  • Patent number: 6053178
    Abstract: An image transfer sheet for holding a releasable, transferable image includes a substrate comprising release material and one or more transfer layers that are releasable by heat and/or pressure and include a gel and/or a colorant. A method for forming an image transfer sheet holding a releasable, transferable image comprises depositing one or more transfer layers on a substrate comprising release material. The transfer layers are releasable from the substrate by heat and/or pressure and comprise one or more of the group consisting of a gel and/or a colorant. A method for adhering a colored image to a receiver employs an image wafer comprising one or more transfer layers each comprising gel and/or a colorant and having the shape of a transferable color image. The image wafer, which can be disposed on a substrate comprising releasable material, is placed in contact with a receiver. Heat and/or pressure is applied to the wafer, causing it to adhere to the receiver.

  • Patent number: 5823204
    Abstract: A process for removably applying coloring material to hair comprises contacting a composite fabric material to hair and compressing the hair along with the composite material while heating the hair to a temperature of at least 140 degrees Fahrenheit. The composite fabric material is a laminated structure formed from a fiberglass substrate having polytetrafluoroethylene bonded thereto. The top surface of the polytetrafluoroethylene has a water-soluble coloring material deposed thereon which is brought into contact with the hair. The hair is compressed and heated using a hair crimping device with a first jaw with a female die member is attached thereto and a second jaw with a corresponding male die member is attached thereto.
