本発明の表面被覆メタリック顔料に含まれる基体粒子としては、この種のメタリック顔料の基体粒子として用いられるものであれば従来公知の基体粒子をいずれも用いることができ、特に限定されるものではない。このような基体粒子としては、たとえば金属粒子または無機化合物粒子を使用することができる。金属粒子としては、アルミニウム、亜鉛、銅、ブロンズ、ニッケル、チタン、ステンレスなどの金属粒子およびこれらの金属の合金粒子が挙げられる。これらの金属粒子の中でもアルミニウム粒子は金属光沢に優れ、安価な上に比重が小さいため取り扱いやすく、特に好適である。一方、無機化合物粒子としては、ガラス、マイカ、セラミックス粒子(アルミナまたはチタニアなど)等を挙げることができる。
まず、このようなアルミニウム粒子の形状は、特に限定されず、たとえば、粒状、板状、塊状、フレーク状(鱗片状)、などの種々の形状を採用し得るが、塗膜に優れた光輝感を与えるためには、フレーク状であることが好ましい。また、アルミニウム粒子の平均粒径は、通常1~100μm程度が好ましく、より好ましくは3~60μmである。アルミニウム粒子の平均粒径が1μm未満の場合には、本発明の表面被覆メタリック顔料の製造工程における取り扱いが難しく、しかも凝集しやすくなる傾向を示す。一方、該平均粒径が100μmを超えると、塗膜表面が荒れて、好ましい意匠を実現できない場合がある。

本発明の最外層は、被覆層の表面を構成する層であって、1個以上の重合性二重結合を有するモノマーまたはオリゴマーを1種または2種以上重合させてなる第一化合物により構成される。
