Description
본 발명은 전사 필름 및 그의 제조방법에 관한 것으로, 보다 상세하게는 ⅰ) 수지층, ⅱ) 이형층 및 ⅲ) 인쇄층으로 이루어지는 가공목재 피복용 전사 필름 및 그의 제조방법에 관한 것이다.BACKGROUND OF THE INVENTION Field of the Invention The present invention relates to a transfer film and a method for producing the same, and more particularly, to a transfer film for processing wood coating comprising a resin layer, ii) a release layer, and a printing layer, and a method for producing the same.
열전사 필름은 주로 중밀도 섬유판 (Medium Density Fiberboard; 이하 "MDF"라 약칭함)과 같은 기판에 피복되어 무늬를 형성하는데 사용되어 왔다. 가구부품으로 천연목재 그 자체를 사용하면 천연목재 고유의 무늬가 그대로 나타나며 필요에 따라 다양한 요철무늬로 조각하여도 무늬가 그대로 유지되어 아름다운 입체무늬를 가진 가구부품을 제조할 수 있었다. 그러나 가구의 수요는 급증하는 반면 목재의 공급은 극히 제한되어 있는 실정이므로 천연목재가 아닌 가공목재로서도 천연목재 고유의 무늬를 나타낼 수 있는 가구부품 등을 만드는 기술이 개발되어 왔다.Thermal transfer films have been mainly used to form patterns by coating on substrates such as Medium Density Fiberboard (abbreviated as "MDF"). When natural wood itself is used as a furniture part, the unique pattern of natural wood appears as it is, and even if carved into various uneven patterns, the pattern remains as it is, and thus furniture parts with beautiful three-dimensional patterns could be manufactured. However, since the demand for furniture is soaring but the supply of wood is extremely limited, technology has been developed to produce furniture parts that can exhibit the unique patterns of natural wood, not processed wood but natural wood.
종래에 MDF 등의 가공목재에 피복하는 필름은 폴리에스테르계 수지 또는 폴리비닐계 수지로 된 필름에 인쇄층이 형성된 것으로, 가공목재의 표면에 직접 부착하는 형태로 피복되었는데, 이는 인쇄층과 수지층이 분리되지 않아 가공 목재의 표면에 엠보싱면이 있거나 굴곡면이 있는 경우에는 전사가 불가능한 문제가 있었다. 이러한 문제점을 극복하기 위하여 엠보싱면이나 굴곡면이 있는 가공목재에 무늬모양을 피복할 수 있는 곡면피복용 열전사필름이 개발된 바 있다 (대한민국 특허출원 제 93-6918호 참조). 그러나 이러한 곡면피복용 열전사 필름은 제조공정이 번거롭고 장시간이 소요되며, 실제로 가공 목재에 피복하였을 때 인쇄층이 쉽게 탈색되는 문제점이 있었다.Conventionally, a film coated on processed wood such as MDF is formed of a printing layer on a film made of polyester resin or polyvinyl resin, and is coated in a form of directly adhering to the surface of the processed wood, which is a printing layer and a resin layer. There was a problem that the transfer is impossible if there is an embossed surface or curved surface on the surface of the processed wood is not separated. In order to overcome this problem, a thermal coating film for curved coating has been developed that can cover the pattern of the embossed or curved surface of the wood (see Korean Patent Application No. 93-6918). However, such a thermal coating film for the curved coating has a problem that the manufacturing process is cumbersome and takes a long time, when the printed layer is easily discolored when actually coated on the processed wood.
이에 본 발명자는 상기와 같이 종래의 전사 필름이 가지는 문제점을 해결하기 위하여 노력하여 오던 중, ⅰ) 수지층, ⅱ) 셀룰로오스 니트레이트를 포함하는 이형층 및 ⅲ) 폴리아미드 수지 및 셀룰로오스 니트레이트를 포함하는 인쇄층으로 이루어지는 전사 필름이, 제조공정이 간단하고 전사후 인쇄층이 쉽게 탈색되지 않아 가공목재에 유용하게 적용될 수 있음을 알아내어 본 발명을 완성하였다.The present inventors have been trying to solve the problems of the conventional transfer film as described above, i) a resin layer, ii) a release layer containing cellulose nitrate and iii) a polyamide resin and cellulose nitrate. The transfer film consisting of a printed layer to complete the present invention was found that the manufacturing process is simple and the post-transfer printing layer is not easily discolored and can be usefully applied to the processed wood.
