[0003] 近年、シート、包装シート、卵パック、カード、食品、化粧品、トイレタリー用品あるい は医薬品等の各種容器、容器キャップ、電子部品、電子機器、家電、機械部品等の プラスチック樹脂成形物表面への描画は、インクジェット方式が主流である。しかし、 インキの二ジミ、文字の欠け、あるいはインクジェット装置のメンテナンス面において多 くの問題点を抱えていた。一方、描画工程の自動化、無人化を進める動きの中で、 非接触で且つ描画速度の早い、誘導放出光増幅光波による描画方法が普及しつつ ある。
[0004] しかし、樹脂成形物に誘導放出光増幅光波で描画を行っても、誘導放出光増幅光 波が樹脂を透過してしまって描画ができない;誘導放出光増幅光波を樹脂が吸収し ても、照射部の樹脂が溶融または蝕刻するだけで、鮮明な描画ができない;または樹 脂に着色剤を添加しても鮮明に描画が発色しない等、描画の視認性に乏しいという 問題があり、実用性に乏しかった。また、工程管理面において、たとえばその機械読 み取り性の点で不具合を生じてレ、た。
[0005] 上記問題点を解決するため、樹脂成形物に誘導放出光増幅光波による描画を適 用するにあたり、鮮明に黒色発色する発色材料 (光吸収剤)を配合することが検討さ れている。たとえば、含リン酸無機物を含有することを特徴とする材料 (特開平 1一 22 2994号公報)、含ホウ酸無機物を含有することを特徴とする材料 (特開平 1 22299 5号公報)、炭酸銅を含有することを特徴とする材料 (特開平 4 28756号公報)、酸 化ビスマスを含有することを特徴とする樹脂組成物(特開平 4-198366号公報)、水 酸化銅 -リン酸塩または三酸化モリブデンを含有することを特徴とする樹脂組成物( 特開平 3 - 24161号公報)、モリブデン化合物を含有することを特徴とする樹脂組成 物(特開平 11—29711号公報)、アンチモン等によりドープされた二酸化錫で被覆さ れた顔料を含有することを特徴とする樹脂組成物(特表平 10—500149号公報)等が 知られている。これらの材料は、誘導放出光増幅光波を照射したとき、照射部分と未 照射部分で明瞭なコントラストを形成することが、上記それぞれの公報に記載されて いる。
[0006] 上記の各化合物は、誘導放出光増幅光波に対する感度が弱いため、添加量を高 めて描画視認性を確保していた。しかし、添加量を高めると成形物の地肌も着色し、 描画部と成形物地肌とのコントラストが悪くなり、描画の視認性も劣り、実用に適さな レ、という問題が生じていた。特に、高い白色度または透明な成形物に対して少量の 添加量で良好な黒色発色を示すことのできる発色材料は、現状では得られていなか つに。
[0007] 一方、近年、軽量化および低コスト化等の観点より、 自動車分野等における部品の 材質を金属から樹脂に変更することが頻繁に行われている。その際、樹脂成形物の 高生産性化等の観点より、予め複数に分割して成形した樹脂成形物 (樹脂部材)を 互いに接合してひとつの部品とする手段が採られることが多い。
[0008] 従来から、樹脂部材同士の接合に、誘導放出光増幅光波を用いた溶着方法が利 用されている。たとえば、特開昭 60—214931号公報には、誘導放出光増幅光波に 対して透過性のある (非吸収性の)透過性樹脂部材 (非吸収性樹脂部材)と、この誘 導放出光増幅光波に対して吸収性のある吸収性樹脂部材とを重ね合わせた後、誘 導放出光増幅光波を照射することにより、透過性樹脂部材と吸収性樹脂部材との当 接面同士を加熱溶融させて、両者を一体的に接合する方法が開示されている。
[0009] この溶着方法では、透過性樹脂部材内を透過した誘導放出光増幅光波が吸収性 樹脂部材の当接面に到達して吸収され、この吸収された誘導放出光増幅光波がェ ネルギ一として蓄積される。その結果、吸収性樹脂部材の当接面が加熱溶融される とともに、この吸収性樹脂部材の当接面からの熱伝達により、透過性樹脂部材の当 接面も加熱溶融される。この状態で透過性樹脂部材と吸収性樹脂部材の当接面同 士を圧着させれば、両者を一体的に接合することができるのである。
