Abstract
A releasing layer is formed on a heat resistant backing sheet and a transparent thermal bonding layer is formed on top of the releasing layer to provide a coating material. The sheet of material such as photograph is mated with the coating material. When the sheet material is a photograph its emulsion side contacts the bonding layer and is passed through a heated roller assembly to bond the bonding layer to the photograph. The backing sheet and the releasing layer are then separated from the sheet material or photograph and bonding layer.
