Description
本発明は、トナー画像を転写するための転写紙を作る方法に係わるもので、転写紙上に複写形成されたトナー画像における、トナー画像部分のみに転写用の接着剤を選択的に塗布する方法に関するものである。 The present invention relates to a method of making a transfer paper for transferring a toner image, and relates to a method of selectively applying a transfer adhesive only to a toner image portion in a toner image copied and formed on the transfer paper. Is.
従来この種のトナー画像を接着剤によって転写する方法は、各種さまざまな方法で行われている現状であるが、その最大の課題とする所は、いかにしてトナー画像の部分のみに転写用の接着剤を積層させるかと云う点にある。 Conventionally, this type of toner image transfer method using an adhesive is currently carried out in various ways, but the biggest problem is how to transfer only the toner image portion. It is in the point of laminating an adhesive.
次に、従来の方法としては、次のようなものが実用化されている。
１ 転写紙に形成されたトナー画像と同一パターンの版を作り、スクリーン印刷により、接着剤を印刷して積層する方法。
２ 接着剤を全面塗布した転写紙上にトナー画像を形成し、カッティングナイフを用いて画像の輪郭を切り抜き、余分な接着剤を切除する方法。
３ 接着剤を全面塗布した転写紙上にトナー画像を形成し、接着剤のみを溶融除去する方法。
４ トナー画像の上面全体に接着剤を塗布し、その上に感光性樹脂を塗布積層した後、ネガフィルムを重ねて露光をし、水洗によって不用部分の感光性樹脂を除去してマスキングを施し、接着剤のみを溶融する有機溶剤で画像面を払拭し、しかる後現像剤によって感光性樹脂のマスキングを払拭除去する方法。
などがある。Next, the following methods have been put into practical use as conventional methods.
1 A method in which a plate having the same pattern as a toner image formed on a transfer paper is made, and an adhesive is printed and laminated by screen printing.
2 A method in which a toner image is formed on a transfer paper on which the entire surface of an adhesive has been applied, the outline of the image is cut out using a cutting knife, and excess adhesive is removed.
3 A method in which a toner image is formed on a transfer paper on which an adhesive has been entirely applied, and only the adhesive is melted and removed.
4 Apply the adhesive on the entire upper surface of the toner image, apply and laminate the photosensitive resin on top of it, expose the negative film, and remove the unnecessary photosensitive resin by washing with water to mask it. A method in which the image surface is wiped with an organic solvent that melts only the adhesive, and then the photosensitive resin masking is wiped away with a developer.
and so on.
上記いずれの方法においても、工程が非常に複雑であり、手間と時間を要する上、有機溶剤等の有害な材料や、スクリーン印刷、コンピュータカッティング等の各種高額な設備も必要としていたため、安全且つ簡便、安価に画像部分のみに接着剤が塗布できる方法が要望されているものである。 In any of the above methods, the process is very complicated, requires labor and time, and also requires harmful materials such as organic solvents and various expensive equipment such as screen printing and computer cutting. There is a demand for a simple and inexpensive method for applying an adhesive only to an image portion.
陶磁器デザインの業界では、白地の陶磁器に任意のカラー図案を施して焼成量産する前の段階で、カラーコピーを陶磁器に転写してデザインの検討をすることが行われている。そして、現在使われている水転写紙は、全面に透明な膜を張った転写紙であり、画像が膜ごと転写されるため、転写されたカラーコピーのトナー画像の周りに透明な膜が付随して仕上がり、画像だけが転写される量産の製品とは、趣の異なった風体になってしまうという不具合があった。
しかしながら、トナー画像のみを転写しようとすると、前述の如く、非常に面倒な手間や高額の機械設備を必要とする問題があった。
本発明は上記の問題点に鑑みて考案されたものであり、危険な薬品や高額な機械設備を用いることなく、誰でも簡単にトナー画像のみが転写できる転写紙を作るための、接着剤の塗布方法を提供するものである。In the ceramic design industry, a design is examined by transferring a color copy to ceramics before applying any color designs to white ceramics and firing them in mass production. The water transfer paper currently used is a transfer paper with a transparent film on the entire surface. Since the image is transferred with the film, a transparent film is attached around the transferred color copy toner image. As a result, there is a problem that the finished product is different from a mass-produced product in which only an image is transferred.
However, when only the toner image is transferred, there is a problem that, as described above, very troublesome labor and expensive mechanical equipment are required.
The present invention has been devised in view of the above-described problems, and is an adhesive for making a transfer paper on which anyone can easily transfer only a toner image without using dangerous chemicals or expensive mechanical equipment. An application method is provided.
