Description
본 발명은, 경화물에 있어서의 우수한 경도, 내찰상성(耐擦傷性), 및 기재밀착성을 갖는 활성 에너지선 경화성 수지 조성물, 상기 활성 에너지선 경화성 수지 조성물로 이루어지는 경화물, 적층체, 및 물품에 관한 것이다.The present invention relates to an active energy ray-curable resin composition having excellent hardness, scratch resistance, and substrate adhesion in a cured product, a cured product comprising the active energy ray-curable resin composition, a laminate, and an article. it's about
(메타)아크릴로일기를 갖는 수지 재료는, 자외선 조사 등에 의해 용이하게 또한 순시에 경화시킬 수 있으며, 또한, 경화물의 투명성이나 경도 등이 우수하므로, 도료나 코팅제 등의 분야에서 널리 사용되고 있다. 그 도공 대상물은 광학 필름이나 플라스틱 성형품, 목공품 등 다방면에 걸쳐 있어, 도공 대상물의 종류나 용도 등에 따라서 요구 성능도 다양하므로, 목적에 따라서 설계된 수지가 다수 제안되어 있다.A resin material having a (meth)acryloyl group can be easily and instantaneously cured by ultraviolet irradiation or the like, and since the cured product has excellent transparency and hardness, it is widely used in the fields of paints and coatings. The coating object spans various fields, such as an optical film, a plastic molded article, a woodwork object, and since the required performance also varies according to the kind, use, etc. of a coating object, many resins designed according to the objective have been proposed.
(메타)아크릴로일기를 갖는 수지 재료로서는, (메타)아크릴로일기 함유 아크릴 수지, 펜타에리트리톨테트라아크릴레이트, 및 펜타에리트리톨트리아크릴레이트를 함유하는 활성 에너지선 경화형 수지 조성물이 알려져 있다(예를 들면, 특허문헌 1 참조). 상기 특허문헌 1에 기재된 활성 에너지선 경화형 수지 조성물은 경화물에 있어서의 표면 경도와 저경화수축성의 밸런스가 우수하므로, 비교적 얇은 플라스틱 필름을 도공 대상으로 하는 코트제로서 유용하다. 그러나, 필름 기재에의 밀착성, 특히 고온 습윤 조건 하에서의 장기 보존 후의 밀착성이 낮아, 벗겨짐이 발생하기 쉬운 과제가 있었다. 또한, 아크릴계의 기재는 일반적으로 코팅제와의 밀착성이 부족한 기재(난밀착성 기재)로서 알려져 있지만, 이 특허문헌 1에 있어서도, 아크릴 필름에서의 평가는 이루어져 있지 않으며, 실제로 밀착성이 실용 레벨에 이르지는 못했다.As a resin material having a (meth)acryloyl group, an active energy ray-curable resin composition containing a (meth)acryloyl group-containing acrylic resin, pentaerythritol tetraacrylate, and pentaerythritol triacrylate is known (e.g. For example, refer to patent document 1). Since the active energy ray-curable resin composition described in Patent Document 1 has an excellent balance between the surface hardness and low curing shrinkage in the cured product, it is useful as a coating agent for coating a relatively thin plastic film. However, the adhesiveness to a film base material, especially the adhesiveness after long-term storage under high temperature and wet conditions was low, and there existed a subject which peeling was easy to generate|occur|produce. In addition, although an acrylic base material is generally known as a base material (non-adhesive base material) lacking in adhesiveness with a coating agent, also in this patent document 1, evaluation in an acrylic film is not made|formed, and adhesiveness did not actually reach a practical level. .
아크릴 필름은 디스플레이 부재나, 자동차 부재, 건재(建材) 용도에 폭넓게 사용되고 있다. 예를 들면, 디스플레이 부재의 하나인 편광판은 편광 소자를 투명한 보강 필름의 사이에 끼운 적층 필름으로 이루어져 있고, 종래 보강 필름에는 트리아세틸셀룰로오스 필름이 사용되어 왔지만, 최근, 트리아세틸셀룰로오스 필름 대신에, 보다 염가이며 입수가 용이한 아크릴 필름을 사용하는 기술이 제안되고 있다. 또한, 경량화가 진행하는 자동차 부재에서는 금속으로부터 수지에의 시프트에 수반하여, 내외장용의 톱코트 필름에 아크릴 필름이 채용되고 있다. 이 외에, 도금 대체나 도장 대체 등, 투명성이나 광택을 살린 다양한 용도를 들 수 있다.Acrylic films are widely used for display members, automobile members, and building materials. For example, a polarizing plate, which is one of the display members, consists of a laminated film sandwiching a polarizing element between transparent reinforcing films. Conventionally, a triacetyl cellulose film has been used as a reinforcing film, but recently, instead of the triacetyl cellulose film, A technique using an inexpensive and easily available acrylic film has been proposed. Moreover, with the shift from a metal to resin in the automobile member which weight reduction advances, an acrylic film is employ|adopted as a topcoat film for interior and exterior use. In addition, various uses, such as plating replacement and painting replacement, are mentioned which made use of transparency and luster.
아크릴 필름용의 하드코트제로서, 예를 들면, 테트라히드로푸르푸릴아크릴레이트, 스테아릴메타크릴레이트, 및 아크릴 수지를 함유하는 활성 에너지선 경화형 조성물이 알려져 있지만, 아크릴 필름과의 밀착성은 시장 요구 레벨을 충족시키는 것은 아니었다(예를 들면, 특허문헌 2 참조).As a hard coat agent for an acrylic film, for example, an active energy ray-curable composition containing tetrahydrofurfuryl acrylate, stearyl methacrylate, and an acrylic resin is known. was not satisfied (for example, refer to Patent Document 2).
그래서, 아크릴계 기재 등의 난밀착성 기재에 대해서도 우수한 밀착성을 가지며, 또한, 코팅제로서 사용 가능한 경도, 및 내찰상성이 우수한 재료가 요구되고 있었다.Accordingly, there has been a demand for a material having excellent adhesion to a non-adhesive substrate such as an acrylic substrate, and excellent in hardness and scratch resistance that can be used as a coating agent.
본 발명이 해결하려고 하는 과제는, 경화물에 있어서의 우수한 경도, 내찰상성, 및 기재밀착성을 갖는 활성 에너지선 경화성 수지 조성물, 상기 활성 에너지선 경화성 수지 조성물로 이루어지는 경화물, 적층체, 및 물품을 제공하는 것이다.The problem to be solved by the present invention is an active energy ray-curable resin composition having excellent hardness, scratch resistance, and substrate adhesion in a cured product, a cured product comprising the active energy ray-curable resin composition, a laminate, and an article. will provide
