Abstract
A masking tape for use in applications where a coating material is applied to a surface for defining a sharp edge of the portion of the surface that is coated. A masking tape may include a reinforcing strip releasably attached to the non-adhesive side of conventional masking tape comprising a substrate with an adhesive layer on one side. The reinforcing strip extends longitudinally along the length of the substrate with one edge substantially aligned with, and preferably flush with, one longitudinal edge of the substrate and acts as a separate means to cut through a coating or film more efficiently than the masking tape alone, while subsequently leaving the masking tape in place until the preferred time of removal.

A method of coating a portion of a surface with a coating material comprising the steps of:
- a. affixing to the surface a masking tape comprising an elongated base substrate having top and bottom sides and first and second longitudinal edges, with a pressure-sensitive adhesive layer formed on the bottom side of the base substrate and a reinforcing strip adhered to the top side of the base substrate, the reinforcing strip having an outer edge, wherein the reinforcing strip has a longitudinal extent co-extensive with that of the base substrate and a width no more than half that of the base substrate, and wherein the reinforcing strip is positioned on the base substrate so that the outer edge of the reinforcing strip is substantially aligned with the first longitudinal edge of the base substrate over the longitudinal extent of the base substrate, wherein the first longitudinal edge of the base substrate defines an edge of the portion of the surface to be coated;
- b. applying coating material to the portion of the surface and over the outer edge of the reinforcing strip;
- c. allowing the coating material to at least partially dry or cure;
- and
- d. removing the masking tape from the surface.

A method of coating a portion of a surface with a coating material comprising the steps of:
- a. affixing to the surface a masking tape comprising an elongated base substrate having top and bottom sides and first and second longitudinal edges, with a pressure-sensitive adhesive layer formed on the bottom side of the base substrate and a reinforcing strip removably adhered to the top side of the base substrate, the reinforcing strip having an outer edge, wherein the reinforcing strip has a longitudinal extent co-extensive with that of the base substrate and a width no more than half that of the base substrate, and wherein the reinforcing strip is positioned on the base substrate so that the outer edge of the reinforcing strip is substantially aligned with the first longitudinal edge of the base substrate over the longitudinal extent of the base substrate, the reinforcing strip having sufficient tensile strength to cut the coating material, wherein the first longitudinal edge of the base substrate defines an edge of the portion of the surface to be coated;
- b. applying coating material to the surface and over the outer edge of the reinforcing strip;
- and
- c. removing the reinforcing strip from the base substrate.

- a. applying a pressure-sensitive adhesive to the bottom side of the web of base substrate to form a base adhesive layer;
- b. adhering N/2 reinforcing strips, each having two longitudinal edges and a width less than Wa, to the web of base substrate so that the reinforcing strips are parallel to the longitudinal axis of the web of base substrate, the centers of the reinforcing strips are spaced apart by a distance of at least Wa, and no longitudinal edge of a reinforcing strip is a distance of less than Wa/2 from either longitudinal edge of the web of base substrate;
- and
- c. cutting through the reinforcing strips, web of base substrate and the base adhesive layer along N/2 reinforcing strip cut lines parallel to the longitudinal axis of the web of base substrate, one of which reinforcing strip cut lines is located on each reinforcing strip, and cutting through the base substrate and the base adhesive layer at N/2−1 base substrate cut lines parallel to the longitudinal axis of the web of base substrate, one of which base substrate cut lines is positioned between each pair of reinforcing strips located nearest each other, each base substrate cut line being at least a distance of Wa/2 away from the center of any reinforcing strip.
