an ornamental heat transfer is described which is especially adapted for application to nylon fabrics . the ornamental heat activated transfer includes an upper layer which is generally a thermoset layer , cloth such as twill or flock which is bonded to a lower layer . the lower layer is an uncured linear saturated polyester film which includes a heat activatable isocyanate curing agent . upon application of the transfer to nylon the transfer is heated which melts the uncured saturated polyester and activates the curing agent . thus while the linear saturated alkyl polyester is in a molten state the curing agent causes the polyester to cure in tight confinement with the nylon fabric .