[0010] 上記の溶着方法においては、透過性樹脂部材ゃ吸収性樹脂部材を構成する樹脂 材ゃ誘導放出光増幅光波の種類等により、接合強度に違いがあった。
具体的には、透過性樹脂部材の誘導放出光増幅光波透過率、吸収性樹脂部材の 誘導放出光増幅光波の吸収 *発熱性、または、加熱源として用いる誘導放出光増幅 光波の波長の違い等によって、誘導放出光増幅光波の到達、吸収'発熱および樹脂 部材同士の接合強度が異なっていた。
[0011] さらに上記の溶着方法では、誘導放出光増幅光波の吸収性樹脂部材と非吸収性 樹脂部材とで色調の差があり、樹脂部材の使用用途には制限があった。
具体的には、非吸収性樹脂部材は白色あるいは透明の、誘導放出光増幅光波透 過色であり、吸収性樹脂部材はカーボンブラック、ニグ口シン等の黒色系の、誘導放 出光増幅光波吸収色であるため、このような異なる色の樹脂部材を接合すると、見た 目の違和感が生じるようになり、接合力が弱く感じられるとともに、接合部が目立つと レ、う問題を有していた。
[0012] このような問題を回避するため、特開 2000— 309694号公報、特開 2001— 71384 号公報では、吸収性樹脂部材として、誘導放出光増幅光波を吸収するカーボンブラ ックで黒色に着色した吸収部材を、非吸収性樹脂部材として、誘導放出光増幅光波 を透過する (非吸収性の)染料または顔料を選択して黒色に着色した透過部材を用 レ、ることも提案された。しかし、これらは主に黒色系の成形物に対応したものであり、 その他の有彩色に着色した成形物を得るには、無色あるいは淡色の誘導放出光増 幅光波吸収性染料 ·顔料が必要であった。
たとえば、ィモニゥム系、ナフタロシアニン系色素などの、黒色以外の色相を呈し、 特定領域波長の近赤外線を吸収するような有機色素が存在する。しかし、これらは樹 脂に対する親和性が低ぐまた、耐久性および耐熱性が低いため、エンジニアリング プラスチックス等の熱可塑性樹脂の混練成形カ卩ェ温度では分解してしまレ、、樹脂成 形物に配合する発色材料としては実用上問題があった。
[0013] 一方、これらの有機色素を塗料等に加工し、接合しょうとする 2つの非吸収性樹脂 部材の接合面に塗って、誘導放出光増幅光波を照射することも可能である。これによ り、上記高温カ卩ェでの問題は解決できるが、充分な接合強度が得られず、また使用 できる誘導放出光増幅光波が特定波長に限定されてしまうという問題が残っていた。 さらに、これらの有機色素は極めて高価であるため、工業的に誘導放出光増幅光波 溶着用途として用いることは、経済的に不利であった。

[0023] モリブデンと銅を含む複合金属酸化物(以下、単に「複合金属酸化物」あるいは「M o/Cu複合金属酸化物」と記載する場合もある。)は、可視光から赤外光の広い範囲 で光吸収を示し、特に 800— 1200nmの広い範囲の近赤外線を強く吸収することが でき、光の吸収により発熱する。そして、この複合金属酸化物は、ヘテロポリ酸として の高い酸化力を有する構造であるため、これを樹脂に含ませることにより、近赤外線 照射部分 (描画部分)において樹脂の炭化を促進するとともに、複合金属酸化物自 身が淡色から黒色に変化する。同時に、発熱した複合金属酸化物が樹脂を溶融させ る。
また、上記複合金属酸化物は、それ自身の明度が高く(bright)、淡色であるので、 これを含む樹脂組成物、および、この樹脂組成物を用いて得られる成形物の色相は 淡色であり、よって所望の色相に着色することができる。さらに、上記複合金属酸化 物は耐熱性が高ぐ樹脂の成形温度で変色することがない。
[0024] したがって、この複合金属酸化物を発色材料として含む本発明の誘導放出光増幅 光波用樹脂組成物 (以下、単に「樹脂組成物」と記載する場合もある。)を描画用樹 脂組成物として用い、樹脂組成物または得られる成形品に誘導放出光増幅光波を 照射することにより、極めて黒色度の高い、鮮明な描画を行うことができる。一方、成 形品の未照射 (非描画)部分では、発色材料および樹脂の変色が生じていないため 、地肌の色あるいは透明性がそのまま維持されている。
