Description

금속 증착 전사지 {Transfer metalling paper}Transfer metalling paper {Transfer metalling paper}

본 고안은 개선된 기능을 갖는 금속 증착 전사지에 관한 것으로, 좀더 상세하게는 열경화성 모노머를 주제로하여 PET, OPP로 마련되는 기제필름(BASE FILM)의 표면에 일시 접착성과 박리성을 모두 포함하는 락카층을 착색한 후 금속 증착시킨 다음 수용성 접착제를 도포하여 종이에 열전사시킨 것으로 내/외장 고급 포장지의 재료로 활용되도록 한 금속 증착 전사지에 관한 것이다.The present invention relates to a metal-deposited transfer paper having an improved function, and more specifically, a lacquer including both temporary adhesiveness and peelability on the surface of a base film (BASE FILM) made of PET and OPP based on a thermosetting monomer. The present invention relates to a metal-deposited transfer paper which is thermally transferred onto paper by coloring a layer and then depositing a metal and then applying a water-soluble adhesive to be utilized as a material for high-end packaging materials.

일반적으로, 금속 전사 증착된 포장지는 이형제로서 왁스가 사용되는 관계로 착색된 락카층과의 친화력 불량에 따라 착색제 일부가 필름상에 잔존하게 될 우려가 충분하였고, 45℃이상에서 12∼24시간 정도의 숙성공정을 통해야 하며, 또한 금속층과의 친화력 역시 불량해져 종이 전사시 습윤성과 부착성에 심각한 문제가 발생함은 물론이고 도포속도 역시 매우 느려 생산 및 작업성의 저하를 수반하였다.In general, the metal-transfer-deposited wrapper was sufficiently susceptible to leave a portion of the colorant on the film due to poor affinity with the colored lacquer layer due to the use of wax as a release agent. In addition, the affinity with the metal layer was also poor, causing serious problems in wettability and adhesion during paper transfer, as well as very slow application speed, which accompanied a decrease in production and workability.

아울러, 상기 포장지는 복잡한 제조공정을 거쳐야 했으며, 기제필름의 재활용 곤란과 함께 현저히 낮은 표면 광택도로 인해 품질의 신뢰도가 낮았다.In addition, the wrapping paper had to go through a complicated manufacturing process, and the reliability of the quality was low due to the difficulty of recycling the base film and the remarkably low surface gloss.

따라서, 본 고안은 금속 증착 전사지에 이형제를 별도로 사용하지 않고 하나의 락카층이 이형제와 고광택 표면 코팅제로서의 동시 역할수행이 가능할 수 있도록 기능성 열경화성 모노머를 주제로 제공하여 기제필름과의 우수한 박리성을 도모하고, 락카층의 착색으로 인쇄특성을 향상시키어 기제필름의 재사용 회수를 연장시킴은 물론 수용성이면서도 단시간의 숙성을 갖는 특성으로 종이와의 부착력이 우수하고 종래 60∼80m/min의 도포속도 보다 약 30∼40%가 향상된 80∼120m/min의 도포속도를 유지하는 수용성 방향족 아크릴계 모노머 등을 주제로 하는 에멀젼 접합제가 도포되도록 함으로서 경제성 유지와 공정의 단축 및 품질의 향상을 구현함에 본 고안의 안출된 목적이 있다.Therefore, the present invention provides a functional thermosetting monomer as a theme so that a lacquer layer can simultaneously perform the role of a release agent and a high gloss surface coating agent without using a release agent on a metal deposition transfer paper, thereby achieving excellent peelability with the base film. In addition, the printing property is improved by coloring the lacquer layer to extend the number of times of reuse of the base film, as well as being water-soluble and having a short time of aging, and having excellent adhesion to paper, and about 30 to 60-80 m / min application speed. The object of the present invention is to realize an economical maintenance, a shortening of the process, and an improvement in quality by applying an emulsion binder based on a water-soluble aromatic acrylic monomer, which maintains an application speed of 80 to 120 m / min with an improved rate of -40%. There is this.

상기 본 고안의 목적은 기능성 열경화성 모노머를 주제로 한 가교반응형 수지를 착색시킨 후 PET, OPP필름에 도포하고, 금속 증착시킨 후 이 금속층과 종이와의 양면에 접합성이 양호한 방향족 아크릴계 모노머를 사용한 에멀젼 접합제를 도포하여 피착지인 종이에 건조전 접합 또는 건조후 접합시키는 구성 및 방식을 통해 달성될 수 있다.The object of the present invention is to color a crosslinking reaction resin based on a functional thermosetting monomer, and then apply it to PET and OPP films, and to deposit a metal, and then to an emulsion using an aromatic acrylic monomer having good adhesion to both sides of the metal layer and paper. It can be achieved through the configuration and manner to apply the binder to the paper to be adhered to before bonding or after drying bonding.

