Description

本発明は、インモールド用転写箔に関し、さらに詳しくは、工業製品の加飾に適したインモールド用転写箔に関する。   The present invention relates to an in-mold transfer foil, and more particularly to an in-mold transfer foil suitable for decorating industrial products.

インモールド用転写箔を用いた成形品は、日用品や生活用品などの機器本体、食品や各種物品の容器類、電子機器や事務用品などの筐体類などに用いられる。   Molded articles using the in-mold transfer foil are used in equipment bodies such as daily necessities and daily necessities, containers for food and various articles, and housings such as electronic equipment and office supplies.

インモールド用転写箔とは、基材となるベースフィルム上に、たとえば、剥離層、印刷層、接着層を形成したプラスチック加飾成形用の転写箔である。インモールド成形は、一対の射出成形用金型間に該転写箔を供給し、該射出成形用金型によって形成されるキャビティに加熱加圧した成形樹脂を充填後、ベースフィルム及び剥離層を剥離して、成形樹脂に印刷層を転写して装飾を行う成形方法である。   The in-mold transfer foil is a transfer foil for plastic decorative molding in which, for example, a release layer, a print layer, and an adhesive layer are formed on a base film serving as a base material. In-mold molding supplies the transfer foil between a pair of injection molds, fills the cavity formed by the injection mold with heat-pressed molding resin, and then peels the base film and release layer. Then, the molding method is to perform decoration by transferring the printing layer to the molding resin.

表面強度の高い成形品を得るためのインモールド用転写箔としては、剥離層の表面上に紫外線硬化性樹脂からなるハードコート層を形成し、さらにその上に印刷層、接着層などを形成したものがある。この場合、成形前のインモールド用転写箔に紫外線を照射し、ハードコート層を硬化させてしまうと、成形性が損なわれることから、成形後に成形品に紫外線を照射し、ハードコート層を硬化させることが望ましい。   As a transfer foil for in-mold to obtain a molded product with high surface strength, a hard coat layer made of an ultraviolet curable resin was formed on the surface of the release layer, and a printed layer, an adhesive layer, etc. were further formed thereon. There is something. In this case, if the hard coat layer is cured by irradiating the in-mold transfer foil before molding, the moldability will be lost. It is desirable to make it.

従来のインモールド用転写箔は、文字や絵柄等をベースフィルム上に平面的に印刷しただけの構造であるため、成形品表面の立体感が乏しいという問題があった。成形品表面に立体感を持たせる方法として、成形時にキャビティを構成する一対の射出成形用金型の内側のベースフィルムが対接する側に、予め凹凸を設けておく方法がある。しかし、このような凹凸形成方法では、1つの射出成形用金型に対して、1つの凹凸模様にしか対応できず、多様な凹凸模様に対応するには、多数の射出成形用金型を用意しなければならず、コストが高くなるといった問題が生じる。また、インモールド用転写箔の供給位置によって凹凸模様位置が決まるので、インモールド用転写箔の絵柄と凹凸模様を対応させることが難しい。   Since the conventional in-mold transfer foil has a structure in which characters, pictures, and the like are simply printed on a base film in a flat manner, there is a problem that the three-dimensional effect on the surface of the molded product is poor. As a method of giving a three-dimensional feeling to the surface of a molded product, there is a method of providing unevenness in advance on the side where the base film inside a pair of injection molds that constitute a cavity at the time of molding contacts. However, with such a method for forming irregularities, only one irregularity pattern can be supported for one injection mold, and a large number of injection molds are available to accommodate various irregularities. This has the problem of increasing costs. In addition, since the position of the concavo-convex pattern is determined by the supply position of the in-mold transfer foil, it is difficult to match the pattern of the in-mold transfer foil with the concavo-convex pattern.

そこで、成形品表面に凹凸を形成する方法として、ベースフィルムの一方の面に、剥離層、印刷層、該印刷層を成形品の表面に接着させるための接着層を備えると共に、上記ベースフィルムのもう一方の面に、印刷による凹凸形成層を設けるといった方法がある(例えば、特許文献１参照)。   Therefore, as a method of forming irregularities on the surface of the molded product, a release layer, a printed layer, and an adhesive layer for bonding the printed layer to the surface of the molded product are provided on one surface of the base film. There is a method of providing a concavo-convex formation layer by printing on the other surface (see, for example, Patent Document 1).

