A curable component composed of (A) an epoxy resin containing at least 90% by weight of a bisphenol glycidyl ether and (B) an aliphatic polyamine is blended with (C) 1-xylyl-1,3-diphenylbutane, bis(.alpha.-methylbenzyl)xylene, and/or 1-xylyl-1-(3-.alpha.-methylbenzylphenyl)ethane, and (D) a coloring pigment and/or an inorganic filler to form a coating composition adapted to be coated to the inner surface of pipes through which city water passes. The composition is cured to the pipe inner surface to form a film which provides a chlorine take-up of up to 1 ppm from city water flowing in contact with the film.
