Description

Method of hydraulic transfer and hydraulic-transfer goods
Technical field
The present invention relates to be suitable for to improve method of hydraulic transfer at the surface property of decorative layer that forms by the hydraulic pressure method on the goods or the protective layer that on decorative layer, forms by method of hydraulic transfer.
Background technology
Method of hydraulic transfer is a kind of like this method, the transfer film that wherein will contain the water-insoluble printed patterns that is applied on the water-solubility membrane applies in order and swims on the water surface, this transfer film in transfer printing is bathed, flow and by water-wet with goods (transfer article or want the object of pattern transferring) are immersed the water of transfer printing in bathing in the while it contact transfer film, use water pressure that the printed patterns of transfer film is transferred on the product surface to form decorative layer thus whereby.Printed patterns is under the dry pattern situation therein, require to apply activator to printed patterns with the printing ink that activates printed patterns to obtain and the identical printing ink wet condition (wherein it has adhering state) of state after printing ink has just printed.For providing wearability to the decorative layer that forms by hectographic printing pattern on product surface, weatherability (comprising solvent resistance, chemical-resistant etc.) must form transparent surface protective layer (face coat) on decorative layer.
In a kind of prior art; this sealer is formed by following mode: at the hectographic printing pattern; after product surface is removed water-solubility membrane and dried product, apply UV cured type protective coating material to decorative layer by spraying, then on UV cured type protective coating material irradiation ultraviolet radiation with the protective coating material that hardens thus.
Yet; the method that applies the protective coating material by spraying on goods makes sealer in the whole lip-deep difficulty and in addition because at the hectographic printing pattern of becoming that evenly applies of goods; apply protective layer after water washing and the dried product, cause that dirt and dust adhesion are to the decorative layer that forms by the hectographic printing pattern.In addition, owing to after goods are taken out in the zone that wherein applies the protective coating material ultraviolet ray is being shone on the protective coating material, dirt and dust tend to adhere to decorative layer, and this causes the appearance deterioration.
In another kind of prior art, a kind of method is proposed, wherein carry out the formation (referring to first piece of patent documentation) of the hydraulic-transfer and the sealer of printed patterns simultaneously.The method is a kind of like this method, wherein by at the transparent or semitransparent sealer that applies the water-insoluble resin on the water-solubility membrane with applying the water-insoluble printed layers then on the sealer and form and to contain the transfer film of matcoveredn and be transferred on the goods (wanting the object of pattern transferring) at the transfer film that will contain matcoveredn under the water pressure.
According to the method; owing to when goods contact transfer film, use sealer and the printed layers of water pressure while on transfer printing water-solubility membrane on the product surface of hydraulic-transfer; the method can be omitted in and apply after the transfer printing process and the step of the protective coating material that hardens; in first kind of routine techniques of mentioning, require this step, can avoid dust between decorative layer and sealer, to adhere to and can make the surface protection layer thickness become uneven possibility not having substantially.
Adopt this mode; can advantageously use the method; owing in the hectographic printing layer, form therefore can simplify the operation step the and outward appearance of deterioration decorative layer and sealer can not provide wearability to the printed layers surface of goods yet in addition of sealer; with physical protection thus it; this is because sealer is formed by protective agent such as butyl methacrylate or EMA; but because protective agent has low solvent resistance; when sealer contacts that various medical surfaces protective layers are dissolved to be fallen, the chemoproection that its surface protection function reduces and therefore sealer has low weatherability and difference unfriendly.
Proposed another kind of prior art, the prior art is similar to second kind of prior art, but is that with the latter's difference the surface protection layer material of second kind of prior art is by replacing (referring to patent documentation 2) by the resin of sclerosis such as ultraviolet ray.
In the third prior art; owing to will be used for sealer with the resin of sclerosis such as ultraviolet ray; it can adopt effective means physics and chemoproection decorative layer; but when recovering as described later or reproduce the adhesiveness of printed patterns; this printed patterns is the uppermost surface of transfer film, and it has some undesirable shortcomings.
More particularly; when carrying out transfer printing, activator or diluent are applied to printed patterns and are applied to the adhesiveness of the sealer (referring to the third prior art) of transfer film with recovery printed patterns and sealer; although it is common above-mentioned first in the third prior art; but because activator or diluent recover the adhesiveness of printed patterns by the organic solvent that use is included in activator or the diluent, if require the time that solvent composition wherein volatilizees fully and drying condition is thought of as process conditions and solvent composition is retained in printed patterns or the sealer and can provides poor influence to the hydraulic-transfer Products Quality.In addition, because organic solvent is released into atmosphere during operation or is sucked by human body, use the organic solvent of activation printed patterns or sealer to cause that organic air pollution or labourer's health damage becomes the problem that should solve immediately with this.
