Description
この発明は、競技場等の天然芝へのラインマーキングに利用可能な塗料組成物、及び塗料組成物を用いた画線方法に関する。
また、この発明の塗料組成物は、競技場等の天然芝だけではなく、あらゆる天然芝及び人工芝等の塗装に用いることができる。
The present invention relates to a paint composition that can be used for line marking on natural turf in a stadium, and a drawing method using the paint composition.
Moreover, the coating composition of this invention can be used not only for natural turf in stadiums, but also for painting natural turf and artificial turf.
競技場や広場などには天然芝が広く用いられている。これらの天然芝へのラインマーキングには、石灰や炭酸カルシウム等の粉末を散布する方法、合成樹脂製等の白色テープを粘着剤で貼り付ける方法、前記白色テープを固定具によって固定する方法、又は塗料を塗装する方法等が取られていた。 Natural grass is widely used in stadiums and open spaces. For line marking on these natural turf, a method of spraying powder such as lime or calcium carbonate, a method of sticking a white tape made of synthetic resin with an adhesive, a method of fixing the white tape with a fixture, or The method of applying paint was taken.
しかし、白色テープを用いる方法は、競技場におけるスポーツ用のラインマーキングとしては用いることはできない。また、スポーツ用のラインマーキングとして使用可能な石灰や炭酸カルシウム等の粉末を散布する方法は、芝への固着性が悪いために降雨や風、又は人の歩行等によって、前記粉末が流失してしまい、施工されたラインが長持ちしないといった問題点があった。 However, the method using the white tape cannot be used as a line marking for sports in a stadium. In addition, the method of spraying powders such as lime and calcium carbonate that can be used as a line marking for sports is poor adhesion to the turf, so that the powder is washed away by rain, wind, or human walking. As a result, there was a problem that the constructed line did not last long.
そこで、芝への固着性が高く、スポーツ用として利用可能な塗料型のラインマーキング材が求められており、このようラインマーキング材として、特許文献１、及び特許文献２がある。 Therefore, a paint-type line marking material that has high adhesion to turf and can be used for sports is demanded, and as such a line marking material, there are Patent Document 1 and Patent Document 2.
しかし、特許文献１、及び特許文献２のラインマーキング材は、長期的な使用における芝の発育への影響について十分な検討はされていなかった。 However, the line marking materials of Patent Document 1 and Patent Document 2 have not been sufficiently examined for the influence on lawn growth in long-term use.
塗料型のラインマーキング材に酸化チタン等の着色顔料を多く用いた場合には、該ラインマーキング材によって土壌が着色されてしまう現象がみられることがあった。また、前記着色顔料は、石灰や炭酸カルシウム等の粉末を散布するラインマーキング方法に用いられる粉末と比べて粒子径が小さいため、繰り返し使用した場合には、土壌に浸透して凝集し、該土壌の水はけを悪くすることがあった。そして、水はけが悪くなることによって芝の発育に悪影響がみられることがあった。 When many color pigments such as titanium oxide are used in the paint-type line marking material, a phenomenon that the soil is colored by the line marking material may be observed. In addition, since the color pigment has a smaller particle diameter than the powder used in the line marking method for spraying powders such as lime and calcium carbonate, when repeatedly used, the colored pigment penetrates and aggregates in the soil. There was a case where the drainage was bad. And there was a case where the development of turf was adversely affected by poor drainage.
本発明者は、着色顔料としての酸化チタン、有機皮膜形成成分としての酢酸ビニル樹脂エマルション（ガラス転移温度Ｔｇ：２０℃）、溶媒としての水の添加剤からなり、顔料容積濃度（ＰＶＣ）が８５％の塗料組成物によって、天然芝（ケンタッキーブルーグラス）にライン状の塗装を施した。なお、塗料組成物の塗布量は、固形分換算で５０ｇ／ｍ２であった。この塗装は１週間程度で視認性が低下したため、前記塗料組成物を塗装した部分に、再び前記塗料組成物を塗装した。
以上のように１週間毎の再塗装を１２回繰り返した。そして、最後の塗装を行った後に１週間静置して、前記塗料組成物を塗装した部分の状態を観察した。その結果、前記塗料組成物を塗装していた部分の土壌の表面は白色をしており、更に白色の粉状物質が薄い層状に凝集していた。また、前記塗料組成物を塗装した部分の芝は、塗装をしなかった部分の芝に比較すると、発育が悪く、芝の葉の密度に違いが見られた。
The inventor comprises titanium oxide as a color pigment, a vinyl acetate resin emulsion (glass transition temperature Tg: 20 ° C.) as an organic film forming component, and an additive of water as a solvent, and has a pigment volume concentration (PVC) of 85. A natural turf (Kentucky Bluegrass) was painted in a line with a paint composition. The coating amount of the coating composition was 50 g / m 2 in terms of solid content. Since the visibility decreased in about one week, the coating composition was applied again to the portion where the coating composition was applied.
