Patent number: 4828638Abstract: Transfer sheets and ribbons having a thin foundation carrying two superposed heat-transferable coatings. The base coating is cohesive, nonadhesive, substantially colorless and free of coloring matter and oil, and functions as a heat sink to insulate the top layer against excessive melting. The supercoating is more adhesive than the base coating, contains coloring matter and has excellent bonding properties for the base layer and also for receptive sheets including those having very smooth or glossy surfaces and relatively smooth closely-woven fabrics.Heat-transferred images are strongly adhered to the receptive sheet and produce no visible loss of clarity or sharpness if smudged by contact since the portion of the images exposed to contact is free of coloring matter.Type: GrantFiled: June 24, 1987Date of Patent: May 9, 1989Assignee: Chemicraft International, Inc.Inventor: Albert E. Brown
