Abstract
Abstract A laminated material is formed of a layer of polyurethane or polyether and a layer of extruded polyester. The polyester adhesive layer, which may contain five to fifteen percent by weight of polyurethane homogeneously mixed therein, is bonded to the layer of polyurethane or polyether under pressure at a sufficiently high temperature to permit an even viscous molecular flow between adjacent surfaces of the layers. When the layer is polyurethane, the temperature is above the softening point of polyurethane so that it is high enough to remove at least enough of the toluene solvent from the layer of polyurethane so that curling is prevented. When the laminated material is applied to a material with sufficient pressure and heated sufficiently that the layer of polyester becomes adhesive, the laminated material adheres to the material against which the layer of polyester is pressed. Thus, the laminated material has particular utility as a letter, numeral, or design for a sport uniform or wearing apparel, for example, of any material.
