본 발명은 염료승화 인쇄용 건식 데칼필름에 관한 것으로서, 더욱 상세히는 염료승화 잉크수용지와 건식 데칼필름을 일체화한 염료승화 인쇄용 건식 데칼필름에 관한 것으로, 합성기재(1) 한쪽면에 매트형 실리콘 수지 배합물을 도포해서 구성되는 매트 이형층(2), 그 위에 승화염료 고착성, 인쇄 큐션성, 문지름 박리성, 필름 질김성이 우수한 잉크 정착층(3), 그 위에 고온의 인쇄 열헤드(TPH; Thermal Print Head)에 견디는 내열 윤활성, 인쇄 주행성, 승화염료 수용성, 자외선 차단성 및 전사필름 치수 안정성이 우수한 잉크 수용층(4)이 도포되어 구성되는 염료승화 인쇄용 건식 데칼필름을 최초로 제공하는데에 그 목적이 있다. The present invention relates to a dry decal film for dye-sublimation printing, and more particularly, to a dry decal film for dye-sublimation printing in which a dye-sublimation ink receptacle and a dry decal film are integrated, and a mat-type silicone resin on one side of a synthetic substrate (1).

건식 데칼(Dry Rub-off decal)기술은 종래 판박이라고 오래 동안 알려진 방식으로서 인쇄된 건식 데칼지를 피착제면에 올려 놓고 손이나 단단한 막대 등으로 문지르면 인쇄층이 떨어져 나와 전사되는 방식이다. 이러한 판박이는 주로 스크린 또는 옵셋방식으로 인쇄하여 대량 생산 하기 때문에 소량 다품종 전사물을 제작하기에는 제한적이다.Dry rub-off decal technology is a method known for a long time as conventional printing, and is a method in which a printed dry decal sheet is placed on an adherend surface and rubbed with a hand or a hard rod to separate the printed layer and transfer. Since this type of printing is mainly mass-produced by screen or offset printing, it is limited to produce small-volume transfers of various kinds.

습식 데칼(Waterslide decal)기술은 통상 물전사지라고 부르며 도자기, 유리 등 기물에 디지털 인쇄법이나 그라비아, 스크린 또는 옵셋방식 등 아날로그 방식으로 인쇄한 후, 물전사 공정을 거쳐 20마이크로미터 미만의 얇은 이미지 필름을 물에서 분리해 기물에 부착하고 소성(600도 이상의 고온에서 열처리)하거나, 저온 건조(150도 이내)하여 인쇄된 기물을 제작하는 것이다. 이 물전사가공 기술은 박막 이미지 필름을 젖은 상태로 전사하기에 거친 표면부터 매끄러운 소재 뿐만 아니라 양초같은 표면에도 부착할 수 있는 장점이 있지만, 반면 물에서 얇은 필름을 떼어내서 전사하고 건조시키는 공정이 다소 까다로워 작업자의 스킬에 따라 완성도가 크게 차이가 나는 단점이 있다. Waterslide decal technology, commonly called water transfer paper, is printed on objects such as ceramics and glass by analog methods such as digital printing, gravure, screen, or offset, and then goes through a water transfer process to produce a thin image film of less than 20 micrometers. is separated from water, attached to the object, fired (heat treatment at a high temperature of 600 degrees or more), or dried at a low temperature (within 150 degrees) to produce a printed object. This water transfer processing technology has the advantage of being able to attach to surfaces such as candles as well as rough and smooth materials because it transfers thin film image films in a wet state. It is difficult, and the degree of completion varies greatly depending on the skill of the worker.