[0025] 上記描画方法により描画された成形物 (描画成形物)では、誘導放出光増幅光波 の照射部分は鮮明な黒色描画が現れるとともに、非描画部分は影響を受けずに色 相の変化も少ないので、コントラストの高い描画が得られ、視認性も良好である。特に 、写真画像のような精細な画像再現描画や高速描画において、顕著な描画能力を 有する。
[0026] また、この本発明の樹脂組成物に誘導放出光増幅光波を照射することにより樹脂 が溶融するので、本発明の樹脂組成物を加熱溶着用樹脂組成物として用い、その 成形品と他の樹脂部材 (熱可塑性樹脂成形物)とを重ね合わせて、あるいはその成 形品または樹脂組成物を介して他の樹脂部材と別の他の樹脂部材とを重ね合わせ て、誘導放出光増幅光波を照射することにより、他の樹脂部材の樹脂の種類を選ば ずに、両者 (本発明の成形品と他の樹脂部材、あるいは、本発明の成形品または榭 脂組成物を介して他の樹脂部材同士)を溶着 ·接合させることができる。
[0027] 上記溶着方法により溶着'接合された溶着複合成形物 (以下、単に「複合成形物」 という場合もある。)では、溶着性が良好であり、成形物同士 (本発明の成形物と他の 樹脂部材、または、他の樹脂部材同士)の当接面における接合強度が高い。溶着 · 接合させた成形物同士の色調差が小さいので、接合部が目立たなくなり、見た目の 違和感が少ない。さらに、溶着させる成形物の双方に、誘導放出光増幅光波を吸収 しない染顔料を含有させれば、複合成形物を同色に、または任意の色相に着色する ことが可能であり、見た目の違和感が無くなり、所望する色相を得ることが可能である さらに、誘導放出光増幅光波の照射条件によっては、描画と溶着のどちらか一方を 行うだけではなぐ描画と溶着を同時に行うことも可能である。たとえば、誘導放出光 増幅光波の照射条件によっては、溶着箇所を黒色に発色させて視認させることもで き、それにより溶着済みであることが容易に確認できる。
描画と溶着を順次、任意の順序で行うことも、もちろん可能である。

[0034] <モリブデンと銅を含む複合金属酸化物 >
モリブデン (Mo)および銅 (Cu)を含有する Mo/Cu複合金属酸化物は、誘導放 出光増幅光波が照射されるとこれを吸収して発熱し、照射条件により自身が黒色変 化するとともに近接する樹脂を炭化させて、黒色発色させたり、樹脂の溶融を誘発し て接着性を出したりするものである。
複合金属酸化物の体積平均粒径は、下限はサブミクロンオーダーが好ましい。より 低い照射エネルギーで高い効果を得るためには、上限は 4 z m以下が好ましぐ 3 μ m以下がより好ましい。体積平均粒径が小さいことにより、複合金属酸化物の比表面 積が大きくなり、誘導放出光増幅光波を吸収し発熱する能力が高くなるとともに、誘 導放出光増幅光波の吸収ポイントあるいは照射ポイント(ドット)を精密に得ることがで きる。複合金属酸化物の体積平均粒径は、さらに好ましくは 以下、特に好ましく は 1. 以下である。 [0035] ここで、本発明でいう体積平均粒径とは、マイクロトラック粒度分布測定装置 UPA2 50 (日機装 (株))で測定した積算値 50%の粒度のことであり、たとえば、体積平均粒 径 0. 2 /i mは、 d50 = 0. 2 mで示される。

[0039] さらに、本発明で用いられる複合金属酸化物は、少量の添加でも、樹脂組成物の 誘導放出光増幅光波照射箇所の溶着に効果があるため、所望の色相に着色した成 形物 (誘導放出光増幅光波吸収性成形物)、または、着色していない透明なフィルム 成形物 (誘導放出光増幅光波吸収性フィルム成形物)を得て、この誘導放出光増幅 光波吸収性成形物と任意の誘導放出光増幅光波透過性成形物とを接着した複合成 形物、または、この誘導放出光増幅光波吸収性フィルム成形物を介して任意の二つ の誘導放出光増幅光波透過性成形物同士を接着した複合成形物を得ることができ る。

特に本発明の成形物が溶着用途である場合、使用する誘導放出光増幅光波に対 して十分な透過性を示す着色剤を選択することが好ましい。そして、誘導放出光増 幅光波に対する透過性樹脂成形物と吸収性樹脂成形物 (本発明の成形物)とを同色 になるよう調色することにより、これらを溶着させた場合、接合部に違和感のない複合 成形物を得ることができる。

