Alkyd resin paints are inferior to acrylic resin paints in terms of corrosion resistance and weather resistance, but because they are inexpensive, they are used in various paints such as air-drying paints. In addition, studies are being conducted to improve the weather resistance of alkyd resin paints (Japanese Unexamined Patent Publication No. 62
18.477 and JP-A-62-195.055) cannot be said to sufficiently satisfy both corrosion resistance and weather resistance.

The alkyd resin used in the alkyd resin paint is not particularly limited, but it is preferably a polyester made from a polybasic acid and a polyhydric alcohol modified with an oil or fat such as soybean oil or linseed oil or a fatty acid separated from it. It is an oil-modified alkyd resin. In this case, the oil length is preferably 40 to 75%,
If it is too large, the hardness of the coating film will decrease, surface smoothness will decrease, and if it is too small, water resistance will decrease. Note that the oil length refers to the weight percentage of triglyceride in the resin, assuming that the fatty acid in the resin reacts with glycerin to form triglyceride.

The hydrogenated coumaron-indene resin used in the present invention is obtained by hydrogenating coumaron-indene resin, and can be produced by the method described in JP-A-1-213.305. . For example, it can be obtained by desulfurizing and refining gas light oil or coal tar light oil obtained by coal carbonization, polymerizing this with an acid catalyst to obtain coumaron-indene resin, and then hydrogenating this. Preferably, 0.5 to 10% by weight of coumarone, 30 to 90% by weight of indene, 2 to 20% by weight of phenols, and 0 to 30% of styrene.
This is a hydrogenated coumaron-indene resin obtained by hydrogenating a coumaron-indene resin having a monomer composition of % by weight to a hydrogenation rate of 80% or more, more preferably 95% or more. If the hydrogenation rate is less than 80%, the corrosion resistance as a paint
Weather resistance is not sufficiently improved. The amount of hydrogenated coumaron-indene resin is 2 parts by weight per 100 parts by weight of alkyd resin.
The amount is suitably in the range of 0 to 100 parts by weight; if it is too little, the modifying effect will be insufficient, and if it is too much, the coating will become too hard.

When a chlorinated polymer is blended into the coating composition of the present invention, it not only increases the adhesiveness of the coating composition and improves its affinity for adherends, but also produces effects such as relieving residual stress during coating film formation. I can do it. The chlorinated polymer used for this purpose has a chlorine content of 50% by weight or more, preferably 60% by weight.
Examples include chlorinated rubber, chlorinated polypropylene, and chlorinated polyethylene in a weight percent or more. The appropriate amount of the chlorinated polymer is in the range of 0 to 100 parts by weight per 100 parts by weight of the alkyd resin. If blended in excess, compatibility will deteriorate.
