Abstract
According to the present invention, a coat is formed by applying a coating composition comprising an epoxy resin obtained by a bisphenol represented by the formula: ##STR1## wherein R.sub.1 and R.sub.2 represent a hydrogen atom or an alkyl group containing from 1 to 3 carbon atoms and a curing agent, to a substrate; and thereafter contactings the resulting coat with a liquid such as warm water or hot water in a one stage or multistage process. The thus formed coat is excellent in properties such as heat resistance, particularly erosion resistance adhesive properties and resistance to leaching of organic constituents contained in the coat exposed to hot water.
