    • 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 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; the height, R.sub.z, of the embossments and peaks being less than about 75 microns and the distance, S.sub.m, between embossments and peaks being less than about 650 microns. During deairing in forming a safety glazing, the first air removal surface is partially transferred to and imposed on the second air removal surface to provide deair paths of reduced obstruction.
    • 一种热塑性中间层,具有第一空气除去表面,该第一空气除去表面包括大量相同形状的微观浮雕,其形状从中间层的一侧的平面以规则图案一体地突出,另一侧的第二空气除去表面是中间层的另一侧 不同于第一除气表面并且包括以不规则的非线性图案排列的多个不同高度和深度的微观峰和谷; 凸起的高度Rz和峰值小于约75微米,并且凸起和峰之间的距离Sm小于约650微米。 在形成安全玻璃的脱气期间,第一除气表面被部分转移并施加在第二除气表面上,以提供减少障碍物的脱气路径。
