Description
본 발명은 광학시트의 제조기술에 관한 것으로, 더욱 상세하게는 동질의 레진조성물을 이용하여 소프트몰드와 레진광학패턴(패턴제품)을 성형하는데 사용할 수 있도록 하면서도 제품물성을 만족하는 광학시트를 제조할 수 있도록 한 동질의 레진조성물을 이용한 광학시트의 제조방법에 관한 것이다.The present invention relates to a manufacturing technology of an optical sheet, and more particularly, to produce an optical sheet that satisfies product properties while being used for molding soft mold and resin optical pattern (pattern product) using a homogeneous resin composition. The present invention relates to a method for manufacturing an optical sheet using a homogeneous resin composition.
일반적으로 광학시트 등을 제조하는 경우 PET필름 등의 베이스기재 상에 제품의 광학특성 향상을 위해 패턴을 형성시키는 공정을 수행하게 되는데, 종래의 패턴형성방식에 있어서는 금속 몰드나 무기물몰드, 미세접촉 프린팅방식 또는 소프트몰딩방식 등이 사용된다.In general, when manufacturing an optical sheet, a process of forming a pattern to improve the optical properties of the product on a base substrate such as PET film is carried out, in the conventional pattern forming method, a metal mold, an inorganic mold, fine contact printing Method or soft molding method is used.
이때, 소프트몰딩방식에는 열경화성 고분자레진에 의한 몰드성형물과 UV경화형 레진에 의한 몰드성형물이 활용되고 있는데, 열경화성 고분자 몰드와는 달리 UV경화형 몰드의 경우는 조성되고 첨가되는 성분(첨가원료)을 통한 표면에너지 변화 를 주어 이형성을 확보함으로써 베이스기재 또는 기판 등의 표면과 균일한 접촉 및 결합력을 제공할 수 있는 장점을 가지고 있을 뿐만 아니라 기존 열경화성 고분자 몰드에서 구현 할 수 없던 미세 패턴구조까지 구현할 수 있다.In this case, mold moldings made of thermosetting polymer resins and mold moldings made of UV-curable resins are used for soft molding. Unlike thermosetting polymer molds, UV-curable molds have a surface that is composed and added (additives). By providing energy change and securing release property, it has the advantage of providing uniform contact and bonding force with the surface of base material or substrate, and also can realize fine pattern structure that could not be realized in the existing thermosetting polymer mold.
그런데, 상술한 UV경화성 몰드의 경우도 단지 UV경화형 레진을 이용한 몰드성형물로서만 사용이 가능할 뿐이고 이 UV경화형 레진을 이용하여 패턴을 형성시키거나 패턴제품을 만드는데 사용하기에는 광학시트나 다른 패턴제품의 광학특성 등 제품물성을 만족시키지 못하는 문제점이 있었다.However, the above-mentioned UV-curable molds can only be used as mold moldings using UV-curable resins, and optical films or other pattern products can be used to form patterns or make pattern products using the UV-curable resins. There was a problem that does not satisfy the product properties such as characteristics.
부연하면, 기존에는 균일한 패턴이외에 비규칙적인 패턴을 형성시키는데 있어서 UV경화형 몰드와 이에 투입하여 패턴을 형성시키고자 하는 패턴형성용 적용레진과의 조성물 차이로 즉, 기존에는 UV경화형 몰드 성형용 레진과 패턴형성용 레진이 각각 다른 종류의 것으로 적용되고 있어 상호간 표면에너지 차이가 발생하므로 인해 완벽한 패턴형성 및 미세패턴을 용이하게 구현하지 못하는 문제점이 있었으며, 균일한 접착력이나 기계적 강도를 형성시키지 못하는 등 제품물성 또한 만족시키기 어려운 문제점이 있었다.In other words, conventionally, in the formation of irregular patterns other than a uniform pattern, the composition is different from the UV curable mold and the resin for forming a pattern to be applied to form a pattern. And resins for pattern formation are applied to different types, so there is a problem in that the perfect pattern formation and fine pattern cannot be easily realized due to the difference in surface energy between each other, and the product does not form uniform adhesive force or mechanical strength. Physical properties also had problems that were difficult to satisfy.
본 발명은 상술한 문제점 등을 감안하여 안출된 것으로서, 동질의 레진조성물을 이용하여 소프트몰드와 레진광학패턴(패턴제품)을 성형하는데 사용할 수 있도록 하면서도 제품물성을 만족하는 광학시트를 제조할 수 있도록 한 동질의 레진조 성물을 이용한 광학시트의 제조방법을 제공하는데 그 목적이 있다.The present invention has been made in view of the above-described problems, and can be used to mold soft molds and resin optical patterns (patterned products) using homogeneous resin compositions, while manufacturing optical sheets that satisfy product properties. It is an object of the present invention to provide a method for manufacturing an optical sheet using a homogeneous resin composition.
본 발명은 동질의 레진조성을 가지고 소프트몰드와 레진광학패턴을 형성시키는데 사용하되, 조성성분에 대한 분자량 조절을 통해 상호간에 이형성을 확보하면서 베이스기재와의 접착력이나 기계적 강도가 우수한 양질의 패턴형성 및 패턴제품을 제조할 수 있도록 한 동질의 레진조성물을 이용한 광학시트의 제조방법을 제공하는데 있다.The present invention is used to form a soft mold and a resin optical pattern having a homogeneous resin composition, while maintaining a release property between the components by controlling the molecular weight of the composition, and excellent pattern formation and pattern of excellent adhesion or mechanical strength with the base substrate The present invention provides a method for manufacturing an optical sheet using a homogeneous resin composition to produce a product.