이러한 습식방식의 물전사지가 갖는 문제점을 해결하고 사용자가 보다 용이하게 다룰 수 있는 건식방식의 전사지 또는 전사필름류 중에서 염료승화 인쇄에 호환되는 제품은 지금까지 알려진 바 없다. 대한민국 특허 제 10-1874598호에 건식방식으로 전사 가능한 스티커형 판박이가 공지되어 있으나, 이 기술은 일반적인 인쇄법(그라비아 또는 옵셋 등)에 적합한 기술이기 때문에, 200도 이상의 인쇄 열헤드(TPH)로 인쇄해야 하는 염료승화 인쇄방식에는 사용할 수 없는 단점이 있다.Among dry-type transfer papers or transfer films that solve the problems of these wet-type water transfer papers and can be handled more easily by users, no product compatible with dye-sublimation printing has been known so far. Korean Patent No. 10-1874598 discloses a sticker-type decal that can be transferred by a dry method, but since this technology is suitable for general printing methods (gravure or offset, etc.), printing with a printing heat head (TPH) of 200 degrees or more There is a disadvantage that it cannot be used in the dye-sublimation printing method that must be used.

본 발명은 건식방식의 우수한 전사성(Dry Rub-off transfer)을 갖고 동시에 염료승화 프린터에 탁월한 인쇄적성을 갖는 염료승화 인쇄용 건식 데칼필름을 제공하는 데 그 목적이 있다.An object of the present invention is to provide a dry decal film for dye-sublimation printing that has excellent dry rub-off transfer and at the same time has excellent printability in a dye-sublimation printer.

이를 위하여, 본 발명은 합성기재(1) 위에 실리콘계 수지와 매트제 안료로 배합된 코팅 조성물을 도포하여 매트 이형층(2)을 구성하고, 이 위에 도포되는 잉크 정착층(3)과 잉크 수용층(4)으로 순차적으로 도포하여 구성되어지는 염료승화 인쇄용 건식 데칼필름을 제공한다. 상기 데칼필름은 염료승화 프린터로 상기 잉크 수용층(4)에 인쇄하여 인쇄층(5)을 형성하고, 그 인쇄층(S)과 통상의 무기재 양면 점착필름을 합지하여 접착층(6)을 형성한 후, 그 접착층(6)면을 피착제(S) 위에 올려 놓고 손이나 단단한 물체로 강하게 문질러서(Dry Rubbing), 도막층(3+4+5+6)을 전사(Dry Rub-off transfer) 하는 방식으로 다양한 이미지 인쇄 용도에 사용된다.To this end, the present invention forms a mat release layer (2) by applying a coating composition formulated with a silicone-based resin and a mat pigment on a synthetic substrate (1), and an ink fixing layer (3) and an ink receiving layer ( 4) provides a dry decal film for dye-sublimation printing, which is composed of sequential application. The decal film is printed on the ink receiving layer 4 with a dye-sublimation printer to form a printed layer 5, and the printed layer (S) is laminated with a conventional inorganic double-sided adhesive film to form an adhesive layer 6 After that, the surface of the adhesive layer (6) is placed on the adherend (S) and strongly rubbed with a hand or a hard object (Dry Rubbing) to transfer the coating layer (3+4+5+6) (Dry Rub-off transfer) It is used for various image printing purposes in this way.

본 발명의 염료승화 인쇄용 건식 데칼필름은 고온의 인쇄 열헤드(TPH)로 인쇄하는 환경하에, 전술한 잉크 정착층(3)과 잉크 수용층(4)으로 구성된 코팅층(3+4)이 인쇄중에는 그 코팅층이 매트 이형층(2)에 잘 부착되어 들뜸(Delamination) 없이 안정적 도막을 유지하는 효과가 우수하다. In the dry decal film for dye-sublimation printing of the present invention, under a printing environment with a high-temperature printing thermal head (TPH), the coating layer 3+4 composed of the ink fixing layer 3 and the ink receiving layer 4 described above is formed during printing. The coating layer adheres well to the mat release layer 2, and the effect of maintaining a stable coating film without delamination is excellent.

