DEFINITION

Classification: 156/99

(under subclass 60) Processes which are directed to joining in face to face adhesive contact at least two laminae having a glass composition by adhesive interlayer in which the lamina and interlayer have the property of transmitting rays of light so that bodies can be seen therethrough.

(1) Note. This and indented subclasses is residual to treatments, per se, of laminated glass sandwiches not

provided for in this or other classes, e.g., edge sealing, per se, as provided for in subclass 107 of this class (156).

(2) Note. The sandwich is optically transparent through the adhered areas as distinguished from air spaced lamina adhered at the edges only of subclass 109 below.

38, for a light transmissive mass (which could comprise plural layers) having a frame or opaque border therearound (e.g., stained glass) and subclasses 426+ for a plural layer stock material product including a layer of glass.
