しく印刷等の２次加工に関しては問題の多い樹脂である
。(Prior art and issues) Olefin resins are resins with excellent chemical resistance and mechanical properties, and are inexpensive and are widely used as molding materials. However, one drawback is that their molecular structure This resin has no polar groups or reactive active groups, and has poor solubility in solvents, so it is a resin with many problems in secondary processing such as printing.
その為、印刷インキの塗膜密着性を改良するには、成形
品の表面に何らかの処理を施し、インキに対する親和性
を高める必要がある。Therefore, in order to improve the coating adhesion of printing ink, it is necessary to perform some kind of treatment on the surface of the molded article to increase its affinity for the ink.
具体的な表面処理方法としては、紫外線、コロナ放電、
プラズマ放電、酸素、オゾン等により表面の親和性を高

方法がある。中でもコロナ放電処理による表面の活性化
が一般的である。Specific surface treatment methods include ultraviolet rays, corona discharge,
There are methods of increasing surface affinity using plasma discharge, oxygen, ozone, etc., and methods of roughening the surface using sandblasting and the like. Among these, surface activation by corona discharge treatment is common.

あり、酸化やイオン化により基材表面が活性化されると
いう説明がなされる事が多い。Corona discharge treatment is defined as a phenomenon in which dielectric breakdown occurs in the part of a conductor to which a high voltage is applied in the air, where there is a large potential difference near the surface, and a discharge continues. It is not clear how this will change. Due to the discharge, fine irregularities are formed,
There is a physical view that the surface is roughened, and a scientific view that the affinity improves because the surface is oxidized, but currently the prevailing view is that it is a chemical change. It is often explained that the surface of the base material is activated by ionization or ionization.

ることが知られている。Furthermore, antistatic agents are used to prevent process failures due to suction repulsion and dust absorption due to the generation of static electricity during secondary processing and secondary processing, and olefins are usually amine-based, fatty acid glyceride-based, etc. is used. Generally, amine-based drugs are said to be fast-acting, while fatty acid glyceride-based drugs are said to be long-lasting. Then, these are added in an appropriate ratio according to the required performance. The amount added is the minimum required to provide antistatic properties, but due to compatibility issues with the blend of crystalline polypropylene resin and high-density polyethylene resin, the antistatic agent stands out on the sheet surface. It is known that printability deteriorates over time due to the bloom phenomenon.

原子と１次結合をしているカルボニル。Although some aspects of the adhesion mechanism are unclear, the copolymer or terpolymer containing polar groups contained in the blend of crystalline polypropylene resin and high-density polyethylene resin is moderately scattered on the surface. However, the surface of the blend resin is in a more activated state than when corona treatment is applied to a normal resin composition. When considering the bonding state of oxygen atoms (oxidation), it can be considered that 1) it bonds to a carbon atom to form a carbonyl group or a carboxyl group; 2) it adsorbs oxygen molecules; and 2) it adsorbs ozone. It is known that the proportion of oxygen atoms on the sheet surface decreases with the passage of time.J3 Carbonyl has a primary bond with a carbon atom.
カルボキシルの酸素原子は、簡単には離脱するとは考え
られないので、酸素分子、オゾン離脱により活性が低下
すると考えられる。Since the oxygen atom of carboxyl is not considered to be easily released, it is thought that the activity decreases due to the release of oxygen molecules and ozone.

思われる。The effect of adding the ethylene-based copolymer or terpolymer having polar groups of the present invention to a blend of crystalline polypropylene resin and high-density polyethylene resin is that, compared to ordinary resin compositions, This is thought to be because the treatment effect decreases less over time due to the large number of atoms.

形成しやすい為と思われる。In addition, regarding the plume of the antistatic agent, the polar groups of the copolymer and terpolymer woven into the blend of crystalline polypropylene resin and high-density polyethylene resin ensure that the antistatic agent remains uniform throughout the sheet for a long time. This is thought to be due to the fact that it is difficult to form a peeling layer on the sheet surface. As for the action of the antistatic agent, it is desirable that it oozes out onto the surface to the extent that it has an antistatic effect and that this state is maintained for a long period of time. The reason why no effect was observed with the amine type is thought to be that the amine type tends to ooze out onto the surface of the sheet and forms an antistatic agent layer on the sheet surface more easily than the monoglyceride type.
