Description
본 발명은 폴리에스텔 필름에 문자, 도형등을 인쇄하는 방법에 관한 것으로서, 더 상세히 설명하면 경질의 폴리에스텔 필름에 전사지에 인쇄된 문자, 도형등을 열염착 전사하는 방법에 관한 것이다.The present invention relates to a method of printing a character, a figure, and the like on a polyester film, and more particularly, to a method of thermally dye-transferring a character, a figure, etc. printed on a transfer paper on a rigid polyester film.
종래에도 전사지에 인쇄된 도형을 합성수지에 전사하는 방법이 알려졌다. 예를 들면 전사지에 임의의 도형이나 문자를 인쇄하고 합성수지에 인쇄면을 대접시킨다음 가열 압착하므로서 전사지의 인쇄층이 합성수지표면에 전사되도록하는 방법이 알려졌으나 이와같은 종래의 방법은 합성수지 표면에 전사된 인쇄층이 돌출형성되므로 인쇄층이 쉽게 마손되어 일정 기간 사용하면 상품가치가 저하되는 문제점을 나타내었다. 그리고 이와 같은 종래 방법의 결점을 개선하기 위하여 승화성 염료를 사용하여 전사지에 인쇄한 다음 이를 합성수지 표면에 대접시키고 200℃이상의 고열로 가열 압착하므로서 전사지의 인쇄층이 합성수지에 침투되도록 하는 방법이 개발되었다.Conventionally, a method of transferring a figure printed on a transfer sheet to a synthetic resin is known. For example, it has been known to print an arbitrary figure or character on a transfer paper, treat the printed surface on a synthetic resin, and then heat-press the transfer layer so that the print layer of the transfer paper is transferred to the synthetic resin surface. Since the printed layer is formed to protrude, the printed layer is easily worn out and shows a problem that the product value is lowered when used for a certain period of time. In order to improve the drawbacks of the conventional method, a method was developed in which a printing layer of a transfer paper was penetrated into a synthetic resin by printing on a transfer paper using a sublimable dye and then treating the transfer paper on a synthetic resin surface and heat-compressing at a high temperature of 200 ° C. or higher. .
그러나 이 방법은 판상의 아크릴 수지에만 적용되었는바, 이 경우 가열온도가 200℃ 이상되어야하므로 피인쇄물이 필름인 경우에는 가열에 의하여 피인쇄물이 찌그러지는 문제가 나타나고 아크릴 판에만 사용 가능한 방법으로 알려져 있어서 다른 종류의 합성수지에는 사용할 수 없는 것으로 생각되어왔다.However, this method was applied only to the plate-shaped acrylic resin. In this case, since the heating temperature should be 200 ° C. or higher, when the to-be-printed film is a film, the problem of distortion of the to-be-printed material due to heating appears and it is known as a method that can be used only for the acrylic plate. It has been thought that it cannot be used for other types of synthetic resins.
본 발명자는 기념패나 상패의 도안판등으로 사용할 투명한 폴리에스텔 필름에 필요한 문자나 도형을 전사하기 위하여 시도하여 본 결과 통상의 합성수지에 대한 전사방법은 인쇄된 문자나 도형의 마손이 심하여 상품가치가 저하되므로 이용할 수 없고 아크릴 수지판에 전사하는 방법을 그대로 시도하여 본 바에 의하면 200℃ 이상의 고열로 가열 압착할때 필름이 늘어나면서 찌그러져 요구하는 도형을 얻을 수 없고 수축시에는 찌그러져 상품으로서의 가치가 없게 되므로 전술한 공지 전사 방법들이 폴리에스텔 필름에는 이용할수 없음을 알게 되었다.The present inventor attempts to transfer characters or figures required for a transparent polyester film to be used as a commemorative plaque or a plaque of a plaque, and as a result, a transfer method for a conventional synthetic resin has a severe deterioration of printed characters or figures, resulting in a decrease in product value. Since it was not possible to use it and tried to transfer it to the acrylic resin plate as it is, when the film is stretched and heated at a high temperature of 200 ° C. or higher, the film is crushed, and the required shape cannot be obtained. It has been found that one known transfer method is not available for polyester films.
특히 폴리에스텔 필름은 폴리에스텔 수지가 갖고 있는 높은 결정성과 분자 배열의 치밀성으로 인하여 염착이 잘 되지 않으므로 다른 수지에 비하여 전사방법에 의한 인쇄가 곤란하게되는 문제점이 있다.In particular, the polyester film is difficult to dye due to the high crystallinity of the polyester resin and the compactness of the molecular arrangement, which makes printing by the transfer method difficult compared to other resins.
본 발명은 폴리에스텔 필름이 120-150℃정도에서는 열변형되지 않으므로 이러한 온도범위에서 전사시키되 전사하기전에 폴리에스텔필름을 전처리하여 치밀한 조직을 이완시키고 염료의 침투를 용이하게 하므로서 폴리에스텔 계승화 성염료로 인쇄된 전사지를 사용하여 전사하는 경우 염료가 폴리에스텔필름의 조직내에 침투되어 염착 효과가 향상되고 그결과 전사된 인쇄층이 마손되거나 벗격지는 일이 없게된다는 사실을 알게되어 본 발명을 완성하게 된 것이다.In the present invention, the polyester film is not thermally deformed at about 120-150 ° C., so it is transferred in such a temperature range, but before the transfer, the polyester film is pretreated to relax the dense tissue and facilitate the penetration of the dye, thereby facilitating the penetration of the dye. When the transfer paper printed using the transfer paper is transferred, the dye penetrates into the tissue of the polyester film, so that the dyeing effect is improved, and as a result, the transferred print layer is not worn or peeled off, thereby completing the present invention. It is.
