DEFINITION

Classification: 359/540

Placed on top of binder (e.g., resin, asphalt, glue, etc.):

(under subclass 536) Subject matter wherein the binder is first placed on the surface and subsequently, prior to hardening of the binder, the spheres are placed thereon to ensure that they are fixed to the surface via the binder.

(1) Note. This includes exposed spheres which are glued to the surface, resulting in an exposed glass-sphere surface.

(2) Note. Spheres which are not completely surrounded by the binder belong in this subclass.

(3) Note. A monolayer (single) of spheres on a binder belong in this subclass.
