Definitions
- the present invention relates to a coated product for applying a coated material to an object such as glue or adhesive.
- the “applied product” is not limited to colorants such as glues, adhesives, pressure-sensitive adhesives, and inks, but is a concept that broadly refers to products for applying oil or other applied products to the target object. .
- One of the above-mentioned coated products is a so-called stick paste (for example, see Non-Patent Document 1).
- This stick paste is housed in a sealed housing in a colored state by mixing a pH indicator with a solid paste exhibiting alkalinity. And after the solid paste in a colored state is applied, the color of the pH indicator disappears, that is, disappears by touching the air.
- Such glue is used because it can be easily identified immediately after application because the applied part can be clearly seen by the user, and the place where the unpainted part can be easily identified as described above.
- there is an advantage that the spot is not conspicuous, and these advantages are a major factor widely used by users.
- a photochromic compound that has a property of being colored when irradiated with light of a specific wavelength and becoming colorless when irradiated with light of another specific wavelength.
- Many of these photochromic compounds have a characteristic that they can be clearly colored by irradiating with ultraviolet light of a specific wavelength and become colorless when irradiated with visible light of a specific wavelength.
- the example using a photochromic compound for writing instruments, such as a marker is known (for example, refer to patent documents 1).
- this photochromic compound is known to have a characteristic of becoming colorless when irradiated with light under natural conditions (see, for example, Patent Document 2), but the spiropyran-based photochromic used in the document is known. Even if the compound is kept in a light-shielded state, the colored state cannot be maintained for a long time and is gradually decolored. For this reason, even if a coated product is produced in a colored state, it is decolored in the subsequent storage / distribution process, and sufficient color development cannot be exhibited.
- the present invention is based on the above-mentioned points, and it is easy to visually recognize the applied portion by stabilizing the sufficiently colored state at the time of use such as after application, and then applied by erasing the color.
- An object of the present invention is to provide a coated product having characteristics that can make a portion inconspicuous.
- the coated product according to the present invention includes a photochromic compound that develops color when irradiated with specific wavelength light having a specific wavelength and becomes colorless when irradiated with visible light or light under natural conditions.
- a coated product comprising a coated product that becomes colored when irradiated and is decolored when irradiated with visible light or light under natural conditions, and a container that stores the coated product, The object is applied to the object in the colored state.
- the coating system according to the present invention includes a photochromic compound that develops color when irradiated with specific wavelength light having a specific wavelength and becomes colorless when irradiated with visible light or light under natural conditions.
- a coating system used for a coated product comprising a coated material that becomes colored when irradiated and becomes decolored when irradiated with visible light or light under natural conditions, and a container that stores the coated material.
- the “decolored state” in the present invention includes not only a completely colorless mode but also a mode of fading so as to approach colorless, and a state in which the fading mode is maintained. It is a concept that also includes
- “light under natural conditions” means light under the conditions of sunlight or indoor light. Specifically, it is light mainly composed of visible light and containing about 5 to 6% ultraviolet light contained in sunlight or a small amount of ultraviolet light contained in a fluorescent lamp. That is, it refers to light containing ultraviolet light at a rate equal to or less than that of sunlight.
- the present invention is not limited to only the coating material before being irradiated by the irradiation unit in a decolored state, but only that the coating material after being irradiated by the irradiation unit is in a colored state. To do.
- the coating is applied in a colored state by the irradiation unit or irradiation means, the unpainted residue of the coating at the time of coating can be more easily visually recognized by the color development of the photochromic compound itself, Since the coated product is in a decolored state under visible light or light under natural conditions, it is possible to provide a coated product that can make the trace of the coated material inconspicuous.
- a photochromic compound is colored when irradiated with ultraviolet light having a specific wavelength, and becomes colorless when irradiated with visible light. It is desirable to do.
- a diarylethene-based photochromic compound is colored when irradiated with ultraviolet light having a specific wavelength and becomes colorless when irradiated with visible light.
- the photochromic compound may be used.
- the photochromic compound becomes colorless when irradiated with light under natural conditions.
- the coated product is added to the photochromic compound by 0.005-5. It is desirable to add 0% by weight, preferably 0.05 to 3.0% by weight, more preferably 0.1 to 1.0% by weight.
