Description

本考案は水変色性教習具及びそれを用いた水変色性教習具セットに関する。更に詳細には、文字の書き順を習得するための水変色性教習具及びそれを用いた水変色性教習具セットに関する。   The present invention relates to a water discoloration learning tool and a water discoloration learning tool set using the same. More specifically, the present invention relates to a water discoloration learning tool for learning the writing order of characters and a water discoloration learning tool set using the same.

従来、支持体上に低屈折率顔料をバインダー樹脂と共に分散状態に固着させた多孔質層を設けた水筆紙が開示されており、水を含ませた筆等を用いて筆記すると所望の文字を描くことができる(例えば、特許文献1参照)。
また、支持体上に非変色性像(文字)と多孔質層を形成した筆記シートが開示されており、水を含ませた筆等を用いて多孔質層上をなぞり書きすることにより変色させ、きれいな文字を書く練習を行うことができる(例えば、特許文献2参照)。
前記水筆紙や筆記シートはいずれも水の適用によって繰り返し文字を描く教習具として用いることができ、文字の形を覚えたり、きれいな形の文字を書く練習を行うのに適したものである。しかしながら、文字の書き順を習得する用途に関して、従来の水筆発色紙や筆記シートは十分な機能を有していない。一般的に文字の書き順の習得は文字の近傍に書き順を表す数字が印刷されており、該数字を見ながら、筆記具を用いて文字上をなぞり書きすることにより行われるものの、予め書き順が視認されている状態では教習具としての効果に乏しく、興味も半減するものであり、しかも、学習効果を確認する用途に使用することはできなかった。

Conventionally, a water pen paper provided with a porous layer in which a low refractive index pigment is fixed in a dispersed state together with a binder resin on a support has been disclosed, and when writing with a brush containing water, etc., desired characters are disclosed. It can be drawn (see, for example, Patent Document 1).
In addition, a writing sheet in which a non-color-changing image (characters) and a porous layer are formed on a support is disclosed, and the color is changed by tracing the surface of the porous layer using a brush containing water. It is possible to practice writing beautiful characters (for example, see Patent Document 2).
Both the water brush paper and the writing sheet can be used as a teaching tool for drawing characters repeatedly by applying water, and are suitable for practicing to write letters with beautiful shapes. However, with respect to the use of learning the writing order of characters, the conventional water brush coloring paper and writing sheet do not have sufficient functions. In general, learning of the writing order of characters is performed by printing a number indicating the writing order in the vicinity of the character and tracing the character using a writing instrument while looking at the number. In the state where is visually recognized, the effect as a learning tool is poor, the interest is halved, and it cannot be used for the purpose of confirming the learning effect.

本考案は、文字の書き順を習得する教習具としての実用性に優れ、しかも、学習の成果を確認することもできる利便性に富む水変色性教習具及びそれを用いた水変色性教習具セットを提供できる。   The present invention is highly practical as a learning tool for learning the writing order of characters, and also has a highly convenient water discoloration learning tool that can confirm the results of learning, and a water discoloration learning tool using the same. Can provide set.

前記教習具は、支持体上に平仮名、片仮名、漢字から選ばれる非変色性像を設け、前記非変色性像上に低屈折率顔料をバインダー樹脂と共に分散状態に固着させた非吸水状態で不透明であり、吸水状態で透明化する多孔質層を設け、前記多孔質層には多孔質層の一部に内在し、共存状態の撥水性樹脂像を設けてなる。
前記支持体としては、紙、合成紙、ゴム、プラスチック、金属、石材、ガラス、布帛、木材等の各種材料が用いられる。
前記支持体の形状は立体形状であってもよいが、シート状(平面形状)であることが好ましい。
The learning tool is provided with a non-color-changing image selected from Hiragana, Katakana, and Kanji on a support, and is opaque in a non-water-absorbing state in which a low refractive index pigment is fixed in a dispersed state together with a binder resin on the non-color-changing image. A porous layer that is transparent in a water-absorbing state is provided, and the porous layer is provided in a part of the porous layer and provided with a coexisting water-repellent resin image.
As the support, various materials such as paper, synthetic paper, rubber, plastic, metal, stone, glass, fabric, and wood are used.
The shape of the support may be a three-dimensional shape, but is preferably a sheet shape (planar shape).

