Zone-coated masking material
First Claim
1. Masking material suited to vehicular surface coating operations, comprising:
- A thin, flexible base sheet having an inner surface and an outer surface and having opposing first and second longitudinal edges defining a width;
a first pressure-sensitive adhesive layer applied longitudinally along at least the first edge on the inner surface of the sheet, the adhesive layer having a width substantially less than that of the base sheet;
a second pressure sensitive adhesive layer applied longitudinally along the second edge on the outer surface of the sheet, the second adhesive layer having a width substantially less than that of the base sheet;
the base sheet further including a first longitudinal area on its outer surface and along the first edge which functions as a release layer, and a second longitudinal area on its inner surface along the second edge which functions as a release layer, the first and second longitudinal areas enabling the base sheet with adhesive layers to be provided in roll form and easily removed therefrom for use.

Abstract
Masking material of particular value to vehicular surface coating operations consists of a thin, flexible base sheet having opposing first and second longitudinal edges which define a width. A pressure-sensitive adhesive layer is applied longitudinally along at least the first edge on the inner surface of the sheet with a width substantially less than that of the base sheet, the base sheet further including a longitudinal area on its outer surface and along the first edge which functions as a release layer, enabling the base sheet with adhesive layer to be provided in roll form and easily removed therefrom for use. In an alternative embodiment, a second pressure-sensitive adhesive layer may applied longitudinally along the second edge of the sheet, this second adhesive layer also having a width substantially less than that of the base sheet, and the base sheet further including a longitudinal area along the second edge on the surface of the sheet other than that on which the adhesive layer has been applied which functions as a release layer. The material may or may not be adapted to withstand oven temperatures of the type used, for example, to cure paint.