As described above, repainting every week was repeated 12 times. And after performing the last coating, it left still for one week and observed the state of the part which coated the said coating composition. As a result, the surface of the soil where the coating composition was applied was white, and the white powdery substance was agglomerated in a thin layer. In addition, the turf of the portion where the paint composition was applied had poor growth and a difference in the density of turf leaves compared to the turf where the paint composition was not applied.
この発明は、以上に述べたような問題点に着眼してなされたものである。
この発明は、十分な隠ぺい性をもち、芝の発育への影響が少なく、芝への固着性に優れ、且つ繰り返し塗装が可能な芝用塗料組成物を提供することを目的とする。
The present invention has been made with attention to the above-described problems.
An object of the present invention is to provide a turf coating composition that has a sufficient hiding property, has little influence on the growth of turf, has excellent adhesion to turf, and can be repeatedly applied.
本発明の芝用塗料組成物の塗装方法は、着色顔料と体質顔料との含有比率（着色顔料の質量／体質顔料の質量）が２／２〜４／２であり、顔料容積濃度（ＰＶＣ）が６５〜８０％である、着色顔料、体質顔料及び有機皮膜形成成分を含有する芝用塗料組成物の塗装方法であって、
前記着色顔料が酸化チタンであり、前記体質顔料が炭酸カルシウムであり、前記有機皮膜形成成分がエチレン酢酸ビニル樹脂エマルションであり、

Moreover, if the solid content of the diluted turf coating composition is adjusted to 10 to 30% by mass and applied, the turf coating composition can be easily applied.
本発明の芝用塗料組成物について詳細に説明する。
前記芝用塗料組成物とは、天然芝にライン等の標示を描くために用いる塗料組成物である。そのため、該塗料組成物を芝に塗装することによる芝の発育への影響を考慮する必要があり、一般的な塗料にはない技術的課題を有する。
The turf coating composition of the present invention will be described in detail.
The turf coating composition is a coating composition used for drawing a mark such as a line on natural turf. Therefore, it is necessary to consider the influence on the growth of turf by applying the coating composition on the turf, and there is a technical problem not found in general paints.
本発明の芝用塗料組成物は、着色顔料、体質顔料、有機皮膜形成成分、及び溶媒を含有するものである。更に、必要に応じて、その他の添加剤を添加してもよい。 The turf coating composition of the present invention contains a color pigment, an extender pigment, an organic film-forming component, and a solvent. Furthermore, you may add another additive as needed.
そして、本発明の芝用塗料組成物は、顔料容積濃度（ＰＶＣ）が６５〜９０％（さらに望ましくは６５〜８０％）で、且つ前記着色顔料と前記体質顔料との含有比率（着色顔料の質量／体質顔料の質量）が２／２〜４／２（さらに望ましくは２．５／２〜３．５／２）である。なお、前記ＰＶＣとは、前記芝用塗料組成物によって形成される乾燥塗膜の全容積に占める顔料の容積（前記着色顔料の容積と前記体質顔料の容積との和）の割合を百分率で示したものである。 The turf coating composition of the present invention has a pigment volume concentration (PVC) of 65 to 90% (more preferably 65 to 80%), and a content ratio of the color pigment to the extender pigment (of the color pigment). The mass / mass of the extender pigment is 2/2 to 4/2 (more desirably 2.5 / 2 to 3.5 / 2). The PVC is a percentage of the volume of the pigment (the sum of the volume of the color pigment and the volume of the extender pigment) in the total volume of the dry coating film formed by the turf coating composition. It is a thing.
前記ＰＶＣが大きすぎると、前記芝用塗料組成物による乾燥塗膜の芝への固着性が十分ではなく、前記芝用塗料組成物によって形成された乾燥塗膜が芝から剥がれ易くなる。 If the PVC is too large, the turf coating composition will not have sufficient adhesion to the turf of the dried coating film, and the dried coating film formed by the turf coating composition will easily peel off from the turf.
