Abstract: The present invention provides a mono coating film type waterborne coating composition comprising halogen free polyolefin resin, acryl polyol, acryl emulsion, and a solvent. According to the present invention, adhesion to a polyolefin substrate is excellent, and physical/chemical properties may be maintained with a single coating film instead of the currently used dual coating films, by a halogen free waterborne composition with physical/chemical properties similar to or more excellent than the existing oil coating or halogen-containing coating composition. Since these effects may be sufficiently obtained with a single coating film, consumption of coating may be reduced about 30˜40% compared to the existing method, and particularly, cost reduction may be expected through decrease in equipment required for dual coating film, energy for drying coating film, attractive force of coating, productivity increase, and the like.
