Description

Illustration-coated gold leaf print and a manufacturing method thereof {Golden leaf printing coated with illustration and preparation method thereof}

The present invention relates to a gold leaf printed material prepared by secondary laminating a coated paper on which a primary laminating gold foil and an illustration are printed with a transparent film, and a method for manufacturing the same.

Gold has excellent decorativeness and preservation properties, and has been used a lot as a means of decoration or property preservation since the old days by molding it in the shape of a toad or tortoise. In addition, it is formed in the form of a square or round bar and is used as a means of saving and gifting.

In order to use high-priced pure gold in a small amount, the gold is melted and anointed, then put into a rolling mill to make gold foil. It is often used to manufacture and use very thin gold foil.

However, gold foil formed into a very thin thin film may be damaged by surrounding items or hands during storage or transport depending on the purpose of use, thereby reducing the quality of the final product or making it impossible to use. In addition, when foreign substances such as dust or moisture are attached or damaged in the process of transporting and storing the gold leaf, the use of the gold leaf is restricted and the reliability of the product is lowered.

In order to solve the problem of the thin gold leaf being damaged, the method of coating the coating vinyl on the surface of the gold leaf has a problem in that the gold leaf is contracted and deformed by heat generated during the coating process. In the Republic of Korea Patent No. KR10-0333054 (disappeared on Aug. 19, 19), in order to solve the deformation of the gold leaf by heat during the coating process, the gold foil paper with a release paper attached to it is coated with a vinyl coating and is damaged or damaged. Disclosed is a method of producing a finished product by coating one side of the gold foil paper by separating the release paper from the gold foil paper after coating to maintain the formability without damage, and printing and coating a design or character on the uncoated back surface.

In addition, gold leaf can be image printed using offset printing or silk screen printing method for the aesthetic feeling of decoration, but in the offset printing method, gold leaf with high ductility and malleability is pressed and spread out on a rubber blanket. There is a problem that it is difficult to expect good prints because of the loss of color, and there is a problem that it is difficult to properly print color photos, etc. because the silk screen printing method has a limit in creating a small size of the silk screen hole. There is a problem with this falling.

On the other hand, laminating is a technique of coating a film on the surface of an ID card or various printed materials to make it shiny and prolong its life. ) laminating and cold type laminating, and can be divided into glossy laminating and matte laminating depending on whether it is glossy or not. Dry laminating is a method of fusion bonding of vinyl with almost heat while using a little water-based or oil-based chemical, but it is not widely used at present because of the disadvantage of generating bubbles. Wet laminating is a method of attaching vinyl using an adhesive, and it does not generate bubbles and has good quality. Currently, wet laminating is generally used. Korean Patent Laid-Open Publication No. KR 10-2001-0070741 (published on July 27th) discloses a method of depositing a gold plate on a base film and then adhering a protective film in a laminating method as a method for manufacturing a card having a gold plate, but the above method There is a problem in that the gold plate is cracked in the process of pressing for silver laminating adhesion.

Accordingly, the present inventors have researched a method for manufacturing a gold leaf printed matter coated with a desired illustration, and as a result, the primary laminated gold leaf and the coated paper on which the illustration is printed are laminated secondary to preserve the luster without damaging the gold leaf, and It was confirmed that gold leaf prints can be produced that can enter, and that scratches on the surface are prevented, so that the illustrations are maintained for a long time without damage and easy to store.
