発明を完成した。[Means for Solving the Problems] The present inventors have developed a vinylidene chloride polymer coating that can be applied directly to plastic films, particularly polyolefin plastic films with low surface energy, without providing an anchor coat layer. As a result of intensive studies to obtain an anchor coating layer on a plastic film, an emulsion composition in which a monomer having a radically polymerizable unsaturated bond was radically polymerized in the presence of vinylidene chloride polymer latex was found. It can be applied directly without any preparation, and has transparency, heat sealability,
The present invention was completed based on the discovery that a coating film with excellent water vapor whitening resistance could be provided.

It is a latex obtained by polymerizing 0 to 93% by weight and 30 to 0% by weight, preferably 20 to 7% by weight of a monomer copolymerizable with vinylidene chloride. The amount of vinylidene chloride is 70% by weight
If it is less than 1,000 yen, the resulting coating film of the emulsion composition will have poor water vapor whitening resistance, although it depends on the amount of silica used. In particular, when the amount of vinylidene chloride is within the range of 80 to 93% by weight, the heat sealability of the coating film of the final emulsion composition will be very good.

性が非常に良好となる。In the present invention, the ratio of the latex of the vinylidene chloride polymer (A) to the monomer (B) is adjusted so as not to impair the performance of the vinylidene chloride polymer (A) contained in the latex. ) 70-98% by weight
, monomer (B) 30 to 2% by weight, preferably vinylidene chloride polymer (A) 85 to 95% by weight, and monomer (B) 15 to 5% by weight. If the vinylidene chloride polymer (Δ) is less than 70% by weight, the transparency of the coating film of the final emulsion composition will be poor, and the barrier properties of the vinylidene chloride polymer will not be sufficiently expressed.
In addition, the water vapor whitening resistance is also insufficient, similar to that of acrylic polymer coating agents. On the other hand, if the vinylidene chloride polymer (A) exceeds 98 polymers, the adhesion of the coating film of the final emulsion composition to the plastic film will be insufficient. In particular, when the vinylidene chloride polymer (A) is in the range of 85 to 95% by weight, the final emulsion composition has very good transparency and steam whitening resistance.

られる。The emulsion composition of the present invention provides a coating agent that significantly improves the adhesion of the coating film and can be applied to plastic films, particularly polyolefin films, without the need for providing an anchor coat layer. Although we cannot pinpoint the cause of the remarkable improvement in adhesion, the fact that chlorine atoms are observed in every particle of the emulsion particles suggests that they are not simply a blend of particles, but form particles with a multilayer structure, and that the particles are close to the particle surface. It is considered that the portions were modified with the polymer of monomer (B), and the adhesion of the coating film was improved.
