarly that the resin of character constitutes, more than the used thickness 0.5mm, the face of bonding at least transfer materials is smooth.
So, by peel strength is taken as less than 50N/m, as shown in Figure 14, when the shaping of being undertaken by injection moulding transfer printing simultaneously, even the down gate 213 of the shaping resin that is communicated in die cavity 212 be contacted with transfer materials 1 cut position 8 near occasion, also,, can carry out progressive forming so down gate 213 is peeled off easily because down gate 213 contacts with ionizing radiation cured layer 4.That is to say, as shown in Figure 15, under the injection moulding state, the part that can peel off as with transfer printing after beyond 86 the part at interface of release layer 3 of the demoulding, even can peel off because 85 part of the down gate side of shaping resin portion 150 does not have adhesive linkage 6 yet, because the part place down gate 213 this 85 can be peeled off easily, thus can be as not in the past the down gate of shaping resin deposited on adhesive linkage.Moreover, in Figure 14, the 80th, the zone that release layer 3 exists, the 81st, release layer 3 non-existent zones, the 82nd, the arrow of expression shaping resin flows.
With the transfer materials 1 of above this formation can decorated resin molded article the surface of shaping resin portion 150.Figure 15 and Figure 22 are the figure of state on surface of the both sides of the expression transfer materials 1 shaping resin portion 150 that is needed on resin forming product.As the shaping resin portion 150 of resin forming product, can be any in transparent, translucent, opaque, can be painted can be not painted yet.As resin, can enumerate resins for universal use such as propylene resin, polycarbonate resin, polystyrene resin, vistanex, acrylonitrile butadiene styrene resin, AS resin acrylonitrile styrene resin, acrylonitrile resin, polyamide.
The transfer materials 1 that just adopts above-mentioned layer to constitute utilizes transfer printing to describe in the method that is transferred the enterprising luggage decorations of object plane.At first, be transferred on the object plane, be adjacent to adhesive linkage 6 one sides of transfer materials 1.Then, with having the elastomeric roller transfer interpreter of heat resistant rubber shape such as silicone rubber, transfer interpreter such as transfer interpreter up and down, via of the substrate 2 one sides heating and pressurization of the heat resistant rubber shape elastomer of setting the condition about about 80～260 ℃ of temperature, pressure 490～1960Pa for from transfer materials 1.So, adhesive linkage 6 is adhered to and is transferred the thing surface.At last, if after cooling, peel off substrate 2, cause in the edge surface of release layer 3 and ionizing radiation cured layer 4 then and peel off that transfer printing is finished.
Next, just adopt above-mentioned transfer materials 1, being shaped simultaneously by the injection moulding utilization, transfer printing describes in the method as the enterprising luggage decorations of the face of the resin forming product that is transferred thing.At first, but transfer materials 1 is sent in the metal mould for formation of being made up of dynamic model and fixed die.At this moment, can one by one send into individual transfer materials 1, also can send into the necessary part of rectangular transfer materials 1 off and on.In the occasion of using rectangular transfer materials 1, use feeder to make the patterned layer 5 of transfer materials 1 consistent just passable with the orientation of metal mould for formation with detent mechanism.In addition, when sending into transfer materials 1 off and on, if but behind the position that detects transfer materials 1 with sensor, lean on dynamic model and fixed die stationary transfer material 1, then can be fixed in same position to transfer materials 1 all the time, owing to do not produce the location dislocation of patterned layer 5, so be easily.Behind the closed metal mould for formation, the molten resin injection is full of in the die cavity 212 (with reference to Figure 14) of metal pattern, transfer materials 1 is adhered on its face from cast gate.Cooling is opened metal mould for formation and is taken out resin forming product as after being transferred the resin forming product of thing.At last, by peeling off substrate 2, transfer printing finishes.
Above-mentioned transfer materials 1 is with regard near the part that release layer 3 is not set cutting position 8, because be to be the most surperficial formation with the low layer of the cementability of shaping resin, so also can successfully peel off down gate from the end of transfer materials 1, can not bring obstacle to progressive forming.In addition, because lamination ionizing radiation cured layer 4 all sidedly is easy so strengthen the thickness of ionizing radiation cured layer 4, can obtain having the formed products of enough surface strengths.
(embodiment 1)

With regard to the position (zone) that forms non-adhesive linkage 57,, then do not produce shaping resin and substrate 52 can not be peeled off such problem if non-adhesive linkage 57 covers the part that does not form release layer 53 fully.But even do not form the part of release layer 53, so long as when being shaped and the discontiguous position of down gate, also it doesn't matter even then do not form non-adhesive linkage 57.Thereby at least, what contact with down gate when being shaped forms non-adhesive linkage 57 with release layer 53 unduplicated positions.It must be banded that non-adhesive linkage 57 there is no need.The formation method of non-adhesive linkage 57 is not limited to coating.As the thickness of non-adhesive linkage 57,, when being shaped, do not bring any obstacle above blocked up occasions such as 1cm.As definite method of non-adhesive linkage 57, the direction dislocation when considering printing is preferably in than more than the wide 1mm of the width of the part that does not form release layer 53, than suitably determining in the scope more than the narrow 1mm of the width of the part that does not form pattern.As the method for exposing non-bonding region, form all sidedly in the middle of the adhesive linkage 56, also can in the zone that forms as non-adhesive linkage 57, form non-adhesive linkage 57 by UV, the EB bonding effects of minimizing such as (electron beams).
