DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a coating composition for polyolefin containing a chlorosulfonated ethylene/pinyl acetate copolymer as a component, and more specifically, a coating composition containing a vinyl acetate content of 5 to 4.
5% by weight of ethylene/vinyl acetate copolymer is chlorosulfonated to have a chlorine content of 5 to 40% by weight and a sulfuric acid content of 0.
1 to 5% by weight, and the sum of the vinyl acetate content in the raw material copolymer and the chlorine content in the chlorosulfonated product is in the range of 30 to 6% by weight. The present invention relates to a coating composition useful as a printing ink, paint, adhesive, etc., containing a copolymer as a component.

Conventionally, various binder resins have been used for coating compositions used for polyolefin films, sheets, and coating and printing of polyolefin molded products, but the following are representative resins: be.

However, coating compositions using cyclized rubber do not have sufficient adhesive properties for polyolefins and have insufficient oil resistance, making them suitable for packaging or molded products that may come into contact with oils and fats such as butter and lard. It was unsuitable as a coating agent. Furthermore, coating agents using chlorinated polypropylene as a binder resin have problems such as resin solubility, pigment dispersibility, and residual solvent, which limits their use, particularly in the food packaging field.

On the other hand, coating agents that use ethylene/vinyl acetate copolymer as a binder resin have some adhesive properties, but have insufficient solubility in solvents, pigment dispersibility, and low-temperature stability, and have not been put into practical use. A binder resin using a chlorinated ethylene/vinyl acetate copolymer that has been improved in this respect is used. However, although the above-mentioned problems of ethylene/vinyl acetate copolymer have been improved, the pigment dispersibility is still insufficient, and there are also problems with the finish of the coating due to static electricity generated during the coating or printing process on polyolefin. However, the use of anti-static agents is unavoidable as this causes baldness or flowering (flowering refers to uneven flower-shaped repellent patterns caused by static electricity), which significantly reduces the product value. It was something that

However, when an antistatic agent is used, the antistatic agent stands out on the surface of the coating film, degrading the coating performance and suitability for post-processing.

That is, in the present invention, an ethylene/vinyl acetate copolymer having a vinyl acetate content of 5 to 45% by weight is chlorosulfonated to have a chlorine content of 5 to 4% by weight and a sulfur content of 0.1 to 5% by weight.
and a chlorosulfonated ethylene/vinyl acetate copolymer in which the sum of the vinyl acetate content in the raw material copolymer and the chlorine content of the chlorosulfonate is in the range of 30 to 6% by weight. It relates to a coating composition for polyolefin containing as follows.

If the vinyl acetate content in the raw material copolymer used in the chlorosulfonated ethylene/vinyl acetate copolymer according to the present invention is less than 5%, low-temperature adhesion and solubility in solvents will decrease, and if it exceeds 45%, the vinyl acetate content will decrease. Blocking resistance decreases.

Further, if the chlorine content in the chlorosulfonate is less than 5%, problems will arise in compatibility with other resins added as necessary, and if it exceeds 45%, blocking resistance will be significantly reduced. In addition, the sulfur content in the chlorosulfonate is 0.
.. If it is less than 1, no antistatic effect will be obtained, and the coating film will develop static-induced whiskers or blooms, lowering its commercial value, and the pigment dispersibility will be insufficient, and adhesion and rubbing resistance will decrease. On the other hand, if it exceeds 5%, although the adhesion is excellent, the drying properties are reduced, causing problems in workability.
What is further required is that even if the chlorosulfonated ethylene/vinyl acetate copolymer is within the above range, the sum of the vinyl acetate content in the raw material copolymer and the chlorine content in the chlorosulfonated product is 30%. The desired effect cannot be obtained unless the content is in the range of 6 to 6% by weight, so it is necessary to adjust the vinyl acetate content and chlorine content, respectively.
