ABSTRACT:
A novel heat release layer for use in connection with decalcomanias which include a vitreous design layer surrounded by a heat release layer and a heat activatable adhesive layer is disclosed. In particular, the novel heat release layer disclosed comprises a normally solid straight chain, primary aliphatic oxyalkylated alcohol which preferably has a molecular weight above about 1350.In addition, methods of preparing such heat release decalcomanias are also disclosed, including applying a heat release layer to a backing sheet, applying a design layer to the heat release layer, and applying a heat activatable adhesive layer to the design layer, again wherein the heat release layer is as described above.
A novel combination of heat release layers and heat activatable adhesive layers is also disclosed, including the heat release layer described above in combination with a heat activatable adhesive layer including an acrylic resin and a tackifier for the acrylic resin including a polyethylene glycol and/or a solid polyoxyalkylene derivative of propylene glycol or ethylene diamine, and including an organic solvent therein, as well as the combination of the heat release layer with a heat activatable adhesive layer including a straight chain, primary aliphatic oxyalkylated alcohol, a cellulosic derivative, a plasticizer and an organic solvent.
