Description

第１の態様において本発明は、
少なくとも一つ以上の（メタ）アクリロイル基を有する化合物（Ａ）、トリアジン型紫外線吸収剤（Ｂ）、並びに分子量が２００〜１０００のシアノアクリレート型紫外線吸収剤（ｃ１）及び分子量が２００〜１０００のベンゾフェノン型紫外線吸収剤（ｃ２）の少なくとも一方である紫外線吸収剤（Ｃ）を含み、質量比で（Ｂ）成分の配合量／（Ｃ）成分の配合量が０．３〜５．０かつ（Ａ）成分１００質量部に対して（Ｂ）成分と（Ｃ）成分の合計が７〜１５質量部である活性エネルギー線硬化性被覆材組成物に関する。 In the first aspect, the present invention provides:
Compounds having one or more (meth) acryloyl groups even without least (A), triazine-type ultraviolet absorber (B), and molecular weight cyanoacrylate type ultraviolet absorbers 200 to 1000 (c1) and molecular weight 200 -1000 benzophenone type ultraviolet absorber (c2) at least one of the ultraviolet absorbers (C2), and (B) component blending amount / (C) component blending amount is 0.3-5. 0 and (a) with respect to 100 parts by weight of component (B) component and (C) total active energy ray-curable coating composition is 7 to 15 parts by weight of components associated.

＜被覆材組成物＞
本発明の被覆材組成物は少なくとも一つ以上の（メタ）アクリロイル基を有する化合物（Ａ）（以下「（Ａ）成分」という）に対し、トリアジン型紫外線吸収剤（Ｂ）（以下「（Ｂ）成分」という）並びに分子量が２００〜１０００のシアノアクリレート型紫外線吸収剤（ｃ１）以下「（ｃ１）成分」）という）及び分子量が２００〜１０００のベンゾフェノン型紫外線吸収剤（ｃ２）（以下「（ｃ２）成分」という）の少なくとも一方である紫外線吸収剤（Ｃ）を含有する。 <Coating material composition>
To the coating material composition of the present invention is one or more of the at no less compound having a (meth) acryloyl group (A) (hereinafter referred to as "component (A)"), preparative triazine type ultraviolet absorber (B) (hereinafter "component (B)" hereinafter) as well as molecular weight cyanoacrylate type ultraviolet absorbers 200 to 1000 (c1) hereinafter "component (c1)") hereinafter) and a molecular weight of the benzophenone type ultraviolet absorber of 200 to 1000 (c2 ) (Hereinafter referred to as “component (c2)” ) is contained in the ultraviolet absorber (C) .

（Ｃ）成分は、分子骨格内にシアノアクリレートを有する（ｃ１）成分及びベンゾフェノン骨格（ｃ２）を有する（ｃ２）成分の少なくとも一方であり、かつ分子量２００〜１０００の紫外線吸収剤である。（Ｃ）成分は単独では十分な耐侯性や密着性などを発現できないが、（Ｂ）成分と併用する事によって、耐侯性を維持しながら、本被覆材組成物を少ない活性エネルギー線で硬化させる事ができるようになる。 (C) component has a cyanoacrylate in molecular skeleton having a component (c1) and benzophenone skeleton (c2) (c2) and less components is also one, and an ultraviolet absorber having a molecular weight of 200 to 1000. Component (C) alone cannot exhibit sufficient weather resistance or adhesion, but when used in combination with component (B), this coating material composition is cured with less active energy rays while maintaining weather resistance. I can do things.

Claims

Compounds having one or more (meth) acryloyl groups even without least (A), triazine-type ultraviolet absorber (B), and molecular weight cyanoacrylate type ultraviolet absorbers 200 to 1000 (c1) and molecular weight 200 -1000 benzophenone type ultraviolet absorber (c2) of at least one ultraviolet absorber (C), the blending amount of (B) component / (C) component is 0.3-5.0 by mass ratio. And the active energy ray-curable coating composition whose sum total of (B) component and (C) component is 7-15 mass parts with respect to 100 mass parts of (A) component .
