부착용 방담필름{ANTI-FOGGING FILM FOR ADHERING}Anti-fog film for attachment {ANTI-FOGGING FILM FOR ADHERING}

본 발명은 부착용 방담필름에 관한 것으로, 보다 상세하게는 안경이나 고글 등의 아이웨어(EYE-WEAR)에 재탈부착이 가능하면서도 김서림을 방지할 수 있는 부착용 방담필름에 관한 것이다.The present invention relates to an anti-fog film for attachment, and more particularly, to an anti-fog film for attachment that can be re-attached to eyewear (EYE-WEAR) such as glasses or goggles while preventing fogging.

최근, 라식이나 라섹 등 시력교정수술의 보급으로 시력이 좋지 못한 사람이 전통적으로 착용하던 안경이나 콘택트 렌즈 등을 더 이상 착용하지 않는 사람이 늘어나고 있는 추세이기는 하나, 시력이 좋지 않은 사람의 경우 여전히 안경을 착용하고 활동하게 경우가 대부분이다. 우리나라의 경우 저시력으로 인해 안경이나 렌즈 등 시력교정도구를 착용한 인구비율이 전체 인구의 40% 이상이라는 통계가 있다. 그런데, 안경이나 고글을 착용하고 운동 등 신체활동을 하여 호흡이 가빠져 입김이 과하게 발생하거나 실외에서 건물 내부 등으로 진입시 안경 등의 안팎에 온도차가 발생할 때 안경이나 고글 등의 렌즈 표면에 김서림 현상으로 시야가 악화되어 불편을 느끼는 경우가 발생하고, 특히 겨울 등 실외온도가 낮은 계절에 이러한 현상이 더욱 심해지게 된다. 과거에는 김서림을 방지할 수 있는 성분으로 친수성 폴리머나 계면활성제가 포함된 코팅액 등을 렌즈 표면에 도포하여 등의 방법을 사용하기도 하였으나 이러한 방담 코팅액은 사용 중 쉽게 소실되어 그 효과 지속력이 매우 약해 현재 사실상 사용하는 사람이 없을 정도이다. 따라서, 방담층을 기재상에 코팅한 별도의 방담필름을 미리 또는 사후에 렌즈 등에 형성하기도 한다. 매우 습한 환경에서 어떤 김서림 형성, 즉 지지체 상에 매우 적은 물방울의 응축을 방지하기 위하여, 바람직하게는 50ㅀ 미만, 보다 바람직하게는 25ㅀ미만의, 물과의 낮은 정 접촉각(static contact angle)을 갖는 친수성 코팅을 이러한 지지체의 외곽 표면에 적용하는 것이 제안되었다. 대한민국 특허 제1764280호의 특허공보에는 표면에 실라놀 그룹을 포함하는 코팅 및 이 코팅에 직접 접촉하는 김서림-방지 코팅의 전구체 코팅을 포함하는 기판을 포함하는 안경용 렌즈로서, 김서림-방지 코팅의 전구체 코팅은, 80 개 미만의 탄소 원자를 포함하는 폴리옥시알킬렌 그룹, 및 적어도 하나의 가수분해 가능한 그룹을 갖는 적어도 하나의 실리콘 원자를 포함하는 적어도 하나의 그라프트된 유기실란 화합물을 포함하고, 5 nm 이하의 두께를 가지며, 10ㅀ를 초과하고 50ㅀ미만의 물과의 정 접촉각을 갖는 것을 특징으로 하는 안경용 렌즈가 개시되어 있다. 이러한 영구적인 김서림-방지(anti-fog) 코팅은 김서림(fog)에 대해 스폰지로서 역할을 하고, 투명의 심상(impressure)을 주는 매우 얇은 필름을 형성하여 물방울이 지지체의 표면에 접착하는 것을 가능하게 한다. 이들 코팅은 일반적으로 설포네이트 또는 폴리우레탄과 같은 매우 친수성의 재질로 만들어진다. 그러나, 이러한 코팅은 그 구조상 안경렌즈의 최외측에 코팅이 이루어지게 되는데 최외측에서 충분한 기계적 강도 및 내스크래치성을 갖추지 못하여 렌즈의 교환시기를 당기게 되는 문제가 있다. Recently, due to the widespread use of vision correction surgery such as LASIK or LASEK, more people are no longer wearing glasses or contact lenses that are traditionally worn by people with poor eyesight. Most of the time you wear it and make it active. In Korea, due to low vision, the proportion of people wearing eyeglasses or lenses is more than 40% of the total population. However, when people wear glasses or goggles and perform physical activities such