Because the inventor attempts directly applying the UV cured type coating material of this kind that is used for first kind of prior art, it also is ecological friendly coating material, they can find the interim adhering recovery of printing ink in the printed patterns of transfer film, but also finding becomes poor transfer printing when attempting running hours during hydraulic-transfer technology because the adhesiveness of printed patterns reduces it.Have been found that when using UV cured type printing ink to carry out identical trial, this printing ink comprises the ultraviolet hardening resin composite identical with UV cured type coating material, but do not comprise colouring agent, can recover the adhesiveness of printing ink in the printed patterns and can carry out transfer printing and even during transfer printing process, do not have an adhering reduction yet.
Under the situation of hydraulic-transfer, not only the printing ink in the printed patterns has the wet condition of recovery to recover the adhesiveness of printing ink, and the water that the water-solubility membrane that contains load printed patterns thereon also is transferred in the bath becomes wet, therefore require when goods are forced in the water, printed patterns and water-solubility membrane be connected to easily on the product surface with product surface around.Therefore, should be forced under water to finish up to transfer printing when the universal time coordinated goods that obtain printed patterns and water-solubility membrane wet condition with the adhesiveness that should keep also being suitable for being connected the printed patterns of printed patterns to the goods.
Inventor conjecture the difference between these result of the tests by UV cured type coating material form and difference between the forming of UV cured type printing ink causes, because these product purpose differences are although they comprise identical ultraviolet hardening resin composite.In addition, they guess that a species diversity of existence is that UV cured type coating material comprises low boiling point solvent, but UV cured type printing ink comprises less solvent usually, therefore, when UV cured type coating material is applied to printed patterns, the initial adherence of printed patterns can be recovered by the solvent in the coating material, but when carrying out transfer printing because the evaporation cohesive of solvent will reduce and because UV cured type printing ink does not contain solvent, any solvent-free composite all will can be used for recovering printed patterns.Carry out the present invention by under above-mentioned inferring, repeating various tests.
Imagination contains the method for transfer film transfer surface protective layer on goods of sealer by use under water pressure, form the transfer film that this contains sealer by applying on water-solubility membrane with desiccated surface protective agent such as protective coating material or ultraviolet hardening resin composite.Yet; also being difficult to thus, method of hydraulic transfer formation has wearability; the sealer of all excellent properties of hear resistance and resistance rerum natura and in the time should recovering the adhesiveness of sealer takes place and the identical problem of method of passing through hectographic printing pattern decorative goods on goods.

Water-solubility membrane 14 forms by containing the water-soluble material as main component of polyvinyl alcohol for example, and it becomes wet and by absorbing water softening.This water-solubility membrane 14 is when it reels around the softening and goods 10 that will decorate when water during transfer printing is bathed contact, so can finish hydraulic-transfer.Under the situation of common hydraulic-transfer, printed patterns 12 can be applied on the water-solubility membrane 14 by intaglio printing etc.The meaning that it should be noted that " printed patterns " 12 expression is removed and is comprised the printed patterns (printed patterns that does not contain pattern) that also comprises the plane the initial printed patterns that just has a pattern.
The method of first kind of form will apply or apply the ultraviolet hardening resin composite to the printed patterns 12 of transfer film 16 according to the present invention, to permeate printed patterns 12 before hectographic printing pattern on the goods under water pressure.Although in the embodiment of the following stated, UV cured type coating material can be used as the ultraviolet hardening resin composite, can use UV cured type printing ink.The example of the concrete steps of method of hydraulic transfer of the present invention illustrates in Fig. 2.In the form of Fig. 2, operation is in the state (referring to Fig. 2 A) of drying condition from wherein being printed on printed patterns 12 on the water-solubility membrane 14.Although do not show, in fact, the form of transfer film 16 is the volume by before printing printed patterns 12 and dry printed patterns 12 obtain on the water-solubility membrane 14 of elongation.Transfer film 16 can used from the continuous feed of film roller or by cutting it thereafter.
