Abstract
Description
本発明は、紙、プラスチック、金属等の基材の表面を保護するため塗装を施した化粧シート用に用いられる熱硬化性樹脂組成物を有するコーティング組成物に関する。 The present invention relates to a coating composition having a thermosetting resin composition used for a decorative sheet coated to protect the surface of a substrate such as paper, plastic or metal.
建築物の内外装、家具建具等の表面化粧用に用いられる、紙、プラスチック、金属等の基材の表面には、硬度、耐擦り傷性、耐摩擦性、耐薬品性等の様々な性能を付加し、表面を保護するためにコーティングが行われている。これら化粧シート用コーティング組成物としては、耐擦り傷性、耐摩擦性を向上させる公知の技術としてアルミナ系フィラーを添加する方法が知られている（例えば、特許文献１参照）。しかしながら、アルミナ系フィラーは耐擦り傷性、耐摩擦性は非常に優れているが、過剰にこれらの性能を有するため、接触した物質を必要以上に傷つけてしまうことが問題点としてあげられる。また、アルミナ系フィラーを添加量が多くなるに従って塗膜の透明性が低下し、下地の柄が不鮮明になるなどの問題点があった。 The surface of the base material such as paper, plastic, metal, etc. used for surface decoration of building interiors and exteriors, furniture fittings, etc. has various performances such as hardness, scratch resistance, friction resistance, chemical resistance, etc. A coating is applied to add and protect the surface. As these coating compositions for decorative sheets, a method of adding an alumina filler is known as a known technique for improving scratch resistance and friction resistance (see, for example, Patent Document 1). However, although the alumina filler is very excellent in scratch resistance and friction resistance, since it has these performances excessively, the contacted material is damaged more than necessary. In addition, as the amount of the alumina filler added increases, the transparency of the coating film decreases and the underlying pattern becomes unclear.
本発明の課題は、塗膜の透明性を維持しつつ、耐擦り傷性及び耐摩耗性に優れる表層を有する化粧シート及び該化粧シートに用いるコーティング組成物を提供することにある。 An object of the present invention is to provide a decorative sheet having a surface layer excellent in scratch resistance and abrasion resistance while maintaining the transparency of the coating film, and a coating composition used for the decorative sheet.
本発明者は鋭意検討の結果、熱硬化性樹脂組成物にガラス系フィラーを添加することにより、本発明の目的である塗膜の透明性を維持しつつ、化粧シートの表層の耐擦り傷性及び耐摩耗性を改善することを見出し本発明に至った。 As a result of intensive studies, the present inventors have added glass-based fillers to the thermosetting resin composition, while maintaining the transparency of the coating film, which is the object of the present invention, and the scratch resistance of the surface layer of the decorative sheet and The inventors have found that the wear resistance is improved, and have reached the present invention.
すなわち、本発明は第一に、熱硬化性樹脂組成物及びガラス系フィラーを含有する化粧シート用コーティング組成物であって、該熱硬化性樹脂組成物１００質量部に対して、該ガラス系フィラーを０．１〜２０質量部含有することを特徴とする化粧シート用コーティング組成物を提供する。 That is, the present invention is first a coating composition for a decorative sheet containing a thermosetting resin composition and a glass filler, and the glass filler with respect to 100 parts by mass of the thermosetting resin composition. 0.1-20 mass parts is provided, The coating composition for decorative sheets characterized by the above-mentioned is provided.
本発明は第二に、印刷基材上に、前記した化粧シート用コーティング組成物の硬化皮膜層を有することを特徴とする化粧シートを提供する。 Secondly, the present invention provides a decorative sheet comprising a cured film layer of the coating composition for a decorative sheet described above on a printing substrate.
本発明の化粧シート用コーティング組成物は、透明性を維持しつつ適度な耐擦り傷性および耐摩擦性を有する化粧シートを形成することができる。 The coating composition for decorative sheets of the present invention can form a decorative sheet having appropriate scratch resistance and friction resistance while maintaining transparency.

It can prepare by mixing suitably so that it may become 0.1-20 weight part.
ガラス系フィラーが０．１質量部未満であると、耐擦り傷性、耐摩耗性が充分でなく、２０質量部を越えると、塗膜の透明性が低下し、下地の柄が不鮮明となる傾向が有り好ましくない。 When the glass-based filler is less than 0.1 parts by mass, the scratch resistance and abrasion resistance are not sufficient, and when it exceeds 20 parts by mass, the transparency of the coating film is lowered and the underlying pattern tends to be unclear. There is not preferable.