as sports, breathing becomes worse due to excessive breathing, or when the temperature difference occurs inside and outside the glasses when entering the building outdoors, etc. Deterioration of the field of vision may cause discomfort, especially in the season when the outdoor temperature is low, such as winter is more severe. In the past, anti-fog was applied to the surface of the lens by applying a coating solution containing hydrophilic polymer or surfactant, etc. However, the anti-fogging coating solution is easily lost during use and its effect is very weak. There is no one to use. Therefore, a separate anti-fogging film coated with the anti-fogging layer on the substrate may be formed in advance or after the lens. In order to prevent any mist formation in very humid environments, ie condensation of very little droplets on the support, a low static contact angle with water, preferably less than 50 kPa, more preferably less than 25 kPa, It has been proposed to apply a hydrophilic coating having to the outer surface of such a support. Korean Patent No. 1764280 discloses a spectacle lens comprising a substrate comprising a coating comprising a silanol group on its surface and a precursor coating of an antifogging coating in direct contact with the coating, wherein the precursor coating of the antifogging coating is At least one grafted organosilane compound comprising at least one silicon atom having at least one hydrolyzable group, a polyoxyalkylene group comprising less than 80 carbon atoms, and having no greater than 5 nm Disclosed is a lens for spectacles having a thickness of and having a positive contact angle with water of more than 10 mm and less than 50 mm. This permanent anti-fog coating acts as a sponge against the fog and forms a very thin film that gives a transparent impressure, allowing the droplets to adhere to the surface of the support. do. These coatings are generally made of very hydrophilic materials such as sulfonates or polyurethanes. However, this coating has a problem that the coating is made on the outermost side of the spectacle lens due to its structure, which does not have sufficient mechanical strength and scratch resistance at the outermost side, thereby pulling the lens replacement time.