[0057] ぐ成形物への描画方法および描画成形物 >
樹脂組成物からなる 2次元または 3次元成形物の表面、または、樹脂組成物が塗布 等された任意の基材または成形物の表面の所望箇所に誘導放出光増幅光波を照 射することにより、光吸収剤である複合金属酸化物が誘導放出光増幅光波を吸収し 、照射部分に黒色で鮮明な描画がされた描画成形物が得られる。誘導放出光増幅 光波の照射は、描画の目的等に応じてスキャン式、マスク式のいずれで行ってもよい が、細線の描画を高速で行うためにはスキャン式が好ましレ、。
本発明で用いられる複合金属酸化物は、赤外域の光吸収性が高いため、より高い 黒色性を得るためには赤外線の誘導放出光増幅光波を用いることが好ましぐ特に 近赤外線の誘導放出光増幅光波が好ましい。
[0058] 誘導放出光増幅光波の出力、走査速度等の照射条件は、樹脂の種類等に応じて 樹脂が炭化するよう適宜設定可能である。描画用途においては、照射する誘導放出 光増幅光波をレンズにより充分に集光し、スポット径が 100 μ ΐη以下とすることが好ま しぐ 50 /i m以下とすることがより好ましい。スポット径が大きいと、描画の基礎単位で ある 1ドットが大きくなるため、精細な写真画像を得ることが困難となる。また、描画 1ド ット当たりの誘導放出光増幅光波照エネルギーが低くなると、十分な発色度が得られ なくなる場合がある。
[0059] ぐ成形物の溶着方法および複合成形物 >
溶着方法の一例を図 1に示す。誘導放出光増幅光波に対する光透過性樹脂成形 物 (第一樹脂部材) 1と、誘導放出光増幅光波に対する光吸収性樹脂成形物 (第二 樹脂部材;本発明の成形物) 2との、溶着したい箇所を重ね合わせた後、誘導放出光 増幅光波 3を照射する(図 1では 5本のライン状に照射)。すると、照射箇所において 、光吸収性樹脂成形物 2に含まれる複合金属酸化物が、誘導放出光増幅光波を吸 収し発熱して、光吸収性樹脂成形物 2と光透過性樹脂成形物 1との当接面同士をカロ 熱溶融させる。その結果、溶着箇所 5にて両者が一体的に溶着することによって、複 合成形物 6が得られる。なお、図 1では、光透過性樹脂成形物 1側から誘導放出光増 幅光波 3を照射しているが、成形物 2の厚みが非常に薄い場合など、誘導放出光増 幅光波 3が成形物 1と成形物 2の当接面に有効に到達する限りにおいて、光吸収性 樹脂成形物 2側から誘導放出光増幅光波 3を照射することもできる。
[0060] 光透過性樹脂成形物あるいは光透過性樹脂部材とは、誘導放出光増幅光波をほ とんど吸収せずに実質的に透過させる性質を有する熱可塑性樹脂を用いて得られた ものであり、本発明で用いられる複合金属酸化物やその他の光吸収剤を含まないも のである。光透過性樹脂成形物において用いられる樹脂の種類になんら限定はなく 、複合成形物の用途等を考慮して、適宜選択されるが、光透過性樹脂成形物と光吸 収性樹脂成形物とを溶着させるためには、両者に用いられる熱可塑性樹脂の溶融温 度が近接していることが好ましいので、本発明の光吸収性樹脂成形物に用いられた と同じ熱可塑性樹脂を光透過性樹脂成形物にも用いることがより好ましぐ異なる樹 脂を用いる場合は、溶融温度が近接した熱可塑性樹脂を選択することが好ましい。 必要に応じて、前記した光吸収剤以外のその他の成分を樹脂に添加することもでき る。
[0061] 溶着方法の別の一例を図 2に示す。誘導放出光増幅光波に対する光透過性樹脂 成形物(第一樹脂部材) 11と 12とを、溶着したい箇所において、フィルム状に成形し た本発明の成形物 (誘導放出光増幅光波に対する光吸収性樹脂成形物) 22を介し て重ね合わせた後、光透過性樹脂成形物 11または 12のいずれかの側から誘導放 出光増幅光波 3を照射する(図 2では光透過性樹脂成形物 11側から 3本のライン状 に照射)。すると、照射箇所において、光吸収性樹脂成形物 22に含まれる複合金属 酸化物が、誘導放出光増幅光波を吸収し発熱して、光透過性樹脂成形物 11と 12と の当接面同士を加熱溶融させ、溶着箇所 5にて両者を一体的に溶着させて複合成 形物 6が得られる。
