The defect known as &ldquo;applesauce&rdquo; is eliminated from laminated glass structures which include an intermediate plastic film carrying an energy reflective layer by adhering this film to one of the glass sheets of the laminate with an adhesive layer which is less than 5 mils (0.127 mm) thick.

Laminate structure and process for its production

The adhesion to plastic substrates of thick layers of functional metals having an oxide heat of formation that is greater than -40,000 calories/gram atom of metal, such as silver, copper, gold, and the like, is improved if a thin layer of a metal having an oxide heat of formation of less than -50,000 calories/gram atom of metal is present as an adhesion-promoting primer layer. When the primer layer metal has a melting point greater than 1100.degree. C., it should be present as the metal or as a substoichiometric oxide. When the primer layer metal has a melting point less than 1100.degree. C., it may be present as the metal, as a substoichiometric oxide, or as a full stoichiometric oxide. Processes for preparing these materials using sputter-depositing and reflectors incorporating these materials are also disclosed.
