この点を以下に説明する。

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、隠蔽性が大きくなるものと推察される。
又、多孔質像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。
On the support, a porous image having a low refractive index pigment fixed to a binder resin in a dispersed state and having different transparency between a liquid absorbing state and a non-liquid absorbing state is provided.

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).
This point will be described below.
Silicic acid is produced as amorphous amorphous silicic acid, and depending on its production method, the dry method using a gas phase reaction such as thermal decomposition of silicon halide such as silicon tetrachloride and the decomposition by acid such as sodium silicate. It is roughly classified into those by a wet method using a liquid phase reaction such as.
The structure of the dry process silicic acid and that of the wet process silicic acid are different, 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, the wet process silicic acid has a rough molecular structure compared to the dry process silicic acid, so when applying the wet process silicic acid, the wet process silicic acid is superior in the diffused reflection of light in the dry state compared to the system using the dry process silicic acid, It is presumed that the concealment will increase.
In addition, since the porous image absorbs water, the wet method silicic acid has more hydroxyl groups present as silanol groups on the particle surface than the dry method silicic acid, and has a high degree of hydrophilicity. It is done.

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、形成される多孔質像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、前記多孔質像内部への水の浸透性が悪くなる。
前記多孔質像は、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、前記樹脂が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。
尚、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、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、前記多孔質像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重量％以上含有させることが好ましい。

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 image to be formed. When exceeding, the water permeability into the porous image is deteriorated.
Since the porous image 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 in which the resin is emulsified and dispersed in water, or a colloid in which the resin is self-emulsified without the need for an emulsifier by an ionic group of the ionic urethane resin (urethane ionomer) itself and dissolved or dispersed in water. A dispersion type (ionomer type) urethane resin can also be used.
The urethane-based resin may be either an aqueous urethane-based resin or an oil-based urethane-based resin, but an aqueous urethane-based resin, particularly a urethane-based emulsion resin or a colloidally dispersed urethane-based resin is preferably used.
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 the 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 weight or more in the binder resin of the porous image.
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 permeation time into the porous image, the degree of permeation, and the slow speed of drying after permeation can be adjusted. Furthermore, the said adjustment can be controlled by adding a dispersing agent suitably.
A colorant may be contained in the porous image.

更に、窒素吸着比表面積が５００〜１５００ｍ２／ｇのカーボンブラックを用いると、従来のカーボンブラック（空隙率が２０％以下）のカーボンと比較して１／２〜１／３程度の添加量で同等の導電性能が得られると共に、バインダー樹脂への分散性能に優れるため、安定した導電機能を有する導電性印刷像が得られる。
前記カーボンブラックとしては、中空シェル状構造のカーボンブラック、或いは、内部が疎の凝集体からなるカーボンブラックが好適に用いられる。
The conductive material contained in the conductive printed image, the carbon black click is used.
Among the carbon blacks, carbon black having a porosity of 50 to 80% is added in an amount of about 1/2 to 1/3 compared to carbon of conventional carbon black (porosity is 20% or less). Since equivalent conductive performance can be obtained, the amount of binder resin added can be increased. Therefore, it is excellent in applicability to a support having flexibility, for example, cloth, and a conductive printed image having excellent washing strength and scratch resistance compared to ink using conventional carbon black can be obtained.
Furthermore, when carbon black having a nitrogen adsorption specific surface area of 500 to 1500 m 2 / g is used, the addition amount is about ½ to 〜 compared with carbon of conventional carbon black (porosity is 20% or less). Since the equivalent conductive performance is obtained and the dispersion performance in the binder resin is excellent, a conductive printed image having a stable conductive function can be obtained.
As the carbon black, a carbon black having a hollow shell-like structure or a carbon black composed of an agglomerated sparse inside is preferably used.

In the state where the water is attached, blue is visually recognized, but when the water evaporates, it returns to the original white again.
An energization actuating device was attached to the energizing water color changing body to obtain an energizing water color changing device.
Each energized print image of the energized water discoloration device is provided with an element of an energization actuating device that emits light when energized, and does not operate in a normal state (non-liquid-absorbing state). When an electroconductive printed image is connected by attaching water to the porous image between the panda and the panda pattern using an applicator that can store water therein, the energized light is emitted.
Moreover, since the porous image to which water has adhered changes from white to blue, the handwriting can be clearly recognized.
Since the handwriting returns to its original state by drying, the handwriting can be played over and over again, and it was useful as an educational toy having handwriting formation and a light emitting function.
実施例２
実施例１で作製した通電性水変色装置と、水付着手段として水を内部に収容可能な塗布具を組み合わせて通電性水変色セットを得た。
前記通電性水変色セットは、実施例１と同様に水の適用により何度も繰り返し遊ぶことができた。
Example 2
The electroconductive water discoloration device produced in Example 1 was combined with the applicator capable of containing water as water adhering means to obtain an electroconductive water discoloration set.
The electroconductive water discoloration set was able to be repeated many times by applying water in the same manner as in Example 1.