[0062] さらに、図には示さないが、上記フィルム状成形物 22の代わりに、本発明の樹脂組 成物を用いて得られた粉体を、光透過性樹脂成形物 11と 12との間に挟んで、同様 に誘導放出光増幅光波 3を照射して、両者を溶着させることができる。あるいは、上 記フィルム状成形物 22の代わりに、本発明の樹脂組成物をそのまま、あるいは塗料 またはインキを調製して、光透過性樹脂成形物 11と 12の当接面に塗布して、同様に 両者を溶着させることができる。
[0063] 本発明で用いられる複合金属酸化物は、近赤外域の光吸収性が高いため、より高 い接着性を得るためには、近赤外域の誘導放出光増幅光波を用いることが好ましい 。一方、多くの樹脂は近赤外域の光に対して透過性を有することから、本発明の複合 成形物は、溶着用途、すなわち誘導放出光増幅光波透過性樹脂成形物用途に有 効である。
但し、溶着用途では、照射する誘導放出光増幅光波による単位面積'単位時間当 たりの照射エネルギーが過乗 ijな場合、樹脂の溶融温度を超え、ャケ、炭化、発泡に 至り、溶着が困難となるため、樹脂の種類等に応じて最適の照射条件を適宜設定す る必要がある。
[0064] 本発明の複合成形物の例としては、上記記載の本発明の成形物における例示と同 じであり、容器、キャップ、パイプ、部品等の 3次元成形物、フィルム、シート、テープ 等の 2次元成形物等が挙げられる。
3次元成形物は、その成形物に応じて射出成形、押し出し成形、中空成形、回転 成形、粉末成形、真空成形等公知の方法で成形される。その具体例としては、 自動 車、電機、電子部品、建設資材等が挙げられる。
[0065] 2次元成形物は、熱可塑性樹脂のフィルム化に用いられるインフレーション力卩ェ、 多層インフレーション力卩ェ、 Tダイフィルム加工、フラットフィルム法による縦横同時二 軸延伸法、または縦横逐次二軸延伸法、チューブフィルム法等の公知の方法で成形 される。このようにして得られた 2次元成形物は食品包装、繊維包装、雑貨包装、薬 品類の包装、テープ、絶縁材料、農業用フィルム、各種シート、各種シール、ラベル、 カード等、通常の熱可塑性樹脂フィルムが用いられる分野と同様の分野で用いられ る。

産業上の利用可能性
[0092] 本発明の誘導放出光増幅光波用樹脂組成物を用いて得られた成形物には、様々 な利用価値がある。
第一に、本発明の樹脂組成物を描画用樹脂組成物として用いることができる。描画 する場合、インクジェット方式と比べて、装置のメンテナンスに伴う負荷が少なレ、。誘 導放出光増幅光波の照射は短時間で充分であり、描画速度が早い。描画は非接触 で行われ、照射部分は鮮明に黒く発色して、描画視認性が高いため、数字、文字な どのテキスト、ロゴ、写真、バーコードなどを施した製品の製造や品質管理等におけ る描画工程の自動化、無人化等にも適用できる。さらに、印刷物に比べ耐久性が高 ぐ改ざんが困難なため、安全性が高い。
第二に、本発明の樹脂組成物は、誘導放出光増幅光波の照射条件によっては、希 釈樹脂を炭化させずに溶融状態に至らしめることができるので、プラスチック成形物 同士を接合させる目的、すなわち加熱溶着用(溶着用)樹脂組成物としても利用でき る。
溶着する場合、たとえば本発明の樹脂組成物から成る成形物を得、これをフィルム 状または粉状に加工し、 2つの誘導放出光増幅光波透過性樹脂部材の間に挟んで 誘導放出光増幅光波を照射することにより、透過性樹脂部材同士を溶着させることも 可能である。
さらに、本発明の樹脂組成物そのものや、本発明の樹脂組成物を用いて製造され た塗料やインキを、樹脂や紙等の基材に塗布または印刷後、誘導放出光増幅光波 照射することにより、基材に描画することゃ基材同士を溶着させることも可能である。 また、本発明の樹脂組成物を描画用かつ溶着用として使用して、描画と溶着を同 時に行うようにすることもできる。たとえば、必要に応じて、溶着箇所を黒色に発色さ せて、溶着箇所を視認させるようにすることもできる。