前記平仮名、片仮名、漢字から選ばれる非変色性像は、印刷インキにより支持体上にスクリーン印刷、オフセット印刷、グラビヤ印刷、コーター、タンポ印刷、転写等の印刷手段により形成する他、非変色性像を形成したラベルを支持体に貼着することもできる。   The non-color-changing image selected from the hiragana, katakana, and kanji characters is formed on the support with printing ink by a printing means such as screen printing, offset printing, gravure printing, coater, tampo printing, transfer, and the like. The label formed with can also be attached to a support.

前記非変色性像上に形成される多孔質層は、常態、即ち、乾燥状態では下層を隠蔽し、水等の液体を吸液した状態では透明又は半透明化して下層の色調を顕出させる。
よって、前記多孔質層に水を付着させて非変色性像を現出させることができる。
前記低屈折率顔料としては、珪酸及びその塩、バライト粉、硫酸バリウム、炭酸バリウム、炭酸カルシウム、石膏、クレー、タルク、アルミナホワイト、炭酸マグネシウム等が挙げられ、これらは屈折率が1.4〜1.8の範囲にあり、液体を吸液すると良好な透明性を示すものである。
なお、前記珪酸の塩としては、珪酸アルミニウム、珪酸アルミニウムカリウム、珪酸アルミニウムナトリウム、珪酸アルミニウムカルシウム、珪酸カリウム、珪酸カルシウム、珪酸カルシウムナトリウム、珪酸ナトリウム、珪酸マグネシウム、珪酸マグネシウムカリウム等が挙げられる。
前記低屈折率顔料の粒径は特に限定されるものではないが、0.03〜10.0μmのものが好適に用いられる。
又、前記低屈折率顔料は2種以上を併用することもできる。
尚、好適に用いられる低屈折率顔料としては珪酸が挙げられる。
前記珪酸は、乾式法により製造させる珪酸(以下、乾式法珪酸と称する)であってもよいが、湿式法により製造される珪酸(以下、湿式法珪酸と称する)が好適である。
この点を以下に説明すると、珪酸は非晶質の無定形珪酸として製造され、その製造方法により、四塩化ケイ素等のハロゲン化ケイ素の熱分解等の気相反応を用いる乾式法によるものと、ケイ酸ナトリウム等の酸による分解等の液相反応を用いる湿式法によるものとに大別される。乾式法珪酸と湿式法珪酸とでは構造が異なり、前記乾式法珪酸は珪酸が密に結合した構造であるのに対して、湿式法珪酸は、珪酸が縮合して長い分子配列を形成した構造部分を有している。従って、湿式法珪酸は乾式法珪酸と比較して分子構造が粗になるため、湿式法珪酸を多孔質層に適用した場合、乾式法珪酸を用いた系と比較して乾燥状態における光の乱反射性に優れ、常態での隠蔽性が大きくなるものと推察される。又、多孔質層は水を吸液させるものであるから、湿式法珪酸は乾式法珪酸に比べて粒子表面にシラノール基として存在する水酸基が多く、親水性の度合いが大であり、好適に用いられる。
尚、前記多孔質層の常態での隠蔽性と吸液状態での透明性を調整するために、湿式法珪酸と共に、他の汎用の低屈折率顔料を併用することもできる。
The porous layer formed on the non-color-changing image conceals the lower layer in a normal state, that is, in a dry state, and becomes transparent or translucent in a state in which a liquid such as water is absorbed to reveal the color tone of the lower layer. .
Therefore, it is possible to make the non-color-changing image appear by attaching water to the porous layer.
Examples of the low refractive index pigment include silicic acid and salts thereof, barite powder, barium sulfate, barium carbonate, calcium carbonate, gypsum, clay, talc, alumina white, magnesium carbonate, and the like. It is in the range of 1.8 and exhibits good transparency when liquid is absorbed.
Examples of the silicic acid salts include aluminum silicate, aluminum potassium silicate, sodium aluminum silicate, aluminum calcium silicate, potassium silicate, calcium silicate, calcium sodium silicate, sodium silicate, magnesium silicate, and magnesium potassium silicate.
The particle size of the low refractive index pigment is not particularly limited, but 0.03 to 10.0 μm is preferably used.
Two or more of the low refractive index pigments can be used in combination.
In addition, silicic acid is mentioned as a low refractive index pigment used suitably.
The silicic acid may be silicic acid produced by a dry process (hereinafter referred to as dry process silicic acid), but is preferably silicic acid produced by a wet process (hereinafter referred to as wet process silicic acid).
To explain this point below, silicic acid is produced as amorphous amorphous silicic acid, and according to its production method, a dry method using a gas phase reaction such as thermal decomposition of silicon halide such as silicon tetrachloride, It is roughly classified into a wet process using a liquid phase reaction such as decomposition with an acid such as sodium silicate. The dry process silicic acid and the wet process silicic acid have different structures, and the dry process silicic acid has a structure in which silicic acid is closely bound, whereas the wet process silicic acid has a structure part in which a long molecular arrangement is formed by condensation of silicic acid. have. Therefore, since wet-process silicic acid has a coarser molecular structure than dry-process silicic acid, when wet-process silicic acid is applied to the porous layer, the diffused reflection of light in the dry state compared to systems using dry-process silicic acid It is presumed that the concealability in the normal state is increased. In addition, since the porous layer absorbs water, the wet process silicic acid has more hydroxyl groups present as silanol groups on the particle surface than the dry process silicic acid, and has a high degree of hydrophilicity. It is done.
In addition, in order to adjust the concealability in the normal state of the porous layer and the transparency in the liquid absorption state, other general-purpose low-refractive-index pigments can be used in combination with the wet method silicic acid.

