Description

本発明は、硬化塗膜の形成方法および硬化塗膜を有する物品に関する。 The present invention relates to a method for forming a cured coating film and an article having the cured coating film.

放射線硬化性樹脂を硬化させた硬化塗膜を有する物品としては、印刷が施された基材フィルムの印刷面上に硬化塗膜を形成した化粧シート；印刷が施された基材の印刷面上に硬化塗膜を形成した化粧板；基材フィルム上に赤外線遮蔽機能を有する硬化塗膜を形成した赤外線遮蔽フィルム；基材フィルム上に硬化塗膜を形成した水圧転写フィルム；木質基材上に硬化塗膜を形成した木質材等が知られている。該硬化塗膜は、基材上に放射線硬化性塗料を塗布して塗膜を形成し、該塗膜に放射線を照射し、塗膜を硬化させることによって形成される。 As an article having a cured coating film obtained by curing a radiation curable resin, a decorative sheet having a cured coating film formed on a printed surface of a substrate film on which printing is performed; on a printed surface of a substrate on which printing has been performed Decorative plate with a cured coating formed on it; Infrared shielding film with a cured coating having an infrared shielding function on a substrate film; Hydraulic transfer film with a cured coating formed on a substrate film; On a wooden substrate A wood material or the like on which a cured coating film is formed is known. The cured coating film is formed by applying a radiation curable coating on a substrate to form a coating film, irradiating the coating film with radiation, and curing the coating film.

該硬化塗膜には、耐汚染性（防汚性、耐薬品性、耐酸性、耐アルカリ性等。）、耐磨耗性等が要求される。よって、放射線硬化性塗料としては、これらの特性に優れた硬化塗膜を形成できる、放射線硬化性シリコーン化合物を含む放射線硬化性塗料が用いられる（例えば、特許文献１〜５）。 The cured coating film is required to have stain resistance (antifouling property, chemical resistance, acid resistance, alkali resistance, etc.), abrasion resistance, and the like. Therefore, as the radiation curable coating material, a radiation curable coating material including a radiation curable silicone compound capable of forming a cured coating film excellent in these characteristics is used (for example, Patent Documents 1 to 5).

しかし、放射線硬化性シリコーン化合物を含む放射線硬化性塗料からなる硬化塗膜は、耐酸性、耐アルカリ性に優れているものの、防汚性、耐薬品性が不充分であり、食品（カレー等。）、インキ等によって着色されたり、有機溶剤によって表面が変化する問題を有する。該問題は、放射線硬化性シリコーン化合物がシリコーン変性ウレタン（メタ）アクリレートまたはシリコーン（メタ）アクリレートの場合に特に顕著になる。 However, a cured coating film comprising a radiation curable coating containing a radiation curable silicone compound is excellent in acid resistance and alkali resistance, but has insufficient antifouling and chemical resistance, and food (such as curry). There is a problem that the surface is colored by an ink or the like, or the surface is changed by an organic solvent. This problem becomes particularly remarkable when the radiation curable silicone compound is a silicone-modified urethane (meth) acrylate or silicone (meth) acrylate.

硬化塗膜の耐汚染性を向上させる方法としては、下記方法が考えられる。
（ｉ）硬化塗膜中のシリコーン化合物の量を増やす方法。
（ii）硬化塗膜表面にシリコーンコート剤を塗布する方法。
しかし、（ｉ）の方法では、硬化塗膜の透明性が低下する問題がある。（ii）の方法では、工程数が増え、高コストとなる問題がある。

(I) A method of increasing the amount of the silicone compound in the cured coating film.

（硬化塗膜を有する物品）
硬化塗膜２２を有する物品１０としては、耐汚染性および耐磨耗性が要求される物品、例えば、壁紙；家具、浴室、台所、家電製品（エアコン、テレビ、冷蔵庫等。）等の化粧シートまたは化粧材；自動車用の内装材；光ディスク等の保護層；ディスプレイ（液晶ディスプレイ等。）の保護フィルム等が挙げられる。 (Articles with cured coating)
As the article 10 having the cured coating film 22, an article requiring contamination resistance and abrasion resistance, for example, wallpaper; furniture, bathroom, kitchen, decorative sheet for home appliances (air conditioner, television, refrigerator, etc.) Or a decorative material; an interior material for automobiles; a protective layer such as an optical disk; a protective film for a display (liquid crystal display, etc.).

以上説明した硬化塗膜の形成方法によれば、放射線硬化性シリコーン化合物を含む放射線硬化性塗料を塗布して形成された塗膜１４の表面を、シリコーン処理面１６を有する剥離基材２０で、シリコーン処理面１６が塗膜１４に接するように覆った状態で、塗膜１４に放射線を照射し、塗膜１４を硬化させて硬化塗膜２２を形成しているため、耐汚染性、耐磨耗性、および透明性に優れる硬化塗膜２２を形成できる。この理由は、以下のように考えられる。 According to the method for forming a cured coating film described above, the surface of the coating film 14 formed by applying a radiation curable coating containing a radiation curable silicone compound is the release substrate 20 having the silicone treated surface 16. In a state where the silicone-treated surface 16 is in contact with the coating film 14, the coating film 14 is irradiated with radiation, and the coating film 14 is cured to form a cured coating film 22. A cured coating film 22 having excellent wear and transparency can be formed. The reason is considered as follows.

剥離基材２０のシリコーン処理面１６を塗膜１４に接させることにより、塗膜１４に含まれるシリコーン化合物が、剥離基材２０のシリコーン処理面１６に向かって配向し、塗膜１４の表層付近にシリコーン化合物が集中する。この状態で塗膜１４を硬化させることにより、硬化塗膜２２の表層付近にシリコーン化合物を集中させることができ、硬化塗膜２２の耐汚染性および耐磨耗性が良好となる。また、硬化塗膜２２の表層付近にシリコーン化合物を集中させることができるため、シリコーン化合物の量を減らすことができ、硬化塗膜２２の透明性が良好となる。 By bringing the silicone-treated surface 16 of the release substrate 20 into contact with the coating film 14, the silicone compound contained in the coating film 14 is oriented toward the silicone-treated surface 16 of the release substrate 20, and near the surface layer of the coating film 14. The silicone compound concentrates on the surface. By curing the coating film 14 in this state, the silicone compound can be concentrated in the vicinity of the surface layer of the cured coating film 22, and the contamination resistance and wear resistance of the cured coating film 22 are improved. Moreover, since a silicone compound can be concentrated on the surface layer vicinity of the cured coating film 22, the quantity of a silicone compound can be reduced and the transparency of the cured coating film 22 becomes favorable.

また、以上説明した硬化塗膜の形成方法によれば、従来のようにシリコーンコート剤を塗布する工程が不要となるため、硬化塗膜２２を低コストで形成できる。 Moreover, according to the formation method of the cured coating film demonstrated above, since the process of apply | coating a silicone coating agent conventionally becomes unnecessary, the cured coating film 22 can be formed at low cost.