더욱이, 본 발명은 잉크 수용층(3+4)에 인쇄된 인쇄층(5)을 무기재 양면 점착필름과 합지하여 접착층(6)을 형성해서, 피착제(S)에 접착시켜 단순히 물리적 문지름 과정을 통해 그 도막층(3+4+5+6)을 용이하게 피착제(S)에 전사하는 효과가 우수하다. Furthermore, in the present invention, the printing layer 5 printed on the ink receiving layer 3+4 is laminated with an inorganic double-sided adhesive film to form an adhesive layer 6, which is adhered to the adherend S, thereby eliminating a simple physical rubbing process. The effect of easily transferring the coating layer (3+4+5+6) to the adherend (S) is excellent.

도 1에 도시된 바와 같이, 본 발명의 데칼필름은. 합성기재(1) 한쪽면에 실리콘계 수지를 매트형 안료(실리카 등)와 배합하고 도포하여 구성되는 매트 이형층(2)의 표면에 폴리에스테르, 폴리우레탄, 폴리비닐부티랄, 폴리비닐아세탈, 염화비닐공중합체, 아크릴계 수지, 폴리스티렌 공중합체, 폴리카보네이트 등 고분자 바인더로 이루어지는 군에서 선택되는 단독 또는 2종 이상 수지로 조성된 잉크 정착층(3)과, As shown in Figure 1, the decal film of the present invention. Polyester, polyurethane, polyvinyl butyral, polyvinyl acetal, chlorinated An ink fixing layer (3) composed of one or two or more resins selected from the group consisting of polymeric binders such as vinyl copolymers, acrylic resins, polystyrene copolymers, and polycarbonates;

폴리우레탄, 셀롤로오스계 수지, 폴리비닐부티랄, 폴리아세탈, 폴리에스테르, 염화비닐공중합체, 아크릴계 수지, 폴리스티렌 공중합체, 폴리카보네이트 등 고분자 바인더로 이루어지는 군에서 선택되는 단독 또는 2종 이상으로 조성된 잉크 수용층(4)을 적층 도포하여 구성되어진다.Polyurethane, cellulose-based resin, polyvinyl butyral, polyacetal, polyester, vinyl chloride copolymer, acrylic resin, polystyrene copolymer, polycarbonate, etc. alone or composed of two or more selected from the group consisting of polymeric binders. It is constituted by layering and coating the ink-receiving layer 4 having been formed.

상기의 합성기재(1)는 염료승화 인쇄 매카니즘에 적합한 두께, 인쇄 쿠션성을 구현하기 위해, 백상지나 아트지, 합성지 또는 발포 PET나 올레핀 필름을 적절히 합지(Lamination) 처리하여 두께 120 ~ 300 마이크로미터 범위로 구성되어진다. 더욱 상세히, 두께가 120마이크로미터 이하이면 인쇄 열헤드(TPH)와의 밀착성이 나빠 염료층 색소가 충분히 승화되지 못해 이미지 발색도가 저하되는 단점이 있는 반면, 두께가 300마이크로미터 이상에서는 인쇄 열헤드와의 밀착이 너무 강해 잉크 수용층(4)과 블로킹 현상이 발생하거나 잉크 정착층(3)이 매트 이형층(2)으로 부터 분리되어 벗겨지는 문제점이 있다.In order to implement the thickness and printing cushioning properties suitable for the dye-sublimation printing mechanism, the synthetic substrate 1 is appropriately laminated with white paper, art paper, synthetic paper, foamed PET or olefin film to have a thickness in the range of 120 to 300 micrometers. is composed More specifically, if the thickness is less than 120 micrometers, the adhesiveness with the printing thermal head (TPH) is poor, and the color of the dye layer is not sufficiently sublimated, resulting in a decrease in color development of the image. There is a problem in that the adhesion between the ink receiving layer 4 and the ink receiving layer 4 is too strong, or the ink fixing layer 3 is separated from the mat release layer 2 and is peeled off.