特開平１−１２０３９８号公報JP-A-1-120398

工業製品は長期にわたる使用や、過酷な環境での使用が予想されるため、工業製品の加飾に用いるインモールド用転写箔には転写後の成形品の表面強度の高い転写箔が求められる。そこで、剥離層の上にハードコート層を形成し、さらにその上に印刷層、接着層などを形成したインモールド用転写箔を、工業製品の加飾に用いることが望ましい。しかし、インモールド用転写箔で用いられるハードコート層の多くは、紫外線硬化性樹脂から形成されるため、紫外線硬化性樹脂を用いて凹凸形成層を設けると、成形前にインモールド用
転写箔に紫外線を照射しなければならず、成形前に紫外線硬化性樹脂からなるハードコート層を硬化させてしまう。それにより、インモールド用転写箔の成形性が損なわれ、不良品が発生しやすいといった問題が生じる。 Since industrial products are expected to be used for a long time or in harsh environments, transfer foils for in-mold used for decorating industrial products are required to have transfer foils with high surface strength of the molded product after transfer. Therefore, it is desirable to use an in-mold transfer foil in which a hard coat layer is formed on a release layer and a printed layer, an adhesive layer, and the like are further formed thereon for decorating industrial products. However, since most of the hard coat layers used in in-mold transfer foils are formed from an ultraviolet curable resin, if an unevenness forming layer is provided using an ultraviolet curable resin, the in-mold transfer foil is formed before molding. Ultraviolet rays must be irradiated, and the hard coat layer made of an ultraviolet curable resin is cured before molding. Thereby, the moldability of the in-mold transfer foil is impaired, and a problem that defective products are likely to occur occurs.

本発明は、このような問題点を解決しようとするものであり、成形品表面に凹凸を形成しつつ、且つ、高い表面強度を有する成形品を提供することの出来る転写箔と成形品を提案することを目的とする。   The present invention is intended to solve such problems, and proposes a transfer foil and a molded product that can provide a molded product having high surface strength while forming irregularities on the surface of the molded product. The purpose is to do.

上記課題を解決するために、本発明の請求項１の発明は、ベースフィルムの一方の面に、剥離層と、紫外線硬化性樹脂を含むハードコート層と、所定の絵柄パターンを有する印刷層と、該印刷層を成形品の表面に接着させるための接着層とをこの順序で備え、ベースフィルムのもう一方の面に、熱硬化性樹脂からなる凹凸形成層が設けられており、前記ベースフィルムの一方の面に、前記剥離層と、前記ハードコート層と、前記印刷層と、前記接着層と、をこの順で積層する印刷工程と、前記印刷工程の後に、前記ベースフィルムのもう一方の面に、前記凹凸形成層を設ける工程と、を具備し、前記ハードコート層は、紫外線照射による硬化反応が完結していない未硬化の状態で形成されており、前記凹凸形成層は、コート法もしくは印刷法により設けられた前記熱硬化性樹脂をエンボス加工することで形成されていることを特徴とするインモールド用転写箔の製造方法である。

In order to solve the above-mentioned problems, the invention of claim 1 of the present invention is characterized in that on one surface of a base film, a release layer, a hard coat layer containing an ultraviolet curable resin, and a print layer having a predetermined pattern pattern And an adhesive layer for adhering the printed layer to the surface of the molded product in this order, and the base film is provided with a concavo-convex forming layer made of a thermosetting resin on the other surface of the base film. A printing step of laminating the release layer, the hard coat layer, the printing layer, and the adhesive layer in this order on one side of the substrate, and after the printing step, the other side of the base film Providing the unevenness forming layer on the surface, and the hard coat layer is formed in an uncured state in which a curing reaction by ultraviolet irradiation is not completed, and the unevenness forming layer is formed by a coating method. Or printing method A method for producing a transfer foil for in-mold, characterized in that the more the thermosetting resin provided is formed by embossing.

