A substrate having the following layers in the following order thereon; first dielectric layer, first layer with infrared reflection properties, second dielectric layer, second layer having infrared reflection properties, and third dielectric layer. The thickness of the first layer with infrared reflection properties is 50% to 64% of that of the second layer having infrared reaction properties. The optical thickness of the first dielectric layer is greater than the thickness of the third dielectric layer by at least 100%. The substrate and the layers together exhibit an external reflection color in the range of blue to blue-green at both 0.degree. and 60.degree. incidence angles.

A hydraulic antivibration support comprises first and second rigid strength members, an elastomer body having a thick wall interconnecting the two rigid strength members and defining a hydraulic working chamber, and a thin wall defining a hydraulic compensation chamber which is connected to the working chamber via a narrow channel. The elastomer body is extended by a flexible elastomer tongue which is received in a slot-shaped housing of the second strength member, said housing including a face in communication with the working chamber and a face in communication with the compensation chamber, both faces being closable in alternation by the flexible tongue.
