Description
以下、本発明の熱転写シートと被転写体との組合せについて、図面を参照しながら説明する。なお、本発明は多くの異なる態様で実施することが可能であり、以下に例示する実施の形態の記載内容に限定して解釈されるものではない。また、図面は説明をより明確にするため、実際の態様に比べ、各部の幅、厚さ、形状等について模式的に表される場合があるが、あくまで一例であって、本発明の解釈を限定するものではない。また、本願明細書と各図において、既出の図に関して前述したものと同様の要素には、同一の符号を付して、詳細な説明を適宜省略することがある。後述する本発明の印画物の形成方法、及び熱転写シートについても同様である。
本開示の実施の形態に係る熱転写シートと被転写体との組合せ(以下、一実施形態の組合せと言う場合がある)に用いられる熱転写シートは、図1に示すように、基材1の一方の面に、不可視光線吸収材料含有層2、第1転写層(5)、色材層3が面順次に設けられた構成を呈している。基材1、不可視光線吸収材料含有層2、第1転写層(5)、色材層3は、一実施形態の組合せに用いられる熱転写シート10における必須の構成である。
基材1についていかなる限定もされることはなく、熱転写シートの分野で従来公知のものを適宜選択して用いることができる。一例としては、グラシン紙、コンデンサー紙またはパラフィン紙等の薄紙、ポリエチレンテレフタレート、ポリエチレンナフタレート、ポリブチレンテレフタレート、ポリフェニレンサルファイド、ポリエーテルケトンもしくはポリエーテルサルホン等の耐熱性の高いポリエステル、ポリプロピレン、ポリカーボネート、酢酸セルロース、ポリエチレン誘導体、ポリ塩化ビニル、ポリ塩化ビニリデン、ポリスチレン、ポリアミド、ポリイミド、ポリメチルペンテンまたはアイオノマー等のプラスチックの延伸または未延伸フィルムが挙げられる。また、これらの材料を2種以上積層した複合フィルムも使用することができる。
図1に示すように、基材1の一方の面(図示する形態では基材1の上面)には、第1転写層(5)、色材層3と面順次に不可視光線吸収材料含有層2が設けられていている。不可視光線吸収材料含有層2は、必須の成分として不可視光線吸収材料を含有している。本願明細書で言う不可視光線吸収材料とは、赤外光や紫外光等を吸収する材料を意味する。一実施形態の組合せによれば、熱転写シート10と、被転写体100とを重ね合わせ、被転写体100上に不可視光線吸収材料含有層2を溶融転写することで、被転写体100上に、赤外光下或いは紫外光下で認識可能な画像50Aを形成することができる(図6参照)。また、不可視光線吸収材料含有層を、可視光を吸収せず、或いは殆ど吸収せず、赤外光や紫外光等を吸収する不可視光線吸収材料を含有する不可視光線吸収材料含有層とすることもできる。この場合、熱転写シート10と、被転写体100とを重ね合わせ、被転写体100上に不可視光線吸収材料含有層2を溶融転写することで、被転写体100上に、可視光下では視認することができない、或いは視認しにくく、赤外光下或いは紫外光下で認識可能な画像50Aを形成することができる。以下、不可視光線吸収材料を含有する画像のことを「特別画像」と言う場合がある。
不可視光線吸収材料含有層2の転写性(離型性)を向上させるべく、基材1と不可視光線吸収材料含有層2との間に、離型層(図示しない)を設けることもできる。なお、離型層は、不可視光線吸収材料含有層2を被転写体100上に移行させるときに、基材1側に残る層である。離型層の材料としては、例えば、シリコーンワックス等の各種ワックス類、シリコーン樹脂、シリコーン変性樹脂、フッ素樹脂、アクリル樹脂、ポリビニルアルコール樹脂等の水溶性樹脂、セルロース誘導体樹脂、ウレタン系樹脂、酢酸系ビニル樹脂、アクリルビニルエーテル系樹脂、無水マレイン酸樹脂等の各種樹脂等やこれらの混合物等を挙げることができる。離型層の厚みは、通常、0.5μm以上5μm以下の範囲内である。
図1に示すように、基材1上には、上記不可視光線吸収材料含有層2、色材層3と面順次に第1転写層(5)が設けられている。第1転写層(5)は、基材1から剥離可能に設けられており、熱転写によって、特別画像50Aが形成された被転写体100上に転写される(移行する)層である。