請求項２の発明は、請求項１に記載のインモールド用転写箔の製造方法により得られる転写箔を用いて、インモールド射出成形を行なった後、成形品の表面に紫外線を照射することで前記ハードコート層を完全硬化させる工程を具備することを特徴とする成形品の製造方法である。 Of inventions the claims 2, using the transfer foil obtained by the production method of the transfer foil for in-mold according to claim 1, after performing in-mold injection molding, irradiation with ultraviolet rays on the surface of the molded article A method for producing a molded product comprising the step of completely curing the hard coat layer .

本発明の転写箔を使用すれば、転写時に、凹凸形成層を構成する樹脂の厚みにより、その凹凸パターンに従った凹凸を成形品の表面に形成することができる。また、本発明のインモールド用転写箔は、従来の凹凸模様のない射出成形用金型を使用して、成形品表面に凹凸を形成することができるため、金型の交換にかかるコストを削減できて経済的である。さらに、熱硬化性樹脂を用いて凹凸形成層を設けた基材の反対面に紫外線硬化性樹脂からなるハードコート層を設けることができるので高い表面強度を有する成形品を製造することができる。   If the transfer foil of this invention is used, the unevenness | corrugation according to the uneven | corrugated pattern can be formed in the surface of a molded article by the thickness of resin which comprises an uneven | corrugated formation layer at the time of transcription | transfer. In addition, the in-mold transfer foil of the present invention can form unevenness on the surface of a molded product using a conventional injection mold without an uneven pattern, thus reducing the cost of replacing the mold. It is economical. Furthermore, since a hard coat layer made of an ultraviolet curable resin can be provided on the opposite surface of the substrate on which the unevenness forming layer is provided using a thermosetting resin, a molded product having high surface strength can be produced.

以下、図面を援用して本発明の実施形態の一例を説明する。
インモールド射出成形法とは、（１）インモールド用転写箔を準備する工程、（２）該インモールド用転写箔を射出成形用金型内へ挿入する工程、（３）該射出成形用金型へ樹脂を射出成形し密着させることで、該樹脂の表面にインモールド用転写箔を転写する工程、（４）冷却後、射出成形用金型を開放し、ベースフィルム及び剥離層を剥離して成形品を取り出す工程、の４つの工程からなる射出成形法である。 Hereinafter, an example of an embodiment of the present invention will be described with reference to the drawings.
The in-mold injection molding method includes (1) a step of preparing an in-mold transfer foil, (2) a step of inserting the in-mold transfer foil into an injection mold, and (3) the injection mold. A step of transferring the in-mold transfer foil onto the surface of the resin by injection molding and adhering the resin to the mold, (4) After cooling, the injection mold is opened, and the base film and the release layer are peeled off. This is an injection molding method comprising the four steps of taking out the molded product.

本発明のインモールド用転写箔は、ベースフィルム２と、該ベースフィルム２の一方の面へ剥離層３と、紫外線硬化性樹脂を含むハードコート層４と、印刷層５と、接着層６と、を備え、該ベースフィルム２のもう一方の面に熱硬化性樹脂を含む凹凸形成層１を備える層構成である。   The in-mold transfer foil of the present invention comprises a base film 2, a release layer 3, a hard coat layer 4 containing an ultraviolet curable resin, a printing layer 5, and an adhesive layer 6 on one surface of the base film 2. , And the other surface of the base film 2 has a concavo-convex forming layer 1 containing a thermosetting resin.

ベースフィルム２としては、製造および成形工程で必要な耐熱性、機械的強度、耐溶剤性などがあれば、用途に応じて種々の材料が適用できる。例えば、ポリエステル系樹脂、ポリアミド系樹脂、ポリオレフィン系樹脂、ビニル系樹脂、アクリル系樹脂、セルロース系樹脂、などがある。好ましくは、耐熱性、機械的強度の点で、ポリエチレンテレフタレ
ート、ポリエチレンナフタレートなどのポリエステル系樹脂のフィルムが挙げられ、なかでもポリエチレンテレフタレート樹脂のフィルムが最適である。 As the base film 2, various materials can be applied depending on the use as long as the base film 2 has heat resistance, mechanical strength, solvent resistance and the like necessary in the production and molding processes. For example, there are polyester resins, polyamide resins, polyolefin resins, vinyl resins, acrylic resins, cellulose resins, and the like. Preferred are films of polyester resins such as polyethylene terephthalate and polyethylene naphthalate in terms of heat resistance and mechanical strength. Among these, films of polyethylene terephthalate resin are most suitable.