또한, 고글에 별도로 부착하여 사용가능한 방담필름의 예로서 대한민국 특허공개 제10-2017-0129870호에는 요곡면에 대하여 곡면을 따라 휘어진 상태로 부착하는 부착 시트로서, 두께 0.1mm 이상의 폴리카보네이트로 구성되고, 부착되지 않은 상태에서 부착면보다 곡률이 작은 판상의 기판과, 상기 기판의 양면 중, 적어도 상기 요곡면에 부착된 경우에 당해 요곡면과 대향되지 않는 면에 형성된 김서림방지층을 갖는 부착 시트가 개시되어 있다. In addition, as an example of an anti-fogging film that can be separately attached to goggles, Korean Patent Publication No. 10-2017-0129870 discloses an attachment sheet attached to a curved surface in a curved state with respect to a curved surface, and is made of polycarbonate having a thickness of 0.1 mm or more. And an attachment sheet having a plate-shaped substrate having a curvature smaller than an attachment surface in an unattached state, and an anti-fog layer formed on at least one surface of both surfaces of the substrate that is not opposed to the curved surface when attached to the curved surface. have.

그러나, 전술한 문헌을 포함한 종래 친수성 재질로 된 방담시트는 기재 표면에 코팅 후 수분을 지속적으로 흡수하게 되어 과도하게 팽윤 수축되면서 성능을 잃거나 표면 경도 및 강도가 낮아 쉽게 표면이 긁히거나 박리되는 문제가 있어 내구성이 취약한 문제가 있다. 따라서, 친수성 재질에 경화성 재료를 혼입하여 내구성을 개선하려는 시도가 있어 왔다. 대한민국 특허공개 제10-2016-0019537호에는 투명 복합체로서, 기재 층; 및 김서림-방지 층을 포함하고, 상기 김서림-방지 층은 접착성 중합체, 경성 중합체, 및 친수성 중합체를 포함하고, 상기 접착성 중합체, 경성 중합체, 및 친수성 중합체들은 상이하고, 접착성 중합체는 Tg가 약 45 ℃ 미만인 중합체를 포함하고; 경성 중합체는 연필 경도가 ASTM D3363에 따라 측정될 때 적어도 H인 중합체를 포함하고; 친수성 중합체는 골격 및 골격에 공유 결합되는 친수성 분절을 가지는 중합체를 포함한 것을 특징으로 하는 투명 복합체가 개시되어 있다.However, the anti-fogging sheet made of a conventional hydrophilic material, including the above-mentioned document, is continuously absorbed moisture after coating on the surface of the substrate and loses performance due to excessive swelling shrinkage, or the surface is easily scratched or peeled off due to low surface hardness and strength. There is a problem that the durability is weak. Accordingly, there have been attempts to improve durability by incorporating curable materials into hydrophilic materials. Korean Patent Publication No. 10-2016-0019537 discloses a transparent composite, comprising: a substrate layer; And an anti-fog layer, wherein the anti-fog layer comprises an adhesive polymer, a hard polymer, and a hydrophilic polymer, wherein the adhesive polymer, the hard polymer, and the hydrophilic polymers are different, and the adhesive polymer has a Tg of Comprises a polymer that is less than about 45 ° C .; The hard polymer comprises a polymer having a pencil hardness of at least H when measured in accordance with ASTM D3363; A transparent composite is disclosed wherein the hydrophilic polymer comprises a polymer having a backbone and a hydrophilic segment covalently attached to the backbone.

그러나, 상기 문헌을 포함한 종래 투명복합체는 강도 및 경직성이 있어 투명 복합체 자체를 기재에 접착방식으로 부착을 하여야 하고, 기재와의 형태적 정합성이 요구되어 기존의 안경이나 고글에 사용할 수 없는 문제가 있다. However, the conventional transparent composite including the above document has strength and rigidity, so that the transparent composite itself should be attached to the substrate by an adhesive method, and there is a problem in that it cannot be used for existing glasses or goggles due to the conformation of form with the substrate. .

