Abstract

PROBLEM TO BE SOLVED: To eliminate generation of noxious gas such as chlorine gas at incinerating for disposal, completely degrade with microorganism in the soil at the time of disposal by burying in the ground so as to change into soil and stabilize the ground, by sequentially laminating a biodegradable resin layer and a picture pattern layer on one face of a base material. SOLUTION: A first biodegradable resin layer 11 and a picture pattern layer 12 are sequentially laminated on one face of a base material 10 so as to form a decorative sheet having biodegradable property. As an another embodiment, the first degradable resin layer 11, the picture pattern layer 12, and a second biodegradable resin layer 13 may be sequentially laminated on one face of the base material 10 so as to form the decorative sheet having biodegradable property. It is appropriate that a foaming agent is mixed in the biodegradable resin layer 11 and an aliphatic polyester amide is added in the biodegradable resin layers 11 and 13. Further, it is also suitable to form an embossed pattern 15 on the biodegradable resin layer 13. As appropriate examples of the biodegradable resin, a biodegradable polylactic acid resin, a biodegradable aliphatic polyester amide resin and the like can be named.

2. Description of the Related Art Conventionally, wallpaper for walls and ceilings, furniture,
As decorative sheets used for surface decorative materials such as interior doors and sliding doors, a paper base material is coated with an expandable polyvinyl chloride resin paste, printed on it, and thermally foamed. There is a decorative sheet made by printing a vinyl-colored film and laminating a transparent film such as vinyl chloride or polyethylene on it, but at the stage of discarding them, incineration pollutes the environment especially, so it is landfilled. However, since it is hardly decomposed with films such as polyvinyl chloride and polyethylene, the ground is unstable and it is unsuitable for construction, and with the increase of garbage in recent years, it has become a major environmental problem .

Since the biodegradable decorative sheet of the present invention does not use a vinyl chloride resin, not only does it not generate toxic gas such as chlorine gas when incinerated at the stage of discarding it, but also does not generate it. Even when landfilled in the soil, unlike conventional vinyl chloride or polyethylene, it is completely decomposed by microorganisms in the soil and turned into soil, so that the ground can be stabilized and the land can be used effectively. It can be used and has the effect of not causing environmental problems.
