PURPOSE:To provide the titled compsn. having excellent recoatability and compatibility with a chlorinated rubber, consisting of a specified phenolic resin- modified alkyd resin, a chlorinated polymer and a plasticizer. CONSTITUTION:A phenol resin-modified alkyd resin (A) is obtd. by reacting a drying oil having a phenolic resin modifier content of 1 to 15wt% and an oil length of not higher than 60% wherein at least 50wt% of a fatty component has an iodine value of not lower than 140 (e.g., linseed oil) with a polyhydric alcohol contg. at least 10wt% trimethylolethane and/or trimethylolpropane and a polybasic acid contg. at least 10wt% isophthalic acid and/or terephthalic acid. 1-60wt% component A is blended with 10-70wt% at least one chlorinated polymer (B) having a chlorine content of not lower than 50wt% selected from the group consisting of chlorinated rubber, chlorinated PE, chlorinated PP and cyclized rubber and 0-40wt% plasticizer (C) (e.g., chlorinated paraffin).
