物の塗膜が剥離するという問題があった。In recent years, beer, juice, sake and wine, as well as beverage cans filled with various beverages such as tea, green tea, milk drink, sports dring, etc. are being sold, and in addition to responding to the demands of consumers, There is a demand for a beverage can having a shape different from that of the conventional cylindrical beverage can, which can be markedly distinguished from the above beverage can. When manufacturing such a beverage can, the beverage can is usually subjected to draw forming, but the coating composition for improving the stability to the beverage or the like on the inner surface of the beverage can is obtained. When the coated beverage can is used, there is a problem that the coating film of the coating composition peels off at the squeezed portion.

し、本発明を完成するに至った。[Problems to be Solved by the Invention] Therefore, in view of the above-mentioned problems of the conventional techniques, the present inventors have proposed a metal can in which the coating film does not peel off at the drawn portion even when the drawing is performed. As a result of earnestly researching the coating composition for use as much as possible, it has been conventionally said that when the amount of the phenol resin in the coating composition is less than 1% by weight, various coating properties, particularly corrosion resistance are deteriorated. However, when a coating composition was further developed in which the amount of the phenol resin was further reduced to 0.4 to 0.8% by weight and a coating film was formed on the inner surface of a beverage can using the coating composition. , The amount of the phenol resin is 2
Surprisingly, compared with the coating composition of 6% by weight, not only the performance of the coating, such as adhesion, workability and drawability, does not deteriorate, but also the adhesive strength to the metal substrate is improved. The present invention has been completed by finding a completely new fact that the coating film is not peeled off in the drawn portion even when the drawing is performed.

である。[Operations and Examples] The coating composition for metal cans of the present invention has a phenol resin content of 0.4 to 0.8% (% by weight, the same applies hereinafter) contained in the coating composition which can be said to be surprising from the viewpoint of conventional techniques. And a polyvinyl chloride, vinyl chloride / vinyl acetate / propionic acid or maleic acid copolymer, and epoxy resin amount are adjusted, and the coating film of the coating composition is used in a beverage can. When it is provided on the surface, it is possible for the first time that the coating film does not peel off even when subjected to draw forming.

しい。The polyvinyl chloride is an odorless compound having excellent chemical resistance, and in the present invention, one having an average degree of polymerization of 1000 to 2100 is used. When the content of polyvinyl chloride in the coating composition is less than 50%, the viscosity of the obtained coating composition becomes too large, and a uniform coating cannot be formed. If it exceeds, stability of the resulting coating composition is impaired, so 50 to 70% is preferable.

Propionic acid or maleic acid is a component for imparting adhesion, and a weight average molecular weight of 8,000 to 20,000 is used in the present invention. When the content of the copolymer in the coating film composition is less than 25%, when the obtained coating film composition is applied to, for example, a metal material, the material of the coating film formed If the adhesiveness to is small and exceeds 40%, the viscosity of the obtained coating composition becomes too large, and it becomes difficult to form a uniform coating when applied,

ー性が低下することがある。The epoxy resin has good compatibility with other components of the coating composition of the present invention, imparts hardness and flexibility to the formed coating film, and is added to enhance chemical resistance and heat resistance. However, the epoxy equivalent of such epoxy resin is 180-
Examples include 800 bisphenol A type epoxy resin and novolac type epoxy resin. When the content of the epoxy resin in the coating composition is less than 1%, the dechlorination reaction of the vinyl chloride resin becomes more vigorous during bake-curing, resulting in deterioration of the coating and blackening. When the coating film is peeled off, and when it exceeds 6%, the coating film composition obtained is applied, the consumption amount of potassium permanganate in the formed coating film becomes large, and the flavor property is improved. May decrease.

したときに塗膜が剥離することがある。The phenol resin is used for improving the adhesive strength between the coating film formed by applying the obtained coating composition to a substrate and the substrate. Examples of such a phenol resin include a weight average molecular weight. A thermosetting resol phenolic resin having a viscosity of 100 to 700 is used, and examples thereof include bisphenol, phenolic phenol, alkyl-substituted phenol, and alkyl-substituted cresol. The content of the phenolic resin in the coating composition is 0.
If it is less than 4%, the adhesive strength between the formed coating film and the base material will decrease, and if it exceeds 0.8%, the hardness of the formed coating film will become large. The coating film may peel when applied.