前記バインダー樹脂としては、ウレタン系樹脂、ナイロン樹脂、酢酸ビニル樹脂、アクリル酸エステル樹脂、アクリル酸エステル共重合樹脂、アクリルポリオール樹脂、塩化ビニル−酢酸ビニル共重合樹脂、マレイン酸樹脂、ポリエステル樹脂、スチレン樹脂、スチレン共重合樹脂、ポリエチレン樹脂、ポリカーボネート樹脂、エポキシ樹脂、スチレン−ブタジエン共重合樹脂、アクリロニトリル−ブタジエン共重合樹脂、メタクリル酸メチル−ブタジエン共重合樹脂、ブタジエン樹脂、クロロプレン樹脂、メラミン樹脂、及び前記各樹脂エマルジョン、カゼイン、澱粉、セルロース誘導体、ポリビニルアルコール、尿素樹脂、フェノール樹脂等が挙げられる。
前記低屈折率顔料とバインダー樹脂の混合比率は、低屈折率顔料の種類及び性状に左右されるが、好ましくは、低屈折率顔料1重量部に対してバインダー樹脂固形分0.5〜2重量部であり、より好ましくは、0.8〜1.5重量部である。低屈折率顔料1重量部に対してバインダー樹脂固形分が0.5重量部未満の場合には、前記多孔質層の実用的な皮膜強度を得ることが困難であり、2重量部を越える場合には、前記多孔質層内部への水の浸透性が悪くなる。
前記多孔質層は、一般的な塗膜と比較して着色剤に対するバインダー樹脂の混合比率が小さいため、十分な皮膜強度が得られ難い。そこで、前記のバインダー樹脂のうち、ナイロン樹脂又はウレタン系樹脂を用いて耐擦過強度を高めることが好ましい。
前記ウレタン系樹脂としては、ポリエステル系ウレタン樹脂、ポリカーボネート系ウレタン樹脂、ポリエーテル系ウレタン樹脂等があり、2種以上を併用することもできる。又、前記樹脂として水に乳化分散したウレタン系エマルジョン樹脂や、イオン性を有するウレタン樹脂(ウレタンアイオノマー)自体のイオン基により乳化剤を必要とすることなく自己乳化して、水中に溶解乃至分散したコロイド分散型(アイオノマー型)ウレタン樹脂を用いることもできる。
前記ウレタン系樹脂は水性ウレタン系樹脂又は油性ウレタン系樹脂のいずれを用いることもできるが、本考案においては水性ウレタン系樹脂、殊に、ウレタン系エマルジョン樹脂やコロイド分散型ウレタン系樹脂が好適に用いられる。
前記ウレタン系樹脂は単独で用いることもできるが、支持体の種類や皮膜に必要とされる性能に応じて、他のバインダー樹脂を併用することもできる。ウレタン系樹脂以外のバインダー樹脂を併用する場合、実用的な皮膜強度を得るためには、前記多孔質層のバインダー樹脂中にウレタン系樹脂を固形分比率で30質量%以上含有させることが好ましい。
前記バインダー樹脂において、架橋性のものは任意の架橋剤を添加して架橋させることにより、さらに皮膜強度を向上させることができる。
前記バインダー樹脂には、水との親和性に大小が存在するが、これらを組み合わせることによって多孔質層中への浸透時間、浸透度合い、浸透後の乾燥の遅速を調整することができる。更に、適宜分散剤を添加して前記調整をコントロールすることができる。
前記多孔質層の塗布量は5〜50g/m、好ましくは、10〜30g/mである。
5g/m未満では、常態で十分な隠蔽性を得ることが困難であり、又、50g/mを越えると吸液時に十分な透明性を得ることが困難である。
Examples of the binder resin include urethane resin, nylon resin, vinyl acetate resin, acrylic ester resin, acrylic ester copolymer resin, acrylic polyol resin, vinyl chloride-vinyl acetate copolymer resin, maleic resin, polyester resin, styrene. Resin, styrene copolymer resin, polyethylene resin, polycarbonate resin, epoxy resin, styrene-butadiene copolymer resin, acrylonitrile-butadiene copolymer resin, methyl methacrylate-butadiene copolymer resin, butadiene resin, chloroprene resin, melamine resin, and the above Each resin emulsion, casein, starch, cellulose derivative, polyvinyl alcohol, urea resin, phenol resin and the like can be mentioned.
The mixing ratio of the low refractive index pigment and the binder resin depends on the kind and properties of the low refractive index pigment, but preferably the binder resin solid content is 0.5 to 2 weights with respect to 1 part by weight of the low refractive index pigment. Part, more preferably 0.8 to 1.5 parts by weight. When the binder resin solid content is less than 0.5 parts by weight with respect to 1 part by weight of the low refractive index pigment, it is difficult to obtain a practical film strength of the porous layer, and the content exceeds 2 parts by weight. In this case, the water permeability into the porous layer is deteriorated.
