Typically, there are wallpapers with various patterns in the case of wall decoration. Something is known. On the other hand, it is known that such a decorative sheet has a glitter layer so that the decorative pattern on the surface can show a glittering effect that reflects light. Such a glitter layer is formed by applying glitter powder particles to the film base layer, and the pattern printed on the film base layer can obtain an enhanced decorative effect due to the glitter effect of the glitter powder particles, but the pattern printed on the film base layer is glittery. There is a drawback that it is not clearly expressed to the outside because it is covered by powder particles. In the case of decorative sheets using glitter, most of them have a problem in that the effect of the decorative pattern to be expressed is lowered, although the glitter effect can be expected.

도 1a는 본 발명의 제1 실시예에 따른 장식시트의 구성을 예시적인 단면도로 보인 것이다. 도 1a에서 보인 제1 실시예의 장식시트는 예를 들어 벽지 또는 어떠한 장식대상물의 표면을 장식하는 장식지로 사용될 수 있는 것이다. 이와 같은 본 발명의 제1 실시예에 따른 장식시트는 장식시트의 성층구조를 유지할 수 있도록 하는 시트지지기재로써 투명의 PET(폴리에틸렌 테레프탈레이트) 필름(10)이 제공된다. 통상적으로 이러한 PET 필름(10)은 투명의 필름이고 두께는 100~75㎛ 정도이다. 이와 같은 시트지지기재인 PET 필름(10)에는 이후 상세히 설명되는 바와 같이 실질적인 장식시트의 시트기재인 폴리우레탄층(12)과 글리터층(14)이 차례로 도층된다.Figure 1a is an exemplary cross-sectional view of the configuration of a decorative sheet according to a first embodiment of the present invention. The decorative sheet of the first embodiment shown in FIG. 1A can be used as wallpaper or decorative paper for decorating the surface of any decorative object, for example. In the decorative sheet according to the first embodiment of the present invention, a transparent PET (polyethylene terephthalate) film 10 is provided as a sheet supporting base material to maintain the layered structure of the decorative sheet. Typically, such a PET film 10 is a transparent film and has a thickness of about 100 to 75 μm. As will be described later in detail, the polyurethane layer 12 and the glitter layer 14, which are the sheet substrates of the actual decorative sheet, are sequentially coated on the PET film 10, which is a sheet support base material.

이들 폴리우레탄층(12)과 글리터층(14)이 도층되기 전에 PET 필름(10)에 이형층(16)이 도층되고 이어서 점착층(18)이 도층된다. 잘 알려진 바와 같이, 이형층(16)은 폴리우레탄층(12)과 글리터층(14)으로 구성되는 시트기재가 실질적으로 사용될 때 PET 필름(10)으로부터 용이하게 분리될 수 있도록 하기 위한 것이고, 점착층(18)은 장식시트의 시트기재가 벽면 또는 장식표면에 점착될 수 있도록 하기 위한 것이다. 이들 이형층(16)과 점착층(18)은 일반적인 시트지에서 널리 알려져 있는 것이므로 이들의 성분이나 조성에 대하여서는 상세한 설명을 하지 않기로 한다.Before the polyurethane layer 12 and the glitter layer 14 are coated, the release layer 16 is coated on the PET film 10, followed by the adhesive layer 18. As is well known, the release layer 16 is intended to be easily separated from the PET film 10 when the sheet base material composed of the polyurethane layer 12 and the glitter layer 14 is actually used, and the adhesive The layer 18 is for allowing the sheet base of the decorative sheet to be adhered to a wall surface or a decorative surface. Since these release layer 16 and adhesive layer 18 are widely known in general sheet paper, their components or compositions will not be described in detail.

장식시트의 시트기재를 구성하는 폴리우레탄층(12)은 투명하며 광택성을 갖는 폴리우레탄층으로써 폴리우레탄(PU)에 용제인 DMF(디메틸포름아미드), MEK(메틸에틸케톤)과 TO(톨루엔)을 혼합한 것이다.The polyurethane layer 12 constituting the sheet base of the decorative sheet is a polyurethane layer that is transparent and has luster. The polyurethane (PU) contains solvents such as DMF (dimethylformamide), MEK (methyl ethyl ketone) and TO (toluene). ) is mixed.

폴리우레탄층(12)에 도층되는 글리터층(14)은 반짝이 효과를 보이면서 실질적으로 장식문양이 표현될 수 있는 장식층을 구성한다.The glitter layer 14 coated on the polyurethane layer 12 constitutes a decorative layer capable of substantially expressing a decorative pattern while showing a glittering effect.

반짝이 효과를 보이는 장식층을 구성하는 글리터층(14)은 주성분으로 폴리우레탄과 글리터분말입자의 혼합물로 구성되며, 특히 글리터분말입자는 장식문양의 승화인쇄를 위한 승화전사과정에서 승화잉크의 착색이 이루어질 수 있도록 제조된다. 이를 위하여, 글리터분말입자는 먼저 출발물질로서 18~25㎛ 두께의 알루미늄증착 PET 필름이 사용되고, 열경화성 수지인 DAP(디아릴프탈레이트수지, diallyl phthalate prepolymer; 상품명 DAISO DAP)와 초화면(硝化綿, 니트로셀룰로오스)의 맑고 투명한 혼합물을 상기 알루미늄증착 PET 필름의 양면에 코팅한다. 이와 같이 DAP와 초화면의 혼합물이 양면에 코팅된 알루미늄증착 PET 필름을 미분쇄하여 글리터분밀입자를 얻는다. 폴리우레탄에 이러한 글리터분말입자를 혼합한 글리터층(14)이 폴리우레탄층(12)상에 도층된다.The glitter layer 14 constituting the decorative layer showing the glitter effect is composed of a mixture of polyurethane and glitter powder particles as main components. manufactured to make it possible. To this end, the glitter powder particles first use an aluminum-coated PET film with a thickness of 18 to 25 μm as a starting material, and a thermosetting resin, DAP (diaryl phthalate resin, diallyl phthalate prepolymer; trade name: DAISO DAP) and nitro cellulose) is coated on both sides of the aluminized PET film. In this way, the mixture of DAP and superimposed cotton is pulverized to obtain glitter powder particles by pulverizing the aluminum-coated PET film coated on both sides. A glitter layer 14 in which these glitter powder particles are mixed with polyurethane is coated on the polyurethane layer 12.

이와 같은 글리터층(14)을 구성하는 글리터분말입자는 열경화성 수지인 DAP가 코팅되어 있어 이에 장식문양의 승화인쇄를 위한 승화전사과정에서 승화잉크의 착색이 용이하게 이루어져 인쇄층을 구성하며 이는 다양한 장식문양의 구현이 가능하도록 한다. 이러한 승화전사 인쇄층의 이해를 돕기 위하여 도면에서는 인쇄층(20)으로 도시하여 표현하였다.The glitter powder particles constituting the glitter layer 14 are coated with DAP, which is a thermosetting resin, so that the coloring of the sublimation ink is easily performed in the process of sublimation transfer for sublimation printing of decorative patterns to form a printing layer, which constitutes a printing layer. It enables the implementation of the pattern. In order to help the understanding of the sublimation transfer printing layer, it is shown and expressed as a printing layer 20 in the drawings.