- the addition amount of the photochromic compound is lower than 0.005% by weight, the color development due to the color development state hardly appears effectively, and when the addition amount is higher than 5.0% by weight, the visibility in the color development state sufficient to match the increase in the addition amount. This is because improvement tends to hardly appear.
- an ultraviolet absorber may be included in addition to the photochromic compound. In this way, not only the decolored state is effectively maintained, but also recurrent color due to sunlight irradiation can be effectively avoided.
- the coated product is attached to a container and irradiated with the specific wavelength light toward a passing region that passes when the coated material is coated on an object in the container.
- the coated product include an irradiation portion that can be in a colored state.
- the irradiation part is intended to irradiate toward the passage area through which the adhesive immediately before being transferred passes, the color of the coated material may be clearly colored when transferred. it can.
- the irradiation part is attached to the inside of the case, it can also contribute to the compactness of the transfer tool adhesive product itself.
- the coated product is used as a transfer tool, and the coated product is felt in a state where it is detachably applied to a thin film substrate.
- It is an adhesive which comprises a pressure transfer type tape, and the aspect that the irradiation part is attached to the case for transfer tools holding the said pressure sensitive type transfer tape can be mentioned.
- the irradiation unit is a transfer head that supports the substrate when the pressure-sensitive adhesive is pressed against the object and transferred.
- the thing which makes the vicinity irradiate is mentioned. Thereby, it is possible to apply, that is, transfer, the color development state immediately after irradiation and the pressure-sensitive adhesive as the applied product.
- photochromic compounds are known to develop color from the surface side irradiated with light of a specific wavelength, but in order to effectively use the characteristics, the substrate can transmit the light of the specific wavelength. It is desirable that the irradiation unit irradiates the specific wavelength light from the back side of the substrate.