Since the porous layer has a smaller mixing ratio of the binder resin to the colorant than a general coating film, it is difficult to obtain sufficient film strength. Therefore, among the binder resins, it is preferable to increase the scratch resistance using a nylon resin or a urethane resin.
Examples of the urethane resin include a polyester urethane resin, a polycarbonate urethane resin, and a polyether urethane resin, and two or more of them can be used in combination. In addition, a urethane emulsion resin emulsified and dispersed in water as the resin, or a colloid dissolved or dispersed in water by self-emulsifying without the need for an emulsifier due to the ionic group of the ionic urethane resin (urethane ionomer) itself. A dispersion type (ionomer type) urethane resin can also be used.
As the urethane resin, either a water-based urethane resin or an oil-based urethane resin can be used. In the present invention, a water-based urethane resin, particularly a urethane emulsion resin or a colloidally dispersed urethane resin is preferably used. It is done.
The urethane resin can be used alone, but other binder resins can be used in combination depending on the type of support and the performance required for the coating. When a binder resin other than a urethane resin is used in combination, in order to obtain a practical film strength, it is preferable to contain a urethane resin in a solid content ratio of 30% by mass or more in the binder resin of the porous layer.
In the binder resin, the crosslinkable resin can be further improved in film strength by adding an arbitrary crosslinking agent and crosslinking.
The binder resin has a large or small affinity with water. By combining these, the penetration time into the porous layer, the degree of penetration, and the slow speed of drying after the penetration can be adjusted. Furthermore, the said adjustment can be controlled by adding a dispersing agent suitably.
The coating amount of the porous layer is 5 to 50 g / m 2 , preferably 10 to 30 g / m 2 .
If it is less than 5 g / m 2 , it is difficult to obtain sufficient concealability in a normal state, and if it exceeds 50 g / m 2 , it is difficult to obtain sufficient transparency upon liquid absorption.