본 발명의 목적은 가공목재의 요철이나 측면에 효과적으로 무늬를 형성할 수 있을 뿐만 아니라 전사 후에 인쇄층이 쉽게 탈색되지 않는 가공목재 피복용 전사 필름 및 그의 제조방법을 제공하는 것이다.SUMMARY OF THE INVENTION An object of the present invention is to provide a transfer film for processing wood coatings and a method of manufacturing the same, which can effectively form a pattern on unevenness or side surface of the processed wood, and which does not easily discolor the printed layer after transfer.
상기 목적을 달성하기 위하여 본 발명에서는 ⅰ) 수지층, ⅱ) 셀룰로오스 니트레이트를 포함하는 이형층 및 ⅲ) 폴리아미드 수지 및 셀룰로오스 니트레이트를 포함하는 인쇄층으로 이루어지는 가공목재 피복용 전사 필름 및 그의 제조방법을 제공한다.In order to achieve the above object, in the present invention, the transfer film for processing wood coating comprising the resin layer, ii) a release layer containing cellulose nitrate, and iii) a printing layer containing polyamide resin and cellulose nitrate, and the production thereof Provide a method.

You can prevent it.
상기 전사 필름에서 가공목재는 중밀도 섬유판 (Medium Density Fiberboard ; MDF), 파티클 보드 (Particle Board; PB), 고압 멜라민 (High Pressure Melamine, HPM), 저압 멜라민 (Low Pressure Melamine, LPM) 중에서 선택된다.Processed wood in the transfer film is selected from Medium Density Fiberboard (MDF), Particle Board (PB), High Pressure Melamine (HPM), Low Pressure Melamine (LPM).
또한 본 발명에서는 상기 전사 필름의 제조방법을 제공한다.In addition, the present invention provides a method for producing the transfer film.
본 발명의 전사 필름은 수지층에 이형층을 바르는 단계 및 잉크로 무늬를 인쇄하는 공정으로 이루어지며, 이 때 인쇄는 그라비아 인쇄 방법으로 수행하는 것이 바람직하다. 이러한 제조방법은 종래의 전사 필름의 제조공정이 보호 프라이머 처리 공정과, 이를 24시간 정도 경화시키는 공정을 포함하는 것에 비하면 공정이 간단해 졌을 뿐만 아니라 시간도 단축된다.The transfer film of the present invention consists of a step of applying a release layer to the resin layer and a process of printing a pattern with ink, wherein printing is preferably performed by a gravure printing method. This manufacturing method is simpler as well as shorter in time than the conventional transfer film manufacturing process including a protective primer treatment step and a step of curing it for about 24 hours.
이하 본 발명을 실시예에 의하여 상세히 설명하기로 한다. 단 하기 실시예는 발명을 예시하는 것일 뿐 본 발명이 실시예에 의하여 한정되는 것은 아니다.Hereinafter, the present invention will be described in detail with reference to Examples.

<실험예>Experimental Example
본 발명의 실시예 1에서 제조된 전사 필름과 특허출원 제 93-6918호에 기재된 열전사 필름을 가공목재에 전사하여 비교하여 본 결과, 1주일 경과 후 특허출원 제 93-6918호에 기재된 열전사 필름은 육안으로 보기에도 탈색정도가 심하였으나 본 발명의 실시예 1에서 제조된 전사 필름은 전사후 인쇄층의 탈색이 전혀 일어나지 않았다. 이는 이형층으로서 셀룰로오스 니트레이트와 폴리우레탄 수지를 사용하고, 인쇄층에 폴리아미드 수지를 안료와 배합하여 사용한 것이 작용한 결과로 보여진다.The transfer film produced in Example 1 of the present invention and the thermal transfer film described in Patent Application No. 93-6918 were compared to the processed wood, and as a result, after one week, the thermal transfer described in Patent Application No. 93-6918 was obtained. Although the film was severely discolored even with the naked eye, the transfer film produced in Example 1 of the present invention did not cause any discoloration of the printing layer after the transfer. This is seen as a result of using cellulose nitrate and a polyurethane resin as a release layer and using a polyamide resin in combination with a pigment in the printing layer.
이상에서 살펴본 바와 같이, 본 발명의 전사 필름은 보호 프라이머층 처리 공정 및 경화공정 등이 불필요하여 제조공정이 간단할 뿐만 아니라 필름을 가공목재에 전사하였을 때 인쇄층이 가공목재로부터 쉽게 탈색되지 않아 가공목재에 유용하게 적용될 수 있다.As described above, the transfer film of the present invention does not require a protective primer layer treatment process and a curing process, so that the manufacturing process is simple, and when the film is transferred to the processed wood, the printed layer is not easily discolored from the processed wood, and thus processed. It can be usefully applied to wood.