상기 방담층(20)은 친수성 공중합체와 다관능성 모노머를 광개시제 등과 함께 혼합하여 기재(10)상에 소정의 두께로 도포를 한 다음 UV를 쪼여 경화를 하는 방식으로 형성한다. 도 2는 본 발명에 따른 부착형 방담필름(100)의 실시예에 있어 친수성 공중합체와 다관능성 모노머를 반응시켜 경화한 방담층(20)의 형성시 발생하는 화학반응을 설명하기 위한 화학반응식이고, 도 3은 친수성 공중합체와 다관능성 모노머의 경화반응을 도식적으로 도시한 이해도이다. 도 2 및 도 3에서 알 수 있는 바와 같이, 본 발명의 방담필름(100)의 방담층(20)은 친수성을 유지하면서도 가교결합의 존재로 인해 방담층(20) 자체의 팽윤이나 용해현상을 억제하고 치수안정성이 높아 형태유지가 가능하고 내구성 및 내스크래치성 등 장기보전성을 크게 향상시킬 수 있다. 상기 방담층(20)을 구성하는 친수성 공중합체와 다관능성 모노머는 몰비로 1: 0.01 내지 1 범위로 배합되는 것이 바람직하다. 상기 친수성 공중합체와 다관능성 모노머의 비가 0.01 미만이면 가교화의 정도가 낮아 수분과 접촉시 방담층(20)의 용해나 팽윤 등을 방지하기 어려워 형태유지 및 내구성이 낮아지는 문제가 있고, 반면 상기 성분비가 1을 초과하는 경우 친수성이 낮아 방담성능이 저하될뿐더러 재질의 경화로 인해 유연성이 떨어져 안경이나 고글 렌즈 표면에 밀착이 어려워지는 문제가 발생할 수 있기 때문이다.The anti-fogging layer 20 is formed by mixing a hydrophilic copolymer and a polyfunctional monomer together with a photoinitiator and the like to apply a predetermined thickness on the substrate 10 and then cure UV rays. Figure 2 is a chemical reaction equation for explaining the chemical reaction that occurs in the formation of the anti-fogging layer 20 cured by reacting a hydrophilic copolymer and a polyfunctional monomer in the embodiment of the adhesive anti-fogging film 100 according to the present invention 3 is a schematic diagram illustrating the curing reaction of a hydrophilic copolymer and a polyfunctional monomer. As can be seen in Figures 2 and 3, the anti-fogging layer 20 of the anti-fogging film 100 of the present invention suppresses swelling or dissolution of the anti-fogging layer 20 itself due to the presence of crosslinking while maintaining hydrophilicity. It has high dimensional stability and can maintain shape and greatly improve long-term integrity such as durability and scratch resistance. The hydrophilic copolymer and the polyfunctional monomer constituting the anti-fogging layer 20 are preferably blended in a molar ratio of 1: 0.01 to 1. When the ratio of the hydrophilic copolymer and the polyfunctional monomer is less than 0.01, the degree of crosslinking is low, so that it is difficult to prevent dissolution or swelling of the antifogging layer 20 when in contact with moisture, resulting in low shape retention and durability. If the component ratio exceeds 1, the hydrophilicity is low, the anti-fogging performance is lowered, and the hardening of the material may cause a problem that it is difficult to adhere to the glasses or goggles lens surface due to the flexibility.

본 발명의 부착형 방담필름(100)은 상기 기재(10) 타측면 외주연부상에 형성된 점착층(30)을 포함한다. 본 발명의 부착형 방담필름(100)의 경우 김서림 방지를 위한 방담층(20)은 방담필름이 부착되는 렌즈의 최외측으로 드러나도록 위치하여야하기 때문에 상기 점착층(30)은 렌즈와의 접촉면, 즉 방담층(20)이 형성되는 기재(10) 일면의 반대측에 형성되어야 하며, 또 대부분의 점착제는 통상 굴절율이 기재(10)나 렌즈와 상이하여 시야가 닿지 않는 그 외주연부상에 형성되어 안경 등 착용자가 본 발명의 부착형 방담필름을 렌즈에 부착하는 경우 그 존재를 인지하지 못하도록 하는 것이 바람직하다. 또한, 전술한 바와 같이 본 발명의 부착형 방담필름(100)은 그 내구성이 우수하여 재사용이 가능하도록 상기 점착층(30)은 재부착성을 갖는 재질인 것이 바람직하다. Attachable anti-fogging film 100 of the present invention includes a pressure-sensitive adhesive layer 30 formed on the outer peripheral portion of the other side of the substrate (10). In the case of the antifouling anti-fogging film 100 of the present invention, the antifogging layer 20 for antifogging should be positioned to be exposed to the outermost side of the lens to which the antifogging film is attached, so that the adhesive layer 30 is in contact with the lens. That is, the anti-fogging layer 20 should be formed on the opposite side of one surface of the substrate 10, and most adhesives are usually formed on the outer periphery of which the refractive index is different from the substrate 10 or the lens so that the field of view does not reach the glasses. When the wearer attaches the attachment type anti-fogging film of the present invention to the lens, it is preferable not to recognize the presence of the wearer. In addition, as described above, the adhesive anti-fogging film 100 of the present invention is excellent in durability and the adhesive layer 30 is preferably made of a material having re-adhesion so that it can be reused.