本発明は、上記目的を達成するために、本発明のトナー画像への接着剤塗布方法においては、画像転写用の接着剤として、ホットメルト接着性を有する熱可塑性樹脂の水性エマルジョンタイプのヒドロゾルを使用する。また、樹脂としては、アクリル樹脂、ポリウレタン樹脂、塩化ビニル樹脂、酢酸ビニル樹脂、スチレン樹脂、ポリエステル樹脂等が適している。用途に応じてこれらの共重合物や混合物を用いるものも良い。エマルジョンの粘度はゲル状態ではなく、流動性のよいゾル状態で使用する。
更に、トナー画像を形成する転写紙は、水転写紙に使われているデキストリン表面のものではなく、紙等のシート状基材の上に、シリコン又はアルキッド系の油性タイプの離型剤を塗布した撥水性のある表面を持つものを使用する。In order to achieve the above object, according to the present invention, in the method of applying an adhesive to a toner image of the present invention, an aqueous emulsion type hydrosol of a thermoplastic resin having hot melt adhesive property is used as an adhesive for image transfer. use. As the resin, acrylic resin, polyurethane resin, vinyl chloride resin, vinyl acetate resin, styrene resin, polyester resin and the like are suitable. Depending on the application, those using these copolymers or mixtures may be used. The viscosity of the emulsion is not in a gel state but in a sol state with good fluidity.
Furthermore, the transfer paper that forms the toner image is not the dextrin surface used for water transfer paper, but a silicone or alkyd oil-based release agent is applied on a sheet-like substrate such as paper. Use one with a water-repellent surface.
以上説明したように、本発明のトナー画像への接着剤塗布方法によれば、従来のものと異なり、トナー画像部分のみが容易に転写される転写紙を容易に作ることができ、風合いの良い転写製品を製作することが可能となる効果がある。
そして、離型シートにトナー画像を形成した後、トナー画像の上面にホットメルト接着を有する熱可塑性樹脂のエマルジョンのヒドロゾルを刷毛等で塗布することによって、トナー画像より外周にはみ出して塗られたヒドロゾルが、油性の離型剤との反発と、自体の表面張力によって容易にトナー画像部分の表に確実に収斂できると云う効果を有する。また、本発明によれば、高額な機械設備や専門の知識を必要とせず、事務所やコンビニに普及しているカラーコピー機やレーザープリンタを使用して手軽で簡単に製作できると云う効果がある。更に、本発明は、１００℃以下の温度と水性接着剤という安全な条件で転写が可能となり、従って家庭や学校で誰でも簡単に作業を実施できる効果と、使用する材料が低廉であり、従来のものより大幅なコストダウンが達成できる実利的な効果がある。As described above, according to the method for applying an adhesive to a toner image of the present invention, unlike the conventional method, a transfer paper on which only a toner image portion is easily transferred can be easily produced, and the texture is good. There is an effect that a transfer product can be manufactured.
Then, after forming a toner image on the release sheet, a hydrosol of a thermoplastic resin emulsion having hot melt adhesion is applied to the upper surface of the toner image with a brush or the like, so that the hydrosol is applied to the outer periphery of the toner image. However, it has an effect that it can be easily converged on the surface of the toner image portion easily by repulsion with the oil-based release agent and its own surface tension. Further, according to the present invention, there is an effect that it can be easily and easily manufactured using a color copier or a laser printer which is widely used in offices and convenience stores without requiring expensive mechanical equipment and specialized knowledge. is there. Furthermore, the present invention enables transfer at a temperature of 100 ° C. or less and a safe condition of a water-based adhesive, so that anyone can easily work at home or school, and the material used is inexpensive, There is a practical effect that can achieve a significant cost reduction.
この転写紙の離型面にカラーコピーやレーザープリンタ等を用いて、トナー画像を複写形成し、画像上面に上記のヒドロゾル状の接着剤を筆で塗布すると、画像部分からはみ出して塗布された接着剤の水成分と、油性の離型剤とが反発し、且つ接着剤を構成する熱可塑性樹脂成分とトナーを構成する熱可塑性樹脂との親和性により、トナー画像上では接着剤が反発することなく、ヒドロゾルの接着剤の水成分による表面張力によりトナー上に収斂し、トナー画像部分のみに接着剤の乾燥被膜が形成されるものである。 When a toner image is copied and formed on the release surface of the transfer paper using a color copy or a laser printer, and the above-mentioned hydrosol-like adhesive is applied to the upper surface of the image with a brush, the adhesive is applied to protrude from the image portion. The water component of the agent and the oil-based release agent repel each other, and due to the affinity between the thermoplastic resin component constituting the adhesive and the thermoplastic resin constituting the toner, the adhesive repels on the toner image. Rather, it converges on the toner due to the surface tension of the water component of the hydrosol adhesive, and a dry film of the adhesive is formed only on the toner image portion.