剥離層３の材質としては、必要な剥離性を備えた樹脂であれば特に限定されないが、本発明のインモールド用転写箔ではメラミン系樹脂を用いることが好ましい。該メラミン系樹脂を用いることで、ハードコート層４との組み合わせで安定した剥離性を発揮する。剥離層３の形成方法としては、周知の印刷法や塗工法を用いることが出来る。   The material of the release layer 3 is not particularly limited as long as it is a resin having a required release property, but it is preferable to use a melamine resin in the in-mold transfer foil of the present invention. By using the melamine resin, stable releasability is exhibited in combination with the hard coat layer 4. As a method for forming the release layer 3, a known printing method or coating method can be used.

ハードコート層４は、転写後にベースフィルム２を剥離した際に、成形品の最表面層となる層である。ハードコート層４の材料としては、紫外線で硬化する紫外線硬化性樹脂を用いる。紫外線硬化性のハードコート層であれば、紫外線照射によって直ちに成形品表面を硬化させることができるため、成形品の生産効率が向上することになる。また、未硬化の状態で成形し、成形後に硬化させることで、成形性向上と物性向上の両立が可能である。ハードコート層４の形成方法としては、周知の印刷法や塗工法を用いることが出来る。   The hard coat layer 4 is a layer that becomes the outermost surface layer of the molded product when the base film 2 is peeled off after transfer. As a material for the hard coat layer 4, an ultraviolet curable resin that is cured by ultraviolet rays is used. In the case of an ultraviolet curable hard coat layer, the surface of the molded product can be immediately cured by irradiation with ultraviolet rays, so that the production efficiency of the molded product is improved. Further, by molding in an uncured state and curing after molding, it is possible to improve both moldability and physical properties. As a method for forming the hard coat layer 4, a known printing method or coating method can be used.

印刷層５の材料としては、適切な色の顔料または染料を着色剤として含有する着色インキを用いる。印刷層の形成方法としては、オフセット印刷法、グラビア印刷法、スクリーン印刷法などの通常の印刷法を用いることが出来る。好ましくは、多色刷りや階調表現が可能で、且つ、大量生産に適しているグラビア印刷法で印刷するのが良い。また、ハードコート層４との密着性を向上させるために、印刷層５とハードコート層４との間にアンカー層（図示せず）を設けても良い。アンカー層の形成方法としては、グラビア印刷法、スクリーン印刷法などの印刷法を用いることが出来る。特に、膜厚・生産性の点からグラビア印刷法で印刷するのが望ましい。   As the material of the printing layer 5, a colored ink containing a pigment or dye of an appropriate color as a colorant is used. As a method for forming the printing layer, a normal printing method such as an offset printing method, a gravure printing method, or a screen printing method can be used. It is preferable to print by a gravure printing method that can perform multicolor printing and gradation expression and is suitable for mass production. An anchor layer (not shown) may be provided between the printing layer 5 and the hard coat layer 4 in order to improve the adhesion with the hard coat layer 4. As a method for forming the anchor layer, a printing method such as a gravure printing method or a screen printing method can be used. In particular, it is desirable to print by a gravure printing method from the viewpoint of film thickness and productivity.

接着層６は、成形品の表面に上記の各層を接着するものである。接着層６としては、成形樹脂７に適した感熱性あるいは感圧性の樹脂を適宜使用する。接着層の形成方法としては、グラビア印刷法、スクリーン印刷法などの印刷法を用いることが出来る。特に、膜厚・生産性の点からグラビア印刷法で印刷するのが望ましい。なお、印刷層５が成形品に対して充分接着性を有しており、接着層としての効果も備えている場合には、接着層６を別に設けなくても良い。   The adhesive layer 6 adheres each of the above layers to the surface of the molded product. As the adhesive layer 6, a heat-sensitive or pressure-sensitive resin suitable for the molding resin 7 is appropriately used. As a method for forming the adhesive layer, a printing method such as a gravure printing method or a screen printing method can be used. In particular, it is desirable to print by a gravure printing method from the viewpoint of film thickness and productivity. In addition, when the printing layer 5 has sufficient adhesiveness with respect to a molded article and also has the effect as an adhesive layer, it is not necessary to provide the adhesive layer 6 separately.