상기 매트 이형층(2)은 그 위에 도포된 잉크 정착층(3)과 잉크 수용층(4)으로 구성되는 전사필름(3+4)이 염료승화 인쇄 도중에는 강하게 부착되었다가, 무기재 양면 점착필름을 합지하여 피착제에 전사할 시에는 용이하게 떨어지는 이형력를 유지해야 하고, 그 전사된 필름면은 은은하고 고급스러운 매트 특성을 표현하기 위해 실리콘 수지와 매트성 안료 등으로 도포하여 구성한다.In the mat release layer 2, the transfer film 3+4 composed of the ink fixing layer 3 and the ink receiving layer 4 applied thereon is strongly attached during dye-sublimation printing, and then the inorganic double-sided adhesive film is formed. When laminating and transferring to an adherend, it is necessary to maintain a release force that easily falls, and the transferred film surface is coated with silicone resin and matte pigment to express a soft and luxurious mat property.

상기 잉크 정착층(3)은 상기 매트 이형층(2)으로 부터 물리적 문지름 과정(Dry Rub-off transfer)에 의해 용이하게 분리되는 박리성, 염료승화 인쇄시 쿠션성, 잉크 수용층(4)을 통해 흡수되는 잉크를 보다 효과적으로 발색시키기 위해 코팅층 내부로 확산시키는 승화염료 고착성 및 필름 질김성을 제어하는 역할을 한다. 잉크 정착층(3)은 주 바인더로서 폴리에스테르, 폴리우레탄, 폴리비닐부티랄, 폴리비닐아세탈, 염화비닐공중합체, 아크릴계 수지, 폴리스티렌 공중합체, 폴리카보네이트 등 고분자 바인더로 이루어지는 군에서 선택되는 단독 또는 2종 이상으로 혼합하고, 큐션성이 우수한 천연 또는 합성왁스류, 탈크, 산화티타늄, 실리카, 알루미나 등 고체입자 첨가제를 단독 또는 2종 이상으로 혼합하고, 실리콘 가교제를 첨가하여 잉크 정착성(3) 조성물을 구성한다.The ink fixing layer 3 has peelability that is easily separated from the mat release layer 2 by dry rub-off transfer, cushioning during dye-sublimation printing, and absorption through the ink receiving layer 4. It plays a role in controlling the adhesion of the sublimation dye that diffuses into the coating layer and the film toughness in order to develop the color of the ink more effectively. The ink fixing layer 3 is a main binder selected from the group consisting of polymeric binders such as polyester, polyurethane, polyvinyl butyral, polyvinyl acetal, vinyl chloride copolymer, acrylic resin, polystyrene copolymer, and polycarbonate, or Ink fixation (3) make up the composition.

보다 상세히는 무게비로 주바인더 10-40%, 고체입자 첨가제 0.5 ~ 20%, 실리콘 가교제 0.1 ~ 2%, 톨루엔 20 ~ 40%, 메틸에틸케톤 20 ~ 40%, 에틸아세테이트 20 ~ 40%을 배합하고, 그 코팅액을 통상의 박막 코팅기술(마이크로 그라비아, 콤마, 나이프, 바코팅, 롤코팅 등)로 상기 매트 이형층(2) 위에 도포하고, 그 코팅두께는 1μm 내지 30μm, 더 바람직하게는 5μm 내지 20μm 범위로 한다. 만약 쿠팅두께가 5μm 이하이면 인쇄시 큐션성, 승화염료 고착성, 문지름 박리성, 필름 질김성이 크게 저하되고, 코팅두께가 20μm 이상이면 문지름 박리성과 전사필름의 뻣뻣성이 증가하여 전사 가공성이 떨어지는 단점이 있다.More specifically, 10-40% of the main binder, 0.5-20% of the solid particle additive, 0.1-2% of the silicone crosslinker, 20-40% of toluene, 20-40% of methyl ethyl ketone, and 20-40% of ethyl acetate are mixed in a weight ratio. , The coating liquid is applied on the mat release layer 2 by a conventional thin film coating technique (micro gravure, comma, knife, bar coating, roll coating, etc.), and the coating thickness is 1 μm to 30 μm, more preferably 5 μm to It is in the range of 20 μm. If the coating thickness is less than 5μm, the cushioning property, sublimation dye adhesion, rubbing releasability, and film toughness during printing are greatly reduced. there is.