本発明の実施例を図面について説明すると、図１の（イ）図の如く、離型シート（Ａ）は、シート状基材（１）と、そのシート状基材（１）の表面にシリコン等の油性離型剤（２）を塗布して形成されている。
該離型シート（Ａ）には、静電式複写機またはレーザープリンタによるトナー画像（３）を形成する。その後にトナー画像（３）には、図１の（ロ）図の如く上部表面にホットメルト接着性を有する熱可塑性樹脂のエマルジョンの接着剤ヒドロゾル（５）を刷毛等で塗布する。その後、トナー画像（３）より外周にはみ出した該接着剤ヒドロゾル（５）が、（ハ）図の如く油性離型剤（２）との反発と、自体の表面張力によって、トナー画像（３）（３）のみの表面に収斂させるものである。（ニ）図に示す符号（６）は、その後、該接着剤ヒドロゾル（５）が、トナー画像（３）の表面で乾燥した乾燥接着剤を示したものである。The embodiment of the present invention will be described with reference to the drawings. As shown in FIG. 1 (a), the release sheet (A) comprises a sheet-like substrate (1) and silicon on the surface of the sheet-like substrate (1). It is formed by applying an oil-based mold release agent (2).
A toner image (3) is formed on the release sheet (A) by an electrostatic copying machine or a laser printer. Thereafter, an adhesive hydrosol (5) of a thermoplastic resin emulsion having hot-melt adhesiveness is applied to the upper surface of the toner image (3) with a brush or the like as shown in FIG. Thereafter, the adhesive hydrosol (5) protruding from the outer periphery of the toner image (3) is repelled from the oil-based release agent (2) as shown in FIG. (3) Converge only on the surface. (D) The reference numeral (6) shown in the figure indicates a dry adhesive obtained by drying the adhesive hydrosol (5) on the surface of the toner image (3).
離型シート（Ａ）はシート状基材（１）にキャスティングコート紙８５ｇ／ｍ２厚にシリコン系離型剤（２）を塗布したものを用い、リコー製レーザープリンタ・イプシオＣＸ７２００で離型面にカラーイラストをプリントした。接着剤は、アクリル・ウレタン混合物のエマルジョンのヒドロゾルを用い、筆により画像上に塗布した。画像からはみ出した部分の接着剤は、約３０秒後には完全にトナー部分に収斂し、非画像部分には接着剤が残らない状態が出来上がった。
また、出来上がった転写紙を用いて、市販のマグカップに転写を行った。マグカップに９５℃の熱湯をポットより注いでカップ全体を温め、転写紙の接着面をカップの側面に押し付けて、転写紙の上から布で擦り、カップが冷めてから転写紙を剥がしたところ、画像はカップに完全に転写した。アクリル・ウレタン系の水性エマルジョン接着剤を用いることにより、１００℃以下の安全な温度で転写が可能であった。この他マグカップを電気オーブンで１００℃で５分間温めた状態のものに、上記と同様の方法で転写をしたところ、この場合も完全に転写をすることができた。
前記の如く、出来上がったマグカップは、トナー画像部分のみが転写されており、焼成量産される本製品のマグカップと非常に似た仕上がりを得ることができた。The release sheet (A) was obtained by applying a silicon-based release agent (2) to a sheet-like base material (1) with a cast-coated paper of 85 g / m 2 thickness, and using a Ricoh laser printer Ipcio CX7200 to release the release surface. A color illustration was printed on As the adhesive, an acrylic hydrosol emulsion hydrosol was used and applied onto the image with a brush. The adhesive at the portion protruding from the image was completely converged on the toner portion after about 30 seconds, and the adhesive was not left in the non-image portion.
Moreover, it transferred to a commercially available mug using the completed transfer paper. Pour hot water of 95 ° C into the mug from the pot to warm the whole cup, press the adhesive surface of the transfer paper against the side of the cup, rub it with a cloth from the top of the transfer paper, and after the cup cools, peel off the transfer paper, The image was completely transferred to the cup. By using an acrylic / urethane aqueous emulsion adhesive, transfer was possible at a safe temperature of 100 ° C. or lower. In addition, when a mug was heated in an electric oven at 100 ° C. for 5 minutes and transferred in the same manner as described above, the transfer could be completed in this case as well.
As described above, in the completed mug, only the toner image portion was transferred, and a finish very similar to the mug of the product to be mass-produced can be obtained.