이하, 본 고안의 금속 증착 전사지를 첨부도면을 참조로 하여 보다 구체적으로 설명한다.Hereinafter, the metal-deposited transfer paper of the present invention will be described in more detail with reference to the accompanying drawings.

먼저, 본 고안에서 채택되는 기제필름(10)으로는 폴리에스테르계 필름(PET) 혹은 폴리프로필렌계 필름(OPP)이 바람직할 것이며, 이때 해당 필름의 두께로는 10∼30㎛가 요망된다.First, as the base film 10 adopted in the present invention, a polyester film (PET) or a polypropylene film (OPP) will be preferable, and as the thickness of the film, 10 to 30 μm is desired.

이러한 상기 기제필름(10)의 표면으로는 락카층(20)이 1∼2㎛의 두께치와 1.5g/㎡ 정도로 박막 도포되는데, 이때 락카층(20)은 가교반응형 수지와 변성 셀루로스계 수지(니트로셀루로스, 초산셀루로스, 아세테이트 부틸레이트셀루로스 등) 또는 염소화 올레핀탄화수소계 수지(CPP, CPE, PVDC, PVDF수지 등)를 주성분으로 하는 2종 이상의 수지를 케톤계 또는 하이드로카본계 용매에 용해하여 고형분 함량 10∼30% 용액에 소비자가 원하는 색상의 염료를 착색한 상태로서 전술한 바와 같이 박막 도포된 후 120℃에서 약 10∼30초 동안 열풍 건조된다.The lacquer layer 20 is applied to the surface of the base film 10 by a thin film having a thickness of about 1 to 2 μm and about 1.5 g / m 2, wherein the lacquer layer 20 is a crosslinking-type resin and a modified cellulose system. Ketone-based or hydrocarbon-based solvents containing two or more kinds of resins (Nitrocellulose, cellulose acetate, acetate butylate cellulose, etc.) or chlorinated olefin hydrocarbon-based resins (CPP, CPE, PVDC, PVDF resin, etc.) as main components After dissolving in a solid content of 10 to 30%, the dye of the color desired by the consumer is colored as described above, and the thin film is applied as described above, followed by hot air drying at 120 ° C. for about 10 to 30 seconds.

상기 락카층(20)의 외 표면으로는 광택성부여 및 기체투과를 방지하기 위해 약 500Å의 알루미늄, ZnS 진공 증착층(30)과 마이크로 캡슐화 된 방향족 아크릴계 모노머를 주성분으로 하는 수용성 접합층(40)이 순차적으로 도포되는데, 이 수용성 접합층(40)은 금속 증착층(30)과 전술한 락카층(20)과의 침투성 및 친화력이 우수한 카본계를 배합하여 2∼3㎛ 두께로 금속 증착된 기제필름(10)에 도포되어 연질 및 경질 종이로 이루어진 피착지(50)에 건조전 접합 또는 건조후 접합 전사된다는 구성과 작용을 가지며, 이후 기제필름(10)은 전사지와 분리되어 재 사용될 수 있다.The outer surface of the lacquer layer 20 is a water-soluble bonding layer 40 composed mainly of aluminum, a ZnS vacuum deposition layer 30, and a microencapsulated aromatic acrylic monomer to prevent gloss and gas permeation. The water-soluble bonding layer 40 is formed by sequentially depositing a metal layer having a thickness of 2 to 3 μm by combining a carbon system having excellent permeability and affinity between the metal deposition layer 30 and the lacquer layer 20 described above. It is applied to the film 10 has a constitution and function to be bonded before drying or bonded transfer after drying on the adhered paper 50 made of soft and hard paper, the base film 10 can be separated from the transfer paper and reused.

본 고안에 사용된 락카용 가교반응형 수지는 금속 증착층(30)과의 밀착성과 빠른 도포속도를 위해 고형분 함량 10∼20%, 코팅 두께는 1∼2㎛ 정도가 적당할 것인데, 예컨대 그 두께 폭이 크면 수용성 접합제의 침투가 어려워져 종이와의 접착력이 낮아질 우려가 있으며, 또한 건조온도는 80∼160℃ 에서 30초가 요망되는 것이라 할 것인데, 이 역시 온도가 과다하게 높으면 OPP 기제필름(10)의 경우 필름의 내열성이 약해져 변형을 수반함에 기인한다.The crosslinking reaction resin for lacquer used in the present invention may have a solid content of 10 to 20% and a coating thickness of about 1 to 2 μm for adhesion and rapid application speed with the metal deposition layer 30. If the width is large, the water-soluble binder may be difficult to penetrate and the adhesion to the paper may be lowered. Also, the drying temperature is required to be 30 seconds at 80 to 160 ° C. If the temperature is too high, the OPP base film (10 ) Is due to the heat resistance of the film is accompanied by deformation.

