1. A method of coloring the surface of an object comprising a first step of providing a sheet of transfer material consisting essentially of a substrate, a layer of thermoplastic material formed on said substrate, and a design layer formed on said layer of thermoplastic material, said thermoplastic material being heat-sensitive and characterized in being non-tacky at room temperatures, further characterized by being activated upon being heated and remaining activated for a predetermined period of time after termination of said heating, solidifying to effect complete adhesion upon lapse of said predetermined period of time;

  • a second step of heating said sheet to a temperature at which said thermoplastic layer becomes tacky, and a third step of transferring said design layer from said sheet to the surface of said object;

    said transferring step comprising pressing a transfer pad against said design layer of said sheet of transfer material so that said design layer and said thermoplastic layer are transferred to the surface of said pad, and then pressing said pad surface with said transferred layers thereon against the surface of said object so that said design and thermoplastic layers are transferred from said pad surface to said surface of said object.