逆に、前記ＰＶＣが小さすぎると、芝の発育に悪影響がみられることがある。なお、芝の発育への悪影響とは、具体的には、芝の発育が悪く、周囲の芝と比較して、芝の葉の密度や、芝の葉や茎の色に違いが見られる現象が生じることである。ＰＶＣが小さすぎる場合に、芝の発育に悪影響がみられるのは、前記芝用塗料組成物に含まれる有機皮膜形成成分の含有率が増えることによって、乾燥塗膜の通気性や透湿性が落ちることや、乾燥塗膜の芝への密着力が強くなりすぎることが原因と思われる。
また、前記ＰＶＣが小さすぎると、芝用塗料組成物によって形成された乾燥塗膜の隠ぺい性が十分でない場合がある。
また、前記ＰＶＣが６５〜８０％であれば、前記芝用塗料組成物は、固着性が特に優れたものとなる。
On the other hand, if the PVC is too small, turf growth may be adversely affected. The adverse effects on turf development are specifically phenomena in which turf growth is poor and there is a difference in turf leaf density and turf leaf and stem color compared to the surrounding turf. Will occur. When PVC is too small, the growth of turf is adversely affected because the content of the organic film forming component contained in the turf coating composition increases and the air permeability and moisture permeability of the dried coating film decrease. This is probably because the adhesion of the dry paint film to the turf is too strong.
Moreover, when the said PVC is too small, the concealment property of the dry coating film formed with the coating composition for turf may not be enough.
Moreover, if the PVC is 65 to 80%, the turf coating composition has particularly excellent adhesiveness.
また、前記含有比率において、前記体質顔料に対する前記着色顔料の比率が小さすぎると、芝用塗料組成物によって形成された塗膜の隠ぺい性が十分でない。 Moreover, in the said content ratio, when the ratio of the said color pigment with respect to the said extender pigment is too small, the concealability of the coating film formed with the coating composition for turf is not enough.
逆に、前記体質顔料に対する前記着色顔料の比率が大きすぎると、前記芝用塗料組成物を同じ位置に繰り返して塗装した場合に、前記芝用塗料組成物を塗装していた部分の土壌の表面が着色顔料によって着色される現象がみられる場合がある。標示を描いた土壌の表面が着色されてしまうと、その標示を消し去ることが困難になる。例えば、多目的な用途に用いられる競技場においては、競技場をある競技で使用するために施工した標示を、競技場を別の競技で使用する際には消去しなければならない。従って、標示の消去が困難になるこのような現象は好ましくない。
また、前記体質顔料に対する前記着色顔料の比率が大きすぎると、芝用塗料組成物を塗装した部分の土壌の水はけが悪くなり、芝の発育に悪影響がみられることがある。
また、前記着色顔料として酸化チタン、黄鉛、亜鉛華、黄色酸化鉄、ベンガラ等の比重の大きい（比重４．０以上）無機顔料を用いた場合では、前記体質顔料に対する前記着色顔料の比率が大きすぎると、前記芝用塗料組成物を長期間貯蔵した場合や、前記芝用塗料組成物を塗装のために希釈したときに、着色顔料が沈降してしまうことがある。
Conversely, if the ratio of the color pigment to the extender pigment is too large, when the turf paint composition is repeatedly applied at the same position, the surface of the soil where the turf paint composition was applied There is a case where the phenomenon of being colored with a coloring pigment is observed. If the surface of the soil on which the sign is drawn is colored, it becomes difficult to erase the sign. For example, in a stadium used for multipurpose purposes, a sign constructed for use in one competition must be erased when the stadium is used in another competition. Therefore, such a phenomenon that makes it difficult to delete the sign is not preferable.
Moreover, when the ratio of the said color pigment with respect to the said extender pigment is too large, the drainage of the soil of the part which apply | coated the turf coating composition may worsen, and a bad influence may be seen on turf growth.
In addition, when an inorganic pigment having a large specific gravity (specific gravity of 4.0 or more) such as titanium oxide, yellow lead, zinc white, yellow iron oxide, or bengara is used as the colored pigment, the ratio of the colored pigment to the extender pigment is If it is too large, the colored pigment may settle when the turf coating composition is stored for a long period of time or when the turf coating composition is diluted for painting.