なお、前記多孔質層中には、二酸化チタン被覆雲母、酸化鉄−二酸化チタン被覆雲母、酸化鉄被覆雲母、グアニン、絹雲母、塩基性炭酸鉛、酸性砒酸鉛、オキシ塩化ビスマス等の金属光沢顔料を添加したり、一般染料や顔料、蛍光染料や蛍光顔料を添加して色変化を多様化することができる。   In the porous layer, metallic gloss pigments such as titanium dioxide coated mica, iron oxide-titanium dioxide coated mica, iron oxide coated mica, guanine, sericite, basic lead carbonate, acidic lead arsenate, bismuth oxychloride, etc. The color change can be diversified by adding general dyes and pigments, fluorescent dyes and fluorescent pigments.

前記多孔質層には、多孔質層の一部に内在し、共存状態に撥水性樹脂像が配設され、前記像は平仮名、片仮名、漢字から選ばれる非変色性像の書き順を現出させて視認する部分として機能する。
撥水性樹脂像は、多孔質層のみ形成した部分は水等の液体を吸液した状態で透明又は半透明化して下層の色調が現出するものの、多孔質層の撥水性樹脂像を形成した部分は撥水効果により吸水状態が形成されず、不透明状態が保持される(前記撥水性樹脂像は透明性であるため、多孔質層の不透明状態が視認される)。従って、常態(非吸水状態)では、判別し難い撥水性樹脂像が、撥水性樹脂像の非配設部分の多孔質層への吸水により判別可能となる。
なお、撥水性樹脂像は平仮名、片仮名、漢字から選ばれる書き順に対応する数字又は記号である。
In the porous layer, a water-repellent resin image is provided in a part of the porous layer and coexisting, and the image shows the order of writing the non-color-changing image selected from hiragana, katakana, and kanji. It functions as a part to be visually recognized.
The water-repellent resin image formed a porous layer water-repellent resin image, although the portion where only the porous layer was formed became transparent or translucent in a state of absorbing liquid such as water and the color tone of the lower layer appeared. The portion is not formed with a water absorption state due to the water repellent effect, and remains opaque (the water repellent resin image is transparent, so the opaque state of the porous layer is visually recognized). Therefore, in a normal state (non-water-absorbing state), a water-repellent resin image that is difficult to be discriminated can be discriminated by absorbing water into the porous layer in the non-arranged portion of the water-repellent resin image.
The water repellent resin image is a number or symbol corresponding to the writing order selected from hiragana, katakana, and kanji.

前記撥水性樹脂像は、シリコン系、パラフィン系、ポリエチレン系、アルキルエチレン尿素系、フッ素系等の撥水性樹脂を含む撥水処理液を印刷、塗布、吹き付け、筆記、或いはスタンプ手段により付着させた後、浸透乾燥して得られ、多孔質層に内在し、共存状態にある撥水性樹脂像を形成できる。
前記撥水性樹脂のうちフッ素系撥水剤が撥水効果及び加工適性の面で効果的であり、固形分として1g/m〜50g/m、好適には、2g/m〜30g/mの範囲の付着量が有効である。
印刷手段としては、スクリーン印刷、グラビヤ印刷、オフセット印刷等を例示でき、特にスクリーン印刷手段は、スクリーンの開孔率、孔径、線径等の調整により、目的に応じた任意の像を比較的簡易に形成でき、撥水性樹脂像の厚み(撥水加工液の塗布量)の調整の面でも効果的である。
The water-repellent resin image was formed by applying a water-repellent treatment liquid containing a water-repellent resin such as a silicon-based, paraffin-based, polyethylene-based, alkylethyleneurea-based, or fluorine-based resin by printing, coating, spraying, writing, or stamping means. Thereafter, a water-repellent resin image obtained by osmotic drying and existing in the porous layer and coexisting can be formed.
Of the water-repellent resins, a fluorine-based water repellent is effective in terms of water repellency and processability, and the solid content is 1 g / m 2 to 50 g / m 2 , preferably 2 g / m 2 to 30 g / An adhesion amount in the range of m 2 is effective.
Examples of the printing means include screen printing, gravure printing, offset printing, and the like. In particular, the screen printing means can relatively easily simplify an arbitrary image according to the purpose by adjusting the aperture ratio, hole diameter, wire diameter, etc. of the screen. It is also effective in adjusting the thickness of the water-repellent resin image (the amount of water-repellent processing liquid applied).

前記教習具は単体の他、複数であってもよいし、複数枚の学習具を綴じ合わせた冊子形態であってもよい。   There may be a plurality of the learning tools, or a booklet form in which a plurality of learning tools are bound together.

前記教習具の具体的な実施形態としては、乾燥状態の教習具の多孔質層に水を付着させて吸水状態とすることにより平仮名等の文字を描いたように視覚させると共に、書き順に対応する数字又は記号が筆跡上に現出する教習具であり、多孔質層が乾燥すると再び元の状態に復する。   As a specific embodiment of the teaching tool, it is made to visually appear as if characters such as hiragana are drawn by attaching water to the porous layer of the teaching tool in a dry state to absorb water, and corresponds to the order of writing. A number or symbol is a learning tool that appears on the handwriting, and when the porous layer dries, it returns to its original state.

支持体及び多孔質層は前記と同様である。
多孔質層上には、平仮名、片仮名、漢字から選ばれる非変色性輪郭像を設けてなる。
前記非変色性輪郭像は、印刷インキにより多孔質層上にスクリーン印刷、オフセット印刷、グラビヤ印刷、コーター、タンポ印刷、転写等の印刷手段により形成して得られる。
