Abstract
The resin compositions for peel-off coatings comprise a certain film-forming polymeric resin, an organopolysiloxane having a polyoxyalkylene group as the side chain, and a solvent. The coating compositions applied to the surfaces of various shaped articles provide protective films thereon, and the films thus formed are tough and can exhibit an excellent peelability even after the lapse of a long period of time or after heating. The coating resin compositions are prepared by a method comprising heating the mixture of the above-named individual components at an elevated temperature, not at room temperature.