본 발명은 동질의 레진조성물을 가지고 조성성분에 대한 분자량만을 조절함으로써 기존 소프트 몰드성형물과 레진광학패턴 사이에 형성된 표면에너지 차이를 개선할 수 있게 되며, 이를 통해 소프트 몰드성형물과 레진광학패턴을 갖는 광학제 품을 용이하게 제조할 수 있을 뿐만 아니라 양질이면서 완벽한 패턴 및 미세패턴을 구현할 수 있고 소프트 몰드성형물과 레진광학패턴의 상호간에 이형성을 확보하면서도 레진광학패턴의 기재측 접착력 및 균일도를 높일 수 있음은 물론 기계적 강도 또한 높일 수 있다.The present invention can improve the surface energy difference formed between the existing soft mold molding and the resin optical pattern by adjusting only the molecular weight of the composition with the same resin composition, through which the optical having the soft mold molding and the resin optical pattern Not only can the product be easily manufactured, but also high-quality and perfect patterns and fine patterns can be realized, and the releasability between the soft mold molding and the resin optical pattern can be secured while the adhesive strength and uniformity of the substrate side of the resin optical pattern can be increased. Of course, mechanical strength can also be increased.
본 발명을 첨부한 도면을 참조하여 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
도 1 및 도 2를 참조하여, 본 발명에 의한 동질의 레진조성물을 이용한 광학시트의 제조방법은 UV경화형 레진조성물을 구비한다(S1).
이때, 아크릴기 또는 메타아크릴기를 포함하는 아크릴계, 비닐계, 아릴에스테르계 단량체 중에서 선택된 어느 하나 또는 이들 혼합물로 구성되는 (a)성분과; 상기 (a)성분과 반응성을 갖는 UV경화형 우레탄계 올리고머로 구성되는 (b)성분과; 상기 (a)와 (b) 성분에 첨가되며 불소기나 실리콘기 또는 이 둘을 모두 가지는 반응성 또는 비반응성 화합물로 구성되는 (c)성분 및; 상기 (a) 내지 (c) 성분에 첨가되며 공지의 광중합개시제인 (d)성분으로 이루어지는 UV경화형 레진조성물을 일 예로 들 수 있다.
여기서, 상기 UV경화형 레진조성물은 (a)성분 50~90중량%, (b)성분 10~50중량%, (a)와 (b) 성분의 합 100중량부에 대해 첨가되는 (c)성분 0.01~50중량부 및, (a) 내지 (c) 성분의 합 100중량부에 대해 첨가되는 (d)성분 0.1~50중량부가 조성된 것을 사용할 수 있다.1 and 2, the manufacturing method of the optical sheet using the homogeneous resin composition according to the present invention is provided with a UV curable resin composition (S1).
At this time, (a) component consisting of any one selected from acrylic, vinyl-based, aryl ester-based monomers containing an acrylic group or methacryl group or a mixture thereof; (B) a component consisting of a UV-curable urethane oligomer having reactivity with the component (a); (C) a component added to the components (a) and (b) and composed of a reactive or non-reactive compound having a fluorine group or a silicone group or both; The UV curable resin composition which is added to the said (a)-(c) component and consists of (d) component which is a well-known photoinitiator is mentioned as an example.
Here, the UV-curable resin composition is (c) component 0.01 added to 50 to 90% by weight of the component (a), 10 to 50% by weight of the component (b), 100 parts by weight of the total of the (a) and (b) components What is composed of -50 weight part and 0.1-50 weight part of (d) component added with respect to 100 weight part of sum total of (a)-(c) component can be used.
상기 UV경화형 레진조성물을 이용하여 소프트몰드용 레진(이하 "A레진"이라 한다.)과 패턴형성용 레진(이하 "B레진"이라 한다.)을 각각 조액해낸다(S2).
이때, 조액되는 A레진과 B레진은 성분과 조성비가 같은 동질의 완전 동일한 물질이되, 각 성분들 간의 분자량 차이만을 갖도록 구성되며, 이들 각 레진은 10~500cps의 점도를 갖도록 구성함으로써 레진의 용이한 도포가 가능하게 함이 바람직하다 할 수 있다.The resin for soft mold (hereinafter referred to as "A resin") and the pattern forming resin (hereinafter referred to as "B resin") are prepared by using the UV-curable resin composition (S2).
At this time, the resin A and B to be prepared are completely homogeneous substances having the same composition and composition ratio, but have only a molecular weight difference between the components, and each resin has a viscosity of 10 to 500 cps to facilitate the resin. It may be desirable to enable one application.

여기서, 상기 A레진과 B레진은 제조하는 광학시트의 제품특성에 따라 각 성분별로 10~1000 분자량의 차이를 갖게 할 수 있고 이를 통해 레진에 많은 양의 이형제 성분을 첨가하지 않고도 양자간의 뛰어난 이형성을 갖게 할 수 있으나, 더욱 바람직하게는 500 이내의 분자량 차이로 형성시키는 것이 좋은데 이는 분자량 차이가 클수록 분자량이 큰 쪽으로 경화입자의 덩어리가 커져서 이형성이 떨어지는 단점이 있기 때문이고 분자량 차이가 10 이내로 너무 작게 되면 본 발명의 목적 달성을 위한 이형성을 가질 수 없기 때문이다.Here, the resin A and B resin can have a difference of 10 to 1000 molecular weight for each component according to the product characteristics of the optical sheet to be manufactured, and thereby excellent releasability between both without adding a large amount of release agent component to the resin It is better to have a molecular weight difference of less than 500, but it is better to form a molecular weight difference of less than 500 because the larger the molecular weight, the larger the mass of the hardened particles to the disadvantage that the releasability is lowered, if the molecular weight difference is too small within 10 This is because it cannot have a releasability for achieving the object of the present invention.
