Abstract
An archival photoprint laminate process employs a dye-bleach developed transparent print laminated on both sides using a polyurethane bonding material which includes UV inhibitors, and then fusing those three layers between opposing sheets of glass in a standard type heat-laminating process. An aliphatic polyether urethane extruded sheet is employed as the bonding material. The print is developed on ILFORD CC.F7 transparent display film by the Ilford CIBACHROME II process.
