DEFINITION

Classification: 523/172

Pavement or sign marking or reflex reflecting composition or process of preparing:

(under subclass 1) Subject matter wherein a composition utilized either as an applied marking for pavements (e.g., roads, streets, highways, aircraft landing strips, etc.) or for signs, e.g., for defining traffic lanes, pedestrian crosswalks, traffic instruction, etc., or as an applied reflex-reflector is claimed or solely disclosed or to processes of preparation thereof.

(1) Note. For an explanation of patent placement referring to claimed or solely disclosed, see (in the class definition) the section of SEARCH THIS CLASS, SUBCLASS that refers to this subclass.

(2) Note. A reflex-reflector composition is defined to be either a composition applied to a reflective surface to return light back toward its source in a brilliant cone with the axis of the cone essentially common with the incident beam of light or a composition to exhibit to a viewer both true daytime color and true nighttime color.

(3) Note. A road surface paving composition is not considered to be a pavement marking composition and is therefore excluded herein.