前記着色顔料としては、酸化チタン、黄鉛、亜鉛華、黄色酸化鉄、ベンガラ、カーボンブラック、カドミウムレッド、モリブデンレッド、クロムエロー、酸化クロム、プルシアンブルー、コバルトブルー等の無機顔料、アゾ顔料、ジケトピロロピロール顔料、ベンズイミダゾロン顔料、フタロシアニン顔料、キナクリドン顔料、イソインドリン顔料、イソインドリノン顔料、スレン系顔料、ペリレン顔料、ペリノン顔料、ジオキサン系顔料等の有機顔料を用いることができる。
なお、前記着色顔料の粒子径は、一般的には０．０１〜０．２４μｍ（「顔料便覧」１９８９年３月１０日（株）誠文堂新光社、日本顔料技術協会編より抜粋）である。
Examples of the color pigment include titanium oxide, yellow lead, zinc white, yellow iron oxide, bengara, carbon black, cadmium red, molybdenum red, chromium yellow, chromium oxide, Prussian blue, cobalt blue and other inorganic pigments, azo pigments, diketo Organic pigments such as pyrrolopyrrole pigments, benzimidazolone pigments, phthalocyanine pigments, quinacridone pigments, isoindoline pigments, isoindolinone pigments, selenium pigments, perylene pigments, perinone pigments and dioxane pigments can be used.
The particle size of the colored pigment is generally 0.01 to 0.24 μm (“Pigment Handbook” March 10, 1989, excerpted from Seibundo Shinkosha, edited by Japan Pigment Technology Association). is there.
前記体質顔料としては、タルク、クレー、カオリン、バリタ、硫酸バリウム、炭酸バリウム、炭酸カルシウム、シリカ粉、アルミナホワイト、珪藻土等を用いることができる。 As the extender pigment, talc, clay, kaolin, barita, barium sulfate, barium carbonate, calcium carbonate, silica powder, alumina white, diatomaceous earth, or the like can be used.
また、前記体質顔料として、粒子径０．５〜３μｍのものを用いることが好ましく、粒子径０．７〜２．５μｍのものを用いることがより好ましく、粒子径０．８〜２．０μｍのものを用いることがより好ましい。
前記粒子径が大きすぎると、前記芝用塗料組成物のＰＶＣ、及び前記着色顔料と前記体質顔料との含有比率を上記した範囲に調整した場合に、前記芝用塗料組成物を芝に塗装して得られる乾燥塗膜の隠ぺい性が十分でない場合がある。
逆に、前記粒子径が小さすぎると、前記芝用塗料組成物を塗装した部分の土壌の水はけが悪くなり、芝の発育に悪影響がみられることがある。
前記粒子径が上記の大きさであれば、隠ぺい性に優れ、芝に悪影響を及ぼさない芝用塗料組成物を得ることができる。
Further, as the extender pigment, one having a particle size of 0.5 to 3 μm is preferably used, more preferably one having a particle size of 0.7 to 2.5 μm, and a particle size of 0.8 to 2.0 μm. It is more preferable to use one.
If the particle size is too large, the turf paint composition is applied to the turf when the turf paint composition PVC and the content ratio of the color pigment to the extender pigment are adjusted to the above ranges. The concealment property of the dried coating film obtained in this way may not be sufficient.
On the other hand, if the particle size is too small, the drainage of the soil where the turf coating composition is applied may worsen, and turf growth may be adversely affected.
When the particle size is the above-mentioned size, a turf coating composition that has excellent concealability and does not adversely affect the turf can be obtained.
前記有機皮膜形成成分としては、アクリル樹脂、スチレン樹脂、ウレタン樹脂、シリコーン樹脂、フッ素樹脂、エポキシ樹脂、メラミン樹脂、アルキッド樹脂、塩化ビニル樹脂、酢酸ビニル樹脂、ポリエステル樹脂などの合成樹脂を単独又は共重合したものを水に分散させた合成樹脂エマルション、又は、ポリビニルアルコール、繊維素エーテル、澱粉、イン化アルキッド樹脂、ポリアクリル酸（塩）、ポリアクリルアミド、水性アクリル樹脂、水性ポリエステル樹脂、水性ポリアミド樹脂、水性ポリウレタン樹脂等の水溶性高分子を用いることができる。また、前記したものに限定されず、一般的な塗料に用いられる有機皮膜形成成分を用いればよい。 As the organic film forming component, synthetic resin such as acrylic resin, styrene resin, urethane resin, silicone resin, fluorine resin, epoxy resin, melamine resin, alkyd resin, vinyl chloride resin, vinyl acetate resin, polyester resin, etc. may be used alone or in combination. Synthetic resin emulsion in which polymerized material is dispersed in water, or polyvinyl alcohol, fiber ether, starch, inked alkyd resin, polyacrylic acid (salt), polyacrylamide, aqueous acrylic resin, aqueous polyester resin, aqueous polyamide resin Water-soluble polymers such as aqueous polyurethane resins can be used. Moreover, it is not limited to the above-mentioned thing, What is necessary is just to use the organic film formation component used for a general coating material.