한편, 고체입자 첨가제의 함량이 무게비로 0.5% 이하이면, 박리성이 감소되어 문지름 박리성이 저하되고, 그 함량이 무게비로 20% 이상되면, 문지름 박리성은 증가하는 반면 전사필름의 뻣뻣성이 증가하는 문제점이 있다. 실리콘 가교제 함량이 무게비로 0.1% 이하이면 전사필름의 치수 안정성이 저하되어 전사필름의 내구성이 떨어지며, 그 함량이 무게비로 2% 이상이면 매트 이형층(2)과의 결합력이 증가하여 잉크 정착성(3)의 문지름 박리성이 크게 저하되는 단점이 있다. 상기 방법 이외에도, 본 발명의 목적에 부합되는 잉크 정착층(3)의 물성을 발현한다면 공지의 어떠한 방법을 사용하여도 무방하다. On the other hand, when the content of the solid particle additive is less than 0.5% in weight ratio, the peelability is reduced and the rubbing peelability is lowered, and when the content is 20% or more in weight ratio, the rubbing peelability is increased while the stiffness of the transfer film is increased There is a problem with If the content of the silicone crosslinking agent is less than 0.1% by weight, the dimensional stability of the transfer film is lowered and the durability of the transfer film is deteriorated. There is a disadvantage in that the rubbing peelability of 3) is greatly reduced. In addition to the above method, any known method may be used as long as the physical properties of the ink fixing layer 3 meet the purpose of the present invention.

상기 잉크 수용층(4)은, 염료승화 인쇄가 정상적으로 진행되기 위한 탑코팅층으로서, 약 200도 이상 고온의 인쇄 열헤드(TPH)와 접촉시, 그 코팅층과 잉크리본간의 열융착 문제없이 원활한 인쇄주행이 되는 내열 윤활성이 우수해야 할 뿐만 아니라, 우수한 승화염료 수용성, 자외선 차단성, 전사필름 치수 안정성이 요구된다. 더욱이 잉크 수용층(4)에 형성된 인쇄층(5)의 염료가 시간 경과에 따라 서서히 탈색되는(역승화전사 현상) 단점이 최소화 되어야 하고, 그 인쇄층(5)에 합지되는 무기재양면 점착필름의 점착층(6)과의 탈리현상 없이 장기간 보존이 가능한 접착력이 잇어야 한다.. The ink receiving layer 4 is a top coating layer for dye-sublimation printing to proceed normally, and when it comes into contact with a printing thermal head (TPH) at a high temperature of about 200 degrees or more, smooth printing runs without thermal fusion between the coating layer and the ink ribbon. In addition to excellent heat-resistant lubricity, excellent sublimation dye water solubility, UV protection, and dimensional stability of the transfer film are required. Furthermore, the disadvantage that the dye of the printed layer 5 formed on the ink receiving layer 4 is gradually discolored over time (reverse sublimation transfer phenomenon) should be minimized, and the inorganic material double-sided adhesive film laminated to the printed layer 5 It must have adhesive strength that can be preserved for a long time without detachment from the adhesive layer (6).