受容層5Aの材料について特に限定はないが、色材層3が含有する昇華性染料が染着し易いバインダー樹脂を用いることが好ましい。このようなバインダー樹脂としては、ポリプロピレン等のポリオレフィン系樹脂、ポリ塩化ビニル、ポリ塩化ビニリデン等のハロゲン化樹脂、ポリ酢酸ビニル、ポリアクリルエステル等のビニル系樹脂、ポリエチレンテレフタレート、ポリブチレンテレフタレート等のポリエステル系樹脂、ポリスチレン系樹脂、ポリアミド系樹脂、エチレンやプロピレン等のオレフィンと他のビニル系モノマーとの共重合体、アイオノマー、セルロース系樹脂等を挙げることができる。受容層5Aは、これらのバインダー樹脂の1種を単独で含有していてもよく、2種以上を含有していてもよい。また、これらバインダー樹脂の2種以上を共重合してなる共重合体を用いることもできる。中でも、セルロース系樹脂は、転写界面に位置する層である受容層5Aの転写性を十分に満足させることができ、熱転写シート10に印加されるエネルギーを高めていった場合であっても、受容層5Aを含む第1転写層(5)の転写性を満足させることができる点で受容層5Aの材料として好ましい。また、塩化ビニル-酢酸ビニル共重合体は、受容層5Aの染料染着性や、受容層5Aと色材層3との離型性を高めることができる点で、受容層5Aの材料として好ましい。
被転写体100と第1転写層(5)との密着性を向上させるべく、図2に示すように、第1転写層(5)を、基材1側から受容層5A、ヒートシール層5Cをこの順で積層してなる積層構成とすることもできる。ヒートシール層5Cの材料としては、被転写体100との接着性が良好な材料が好ましい。このような材料としては、例えば、エチルセルロース、酢酪酸セルロース等のセルロース誘導体、ポリスチレン、ポリα-メチルスチレン等のスチレン共重合体、ポリメチルメタクリレート、ポリエチルメタクリレート、ポリエチルアクリレート等のアクリル系樹脂、ポリ塩化ビニル、ポリ酢酸ビニル、塩化ビニル-酢酸ビニル共重合体、ポリビニルブチラール等のビニル系樹脂、ポリエステル樹脂、ナイロン樹脂、エポキシ樹脂、ポリウレタン樹脂、アイオノマー、エチレン-アクリル酸共重合体、エチレン-アクリル酸エステル共重合体等の合成樹脂や、粘着付与剤としてのロジン、ロジン変性マレイン酸樹脂、エステルゴム、ポリイソブチレンゴム、ブチルゴム、スチレンブタジエンゴム、ブタジエンアクリルニトリルゴム、ポリアミド樹脂、ポリ塩素化オレフィン等を挙げることができる。ヒートシール層5Cの厚みは、0.1μm以上20μm以下の範囲が好ましい。
図2に示すように、受容層5Aとヒートシール層5Cとの間に、プライマー層5Bを設けることもできる。プライマー層5Bを設けることで、受容層5Aとヒートシール層5Cとの密着性の向上、受容層5Aと色材層との離型性の向上を図ることができ、また、受容層5A上に形成された熱転写画像に生じ得る滲みの抑制や、帯電防止性を付与することができる。
図1に示すように、基材1の一方の面には、上記不可視光線吸収材料含有層2、第1転写層(5)と面順次に色材層3が設けられている。一例としての色材層3は昇華性染料を含有しており、一実施形態の組合せにより形成される熱転写画像がモノカラーである場合には、図1に示すように適宜選択した1色の層のみ形成してもよいし、所望の画像がフルカラー画像である場合には、図2に示すように、イエローの昇華性染料を含有するイエロー色材層3Y、マゼンタの昇華性染料を含有するマゼンタ色材層3M、シアンの昇華性染料を含有するシアン色材層3Cを、基材1の同一面に面順次に繰り返し形成してもよい。また、イエロー色材層3Y、マゼンタ色材層3M、シアン色材層3Cのうちの2つの色材層を設けた構成としてもよい。
基材1と色材層3との間に、基材1と色材層3との密着性の向上を目的とする染料プライマー層(図示しない)を設けることもできる。
図2に示すように、基材1の一方の面に、上記不可視光線吸収材料含有層2、第1転写層(5)、色材層3とともに、保護層7Aを含む第2転写層(7)を面順次に設けることもできる。第2転写層(7)は、保護層7Aのみからなる単層構成を呈していてもよく、図2に示すように、基材1側から剥離層7B、保護層7Aがこの順で積層されてなる積層構成を呈していてもよい。また、これ以外の構成を呈していてもよい。
