495gのポリプロピレンペレットと、5gの、Dmixture,50値が2.5μmでDmixture,90値が10.5μmの球状アルミニウム粒子と粉体状アルミニウムフレークの混合物(95重量%の球状粒子と5重量%のフレークとからなる)を、タンブラーミキサー中で混合してから、さらなる添加剤を加えることなく、2軸スクリュー押出機(Bersdorff、Germany、直径25mm、28L/D)中、加工温度約230℃で加工して、ペレットとした。次いでこれらのペレットを、射出成形機(Arburg Allrounder 221−55−250)を使用し、その材料に特定の加工温度(たとえば、PP:260℃)で加工して、先に定義した寸法の試験小片を得た。
比較例として、実施例1におけるのと同様ではあるが、ただし球状アルミニウム粒子とアルミニウムフレークとの混合物を添加することなく、PP板を射出成形により成形し、Nd:YAGレーザーを用いて処理した。
Dparticle,50値が39.3μmでDparticle,90値が69.1μm(実施例1の場合と同様にHelos装置を用いて決定)の球状アルミニウム粒子(ECKART GmbH)を、実施例1に従ってポリプロピレン(PP)と共に加工した。
Dflake,50値が4.0μmでDflake,90値が10.0μm(実施例1の場合と同様にHelos装置を用いて決定)の微細なアルミニウムフレーク(PC200、Eckart GmbH、Fuerth、Germany)を、実施例1の場合と同様にしてポリプロピレンと共に加工した。

実施例1の場合と同様にして、銀色の真珠光沢顔料(PX1001、ECKART)を、ポリプロピレン(PP)中、濃度0.49重量%で加工した。この場合、満足ないしは十分なエッジ解像力およびドット精度を示す、高コントラストな、黒く耐摩耗性のマークを得ることが可能であった。しかしながら、この場合においては、PP板が真珠光的光沢を有していて、不透明であった。
実施例1の場合と同様にして、銀色の真珠光沢顔料(PX1001、ECKART)を、ポリプロピレン(PP)中、濃度0.49重量%で、さらに、D10=1.9μm、D50=3.4μm、D90=6μmの粒子サイズ分布を有する亜鉛粉体(亜鉛末17640、製造業者:Norzinko GmbH、Gosslar、Germany)を0.0098重量%で、PPと共に加工した。
実施例1の場合と同様にして、亜鉛粉体(亜鉛末17640、Norzinko GmbH、Gosslar、Germany)を、ポリプロピレン(PP)と共に加工した。
実施例1の場合と同様にして、銀色の真珠光沢顔料(PX1001、ECKART)を濃度0.05重量%で、さらに、亜鉛粉体(亜鉛末17640、Norzinko GmbH、Gosslar、Germany)を0.05重量%の濃度で、PPと共に加工した。
本発明実施例12:
Dparticle,50値が1.6μmでDparticle,90値が3.4μm(Sympatec、Germany製のHelos装置を使用したレーザー粒度測定法により決定)の球状アルミニウム粒子(ECKART GmbH、Fuerth、Germany)と、Dflake,50値が5.0μmのアルミニウムフレーク(Chromal XV、ECKART GmbH、Fuerth、Germany)との混合物(95重量%の球状粒子と5重量%のフレークとからなる混合物(重量比19:1)で、Dmixture,50値が2.5μmでDmixture,90値が10.5μmのもの)を、0.05重量%の割合で、熱可塑性ポリプロピレン(R771−10;DOW、USA)と共に、射出成形プロセルによって加工して板とした(実施例1と同様、面積42×60mm、厚み1mm)。
実施例12の場合と同様にして、その手順を、球状アルミニウム粒子およびアルミニウムフレークを添加していない、熱可塑性ポリプロピレン(R771−10;DOW、USA)製の2枚の板で実施した。しかしながら、それらのプラスチック板の溶融を誘導することは不可能であった。
Dparticle,50値が1.6μmでDparticle,90値が3.4μm(Sympatec、Germany製のHelos装置を使用したレーザー粒度測定法により決定)の球状アルミニウム粒子(ECKART GmbH、Fuerth、Germany)と、Dflake,50値が5.0μmのアルミニウムフレーク(Chromal XV、ECKART GmbH、Fuerth、Germany)との混合物(95重量%の球状粒子と5重量%のフレークとからなる混合物(重量比19:1)で、Dmixture,50値が2.5μmでDmixture,90値が10.5μmのもの)を、0.5重量%の割合で、低密度ポリエチレン(LDPE)(LDPE410−E、DOW、USA)と共に、フィルム押出機(タイプ:Scientific、LabTech、Thailand)により加工して、厚み100μmのインフレートフィルムとした。フィルムの断片(110×70mm)を、球状アルミニウム粒子およびアルミニウムフレークを添加していない、相当するLDPEフィルムで覆い、実施例20の場合と同様に処理した。この結果として、照射された領域において、フィルムとフィルムの接触範囲でそれらの溶融を誘導することが可能であった。その溶着は、力を加えたときにだけ、再分離させることが可能であり、その溶着の部分ではフィルムの破損を伴った。
低密度ポリエチレン(LDPE)(LDPE410−E、DOW、USA)の2枚の顔料無添加のフィルムを使用して、実施例14の手順を繰り返した。しかしながら、ポリマーフィルムの溶融を誘導することは不可能であった。
