Abstract
【解決手段】色素成分がアントラキノン系及び/又はナフタルイミド系色素であるポリマー色素を含有することを特徴とするレーザー光透過性着色樹脂組成物を用いる。
【選択図】なし
Description
従って、本発明の目的は、高いレーザー光透過性を保持しつつ、レーザー溶着に際し、色相の変化が生じることなく、また、溶着物品が他の物品と接触した場合、当該他の物品を汚染することがない着色樹脂組成物を提供することにある。
本発明の着色樹脂組成物は、ポリマー色素とレーザー光を透過する樹脂、特に熱可塑性樹脂からなる。ポリマー色素とは従来の分散染料、昇華性染料、油溶性染料などを高分子量化した色素を意味する。ポリマー色素としては、例えば、アゾ系、アントラキノン系、ナフタルイミド系などの分散染料、昇華性染料、油溶性染料などにビニル基や(メタ)アクリロイル基などの重合性基を導入した色素モノマーを単独でまたは色素構造を有さない通常のビニルモノマーやアクリルモノマーと共重合させたポリマー色素が挙げられる。これらのポリマー色素としては、合成したものでも市販のものでも使用できる。市場から入手できるポリマー色素としては、例えば、DayGlo社から商品名「ジェムトンGC-13Ruby Red」、「ジェムトンGC-17Citrine Yellow」および「ジェムトンGC-19Sapphire Blue」などが挙げられる。
ポリブチレンテレフタレート樹脂に、ポリマー色素(商品名:ジェムトンGC-13Ruby Red、DayGlo社製)、同ジェムトン GC-17Citrine Yellowおよび同ジェムトン GC-19Sapphire Blueをそれぞれ樹脂の0.2%の割合で配合し、押出機にて溶融混練してペレット化し、本発明の着色樹脂組成物とした。該着色樹脂組成物を射出成形機にて2mm厚の着色プレートを作成し、実施例1の評価プレートとした。
ポリブチレンテレフタレート樹脂に、ポリマー色素(商品名:ジェムトン GC-19Sapphire Blue、DayGlo社製)を樹脂の0.2%の割合で配合し、押出機にて溶融混練してペレット化し、本発明の着色樹脂組成物とした。該着色樹脂組成物を射出成形機にて2mm厚の着色プレートを作成し、実施例2の評価プレートとした。
ポリブチレンテレフタレート樹脂に、油溶性染料(商品名:スミプラストエローHLR(Solvent Yellow114)、住友化学製)を樹脂の0.1%の割合および同スミプラストバイオレットB(Solvent Violet13)を樹脂の0.5%の割合で配合し、押出機にて溶融混練してペレット化し、比較例1の着色樹脂組成物とした。該着色樹脂組成物を射出成形機にて2mm厚の着色プレートを作成し、比較例1の評価プレートとした。
ポリブチレンテレフタレート樹脂に、カーボンブラックを樹脂の0.1%の割合で配合し、押出機にて溶融混練してペレット化し、比較例2の着色樹脂組成物とした。該着色樹脂組成物を射出成形機にて2mm厚の着色プレートを作成し、比較例2の評価プレートとした。
ポリブチレンテレフタレート樹脂に、銅フタロシアニンブルーを樹脂の0.2%の割合で配合し、押出機にて溶融混練してペレット化し、比較例3の着色樹脂組成物とした。該着色樹脂組成物を射出成形機にて2mm厚の着色プレートを作成し、比較例3の評価プレートとした。
以上の方法で得られた実施例および比較例の評価プレートについて、色移り性およびレーザー光透過性を、それぞれ下記の方法で評価した結果、下記表1に示す結果が得られた。
各評価プレートと着色されていないポリブチレンテレフタレート樹脂プレートとをそれぞれ重ね合わせ、140℃のオーブンに4時間入れ、着色されていないポリブチレンテレフタレート樹脂プレートが、評価プレートからの色移りにより着色されているか否かを評価した。
○:色移りしていない。
×:色移りしている。
