Description

Makeup sheet {DECORATIVE SHEET}

The present invention relates to a makeup sheet.

Conventionally, the cosmetic sheet which laminated | stacked the pattern-shaped layer, the transparent resin layer, and the transparent surface protection layer on the base material sheet is known. For example, in Patent Document 1, a transparent surface protective layer containing a patterned layer, a transparent adhesive layer, a transparent polypropylene resin layer, and an ionizing radiation curable resin is sequentially formed on a base sheet containing a polyolefin resin. The makeup sheet which consists of this is disclosed. The base sheet and the transparent resin layer are both made of synthetic resin, and this makeup sheet is referred to as a so-called doubling specification (see FIG. 2). In the doubling specification, when the total thickness of the base sheet and the transparent resin layer is 100 µm or more, bending processing is easy.

However, the above decorative sheet of the doubling specification has a problem that the transparent resin layer is whitened and the designability tends to decrease when the sheet is bent. In addition, since there is a transparent resin layer on the patterned layer, when the haze (cloudiness, etc.) are present in the transparent resin layer, the vividness of the pattern is likely to be lowered. In addition, since a patterned layer is interposed between the base sheet and the transparent resin layer, the adhesive force tends to decrease over time between the base sheet and the transparent resin layer. Moreover, since it is necessary to perform a weathering process to a transparency resin layer, a production cost tends to become high.

On the other hand, the makeup sheet (so-called single layer specification) which set the thickness of a base material sheet (synthetic resin layer) to 100 micrometers or more without providing a transparent resin layer is proposed (refer FIG. 3). In this single layer specification, since the thickness of a synthetic resin layer is large, bending process is easy. In addition, by making a base material sheet into a colored layer, whitening at the time of bending does not become a problem. However, there is a problem that the production cost tends to be high in that a base sheet having a large thickness is prepared.

 As an improvement of a doubling specification, the makeup sheet (so-called back print specification) which set the thickness of the transparent resin layer to 100 micrometers or more without providing a base material sheet is also proposed (refer FIG. 4). In this back-printing specification, it is not necessary to prepare a base sheet, but the production cost tends to be high in that a transparent resin layer of a large thickness or a transparent resin layer require weather treatment, and the haze is present in the transparent resin layer. In this case, there is also a problem in that the vividness of the pattern shape tends to be lowered.

Therefore, the development of the cosmetic sheet which improved the fault of these conventional products is desired.