In addition, as required, also can back-up coat 58 be set comprehensively or partly in order to improve being adjacent to property.Particularly, if between ionizing radiation cured layer 54 and patterned layer 55, form back-up coat 58, then can protect formed products or patterned layer 55 to exempt from the evil (with reference to Fig. 9) of medicine.As back-up coat 58, for example, can use heat reactive resins such as biliquid curable polyurethane resin, melamine Ammonia or epoxies, thermoplastic resins such as vinyl chloride copolymer resin.As the formation method of back-up coat 58, coatings such as intaglio printing coating, rolling method, drop coating are arranged, print processes such as woodburytype, silk screen print method.
As previously discussed, on substrate 52, formed at least in the transfer materials 51 of banded release layer 53, ionizing radiation cured layer 54, patterned layer 55, adhesive linkage 56, after being adhered to transfer materials 51 on the resin plate 144, with relative resin plate 144 is that the part place and peel strength resin plate that release layer 53 is not set was important less than 50N/m in the 2nd embodiment of the present invention when 90 ° angle was peeled off.
In order to measure peel strength, at first, transfer materials 51 (be equivalent to Figure 17 and Figure 18 145) is adhered to and is transferred on the smooth resin plate 144 of thing same material with the roller transfer interpreter.As condition, be taken as 220 ℃ of transfer printing temperature, transfer pressure 15kN/m, transfer speed 35mm/ second.Then, flatly dispose resin plate 144 with 143 maintenances of holding devices such as chuck as shown in Figure 17, the load of peeling off when the substrate 52 (N) is measured in the end of drawing substrate 52 by the hook 142 of the load determinator 141 that kept with hand 140 on 90 ° of tops (vertical direction shown in the arrow 146) with load determinator 141.The load of measuring (N) is taken as peel strength (N/m) divided by the value of the width (m) of the substrate of peeling off 52.Moreover peel strength does not exist with ... the size of transfer materials 51, the size of resin plate 144.In addition, the environment temperature during mensuration is taken as normal temperature.
So, by peel strength is taken as less than 50N/m, as shown in Figure 14, when the shaping of being undertaken by injection moulding transfer printing simultaneously, near even the contacted occasion position 59 that cuts at the down gate 213 of the shaping resin that is communicated in die cavity 212 and transfer materials 51, also because down gate 213 with contact in non-adhesive linkage 57, so down gate 213 is peeled off easily, can carry out progressive forming.That is to say, as shown in Figure 16, under the injection moulding state, the part that can peel off as with transfer printing after beyond 88 the part at interface of release layer 53 of the demoulding, even not having adhesive linkage 56 yet, 87 part of the down gate side of shaping resin portion 150 can peel off, because can peel off easily at this 87 part place down gate 213, thus can be as not existing the down gate of shaping resin deposited on adhesive linkage.
With the transfer materials 51 of above this formation can decorated resin molded article the surface of shaping resin portion 150.As the shaping resin portion 150 of resin forming product, with the 1st embodiment be same.Figure 16 is the figure of state on surface of the both sides of the expression transfer materials 1 shaping resin portion 150 that is needed on resin forming product.
The transfer materials 51 that just adopts above-mentioned layer to constitute utilizes transfer printing to describe in the method that is transferred the enterprising luggage decorations of object plane.At first, be transferred on the object plane, be adjacent to adhesive linkage 56 1 sides of transfer materials 51.Then, with having the elastomeric roller transfer interpreter of heat resistant rubber shape such as silicone rubber, transfer interpreter such as transfer interpreter up and down, via of the substrate 52 one sides heating and pressurization of the heat resistant rubber shape elastomer of setting the condition about about 80～260 ℃ of temperature, pressure 490～1960Pa for from transfer materials 51.So, adhesive linkage 56 is adhered to and is transferred on the thing surface.At last, if after cooling, peel off substrate 52, cause in the edge surface of release layer 53 and ionizing radiation cured layer 54 then and peel off that transfer printing is finished.
Next, just adopt above-mentioned transfer materials 51, utilize the shaping while transfer printing of injection moulding to describe in method as the enterprising luggage decorations of the face of the resin forming product that is transferred thing.At first, but transfer materials 51 is sent in the metal mould for formation of being made up of dynamic model and fixed die.At this moment, can one by one send into individual transfer materials 51, also can send into the necessary part of rectangular transfer materials 51 off and on.In the occasion of using rectangular transfer materials 51, use feeder to make the patterned layer 55 of transfer materials 51 consistent just passable with the orientation of metal mould for formation with detent mechanism.In addition, when sending into transfer materials 51 off and on, but if behind the position that detects transfer materials 51 with sensor, lean on dynamic model and fixed die stationary transfer material 51, then can be fixed in same position to transfer materials 51 all the time, owing to do not produce the location dislocation of patterned layer 55, so be easily.Behind the closed metal mould for formation, the molten resin injection is full of in the metal pattern, transfer materials 51 is adhered on its face from cast gate.Cooling is opened metal mould for formation and is taken out resin forming product as after being transferred the resin forming product of thing.At last, by peeling off substrate 52, transfer printing finishes.
Above-mentioned transfer materials 51 is with regard near the part that release layer 53 is not set cutting position 59, because be to be the most surperficial formation with the low layer of the cementability of shaping resin, so also can successfully peel off down gate from the end of transfer materials 51, can not bring obstacle to progressive forming.In addition, because lamination ionizing radiation cured layer 54 all sidedly is easy so strengthen the thickness of ionizing radiation cured layer 54, can obtain having the formed products of enough surface strengths.
The present invention since by above-mentioned constitute form, so have following effect.