In the form of Fig. 2, UV cured type coating material 20 is applied on the dry printed patterns 12 of transfer film 16 of Fig. 2 A (referring to Fig. 2 B), therefore printed patterns 12 is recovered under the adhering state of printed patterns 12 by UV cured type coating material 20 activation therein, float on the water 18 of transfer film 16 in transfer printing is bathed (referring to Fig. 2 C), goods 10 with transfer film 16 forced enter under water thereafter, face toward the surperficial 10S (referring to Fig. 2 D) of goods and irradiation ultraviolet radiation 22 on goods 10 with the printed patterns of forcing to comprise UV cured type coating material 20 12, transfer printing has the printed patterns 12 that comprises UV cured type coating material 20 on goods 10, and UV cured type coating material 20 (referring to Fig. 2 E) therefore hardens.Although show in the accompanying drawings, can when supporting by anti-triangular shape conveyer conveying or by the robots arm, goods 10 force goods 10 to enter under water.In some cases, on printed patterns 12, apply the step (referring to Fig. 2 B) of UV cured type coating material 20 and the step (referring to Fig. 2 C) of the transfer film 16 that floats on the water can be carried out on the contrary, therefore can UV cured type coating material 20 be applied on the printed patterns that swims in transfer film waterborne 16 by spraying, to recover the adhesiveness of printed patterns 12.
UV cured type coating material 20 is that the ultraviolet hardening resin composite and this material that are used for activating suitably the dry printed patterns 12 of transfer film 16 can comprise the composition with following composition.
(1) oligomer 30-50wt%
(2) polyfunctional acrylic ester 10-30wt%
(3) monofunctional acrylate 10-40wt%
(4) non-reacted additive 1-20wt%
(5) Photoepolymerizationinitiater initiater 0.5-5wt%
(6) solvent surplus
Oligomer is to influence the composition of the adhesiveness of coating material and physical property and can use a kind of use of acrylic compounds oligomer, polyester oligomer, epoxy acrylate oligomer and urethane acrylate oligomer separately or they can at random be used in combination according to required characteristic.
Monofunctional acrylate monomer is that the function of reactant diluent and this material is that the dry printed patterns 12 of activation is to recover its adhesiveness.It is to adopt the mode identical with monofunctional acrylate monomer to activate the printed patterns 12 of drying to recover its adhesiveness with the other function that provides weatherability and intensity to printed patterns 12 and have that the polyfunctional acrylic ester monomer is into bridge composition and the characteristic of giving chemistry and mechanics excellence to coating material after it UV cured.
Use polyacrylate such as PMA etc. to alleviate contraction by the coating that becomes the bridge composition to cause.If the convergent force of coating uprises, the adhesiveness of coating descends, and then polyacrylate can usefully be prevented situation here.
Conventional acetophenone, benzophenone etc. can be used as solvent as Photoepolymerizationinitiater initiater and ethyl acetate, butyl acetate, acetate propylene glycol monomethyl alcohol ester, cyclohexanone (cyclohexanone), toluene, dimethylbenzene etc.
Although applying the step of UV cured type coating material 20 can apply and any of spraying carries out by photogravure roller, coiling rod, because spraying applies a large amount of coating materials of processes expend, therefore preferably the photogravure roller applies technology or the rod that winds the line applies technology and is used to apply coating material.
When being applied to UV cured type coating material 20 on the printed patterns 12, dry printed patterns 12 by the monofunctional acrylate monomer in the UV cured type coating material 20 or the activation of polyfunctional acrylic ester monomer and in addition under possible situation by activation such as solvents, therefore recover the adhesiveness of printing ink.Therefore, UV cured type coating material 20 can have with the activator identical functions that applies usually on dry printing ink so omit applying of activator.
When being applied to UV cured type coating material 20 on the printed patterns 12, the coating material composition infiltrates through printed patterns 12 and therefore ink composition and coating material composition are mixed with each other with The combined.Therefore, when irradiation ultraviolet radiation 22 is with the cured coating material composition when be transferred to goods 10 at the printed patterns 12 that the coating material composition is mixed with it after, will give printed patterns 12 mechanical strength and chemical characteristic such as hear resistance and weatherability.Although Fig. 2 B and 2C do not illustrate the wherein ink composition of printed patterns 12 and the state that UV cured type coating material is united fully, if these figure attempt showing such state, then can not to be distinguished from each other both, but to be to be understood that in order conveniently being that state with layer shows them.
Ultraviolet ray 22 is shone contain the goods of the printed patterns 20 of its transfer printing on after, water spray 24 is ejected on the water-solubility membrane 14 of transfer film 16 with therefore washings soluble film 14, shown in Fig. 2 F, therefore water-solubility membrane 14 is removed from the surface of goods 10., as Fig. 2 G shown in, hot blast 26 be radiated at the surface of goods 10 on, on goods 10, be stained with the printed patterns 12 that comprises UV cured type coating material 20,, therefore finish 10 ' (with reference to the figure 3) that contains decorative layer 30 with the surface of dried product 10 thereafter.