한편, 피착지(50)인 종이의 접합층(40)으로 마련되는 방향족 모노머와 아크릴계 모노머 에멀젼 접합제는 그 도포량으로 1.5∼5.0g/㎡가 적당할 것이며, 여기에 첨가되는 속건성형 용매 첨가량은 상기 접합제 사용량의 10% 이하가 적당하고, 접합시 가압 로울러의 온도는 80∼160℃가 적당하다.On the other hand, the aromatic monomer and the acrylic monomer emulsion binder prepared from the bonding layer 40 of the paper to be coated 50 will be 1.5 to 5.0 g / m 2 as the coating amount thereof, and the amount of the quick-drying solvent added thereto is 10% or less of the amount of the binder used is appropriate, and the temperature of the pressurized roller at the time of bonding is suitably 80 to 160 ° C.

본 고안을 구현하기 위해 마련되는 일 실시예를 설명하면 아래와 같다.When explaining an embodiment provided to implement the present invention.

<실시예><Example>

먼저, PET 기제필름(10)에 내후성 안료로 착색된 가교반응형 수지 특히, 우레탄계 폴리에스테르계 수지(OH함량: 15이하, 산가: 10이하) 100부와, 셀루로스계 변성수지 특히, 니트로셀루로스계 수지 5부를 케톤계 용매에 고형분 함량 20% 용액으로 제조한 락카층(20)을 그라비아 또는 리버스코타로 코팅하고, 120℃, 30초 건조한 후 진공 금속 증착층(30)을 도포한 다음 수용성 스틸렌/아크릴계 접합제 100부에 대해 고비점 알콜계 용제인 텍사놀 5부를 혼합한 접합층(40)용액을 그라비아 또는 리버스코타로 상기 기제필름(10)에 코팅하며, 이후 전사종이와의 접합을 위해 120℃, 5m/min의 속도로 기제필름(10)과 피착지(50)를 로울러로 압편한 다음 50℃에서 약 3시간 정도 숙성한 후 필름을 피착지(50)에서 분리하여 재 사용하기 위해 로울러에 감착시키면 오염성없는 필름에 락카층의 표면광택 95, 내마모성 25회의 금속 증착 전사지를 얻게된다.First, 100 parts of a crosslinking reaction resin, especially a urethane-based resin (OH content: 15 or less, acid value: 10 or less), colored with weatherable pigment on the PET base film 10, and cellulose-based modified resin, in particular, nitrocellulose The lacquer layer 20, prepared in 5 parts of a solid content 20% solution in a ketone solvent, was coated with gravure or riverscote, dried at 120 ° C. for 30 seconds, and then coated with a vacuum metal deposition layer 30. A solution of the bonding layer 40 mixed with 5 parts of a high boiling point alcohol solvent, texanol, was coated on the base film 10 with gravure or reversalta, and then 120 for bonding with a transfer paper. The base film 10 and the adhered paper 50 were squeezed with a roller at a speed of 5 m / min, then aged at 50 ° C. for about 3 hours, and then the film was separated from the coated paper 50 to be reused. Locks onto non-contaminated film when adhered to The surface gloss 95 of the car layer and 25 wear-resistant metal-deposited transfer papers are obtained.

따라서, 상기의 구성을 갖는 본 고안은 결국 기제필름에 이형제와 그 위에 락카층이 도포된 종래의 구성과는 달리 락카층이 이형기능과 표면 코팅의 복합적인 기능을 수행함으로 그 제조공정이 단축되고, 기제필름으로 사용되는 PET, OPP필름의 전사 재사용 횟수를 적어도 6회 이상 반복 사용할 수 있게 되어 경제성은 물론 품질의 균일성과 고속인쇄에 따른 생산성의 향상을 기대할 수 있게 된다.Therefore, the present invention having the above-described configuration, unlike the conventional configuration in which the release agent and the lacquer layer is applied to the base film, the manufacturing process is shortened by performing the complex function of the release function and the surface coating. In addition, the PET and OPP films used as base films can be repeatedly used at least six times, thereby improving economics as well as improving productivity due to uniformity and high speed printing.

아울러, 전사된 종이에 기제필름이 남아있지 않아 환경친화적이면서도 자원의 효율적인 재활용 측면에서 그 실시적 가치는 매우 우수하다.In addition, since the base film does not remain on the transferred paper, its practical value is excellent in terms of environment-friendly and efficient recycling of resources.
