Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial field of application> The present invention relates to a decorative sheet having an embossed surface with excellent design.

<Prior Art> Conventionally, as a decorative sheet of this type, there is a decorative sheet in which a film having a metallic luster is embossed and then a transparent film is attached to the embossed surface by a dry lamination method.

<Problems to be Solved by the Invention> In the case of a decorative sheet having an embossing inside, since a flat upper film and an uneven base film are attached by dry lamination, the unevenness is better than the thickness of the adhesive used for dry lamination. When the depth is deep, the surface is affected by the unevenness or air is mixed in, so that the deep unevenness cannot be formed and only a hairline of about 30 μ or less can be expressed.

<Means for Solving the Problems> The present invention was conceived in order to solve the above-mentioned problems of the prior art. A sol-like synthetic resin of the same quality as the synthetic resin is formed on the embossed surface of the embossed synthetic resin film. A decorative sheet having an embossed surface in which a pattern is printed on one side and a synthetic resin film having an emboss on the other side is stuck with the printed side inside, which is coated so as to fill the recesses of the emboss.

Detailed description will be given below with reference to the drawings. The embossed synthetic resin film (1) is embossed as shown in FIG.
On the (2) surface, a sol-like synthetic resin of the same quality as the synthetic resin film (1)
A decorative sheet made by coating (3) on one side with a synthetic resin film (5) with the pattern (4) printed on one side and sticking the printed side of the pattern (4) inside and at the same time embossing the surface. is there.

Next, the production method will be described. On the embossed vinyl chloride sheet with 8 parts by weight of plasticizer, 0.15 m / m, and pearl kneaded with pearl, a vinyl chloride resin in a sol state is embedded with the emboss (2), and A pattern is printed on one side of what is coated to the extent that a sol layer is formed (thickness: about 50 μ, coating temperature: 140 ° C.), for example, 8 parts by weight of a plasticizer,
A 0.1 m / m clear vinyl chloride sheet is attached so that the printing surface faces inward, and at the same time as this attachment, embossing is performed to form. The embossing may be provided on the clear vinyl chloride sheet in advance. The laminating method may be a usual method such as heat laminating or dry laminating with an adhesive.

Next, the melting temperature of the sol coat of the vinyl chloride resin is preferably low so as to prevent the embossing (2) from returning due to the heat, and the sol coat is preferably thin.

The plasticizer content of the synthetic resin sheet (1) is preferably 0 to 20% by weight, and emboss formation is possible even without plasticization, but the smaller the plasticizer, the smaller the emboss return and the heating temperature during embossing. If you sol coat at a lower temperature,
The emboss does not return.

Further, the synthetic resin film (5) is not so much influenced by the plasticizer, and may be within the range usually used.

<Operation> Since the present invention has the above-described configuration, the embossing is provided on the surface and the inside of the sheet respectively, and the reflection position of light is different, so that the pattern has a wood grain pattern, the natural wood has The texture and texture are similar to the texture.

<Examples> Examples are shown below.

Material Synthetic resin film (1) Plasticizer amount 8 parts by weight, pearl kneaded with a thickness of 0.15 m / m Vinyl chloride sheet with a depth of 40 to 50 µ embossed Sol coat layer Vinyl chloride resin at a temperature of 140 Coated with the above embossed surface at a temperature of 50 ° C. Synthetic resin film (5) A plasticizer amount of 8 parts by weight and a thickness of 0.1 m / m of a clear vinyl chloride sheet with a wood grain pattern printed on one side, Embossed with a depth of 40 to 50μ on the other surface A sol coat layer is applied to the embossed surface of the above synthetic resin film (1), and the synthetic resin film (5) is attached with the printed surface inside. .

Next, regarding the relationship between the melting temperature of vinyl chloride sol and the layer thickness,
Examining the return of embossing (2), the results are shown in the table below.

From the above table, the lower the temperature and the thinner the sol layer, the smaller the emboss return, and the good quality decorative sheet is obtained. be able to.

<Effect of device> Since the device of the present invention is configured as described above, there are two types of embossing on the surface and inside of the decorative sheet, so the reflection position of light from the outside is different. The texture can be close to natural.
