ABSTRACT:
This invention relates to a method of decorating the surface of an article made of synthetic resin and a metal mold for decoration of the article thereby formed. More particularly, it relates to a method of manufacturing a decorated article and a metal mold for its formation characterized by: heating an endless-like transfer foil fed endless-like into a metal mold; spraying hot air from an injection mold of said metal mold together with leading said heated transfer foil into the metal mold with a surface which decorates said article through an adhesive layer facing the injection mold; sticking said transfer foil to the inner circumference wall surface of said metal mold by applying suction to the transfer foil with a pouring mold; forming a given article by injection of a synthetic resin from the injection mold after closing the injection mold and the pouring mold completely; peeling off the article from the base film of said transfer foil when said article is removed from said metal mold; and only transferring the printing layer of the transfer foil to the outer surface of the forming article.