ベースフィルム２の反剥離層側に設けられる凹凸形成層１は、グラビア印刷法やスクリーン印刷法によって印刷することで形成できる。凹凸形成層１の材料としては転写時に受ける熱や圧力に耐えることのできる熱硬化性樹脂や紫外線硬化性樹脂を用いることができる。しかし、紫外線硬化性樹脂を用いると、成形前にハードコート層も硬化して、成形性が損なわれる。そこで、熱硬化性樹脂を用いて凹凸形成層１を形成するのが良い。   The unevenness forming layer 1 provided on the side of the base film 2 opposite to the peeling layer can be formed by printing by a gravure printing method or a screen printing method. As the material of the unevenness forming layer 1, a thermosetting resin or an ultraviolet curable resin that can withstand the heat and pressure received during transfer can be used. However, when an ultraviolet curable resin is used, the hard coat layer is also cured before molding, and moldability is impaired. Therefore, it is preferable to form the unevenness forming layer 1 using a thermosetting resin.

また、凹凸形成層１は、熱硬化性樹脂をグラビア印刷法、グラビアコート法、ロールコート法、ナイフコート法、シルクスクリーン印刷法、その他通常のコート法ないし印刷法で塗工後、該熱硬化性樹脂をエンボス加工することによって形成しても良い。   The unevenness forming layer 1 is formed by applying a thermosetting resin by a gravure printing method, a gravure coating method, a roll coating method, a knife coating method, a silk screen printing method, or other ordinary coating methods or printing methods, and then the thermosetting resin. It may be formed by embossing a functional resin.

各層を上記のように積層して、図１に示すような、本発明のインモールド用転写箔が準備できる。該インモールド用転写箔を用いて、インモールド射出成形することにより、表面に凹凸を有する成形品を製造することができる。
インモールド射出成形は、該インモールド用転写箔を射出成形用金型８内へ挿入し、該インモールド転写箔の印刷層５側から該射出成形用金型８のキャビティ内へ成形樹脂７を射出成形することで、該成形樹脂７の表面にインモールド用転写箔を転写し、冷却後、射出成形用金型８を解放し、インモールド用転写箔のベースフィルム２及び剥離層３を剥離して成形品を取り出すという公知の順序で行うことが出来る。
この方法で射出成形用金型８のキャビティ内へ成形樹脂７を射出成形し、インモールド
用転写箔に圧力をかけることで、該インモールド用転写箔における凹凸形成層１を構成する樹脂の厚みにより、図２に示すように、そのパターンに従って成形品のインモールド用転写箔側の面に凹凸が形成される（図３参照）ことになる。 By laminating each layer as described above, an in-mold transfer foil of the present invention as shown in FIG. 1 can be prepared. By using in-mold injection molding using the in-mold transfer foil, a molded product having irregularities on the surface can be produced.
In in-mold injection molding, the in-mold transfer foil is inserted into the injection mold 8 and the molding resin 7 is injected into the cavity of the injection mold 8 from the printed layer 5 side of the in-mold transfer foil. By injection molding, the in-mold transfer foil is transferred to the surface of the molding resin 7, and after cooling, the injection mold 8 is released, and the base film 2 and the release layer 3 of the in-mold transfer foil are peeled off. Then, it can be performed in a known order of taking out the molded product.
By this method, the molding resin 7 is injection-molded into the cavity of the injection mold 8 and pressure is applied to the in-mold transfer foil, whereby the thickness of the resin constituting the unevenness forming layer 1 in the in-mold transfer foil. Accordingly, as shown in FIG. 2, irregularities are formed on the surface of the molded product on the side of the in-mold transfer foil according to the pattern (see FIG. 3).