前記溶媒としては、水、有機溶剤、アルコール類等を用いることができる。しかし、天然芝に塗装した際の芝及び周辺環境の生態への影響を考慮して、前記溶媒が水であることが好ましい。 As the solvent, water, organic solvents, alcohols and the like can be used. However, it is preferable that the solvent is water in consideration of the influence on the ecology of the turf and the surrounding environment when painted on natural turf.
前記添加剤としては、通常の塗料に用いるものを適宜添加することができる。例えば、分散剤、湿潤剤等の界面活性剤、メチルセルロース、ＨＥＣ、ポリアクリル酸、ベントナイト等の増粘剤、成膜助剤、ＰＨ調整剤、消泡剤、防腐剤などを用いることができる。 As said additive, what is used for a normal coating material can be added suitably. For example, surfactants such as dispersants and wetting agents, thickeners such as methylcellulose, HEC, polyacrylic acid, and bentonite, film forming aids, pH adjusting agents, antifoaming agents, preservatives, and the like can be used.
前記芝用塗料組成物の固形分は、３０〜８０質量％であることが好ましく、４５〜６５質量％であることがより好ましい。
前記固形分が少ない場合は、芝用塗料組成物の貯蔵時に、芝用塗料組成物中の体質顔料や着色顔料が芝用塗料組成物中で沈降して凝集し、再分散できなくなってしまう場合がある。また、このように凝集することを防止する為には、芝用塗料組成物に分散剤、増粘剤等の添加剤を大量に添加しなければならない為に、それらの添加剤が、前記有機皮膜形成成分が成膜を阻害する場合がある。また、前記固形分が少ない場合は、固形分が多い芝用塗料組成物に比べて、有効成分（前記溶媒を除いた芝用塗料組成物の成分）の量が同じ場合の組成物の嵩が大きくなってしまうため、運搬、保管の際に扱い難くなってしまう。
逆に、前記固形分が多い場合は、芝用塗料組成物の製造時において、体質顔料や着色顔料を分散させ難くなる。また、芝用塗料組成物の塗装時に、芝用塗料組成物を希釈する場合に、芝用塗料組成物と希釈用の溶媒とを均一に混合するのが容易でない場合がある。
前記固形分が上記の範囲であれば、貯蔵時の安定性に優れ、取り扱い易く、製造が容易であり、希釈が容易である芝用塗料組成物を得ることができる。
The solid content of the turf coating composition is preferably 30 to 80% by mass, and more preferably 45 to 65% by mass.
When the solid content is small, when the turf coating composition is stored, the extender pigments and coloring pigments in the turf coating composition settle and aggregate in the turf coating composition, and cannot be redispersed. There is. Further, in order to prevent such aggregation, it is necessary to add a large amount of additives such as dispersants and thickeners to the turf coating composition. A film-forming component may inhibit film formation. When the solid content is small, the bulk of the composition when the amount of the active ingredient (the component of the turf coating composition excluding the solvent) is the same as that of the turf coating composition with a high solid content. It becomes large and difficult to handle during transportation and storage.
On the other hand, when the solid content is large, it is difficult to disperse the extender pigment and the color pigment during the production of the turf coating composition. Further, when the turf coating composition is diluted at the time of application of the turf coating composition, it may not be easy to uniformly mix the turf coating composition and the solvent for dilution.
When the solid content is in the above range, a turf coating composition having excellent stability during storage, easy handling, easy production and easy dilution can be obtained.
前記芝用塗料組成物を塗装する場合は、芝用塗料組成物を原液のまま用いても良く、前記溶媒を芝用塗料組成物の原液に添加して希釈して用いてもよい。芝用塗料組成物を希釈することによって、塗装時の作業性が向上する。
希釈に用いる溶媒の質量は、通常、芝用塗料組成物の原液の質量の２〜３倍である。希釈後の芝用塗料組成物の固形分を１０〜３０質量％に調整して塗装すれば、芝用塗料組成物を容易に塗装することができる。
When the turf coating composition is applied, the turf coating composition may be used as a stock solution, or the solvent may be added to the stock solution of the turf coating composition for dilution. By diluting the turf coating composition, workability during painting is improved.
