DEFINITION

Classification: 428/322.2

Indefinite plurality of similar impregnated thin sheets (e.g., "decorative laminate" type, etc.):

(under subclass 320.2) Subject matter comprising an unspecified number, greater than two, of sheets bonded together, each sheet being of similar material to the others and having at least one negligible dimension, each sheet having once been porous but having lost its porosity by being impregnated with a fluid material before or after assembly of the stack.

(1) Note. The impregnant usually is a nonfully, polymerized resin and the bonding usually includes completion of polymerization, i.e., curing, of the resin.

(2) Note. The products usually are "decorative laminates", such as those used for counter-tops, dishes, etc., sold under trade names such as Formica, Melmac, etc.
