Description of the Related Art Mats such as desk mats, table mats and place mats are conventionally made of a resin composition in which a plasticizer, a stabilizer and the like are mixed with a polyvinyl chloride resin. This mat made of polyvinyl chloride has excellent properties such as good transparency and flexibility, but the plasticizer bleeds out to the mat surface during use. However, there is a disadvantage that undesired phenomena such as the printing ink of the copy paper sandwiched between the sheets sticking to the surface of the desk mat are caused.

る。[0003] Therefore, in recent years, mats made of resin other than polyvinyl chloride have been studied.
Previously, a desk mat using a copolymer of ethylene and an alkyl (meth) acrylate as a material was proposed (Japanese Utility Model Laid-Open No. 6-21442). However, since mats such as desk mats are as thick as 1 to 3 mm, even when a material having a considerably high transparency is used, the transparency of the product is reduced. Copolymers of ethylene and alkyl (meth) acrylate are also resins with good transparency, but when they are made into mats such as desk mats, they are somewhat dirty, and they are more difficult than mats made of polyvinyl chloride. The product evaluation is slightly inferior due to lack of transparency.

It has been conventionally known to provide a gas barrier, improve gas barrier properties, improve heat sealing properties, improve transparency, and improve mechanical properties. However, these are all techniques for enhancing the properties of a thin stretched polyolefin film for packaging as a packaging material.

The copolymer is preferably composed of 60 to 95% by weight of ethylene and 5 to 40% by weight of methyl methacrylate. Thus, in the present invention, a product excellent in transparency can be obtained by using the ethylene-methyl methacrylate copolymer. If other resins are mixed and used, transparency will be impaired. Examples of the resins to be mixed include polypropylene, low-density polyethylene, high-density polyethylene, linear low-density polyethylene, and ultra-low-density polyethylene.

強度が劣るようになり好ましくない。The resin component (B) of the present invention is a petroleum resin, a rosin resin, a terpene resin, a cumarone-indene resin or a hydrogenated product thereof. In particular, hydrogenated products of these resins are preferred. The petroleum resin, aliphatic petroleum resin, aromatic petroleum resin, alicyclic petroleum resin is used, for example, C 9 petroleum resins complete hydrogenation of the softening point 100 to 150 ° C. are preferred. Softening point 100-15
A hydrogenated terpene resin at 0 ° C. is also preferably used. The resin component (B) functions to improve the transparency of the resin component mainly composed of the ethylene-methyl methacrylate copolymer (A). The resin component of (B) is blended in an amount of 1 to 30% by weight based on the resin component of (A). If the amount is less than 1% by weight, the effect of improving transparency is insufficient, and if it exceeds 30% by weight, the strength is deteriorated, which is not preferable.

The resin component of (A), the resin component of (B), and, if necessary, an ultraviolet absorber, an antistatic agent, an antioxidant, a pigment, an anti-blocking agent, and the like are mixed, and the mixture is used with a T-die. Then, the sheet is extruded into a sheet, and the obtained sheet is cut into a mat without being stretched. The thickness of the sheet is usually 1 to 3 mm. Although the transparency of a film or sheet generally improves when stretched, the mat of the present invention has remarkably excellent transparency even without stretching.

を高め、表面を傷付きにくくする。A mat made of a resin mixture in which the resin component of (A) is blended with the resin component of (B) has improved transparency due to the blending of the resin component of (B). There is a tendency to become tacky. In the case of mats such as desk mats, table mats and place mats, there are various inconveniences when the surface thereof has adhesiveness. Therefore, it is preferable to provide an anti-adhesion layer on at least one surface of the mat. This anti-adhesion layer is formed of a resin layer of, for example, a urethane-acrylic resin having excellent transparency and no tackiness. A particularly preferred resin layer is a UV-curable resin layer, for example, a resin layer formed using a urethane-acrylate-based UV-curable paint. This ultraviolet-curable resin layer also increases the hardness of the mat surface and makes the surface hard to be damaged.

付き易さを改善してもよい。Further, by blending resin fine particles in the anti-adhesion layer, the light reflectivity of the mat surface is adjusted,
The reflection can be softened. The resin fine particles are fine particles of a nylon resin, an acrylic resin, a urethane resin, a benzoguanamine resin or the like, and preferably have a particle size of 5 to 40 μm.
In addition, when applying the anti-adhesion layer containing the resin fine particles to the mat surface, a part of the resin fine particles is projected to the surface of the anti-adhesion layer, thereby improving the surface cracking and scratching easiness when bending the mat. May be.

マットとして有用である。The mat using the above-mentioned ethylene-methyl methacrylate copolymer (A) or a resin mixture containing the same as the main component has a lower transparency as the thickness is increased, resulting in a poor product evaluation. However, by blending the resin component (B), the transparency can be greatly improved. Further, the surface of the mat becomes tacky by blending the resin component (B), but the tackiness can be prevented by providing an anti-stick layer on this surface. In addition, by blending the resin fine powder into the anti-adhesion layer, it is possible to improve the reflectivity of the mat surface and the ease of cracking and damage. Therefore, the mat of the present invention
It is useful as a mat such as a desk mat, a table mat, and a place mat.