保護層7Aを構成するバインダー樹脂としては、例えば、ポリエステル樹脂、ポリエステルウレタン樹脂、ポリカーボネート樹脂、アクリル樹脂、紫外線吸収性樹脂、エポキシ樹脂、アクリルウレタン樹脂、これらの各樹脂をシリコーン変性させた樹脂、これらの各樹脂の混合物、活性光線硬化性樹脂等を挙げることができる。なお、活性光線とは、活性光線硬化性樹脂に対して化学的に作用させて重合を促進せしめる光線を意味し、具体的には、可視光線、紫外線、X線、電子線、α線、β線、γ線等を意味する。
第2転写層(7)の転写性を向上させるべく、第2転写層(7)を、基材1側から剥離層7B、保護層7Aがこの順で積層されてなる積層構成とすることもできる。剥離層7Bを構成するバインダー樹脂としては、例えば、エチルセルロース、ニトロセルロース、酢酸セルロースなどのセルロース誘導体、ポリメタクリル酸メチル、ポリメタクリル酸エチル、ポリアクリル酸ブチルなどのアクリル系樹脂、ポリ塩化ビニル、塩化ビニル-酢酸ビニル共重合体、ポリビニルブチラールなどのビニル共重合体の熱可塑性樹脂や、飽和又は不飽和ポリエステル樹脂、ポリウレタン樹脂、熱架橋性エポキシ-アミノ樹脂、アミノアルキッド樹脂などの熱硬化型の樹脂、シリコーンワックス、シリコーン樹脂、シリコーン変性樹脂、フッ素樹脂、フッ素変性樹脂、ポリビニルアルコール等を挙げることができる。また、第2転写層(7)の箔切れ性の向上を図るべく、剥離層7Bに、マイクロシリカやポリエチレンワックスなどのフィラーを含有させてもよい。また剥離層は、上記に例示した樹脂に加えイソシアネート化合物等の架橋剤、錫系触媒、アルミニウム系触媒等の触媒を用いて形成することとしてもよい。
また、基材1の他方の面に背面層(図示しない)を設けることもできる。なお、背面層は、一実施形態の組合せで用いられる熱転写シート10における任意の構成である。
以上、一実施形態の組合せに用いられる熱転写シートとして、基材1の一方の面に、不可視光線吸収材料含有層2、第1転写層(5)、色材層3が面順次に設けられた構成の熱転写シートを中心に説明を行ったが、上記構成の熱転写シートにかえて、以下の熱転写シートの組合せを、被転写体と組合せる熱転写シートとしてもよい。

上記で作成した熱転写シート、及び被転写体を下表1に示す組合せとし、各実施例、及び比較例の組合せとした。なお、後述する印画物の形成方法で形成した被転写体上に特別画像が形成されてなる積層体と、被転写体との色差(ΔE*ab)が10以下となる組合せを実施例とし、色差(ΔE*ab)が10を超える組合せを比較例としている。なお、色差(ΔE*ab)は、分光測定器(i1 X-rite社)を使用して、測色した。
<不可視光線吸収材料含有層を含有する画像(特別画像)の形成>
下表1の組合せにより、下記テストプリンターを用いて、被転写体上へ、不可視光線吸収材料含有層を溶融転写し特別画像を形成した。特別画像の厚さは1.0μmであった。
サーマルヘッド:KEE-57-12GAN2-STA(京セラ(株))
発熱体平均抵抗値:3303(Ω)
主走査方向印字密度:300(dpi)
副走査方向印字密度:300(dpi)

ライン周期:1.5(msec./line)
印字開始温度:35(℃)
パルスDuty比:85(%)
上記テストプリンターを用いて、上記で形成した特別画像上に、受容層の転写を行った。
上記テストプリンターを用い、上記で転写した受容層上に、128/256階調のグレー画像を形成し、各実施例、及び比較例の印画物を得た。
各実施例、及び比較例の組合せにより形成した各実施例、及び比較例の印画物を目視で確認し、特別画像のコードパターンを認識することができたか否かを、下記の評価基準に基づいて評価した。評価結果を表1に併せて示す。
A:予め特別画像の位置を知っている人が見ても、その位置、形状を認識することができなかった。
B:予め特別画像の位置を知っている人が見ると、その位置、形状を認識することができたが、知らない人が見た場合、その位置、形状を認識できなかった。
NG:予め特別画像の位置、形状を知らない人が見ても、その位置、形状を認識することができた。
カラーセンサー(CZ-H35S キーエンス(株))にて、各実施例、及び比較例の組合せで用いている熱転写シートの不可視光線吸収材料含有層を、各色材層(イエロー色材層、マゼンタ色材層、シアン色材層)、及び保護層と区別して検知できるかどうかを、以下の評価基準に基づいて評価した。評価結果を表1に併せて示す。