본 발명의 잉크수용층(4)은 주 바인더로서 폴리우레탄, 셀롤로오스계 수지, 폴리비닐부티랄, 폴리아세탈, 폴리에스테르, 염화비닐공중합체, 아크릴계 수지, 폴리스티렌 공중합체, 폴리카보네이트 등의 열가소성 수지를 단독 또는 2종 이상으로 혼합하고, 큐션성과 내열 윤활성이 우수한 천연 또는 합성왁스류, 탈크, 산화티타늄, 실리카, 알루미나 등 고체입자 첨가제를 단독 또는 2종 이상으로 혼합하고, 자외선 안정제, 반응성 실리콘 수지, 그리고 폴리이소시아네이트 경화제를 혼합하여 잉크 수용층 조성물울 구성한다. 보다 상세히는, 무게비로 주 바인더 5 ~ 20%, 고체입자 첨가제 0.2 ~ 10%, 실리콘 수지 0.2 ~ 2%, 자외선 안정제 0.3 ~ 3%, 폴리이소시아네이트 경화제 0.1 ~ 1%, 톨루엔 15 ~ 35%, 메틸에틸케톤 30 ~ 45%, 에틸아세테이트 15 ~ 30%을 배합하고, 그 코팅액을 통상의 박막 코팅기술(마이크로그라비아, 콤마, 나이프, 바코팅, 롤코팅 등)로 상기 잉크 정착층(3) 위에 도포하고, 그 코팅두께는 1μm 내지 30μm, 더 바람직하게는 5μm 내지 20μm 범위로 한다. 만약 코팅두께가 5μm 이하이면 내열 윤활성이 저하되어 염료승화 인쇄시 잉크리본이 융착되어 인쇄 주행성이 나빠진다. 코팅두께가 20μm 이상이면 문지름 박리성과 전사필름의 뻣뻣성이 증가하여 전사 가공성이 떨어지는 문제점이 있다.The ink receiving layer 4 of the present invention is a thermoplastic resin such as polyurethane, cellulose-based resin, polyvinyl butyral, polyacetal, polyester, vinyl chloride copolymer, acrylic resin, polystyrene copolymer, polycarbonate, etc. as a main binder. alone or in combination of two or more, natural or synthetic waxes with excellent cushioning properties and heat-resistant lubricity, solid particle additives such as talc, titanium oxide, silica, and alumina, alone or in combination with two or more, UV stabilizers and reactive silicone resins. and a polyisocyanate curing agent to form an ink receiving layer composition. More specifically, 5 to 20% by weight of main binder, 0.2 to 10% of solid particle additive, 0.2 to 2% silicone resin, 0.3 to 3% UV stabilizer, 0.1 to 1% polyisocyanate curing agent, 15 to 35% toluene, methyl 30 to 45% of ethyl ketone and 15 to 30% of ethyl acetate are mixed, and the coating solution is applied on the ink fixing layer (3) by conventional thin film coating techniques (microgravure, comma, knife, bar coating, roll coating, etc.) And, the coating thickness is in the range of 1 μm to 30 μm, more preferably 5 μm to 20 μm. If the coating thickness is less than 5 μm, the heat-resistant lubricity is lowered, and the ink ribbon is fused during dye-sublimation printing, resulting in poor printing runability. If the coating thickness is 20 μm or more, there is a problem in that the transfer processability is deteriorated due to the increase in rubbing peelability and stiffness of the transfer film.

한편, 고체입자 첨가제 함량이 무게비로 0.2% 이하이면 내열윤활성이 저하되고, 그 함량이 무게비로 10%이상되면 표면이 거칠어져 표면평활도가 감소되어 인쇄발색도가 저하된다. 실리콘 수지의 함량이 무게비로 0.2% 이하이면, 내열 윤활성이 감소되어 염료승화 인쇄성이 떨어지는 반면 그 함량이 무게비로 2% 이상 되면 잉크 수용층의 표면 이형성이 증가되어 염료승화 인쇄시에 잉크리본이 미세하게 왜곡될 수 있는 문제점이 있다.On the other hand, if the content of the solid particle additive is less than 0.2% by weight, the heat resistance lubricity is lowered, and if the content is more than 10% by weight, the surface becomes rough and the surface smoothness is reduced, resulting in a decrease in printing color development. If the content of the silicone resin is less than 0.2% by weight, the heat resistance lubricity is reduced and the dye-sublimation printability is poor, whereas if the content is more than 2% by weight, the surface release property of the ink receiving layer is increased, resulting in fine ink ribbons during dye-sublimation printing. There are problems that can be distorted.