本実施例では、図13に示すように、上記第一実施形態において開示した粘着剤55を実現するために実施例1-1乃至1-23を作成し、それぞれの発色を調査した。発色の調査においてはそれぞれ1級(十分にかなり濃い発色)、2級(十分な発色)、3級(目視で発色が判断できる)、4級(少し発色が弱い)、5級(発色が弱い)及び6級(殆ど発色しない)という6段階評価を行なった。
同図に示すように、これら実施形態は、単体で粘着剤として使用し得るアクリル系エマルションを添加対象物として用い、上記各実施形態で適用されたジアリールエテン系のフォトクロミック化合物である1,2-ビス(2-メチルベンゾ(b)チオフェン-3-イル)ヘキサフルオロシクロペンテン(1,2-Bis(2-methylbenzo(b)thiophen-3-yl)hexafluorocyclopentene)(以下、化合物と記す)をそれぞれ図示の各ジアリールエテン濃度で添加した。化合物を添加する際には、各種溶剤に溶解させるか或いは直接化合物を分散させ、それを添加対象物にミキサー或いはマグネティックスターラーを用いてそれぞれ所定の時間にて混合攪拌を行なった。その後、両面剥離処理を施した厚さ19μmのポリエチレンテレフタレート(PET)フィルムに塗工を行ない、所定の温度及び時間にて熱乾燥させた。なお、ここまでの工程が、塗布物作成工程に該当する。
しかる後に、粘着剤の厚み(のり厚み)を測定した。そしてその後、照射工程に該当するものとして、UVランプを十分に照射し発色状態とした。但しUVランプの照射は発色度合いを評価する便宜上、本実施例では感圧転写式テープに対してでは無く、粘着剤をコピー用紙(コクヨS&T社製 品番:KB-39N)に転写した後、AS ONE Handy Lamp SLUV-4を用い、波長365nmの紫外光を9.0W、0.15Aの出力にて所定時間照射するものとした。
そして実施例1-1~1-11については、発色状態にある粘着剤に可視光を照射した際の、色の消え度合いをも調査した(消え色確認)。具体的には上述のコピー用紙に転写された発色状態にある当該実施例1-1~1-11に対し、その上にさらに同コピー用紙を貼り合わせ、所定のオフィス内デスク上にて蛍光灯下に放置した。この放置された状態で上方から発色度合いを確認し、完全に色が消えた時間をそれぞれ記録した。
実施例1-1~1-11について、ジアリールエテン濃度の違いによる発色の違いについて試験した。その結果、ジアリールエテン濃度が高い程強い発色を示す結果となった。特に添加対象物に対しジアリールエテンを0.05重量%添加した実施例1-3において、目視で発色を判断し得る5級の発色を得た。また実施例1-10、1-11の発色度合いが何れも1級と同程度の発色を示したことから、ジアリールエテンを5重量%以上添加しても、発色にそれ以上の影響がみられないものと考えられる。
また、これら実施例1-1~1-11の色の消え度合いについては、化合物を0.05重量%以下のジアリールエテン濃度で添加した実施例1-1~1-3については殆どすぐに消色が確認された。その一方で、0.1重量%以上のジアリールエテン濃度で添加した各実施例では、ジアリールエテン濃度に比例して色が消えるまでの時間が長くなる傾向を示した。そして最もジアリールエテン濃度が高い10.0重量%添加した実施例1-11については、39分後にして色が消えたことが確認された。
実施例1-12~1-17について、溶剤の種類及び化合物と溶剤とを攪拌させる攪拌時間の違いによる発色の違いについて試験した。その結果、何れの実施例についても化合物を0.5重量%添加している実施例1-7の3級と同じ3級という結果を得た。このことから、溶剤の有無や種類に拘わらず、十分な攪拌を行なえばジアリールエテンは有効に発色し得ることが判った。
実施例1-18及び1-19について、化合物を溶解させる溶剤すなわちアセトンの量の違いによる発色の違いについて試験した。その結果何れも実施例1-4に比べてアセトンの量を増やしたものの、発色には影響が見られなかった。
実施例1-20~1-23について、化合物を溶解させる溶剤すなわちアセトンの量及び添加対象物への攪拌時間の違いによる発色の違いについて試験した。その結果何れも実施例1-7に比べ、発色には影響が見られなかった。
実施例1-24~1-26について、粘着剤塗工後の乾燥時間及び乾燥温度の違いによる発色の違いについて試験した。その結果何れも実施例1-7に比べ、発色には影響が見られなかった。
実施例1-27~1-29について、粘着剤の厚み寸法(のり厚み)の違いによる発色の違いについて試験した。その結果、粘着剤の厚みに比例して発色が強くなるという結果を得た。このことは、厚みに比例して化合物の量が増すことが影響していることが明らかとなった。併せて、上述したUVランプの照射によって、塗工された粘着剤の表面のみならず、厚み寸法における全領域に亘って隈無く発色している点も明らかとなった。
本実施例では、図14に示すように、上記第二実施形態において開示した接着剤55Aを実現するために実施例2-1乃至2-12を作成し、それぞれの発色を調査した。発色の調査においては実施例1同様、それぞれ1級(十分にかなり濃い発色)、2級(十分な発色)、3級(目視で発色が判断できる)、4級(少し発色が弱い)、5級(発色が弱い)及び6級(殆ど発色しない)という6段階評価を行なった。
