ABSTRACT:
A method of preparing a prelaminate for a safety glazing which involves providing a thermoplastic interlayer having a first air removal surface which includes a multiplicity of microscopic embossments of substantially identical shape integrally projecting from the plane of one side of the interlayer in a regular pattern of rows and a second air removal surface on the other side of the interlayer which is different from the first air removal surface and includes a multiplicity of microscopic peaks and valleys of varying heights and depths arranged in an irregular, non-linear pattern, interposing the interlayer between two layers of glass and deairing the interfaces with the glass layers during which the first air removal surface is partially transferred to and imposed on the second air removal surface to provide deair paths of reduced obstruction.