Preferably at the water-solubility membrane 14 of transfer film 16 irradiation ultraviolet radiation 22 when reeling around the goods 10, transfer printing comprises the printed patterns 12 of UV cured type coating material 20 on goods 10, although therefore preferably goods 10 still under water after or it from water, come out to shine in water washing with before removing water-solubility membrane 14.Ultraviolet ray 22 is by conventional ultraviolet curing equipment irradiation, and this equipment comprises illuminator such as high-pressure sodium lamp or metal halide lamp and irradiating machine (lamp house).Because ultraviolet ray can penetrate under water, so can when goods 10 are underwater, ultraviolet ray 22 be shone on the goods 10.
Adopt this mode, irradiation ultraviolet radiation 22 when water-solubility membrane 14 is wound on around the goods, thereby any dirt etc. can not adhere on the goods before printed patterns 12 bone dries, can reduce the possibility that dirt adheres to, this is owing to printed patterns 12 when removing water-solubility membrane 14 has hardened, and therefore can easily obtain to have the decorative layer 30 of good appearance.In environment that does not contain dust or dirt such as tunnel-like clean room, carry out therein under the situation of ultraviolet ray 22 irradiation, can be in the irradiation of water-solubility membrane 14 being carried out ultraviolet 22 from goods 10 water washings are fallen after.
(embodiment 1)
In the specific embodiments of first kind of form according to the present invention, formation is available from FUJIKURA KASEI CO., LTD., the material of Ri Ben FUJIHARD HH9986 U-N7 main component carries out technology as UV cured type coating material 20 and employing Fig. 2 A to the order of step shown in the 2G.Just transfer film 16 is introduced before the transfer printing bath shortly, applies technology by photogravure UV cured type coating material 20 is applied or is coated on the printed patterns 12 of transfer film 16.Adopt this mode, float on the water surface of bathing as Fig. 2 transfer printing that D the is shown in transfer film 16 that applies coating material thereon and after activating printed patterns 12 with UV cured type coating material 20 and recovering enough adhesiveness pushes goods 10 under water by transfer film 16.After after transfer printing, goods 10 being taken out from water, irradiation ultraviolet radiation on goods, thereafter with goods water cleaning and dry with obtain hydraulic-transfer goods 10 shown in Figure 3 '.
When the decorative layer of the hydraulic-transfer goods (A) that obtain like this by cross cutting belt adhesiveness method of testing (1mm otch measure 100 times) test, confirm that goods (A) have with the hydraulic-transfer goods (B) that do not contain face coat and contain the identical adhesiveness of hydraulic-transfer goods (C) of the conventional acrylic resin face coat that applies on decorative layer.On the goods under predetermined load by carrying out the test of solvent resistance 30 times with the reciprocal wiping of rag that comprises isopropyl alcohol, confirm that the solvent resistance of hydraulic-transfer goods (A) significantly is better than the conventional hydraulic-transfer goods (C) that contain face coat.Certainly, the hydraulic-transfer goods (B) that do not contain face coat do not have solvent resistance.Therefore, notice that the hydraulic-transfer goods of first kind of form have weatherability and have high mechanical strength according to embodiments of the present invention, these performances are realized by the UV cured type coating material that infiltrates through decorative layer.
In first kind of form of embodiment shown in Figure 2, the transfer film 16 that use contains dry printed patterns 12 carries out transfer operation, but in second kind of form of embodiment shown in Figure 4, transfer operation can be undertaken by following mode: apply or apply UV cured type coating material 20 to water-solubility membrane 14, printing printed patterns 12 by off-contact printing mode such as ink-jet system on the coating material 20 and before printed patterns 12 dryings transfer film 16 is being introduced transfer printings and bathe thereafter.
In the case, because the ink composition of printed patterns 12 has kept adhesiveness, do not have the function of activation printing ink so require UV cured type coating material 20, but by printing printed patterns 12 on coating material 20, coating material 20 infiltrates through ink composition, therefore UV cured type coating material 20 and ink composition adopt with the identic mode of Fig. 2 embodiment and unite fully, so the decorative layer of hydraulic-transfer goods has the identic characteristic with Fig. 3.
First kind and second kind of form according to embodiments of the present invention; since therein on the printed patterns 12 of transfer film 16 or under apply the hydraulic-transfer that carries out goods 10 surfaces under the state of UV cured type coating material 20; so on product surface transfer printing simultaneously printed patterns 12 and ultraviolet hardening resin composite; can notice not require the operation that applies sealer at the decorative layer that forms by printed patterns 12, so the later stage technology of hydraulic-transfer obtains simplifying.