同図に示すように、これら実施形態は、単体で瞬間接着剤として使用し得る、添加剤を加えていないシアノアクリレート単量体(純粋モノマー)及び市販品であるアロンアルフア(登録商標)・プロ用(ハイスピード)(コニシ株式会社製)アロンアルフア(登録商標)・プロ用(耐衝撃)(コニシ株式会社製)及びアロンアルフア(登録商標)・ゼリー状(コニシ株式会社製)、を添加対象物として用い、上記各実施形態で適用された化合物をそれぞれ図示の各濃度で添加した。化合物を添加する際には、溶剤を用いずにそのまま分散させ、容量5mlのポリプロピレン製カップ内でそれぞれ所定の時間にて混合攪拌を行なった。なお、ここまでの工程が、塗布物作成工程に該当する。
しかる後に、照射工程に該当するものとして、UVランプを十分に照射した。UVランプの照射は、AS ONE Handy Lamp SLUV-4を用い、波長365nmの紫外光を9.0W、0.15Aの出力にて所定距離、所定時間照射するものとした。
実施例2-1~2-4について、添加対象物の違いについて試験した。その結果、何れの実施例についても2級という十分な発色を得た。これは当該化合物か、既存の瞬間接着剤として用いられるものに対し、溶剤を用いなくとも有効に適用し得ることを意味している。
実施例2-5~2-16について、ジアリールエテン濃度の違いによる発色の違いについて試験した。その結果、化合物の濃度が高い程強い発色を示す結果となった。特に、ジアリールエテン濃度と発色については、0.005重量%添加した実施例2-5でもわずかに発色を示し、実施例2-15、実施例2-16の結果から明らかなように、5.0重量%以上のジアリールエテン濃度では変化が見られないほど十分な発色を示している。これらの結果から、上記の第二実施形態への適用を考えれば、好ましくは2~4級の発色を示す実施例2-8~2-13、すなわち、0.1~1.0重量%のジアリールエテン濃度であることが望ましいことが明らかとなった。
実施例2-17~2-19について、化合物を溶解させる際の攪拌方法及び攪拌時間の違いによる発色の違いについて試験した。その結果何れも実施例2-1同様に十分な発色を得た。換言すれば、化合物を溶解させる際の攪拌方法及び攪拌時間の違いによる発色の違いについては影響が見られなかった。
実施例2-20~2-21について、照射工程におけるUVライト照射時の接着剤表面からの照射距離すなわち離間距離と、照射時間の違いによる発色の違いについて試験した。その結果、照射距離を二倍とし、照射時間を半分に短縮した実施例2-21については、目視で発色が判断できるに足る2.5級の発色を示したものの、実施例2-20の2級には及ばなかった。
本実施例では、図15に示すように、上記第一実施形態において開示した粘着剤55を実現するために実施例3-1乃至3-9並びに比較例3-1を作成し、それぞれを上記実施例1同様に発色させたものを可視光を当てて完全に消色させた後、特に紫外光が強い野外に載置し、再発色が起こるか否かを調査した。発色の調査においてはそれぞれ1級(十分にかなり濃い発色)、2級(十分な発色)、3級(目視で発色が判断できる)、4級(少し発色が弱い)、5級(発色が弱い)及び6級(殆ど発色しない)という6段階評価を行なった。本実施例に用いる紫外線吸収剤は、シプロ化成株式会社の製品である「SEESORB 101(2-Hydroxy-4-methoxybenzophenone)」、「SEESORB 102(2-Hydroxy-4-n-octyloxybenzophenone)」及び「SEESORB 701(2-(2-Hydroxy-5-methylphenyl)benzotriazole)」を用いた。

紫外線吸収剤を何も配合していない比較例3-1に関しては、特に紫外光が強い野外で4.5級もの再発色が確認された。それに対し、各実施例では4.5級よりも再発色することが無く、紫外線吸収剤による効果が確認された。特に紫外線吸収剤を1.0重量%混合した実施例3-3、3-6及び3-9については殆ど再発色することは無いとゆう特に良好な効果が確認された。
本実施例では、図16に示すように、上記第二実施形態において開示した接着剤55Aを実現するために比較例4-1及び実施例4-1乃至4-9を作成し、それぞれを上記実施例3同様に発色させたものを可視光を当てて完全に消色させた後、特に紫外光が強い野外に載置し、再発色が起こるか否かを調査した。再発色の調査においては実施例1同様、それぞれ1級(十分にかなり濃い発色)、2級(十分な発色)、3級(目視で発色が判断できる)、4級(少し発色が弱い)、5級(発色が弱い)及び6級(殆ど発色しない)という6段階評価を行なった。
同図に示すように、これら実施例では、単体で瞬間接着剤として使用し得る、添加剤を加えていないシアノアクリレート単量体(純粋モノマー)を添加対象物として用い、上記各実施形態で適用された化合物並びに紫外線吸収剤をそれぞれ図示の各濃度で添加した。化合物を添加する際には、溶剤を用いずにそのまま分散させ、容量5mlのポリプロピレン製カップ内でそれぞれ所定の時間にて混合攪拌を行なった。なお、ここまでの工程が、塗布物作成工程に該当する。
紫外線吸収剤を何も配合していない比較例4-1に関しては、特に紫外光が強い野外で4級もの再発色が確認された。それに対し、各実施例では4.5級よりも再発色することが無く、紫外線吸収剤による効果が確認された。特に紫外線吸収剤を1.0重量%混合した実施例4-3、4-6及び4-9については殆ど再発色することは無いとゆう特に良好な効果が確認された。
