PURPOSE:To improve the strength of a coated film by adding an adsorbent for an org. solvent to a paint. CONSTITUTION:If a material having high affinity to an org. solvent is added to a paint and is used as an adsorbent, the evaporation of the org. solvent in the stage of curing thermally the coated film delays and the coated film is made porous. When a liquid lubricant is at the same time coated on the surface of the coated film, the lubricant infilters the fine pores owing to an adsorption effect of the adsorbent for the liquid lubricant thus improving the strength of the coated film. The amt. of the adsorbent to be added is preferably 0.1-20pts.wt. by the whole weight of the coated film as 100pts.wt. >=1 Kind among active carbon, silica, zeolite, molecular sieving carbon, molecular sieves and active alumina are used as the adsorbent.