Because UV cured type coating material 20 has mobilizing function to recover the adhesiveness of dry printed patterns 12, do not require independent operation adopting activator activation printed patterns 12, so the overall craft of hydraulic-transfer and possible later stage technology become simpler.
Since therein UV cured type coating material 20 infiltrate through printed patterns 12 inner and with state that printed patterns 12 mixes under; by UV cured type coating material 20, thus to the decorative layer self of goods given the surface protection effect and therefore printed patterns 12 have machinery and the excellent surface property of chemistry.
Even since under water or goods from water, come out in water washing and carry out the step of irradiation ultraviolet radiation before removing water-solubility membrane, dust, dirt etc. adhere to less than on the printed patterns 12, so can obtain the decorative layer of good appearance.
Even UV cured type coating material 20 can be replaced also can reaching identical effect by the UV cured type printing ink of having described.
In Fig. 5, show the method for hydraulic transfer of the third form (forming the method for sealer) according to embodiments of the present invention.Although the method typically is applied in by this hydraulic-transfer of Fig. 2 and decorates on the product surface afterwards, with the surface of protection decorated articles 10, certain the method for the present invention also can similarly be used on the product surface of being decorated by other appropriate action.
In the method for the present invention; as shown in Figure 5; the initial sealer transfer film 216 that contains UV cured type sealer 240 that forms forms UV cured type sealer 240 (referring to Fig. 5 A) by apply UV cured type protective agent (ultraviolet hardening resin composite) on water-solubility membrane 214.As the water-solubility membrane 14 of the transfer film 16 that is used for first kind of form of embodiment, water-solubility membrane 214 can comprise water-soluble material, and this water-soluble material contains for example main component of polyvinyl alcohol, and it becomes wet and softening by absorbing water.
Under the situation of goods 10 by decorations such as hydraulic-transfers; UV cured type protective agent is that UV cured type clear dope material and this coating material can comprise the composition with following composition; with because this is identical composition with the UV cured type coating material that is used for first kind and second kind form of embodiment, so omission detailed description.
(1) oligomer 30-50wt%
(2) polyfunctional acrylic ester 10-30wt%
(3) monofunctional acrylate 10-40wt%
(4) non-reacted additive 1-20wt%
(5) Photoepolymerizationinitiater initiater 0.5-5wt%
(6) solvent surplus
Adopt this mode, after forming sealer transfer film 216, float on the surface of the water 218 of this transfer film 216 in transfer printing is bathed and sealer 240 directions towards (referring to Fig. 5 B).When the water-solubility membrane 214 of transfer film 216 was become wet fully by water 218, the goods 10 that will contain the surface that will protect forced to enter the hydraulic-transfer (referring to Fig. 5 C and 5D) to carry out UV cured type sealer 240 on goods 10 in the water 218 by sealer transfer film 216.
Thereafter, on the UV cured type sealer 240 that is transferred on the goods 10 irradiation ultraviolet radiation 222 with hardened surface protective layer 240 (referring to Fig. 5 E).Remove water-solubility membrane 214 (referring to Fig. 5 F) to the surface of goods 10 by spray washing water 224.At last, hot blast 226 is blown on the surface of goods 10 with dry it (referring to Fig. 5 G), therefore finish product 210 ' (referring to Fig. 6) by sealer 240 ' protection.In Fig. 5 D and 5E,, do not indicate the water-solubility membrane 214 and the sealer 240 of transfer film 216 although they are distinguished each other.
As the hydraulic-transfer that Fig. 2 is used to decorate, wish to be wound on goods 10 carry out ultraviolet ray 220 on every side irradiation at the water-solubility membrane 214 of transfer film 216.This can harden UV cured type coating material and do not adhere to dust, dirt wait until the sealer 240 of UV cured type coating material and therefore can form the sealer with good appearance 240 that do not contain the dust that adheres on it, dirt etc. '.
(embodiment 2)
In the specific embodiments of the third form according to the present invention, formation is available from FUJIKURA KASEI CO., LTD., the material of Ri Ben FUJIHARD HH9986 U-N7 main component carries out this technology as UV cured type clear dope material and employing Fig. 5 A to the sequence of steps shown in the 5F.Before being about to be introduced into the transfer printing bath, transfer film on water-solubility membrane 16, applies UV cured type clear dope material by photogravure technology.Adopt this mode, contain and swim on the water surface that transfer printing bathes and sealer is directed upwardly and thereafter goods is pushed under water by transfer film by the transfer film that applies the sealer that coating material forms.Behind the transfer surface protective layer goods are being taken out from water on the product surface; irradiation ultraviolet radiation on sealer; at last goods are washed with water and dry with the product 210 that obtains to contain the UV cured sealer 214 ' that forms thereon ', as shown in Figure 6.