The mass of the solvent used for dilution is usually 2 to 3 times the mass of the stock solution of the turf coating composition. If the solid content of the diluted turf coating composition is adjusted to 10 to 30% by mass, the turf coating composition can be easily applied.
前記芝用塗料組成物を塗装する方法としては、通常の塗料の塗装をする方法から適宜選択すればよく、例えば、霧吹き器、噴霧器、アエスガン、エアレズガン等の吹き付け塗装機器、ローラー、刷毛等の一般に用いられる塗装機器や塗装器具を使って塗装すればよい。また、前記芝用塗料組成物と任意の気体とを缶に封入してスプレー缶を作製して、これによって吹き付け塗装してもよい。これらの塗装方法の中でも、芝への塗装方法としては、芝と非接触で塗装が可能な吹き付け塗装であることが好ましい。吹き付け塗装であれば、芝と塗装機器（塗装器具）を接触させずに塗装できるため、塗装によって芝を痛めることがない。 The method for applying the turf coating composition may be appropriately selected from the methods for applying ordinary paints. What is necessary is just to paint using the painting equipment and painting equipment used. Alternatively, the turf coating composition and an arbitrary gas may be enclosed in a can to produce a spray can and sprayed by this. Among these coating methods, the turf coating method is preferably spray coating that allows coating without contact with the turf. With spray painting, you can paint without bringing the turf into contact with the painting equipment (painting equipment), so the turf will not be damaged by painting.
また、前記芝用塗料組成物の塗布量は、該芝用塗料組成物中の固形分換算で、２０〜１３０ｇ／ｍ２であることが好ましく、３０〜１００ｇ／ｍ２であることがより好ましい。
前記塗布量が少なすぎると、芝用塗料組成物の塗膜によって十分な隠ぺい性が得難い。
逆に、前記塗布量が多すぎると、塗膜の隠ぺい性は向上するが、芝の発育に悪影響がみられることがある。また、前記塗布量は一定量までは該塗布量が多いほど隠ぺい性が向上するが、一定量を超えると、塗布量が増えても隠ぺい性は殆ど向上しない場合がある。
Further, the coating amount of the turf coating composition is preferably 20 to 130 g / m 2 , more preferably 30 to 100 g / m 2 in terms of solid content in the turf coating composition. .
If the coating amount is too small, it is difficult to obtain sufficient concealment by the coating film of the turf coating composition.
On the other hand, if the coating amount is too large, the concealment property of the coating film is improved, but the turf growth may be adversely affected. Further, as the coating amount is increased up to a certain amount, the hiding property is improved as the coating amount is increased. However, when the coating amount is exceeded, the hiding property may be hardly improved even if the coating amount is increased.

Evaluation of the adherence of the dried coating film to the turf was performed according to the following procedure.
First, after evaluating the concealment property according to the above procedure, water was applied to a portion of the dry coating film of turf coating composition coated in a line shape having a width of 20 cm and a length of 100 cm using a shower. Sprayed for 1 hour. At this time, the grass was lightly rubbed with a towel 30 minutes, 40 minutes, and 50 minutes after the start of spraying.
Water spraying was stopped and the mixture was allowed to stand for 2 hours for drying, and then the adhesion to turf was evaluated according to the following criteria.
The case where no difference in color was observed between the part where the water was sprayed and the part where the water was not sprayed was indicated as “◯”.
There is a slight color difference between the part where the water was sprayed and the part where the water was not sprayed, and it seems that the dry coating on the part where the water was sprayed was slightly washed away. The thing which did not have a difference was made into "(triangle | delta)".
There is a color difference between the part where the water is sprayed and the part where the water is not sprayed. The thing which was inferior to the visibility of the part which did not spray water was set as "x".
次に、前記手順によって芝への固着性を評価した後、１週間放置した。
次に、１週間放置した乾燥塗膜に水を散布しながら、乾燥塗膜をタオルで軽く擦った。次に、乾燥塗膜を乾燥させた後に、各芝用塗料組成物による乾燥塗膜が施された部分に、該乾燥塗膜と同じ芝用塗料組成物を用いて、上記した方法と同様の方法で、各芝用塗料組成物を再塗装した。
