The release of the present invention solves the problem of the protective article of the present invention in the field for simplifying the removal of the surface of the protective article by means of the removal of the protective object, whereby it can be used to provide cleaning for items such as tables: In addition, protective objects: 'or provide a clean surface for changing diapers. ::; such as cleaning the table, she is born 'includes easy to apply and _= objects show a number of unique, stainless steel, noodle items and easy to remove in such as ',, octah metal, Polyplastic (Formica), 124363.doc 200825149 No residual adhesive on the surface of granite, wooden laminate and ceramic surfaces. In addition, since the article can be coated with an adhesive while printing with ink, the production cost of the article can be significantly lower than the production cost using conventional techniques. SUMMARY OF THE INVENTION In one embodiment, the present invention provides a protective article comprising: (a) a flexible substrate having opposite first and second major surfaces; and (b) an arrangement of such a pressure sensitive adhesive for defining an adhesive surface on at least one of the major surfaces, wherein the adhesive is provided in a discontinuous manner, defining a bonded region and a non-bonded region, and further wherein The protective article has an 18 〇 between about 2 g/in and about 500 g/in. Peel adhesion. In another aspect, the invention provides a method of temporarily protecting a surface&apos; which comprises the step of applying a protective article to a surface adjacent to a food preparation area. In another aspect, the invention provides a method of forming a clean surface. 10 In another example, the invention provides a method for manufacturing a protective article, (a) providing a flexible substrate having first and second opposite major surfaces; (b) optionally in the polymeric substrate Printing a layer of ink on the first major surface, (c) printing a low-adhesive back coating on the second major surface, and (d) bonding a pressure sensitive adhesive in a certain manner The agent is printed on the ink layer such that the resulting adhesive is provided in the form of a discontinuous pattern in the range of 0.2 to 15 g/m2 of the total coating weight of the printed adhesive. In a particular aspect, the present invention provides a roll of a protective adhesive sheet. The roll of the protective sheet comprises: a film formed of a polyester film having a thickness of not more than about 25 microns, 124363.doc 200825149 degrees and having the opposite a first substrate and a second main surface of the substrate; - provided on the second major surface at a thickness of less than about 2 microns: a low adhesion back coat based on an amine based f vinegar; An ink print pattern having a thickness of less than about 2 microns on the major surface; and a resettable fine bond adhesive based on at least the upper surface of the main surface to thereby bond the surface. The adhesive is provided in a continuous coating and non-bonding at a coating weight of 〇.2 to 150 g/m, 2

The zone is such that the protective sheet and the ancient one have a 180 degree peel adhesion between about 2 g/in and about 5 〇 (g). [Embodiment] Referring now to the drawings (wherein (4) reference numerals refer to the same or corresponding parts in several views), FIGS. 1-5 - generally show a protective article (7) of the present invention, including - having the opposite first And a flexible substrate of the second major surface is provided on at least one of the major surfaces to thereby define a discontinuous dust-sensitive adhesive layer of the bonding surface. The substrate and pressure sensitive adhesive are described separately. Substrate* Substrates suitable for the articles of the present invention include oriented polymeric films and non-oriented polymeric films such as polyolefins (e.g., polypropylene), polyesters (e.g., poly(p-xylene: ethylenediester), or polyethylenes (e.g., Polymer film of unplasticized polyvinyl chloride; paper; metal m-woven, knitted and non-woven fabric; foam or sponge. Preferably, the substrate is a polyethylene terephthalate film or a polypropylene film. In the embodiment, the substrate is a flame retardant material. The substrate can be oriented in a uniaxial or biaxial manner to provide an article with increased strength. The substrate typically has a thickness of no more than about 124363.doc 200825149 and even more typically no greater than about 75 μηη, more typically no greater than about 5 μμηη at about 25 μηη. The substrate may optionally be treated to facilitate application of the adhesive to the substrate. This can be accomplished, for example, by applying a chemical primer to the substrate; treating the surface by corona treatment or by flame; &lt;by other known techniques. Pressure Sensitive Adhesives Adhesives suitable for use in the present invention include any which are capable of being viscous at room temperature.

The other adhesives (4) include the adhesives which are initially tacky and which are initially non-tacky but which can be activated to become tacky. Examples of suitable pressure sensitive adhesives include those based on τ each: acrylic acid vinegar, polyoxin, poly alpha-lean hydrocarbon, polyisobutylene, rubber barrier copolymer (such as Styrene / isoprene / styrene and styrene / butadiene / styrene block copolymer), styrene butyl rubber, synthetic isoprene, natural rubber or blends thereof. The pressure sensitive adhesives can be applied by solvent H-polymerization or hot melt treatment. The pressure sensitive adhesives may or may not be crosslinked. Crosslinking can be carried out by well known methods including chemical, ionic, physical or radiation inducing methods. Details on the formulation of these types of adhesives can be found in HandbGGk Gf Pressure Sensitive Adhesive

Technology' second edition, Chapter 13 (10) (2), ^ N〇strand Reinhold Press, N.Y.). In the case of the present invention, the adhesive is a resettable adhesive, and is coated by a printing method at a total coating weight ranging from about 〇·2 to about i 5 g / m 2 . On the substrate 'to enable the adhesive to be provided in a discontinuous manner to define the bonded area and the non-bonded area. Resettable adhesives are known in the art. 124363.doc 200825149 Broadly speaking, the repositionable adhesive is a type that allows a typical substrate (such as paper and polymeric film) to be repeatedly attached to and removed from various surfaces without significant loss of adhesion strength, leaving no adhesive on the surface. The residue and the substrate are not damaged by the adhesive. Various resettable adhesives can be used in the present invention.
