材の表面に貼り合わせることができなかった。By the way, in recent years, the above-mentioned polyvinyl chloride-based cosmetic sheet is used in consideration of human impact caused by generation of toxic gas when burned and environmental protection in waste disposal. A user strongly demands the development of a decorative sheet that replaces the sheet, and a polyolefin-based decorative sheet in which a pattern is printed on a polyolefin-based sheet has been considered as an alternative to the polyvinyl chloride-based decorative sheet. However, the polyolefin-based decorative sheet does not get wet with an acrylic resin-based or vinyl acetate resin-based water-based adhesive having good workability, which has been widely used when pasting a polyvinyl chloride decorative sheet to a wood substrate. Unfortunately, these aqueous adhesives could not be attached to the surface of the wood base material.

る。BEST MODE FOR CARRYING OUT THE INVENTION The polyolefin-based decorative sheet of the present invention will be described in detail below based on an embodiment shown in FIG. Usually, a pattern (12) such as wood grain or an abstract pattern is printed on the surface of a colored opaque or translucent polyolefin-based sheet (11) by a gravure printing method, an offset printing method, a silk screen printing method, etc. Depending on the situation, in order to protect this pattern from external forces such as rubbing and scratching, a transparent plastic film is laminated on the pattern surface, or a transparent varnish is applied to protect the pattern (1
Form 3). On the back surface of the polyolefin sheet (11) printed with this pattern, which is to be bonded to the wood base material, a silica component (P) having an average particle diameter of 1 to 2 μm and a resin component (R) ratio of 0.6 <P. /R<0.9 is contained, and a polyurethane back coat layer having a thickness of 1 to 10 μm and containing no leveling agent or a lubricant in other additives is formed by a gravure printing method or the like, The polyolefin-based decorative sheet (10) of the present invention is produced.

ず使用することもできる。The polyolefin-based decorative sheet (10) of the present invention, as shown in FIG. 2, is a wood-based base material (20) of a plant fiber material such as natural wood, plywood or particle board.
When the decorative board (100) is manufactured by bonding it to the surface of the sheet, it is bonded to the acrylic resin-based or vinyl acetate resin-based water-based adhesive (30) through the polyurethane-based backcoat layer (14) having adhesiveness. For water-based adhesive (30)
It becomes possible to adhere the polyolefin-based decorative sheet (10) to the wood base material (20) by using. Besides,
This polyurethane-based back coat layer contains silica, and the surface condition becomes uneven, resulting in a wide contact area with the adhesive, and also contains an additive such as a leveling agent or a lubricant that inhibits wetting with the adhesive. Since this is not done, the adhesion of the decorative sheet to the wood base material is further improved. In addition,
If it is an adhesive that adheres to the polyurethane back coat layer,
It is not limited to an acrylic resin-based or vinyl acetate resin-based water-based adhesive and can be used.

First, a grain pattern is printed by a gravure printing method on one surface of a 100 μm-thick colored polyolefin sheet containing polypropylene as a main component, and a transparent layer 10 is formed as a protective layer on this pattern surface.
A 0 μm thick stretched polypropylene film was dry laminated, and on the other side, a Lamister Em additive manufactured by Toyo Ink Mfg. Co., Ltd. (10 wt% silica, 14 wt% polyurethane resin, P / R = 0.71) Was applied by a gravure printing method to form a polyurethane-based backcoat layer having a thickness of 1 μm, and a polyolefin-based decorative sheet of this example was produced. No blocking accident occurred in the rolled-up state during manufacturing or storage.