본 발명의 방법에 의하면 전사지에 인쇄하는 염료는 폴리에스텔계 승화성 분산염료를 사용한다. 특히 본 발명에 적당한 염료로는 120-150℃에서 승화하는 시바셋(CIBACET : 스위스국 시바리미티드의 상품명) 분산염료가 적당하며 전사지는 통상적인 방법에 의하여 모조지등에 인쇄하여 사용한다.According to the method of the present invention, a dye for printing on a transfer sheet uses a polyester-based sublimable disperse dye. Particularly suitable dyes suitable for the present invention are CIBACET (dyed by CIBACET, a Swiss brand of Sivari Limited) disperse dye at 120-150 ° C., and the transfer paper is printed on imitation paper and the like by a conventional method.
폴리에스텔 필름은 전사지로 전사하기전에 o-페놀 페닐을 메타놀, 에타놀같은 알콜 또는 수산화나트륨 용액에 용해시킨 용액에 침지하거나 또는 필름의 전사면에 전술한 용액을 도포시켜 사용한다.The polyester film is used by immersing in a solution in which o-phenol phenyl is dissolved in alcohol or sodium hydroxide solution such as methanol, ethanol or the like as described above on the transfer surface of the film before transferring to the transfer paper.
폴리에스텔 필름을 o-페닐페놀용액으로 처리하는 것은 필름의 조직을 이완시키고 팽운시켜 염료의 침투를 용이하게 한다.Treatment of the polyester film with o-phenylphenol solution relaxes and swells the structure of the film to facilitate penetration of the dye.
이하 본 발명의 방법을 설명하면 다음과 같다.Hereinafter, the method of the present invention will be described.
o-페닐 페놀을 메타놀, 에타놀 같은 알콜에 용해시켜 2-5% 용액으로 만들고 이용액을 폴리에스텔 필름의 전사할 표면에 도포하거나 또는 이용액에 필름을 침지하였다가 꺼내어 건조시킨다. 건조직후 필름의 인쇄할 표면에 시바셋 분산염료로 인쇄된 전사지의 인쇄면을 대접시키고 120-150℃에서 20초내지 1분간 가열압착하고 전사지를 제거한다.Dissolve o-phenyl phenol in alcohols such as methanol and ethanol to make a 2-5% solution and apply the solution to the surface to be transferred to the polyester film or dip the film in the solution and take it out to dry. Immediately after drying, the printing surface of the transfer paper printed with Shivaset dispersion dye on the surface to be printed on the film is treated and heated and pressed at 120-150 ° C. for 20 seconds to 1 minute, and the transfer paper is removed.
이와 같은 본 발명의 방법에 의하면 o-페닐페놀에 의하여 표면 조직이 이완된 폴리에스텔 필름의 조직내에 염료가 승화 침투되게 되고 사용하는 염료가 폴리에스텔계 분산염료이므로 침투된후 필름 조직내에 일체화 되게되어 필름 표면이 마모되거나 세제등으로 세척하는 경우에도 인쇄층이 벗겨지는 일이 없게 된다.According to the method of the present invention, the dye is sublimed into the tissue of the polyester film whose surface structure is relaxed by o-phenylphenol, and the dye used is integrated into the film structure after being penetrated because it is a polyester-based dispersion dye. Even if the surface of the film is worn out or washed with detergent, the printed layer is not peeled off.
본 발명에 의하여 제조되는 폴리에스텔 필름은 기념패나 상패용 도안판, 책 카바, 장식용 투명 필름등 각종 용도에 사용할 수 있다.The polyester film manufactured by this invention can be used for various uses, such as a memorial plaque, a pattern plate for plaques, a book cover, and a decorative transparent film.
[실시예]EXAMPLE
o-페닐페놀 5g을 500ml의 에타놀에 용해시킨다음 물로 희석하여 0.5%의 o-페닐페놀용액을 만들고 이 용액 속에 폴리에스텔 필름을 침지하였다가 꺼내어 자연 건조시킨다. 필름의 인쇄할 표면에 폴리에스텔계시바셋 분산 염료로된 인쇄 잉크로 인쇄된 전사지의 인쇄면을 대접시키고 두평판사이에 필름과 전사지를 넣어 150℃로 가열 하면서 1분간 압착한 다음 상면판과 전사지를 제거하고 전사된 폴리에스텔 필름을 얻는다.5 g of o-phenylphenol is dissolved in 500 ml of ethanol and diluted with water to make a 0.5% o-phenylphenol solution. The polyester film is immersed in this solution, and then dried. The printing surface of the transfer paper printed with the printing ink of polyester-based shivaset disperse dye is welded on the surface of the film, and the film and the transfer paper are put between the two flat plates and pressed at a temperature of 150 ° C. for 1 minute, then the top plate and the transfer paper are pressed. It is removed and a transferred polyester film is obtained.
