2. Description of the Related Art As a decorative material used as a surface material such as furniture, furniture, doors, shelves and the like, and a wood opening material, a vinyl chloride resin-based decorative material and a diallyl phthalate resin-based decorative material are generally used. Vinyl chloride resin-based cosmetics
It is most used as a decorative material with a high degree of freedom in coloring, embossing, printing suitability, etc.

[0003]

However, since the above-mentioned vinyl chloride resin-based decorative material generates hydrogen chloride gas during combustion, the incineration treatment at the time of disposal cannot be performed in a general incineration plant. Goods were desired.

A decorative sheet using an ABS resin instead of a vinyl chloride resin has been developed, but the phenomenon of whitening at the time of bending is large. For example, in the processing of V-cut, wrapping, soft foam, etc., the appearance due to bending whitening deteriorates. However, there is a problem that the commercial value is impaired. This bending whitening is due to the properties of the ABS resin, and it has been extremely difficult to improve the composition.

In order to solve the above-mentioned problems, the present invention provides a decorative sheet using an ABS resin by providing solid printing for concealing bending whitening, so that it can be applied to processing such as V-cut, wrapping, and soft foam. An object of the present invention is to provide an ABS resin-based decorative sheet that does not show a whitening phenomenon on its surface and that can be easily incinerated during disposal.

The ABS resin-based decorative sheet 21 of the present invention comprises a plurality of ABS resin-based films as base materials and, for example, heat lamination or bonding of two base materials 2A and 2B via a bonding resin binder. Can be joined by high-temperature heat lamination without the use of a resin binder. A solid printing layer 3a of a printing ink containing a titanium oxide pigment is provided on the surface side of the one base material 2A to be the upper layer.
A colored printed layer 3b on the solid printed layer 3a, a transparent protective layer 4 formed on the colored printed layer 3b, and an embossed pattern 4a formed on the transparent protective layer. I have.

The ABS resin film used as the base material may be a mixture of ordinary ABS resin alone or other compatible resins (eg, MBS resin, polycarbonate resin, styrene resin, etc.). For applications requiring heat resistance, for example, in the case of a decorative sheet for wood opening, a heat-resistant ABS resin containing 70 to 95 parts by weight of a normal ABS resin and α-methylstyrene and / or heat-resistant A
A resin composition comprising 5 to 30 parts by weight of the S resin can be used, and deformation due to heat at the time of bonding with a hot melt adhesive can be prevented. These ABS resin films have a thickness of 50 by calendering or extrusion molding.
