본 발명은 유리접합 등에 사용되는 PVB(Polyvinyl Butyral) 등의 접합필름에 <1> 인쇄하기 위한 잉크조성물에 관한것으로서, 상세하게는 인쇄시 접합필름이 부풀어 오르지 않아 인쇄장치의 잉크젯 헤드에 걸림현상이 발생하지 않는 등 인쇄성이 우수하고, 유리접합 시 유리와의 점착성 및 발색도가 우수한 접합필름인쇄용 잉크조성물에 관한 것이다.The present invention relates to an ink composition for printing on a bonding film such as PVB (Polyvinyl Butyral) used for glass bonding, etc., in detail, the bonding film does not swell during printing, so that the inkjet head of the printing device is jammed. It relates to an ink composition for printing a laminated film that has excellent printability, such as no generation, and excellent adhesion with glass and color development when bonding glass.
최근에 방범용, 인테리어용 등의 많은 용도로 접합유리가 사용되고 있다. 접합유리는 두장의 유리사이에 PVB(Polyvinyl Butyral) 등의 접합필름을 게재시킨 후 진공상태에서 고온처리하여 제조된다.Recently, laminated glass has been used for many purposes such as crime prevention and interior use. Laminated glass is manufactured by placing a laminated film such as PVB (Polyvinyl Butyral) between two sheets of glass and then processing it at a high temperature in a vacuum.
종래의 잉크조성물을 PVB 등의 접합필름에 분사하여 인쇄하는 경우 PVB 등의 접합필름이 부풀어 오르고, 이에 따라 접합필름이 인쇄장치의 잉크젯 헤드에 걸려 인쇄가 원활히 이루어지지 않는 문제가 있다.In the case of printing by spraying the conventional ink composition onto a bonding film such as PVB, the bonding film such as PVB swells, and accordingly, the bonding film is caught by the inkjet head of the printing apparatus, and there is a problem in that printing is not performed smoothly.
이러한 문제 때문에 인쇄시 부풀어 오르는 현상이 발생하지 않는 PVC필름, 종이 또는 천 등에 다양한 무늬로 인쇄한 후 두장의 유리사이에 게재되는 두장의 접합필름 사이에 게재시켜 접합유리를 제조하고 있는 실정이다. 이러한 접합유리 제조방법의 경우 고가의 접합필름이 접합유리 1장당 2장이 소요되고, 별도의 PVC필름 및 종이가 소요됨에 따라 제조공정이 번거롭고 생산비용이 상승하는 문제가 있다.Due to this problem, laminated glass is manufactured by printing various patterns on PVC film, paper or cloth, etc., which does not cause swelling during printing, and then placing it between two sheets of laminated film placed between two sheets of glass. In the case of such a laminated glass manufacturing method, two expensive laminated films are required per sheet of laminated glass, and as a separate PVC film and paper are required, the manufacturing process is cumbersome and the production cost is increased.
이와 같은 문제점을 해결하기 위한 본 발명은 인쇄시 접합필름이 부풀어 오르지 않아 인쇄장치의 잉크젯 헤드에 걸림현상이 발생하지 않는 등 인쇄성이 우수하고, 유리접합시 유리와의 점착성 및 발색도가 우수한 접합필름인쇄용 잉크조성물을 제공함에 그 목적이 있다.The present invention for solving such problems is excellent in printability, such as the bonding film does not swell during printing, so that the inkjet head of the printing apparatus does not jam, and adhesion with glass and color development are excellent during glass bonding. An object of the present invention is to provide an ink composition for film printing.