When by cross cutting belt adhesiveness method of testing (1mm otch measure 100 times) test during, confirm that goods (D) have with the hydraulic-transfer goods (B) that do not contain face coat and contain the identical adhesiveness of hydraulic-transfer goods (C) of the conventional acrylic resin that applies on decorative layer by the adhesiveness of hydraulic-transfer goods (product) sealer (D) of the transparent surface protective layer protection of such acquisition.On the goods under predetermined load by carrying out the test of solvent resistance 30 times with the reciprocal wiping of rag that comprises isopropyl alcohol, confirm that the solvent resistance of hydraulic-transfer goods (D) significantly is better than the conventional hydraulic-transfer goods (C) that contain the face coat that forms thereon.Certainly, the hydraulic-transfer goods (B) that do not contain face coat do not have solvent resistance.Therefore, notice that the hydraulic-transfer goods according to specific embodiments of the present invention have good weatherability and have high mechanical strength, these performances are realized by UV cured type coating material.
In the above-mentioned form of embodiment; although the clear dope material is used as UV cured type protective agent, can use translucent coating material and the goods can be by decorating by the sealer self that uses UV cured type printing ink rather than coating material to form.Adopt this mode, if use UV cured type printing ink, then sealer causes having decoration and two kinds of functions of surface protection.
As shown in Figure 7; on water-solubility membrane 214, apply UV cured type protective agent with after the formation sealer 240, can in sealer 240, be processed to form suitable relief pattern 240a such as particle pattern and other pattern by relief pattern processing or explosion.
In Fig. 8, show the method for hydraulic transfer of the 4th kind of form according to embodiments of the present invention.The method is with identical according to the method for first kind of form of embodiment, except will not being UV cured type coating material 20 at the material that applies or apply on the printed patterns 12 of transfer film 16 but can adopting the mode identical with first kind of mode of embodiment to carry out (referring to Fig. 8 A to 8G) with this no-solvent type ultraviolet hardening resin composite 20A.
The resin that " ultraviolet hardening resin " expression is hardened by the relative shorter time of ultraviolet chemical action effect and take forms such as UV cured type coating material, UV cured type printing ink, UV cured type adhesive according to its purposes.These reagent comprise (1) photopolymerization prepolymer as indispensable composition, (2) photo polymerization monomer and (3) light (optics) initator.Contain solvent such as the alcohol that joins wherein although on market, contain solvent usually as diluent and some the UV cured printing ink that join wherein as the material that is used for the UV cured type coating material of first kind of form of embodiment of the present invention, common UV cured type printing ink do not contain the solvent that joins wherein and with the photo polymerization monomer blend with as diluent." ultraviolet hardening resin composite ", it is the purpose of the 4th kind of form of embodiment of the present invention, substantially with photopolymerization prepolymer, photo polymerization monomer and Photoepolymerizationinitiater initiater blend no matter the type of service of ultraviolet hardening resin and do not add any solvent and before by ultraviolet ray irradiation sclerosis, also have liquid form.
Material by " ultraviolet hardening resin composite " expression that will be used for the 4th kind of form of embodiment of the present invention is got rid of the solvent-free ultraviolet hardening resin composite that wherein comprises the ultraviolet hardening resin composite of solvent and be limited to the solvent that does not contain adding.This is that it is photo polymerization monomer typically because to recover the printed patterns of transfer film adhering be solvent-free activating component in the no-solvent type ultraviolet hardening resin composite.The ultraviolet hardening resin composite that is applicable to the 4th kind of form of embodiment of the present invention comprises the composition with following composition;
(1) oligomer (photopolymerization prepolymer) 30-50wt%
(2) polyfunctional acrylic ester
(photo polymerization monomer) 10-30wt%
(3) monofunctional acrylate
(photo polymerization monomer) 10-40wt%
(4) Photoepolymerizationinitiater initiater 0.5-5wt%
(5) non-reacted additive 1-20wt%
The photopolymerization prepolymer be can be further by the polymer of photochemical effect sclerosis and be called as " photopolymerization unsaturated polymer ", " base resin " or " photopolymerization oligomer.As this prepolymer of coat film after the sclerosis is that basic ingredient and acrylic compounds oligomer, polyester oligomer, epoxy acrylate oligomer and the urethane acrylate oligomer that influences many important physical properties can independently or arbitrarily be used in combination.Although the degree of polymerization of photopolymerization prepolymer is not as final polymerization object height, it is not monomer and has been aggregated to certain degree therefore it has suitable viscosity and therefore considers the operating effect when it uses and require to use diluent.
Photo polymerization monomer keeps the actual effect of resin composite materials operation simultaneously and self participates in polymerization as the diluent of photopolymerization prepolymer.There are monofunctional monomer that contains single functional group and the polyfunctional monomer that contains two or more functional groups.Monofunctional monomer is used to improve gives flexibility with the coat film after sclerosis and polyfunctional monomer is used as bridge joint prepolymer molecule becomes the bridge agent to the adhesiveness of goods.For example, polyacrylate such as PMA are used to alleviate the contraction by the coat film that becomes bridge to cause.If the convergent force of coat film uprises, the adhesiveness of coat film will be reduced, but polyacrylate can usefully be prevented situation here.These photo polymerization monomers are as the diluent of regulating ultraviolet hardening resin composite viscosity and also as the adhering functional component (activating component) of recovering dry printed patterns.
Photoepolymerizationinitiater initiater is used for absorbing ultraviolet ray with initiated polymerization be also referred to as " Photoepolymerizationinitiater initiater ".Acetophenone, benzophenone etc. can be used when UV cured reaction is radical reaction, and when UV cured reaction is ionic reaction, diazonium compound etc. can be used.
The ultraviolet hardening resin composite can contain the sensitizer of oriented its adding, filler, nonactive organic polymer, levelling agent, thixotropy imparting agent, thermal polymerization inhibitor etc.
When being applied to no-solvent type ultraviolet hardening resin composite 20A on the printed patterns 12, photo polymerization monomer among the no-solvent type ultraviolet hardening resin composite 20A infiltrates through the dry printing ink of printed patterns 12 with dissolving printing ink, therefore can recover the adhesiveness of printing ink, this printing ink has and just prints printed patterns identical wet condition afterwards.Therefore, no-solvent type ultraviolet hardening resin composite 20A can have the function that is equal to normally used activator, with therefore omit activator, diluent etc. apply and since the volatility that comprises every kind of composition in the ultraviolet hardening resin composite of photo polymerization monomer usually far below solvent etc., the degree of adhesion of recovering after adhesiveness is recovered neither changes also and does not descend, this can realize activating stable expectation, can not realize in solvent-borne type and activation is stable.
When with printed patterns 12 transfer printings on goods 10 and thereon during irradiation ultraviolet radiation 22, the every kind of composition of ultraviolet hardening resin composite 20A such as photo polymerization monomer infiltrate through under the state of printing ink of printed patterns 12 therein, sclerosis ultraviolet hardening resin composite, so ultraviolet hardening resin composite and printing ink are united fully.This gives mechanical surface defencive function such as wearability etc. and chemical surface defencive function such as solvent resistance to decorative layer self, resistance rerum natura etc.This form of implementation also has those function identical functions with first kind of form of embodiment.Because photo polymerization monomer self participates in polymerization after the ultraviolet ray irradiation, this monomer never separates therefore not have a negative impact after it.
As mentioned above; the ultraviolet hardening resin composite that contains the oriented solvent that wherein adds all self is given the surface protection function to printed patterns 12 usually as commercially available general ultraviolet line constrictive type coating material that is used for first kind of form of embodiment and the no-solvent type ultraviolet hardening resin composite that is used for the 4th kind of form of embodiment; because these composites and printed patterns are united fully, but owing to following reason no-solvent type ultraviolet hardening resin composite more is better than containing the oriented wherein ultraviolet hardening resin composite of the solvent of adding.
Because ultraviolet hardening resin is hardened by ultraviolet short irradiation, if the solvent that adds is to have high-volatile low boiling point solvent, then solvent is waved evaporation fully therefore to provide poor transfer printing owing to lacking adhesiveness before goods are forced to enter under water, if and the solvent that adds is the high boiling solvent that is difficult to volatilize, can avoid adhering shortage when goods are forced under water, but after volatilizing fully, solvent just can carry out the ultraviolet ray irradiation, if and under the state of the insufficient volatilization of solvent, shine sclerosis uv-hardening resin composition by ultraviolet ray, described resinous principle is in the state that wherein relates to solvent, can produce the defective as surface roughness later on.Therefore, if use the ultraviolet hardening resin composite contain the oriented solvent that wherein adds, this solvent is a low boiling or high boiling, exists because the health damage that air pollution or absorption of human body cause and technology or quality are produced the possibility of variety of issue.
On the other hand, as part explanation, if use no-solvent type ultraviolet hardening resin composite, because photo polymerization monomer also can be regulated the diluent of purpose as the viscosity degree, so compare the solvent-free ultraviolet hardening resin composite that can prepare greater number with the type that comprises solvent.This only makes it possible to realize abundant and stable adhering recovery by the effect of solvent-free activating component in the no-solvent type ultraviolet hardening resin composite that this composition is photo polymerization monomer typically.In addition, because ultraviolet hardening resin composite 20A and printed patterns 12 is united each other fully and sclerosis and functional equivalent participate in polymerization in the photo polymerization monomer self of normally used solvent is so this photo polymerization monomer never separates therefore not have a negative impact after it.
In the 5th kind of form of embodiment of the present invention, on decorative layer, form UV-cured resin surface coating by the method for using Figure 10, obtain these decorative layers so that apply this decorative layer again by the printed patterns 12 that ultraviolet hardening resin composite 20A activates by transfer printing under water pressure by the hydraulic-transfer of independent operation.The transfer film 116 that contains transparent, UV hardening resin composite 120A by use hydraulic-transfer thus carries out the operation that face coat applies, on the whole surface at plane water-solubility membrane 114 under the single color state (non-pattern state), apply composite 120A and form transfer film 116, as shown in figure 10.This transfer film 116 and becoming suitably when water-solubility membrane 114 when wetting floating on the water surface immediately after the applying of ultraviolet hardening resin composite 120A, and pressure contains goods 10 to its decorative layer that applies ' enter in the water 118.Thereafter, carry out the ultraviolet ray irradiation as the step of Fig. 8 E and figure subsequently, water washing and drying, they are undertaken by the window dressing operation of hydraulic-transfer, therefore obtain to contain the hydraulic-transfer product 110 of face coat ', by forming this face coat (referring to Figure 11) by ultraviolet hardening resin face coat 130 outer coatings.
Can be used for the operation that the face coat of hydraulic-transfer applies by the transfer film that use contains the ultraviolet hardening resin composite, form this transfer film by sclerosis in advance, thereby after on plane water-solubility membrane 14, applying the ultraviolet hardening resin composite, do not cause adhesion rather than promptly will before this transfer film that floats on the water surface, apply the ultraviolet hardening resin composite with single color state with single color state (non-pattern state).In the case, before swimming in transfer film on the water surface, no-solvent type ultraviolet hardening resin composite or photo polymerization monomer composition can be applied to monochrome on the ultraviolet hardening resin composite that hardens in advance of transfer film, therefore to recover the adhesiveness of ultraviolet hardening resin and can press the operation of transfer printing to carry out the step of Fig. 8 C and figure subsequently as decorative water then.
Adopt this mode on decorative layer 30, to apply face coat 130, given the degree of depth and in addition, further improve the machinery and the chemical surface protection of decorative layer 30 to the outward appearance of decorative layer 30.
By using no-solvent type ultraviolet hardening resin composite, the 4th kind of embodiment of the present invention and the 5th kind of form can obtain various advantages.Do not mean that by the term " no-solvent type " in the no-solvent type ultraviolet hardening resin composite of the present invention's use " solvent composition " definitely is zero, but never get rid of the solvent composition contain adding to avoid the present invention or to contain the type of the solvent composition that is useful on manufacture order body or prepolymer, but condition is can be by the solvent-free activating component in the ultraviolet hardening resin composite, this solvent-free activating component is photo polymerization monomer typically, the adhesion function again that obtains printed patterns to must and degree completely.Similarly, term " no-solvent type " does not mean that photo polymerization monomer " volatility " definitely is zero, but mean volatility be not so good as solvent high and therefore the volatility degree that has of photo polymerization monomer in fact can not consider.In addition, although be to be understood that operation claimed apparatus and the equipment investment or the security control of hydraulic-transfer, the notion of ultraviolet hardening resin composite can comprise electron ray hardening resin composite, this is because of comprising photopolymerization prepolymer and the photo polymerization monomer electron ray hardening resin composite as neccessary composition, it can omit Photoepolymerizationinitiater initiater by more high-octane electron ray of irradiation and sclerosis on resin composite materials, the function and the photo polymerization monomer self that have by the photo polymerization monomer activation participate in polymerization, work as the initial ultraviolet hardening resin composite that comprises Photoepolymerizationinitiater initiater.
