## Abstract

Paper is disclosed for use in making repositionable or removable adhesive labels. The adhesive can be applied in patches or discrete areas to the paper or to a layer of material that cleans rollers in the manufacturing line and/or in printers. The adhesive can be applied in single or multiple layers. The paper is light weight paper and preferably thermal paper for use in POS printers.

## Claims

### Claim 1

Paper, suitable for use as removable or repositionable labels, comprising:
a paper substrate, having a weight of less than about 70 gsm, a width extending between lateral edges, a longitudinal axis extending along the center of the width, a first side and a second side,
the first side supporting at least one release layer;
the second side supporting at least one layer of adhesive;
at least one layer of material between the adhesive and the paper, which material aids in cleaning printer components when the labels are being printed;
the adhesive being in the form of a plurality of substantially discrete adhesive areas having a dry weight per unit area of the paper, the adhesive areas being separated by adhesive having a lower dry weight per unit area of the paper and/or by exposed cleaning material.

### Claim 2 (depends on 1)

Paper as claimed in claim 1, wherein the lower dry weight per unit area is about 20-50% of the higher dry weight per unit area.

### Claim 3 (depends on 1)

Paper as claimed in claim 1, wherein the lower dry weight per unit area is 2 gsm or less and the higher dry weight per unit area is 4 gsm or more.

### Claim 4 (depends on 1)

Paper as claimed in claim 1, wherein the adhesive areas are separated by adhesive and adhesive extends across the width of the paper, except for an adhesive free zone extending along one or both of the lateral edges of the paper.

### Claim 5 (depends on 1)

Paper as claimed in claim 1, wherein the areas are separated by adhesive and adhesive extends continuously along the paper.

### Claim 6 (depends on 1)

Paper as claimed in claim 1, wherein the adhesive areas are arranged in one or more columns along the paper.

### Claim 7 (depends on 6)

Paper as claimed in claim 6, wherein there are at least two columns, with at least one on each side of the longitudinal axis.

### Claim 8 (depends on 1)

Paper as claimed in claim 1, wherein the adhesive areas are arranged at an angle to the longitudinal axis.

### Claim 9 (depends on 8)

Paper as claimed in claim 8, wherein the adhesive areas are angled to point in the direction of travel of the paper when it is used in a printer.

### Claim 10 (depends on 8)

Paper as claimed in claim 8, wherein the angle is about 45°.

### Claim 11 (depends on 1)

Paper as claimed in claim 1, wherein the adhesive having a lower dry weight per unit area comprises one or more layers.

### Claim 12 (depends on 1)

Paper as claimed in claim 1, wherein said adhesive comprises one or more strips of adhesive extending along the paper.

### Claim 13 (depends on 1)

Paper as claimed in claim 1, wherein the adhesive areas comprise one or more layers.

### Claim 14 (depends on 1)

Paper as claimed in claim 1, wherein the amount of adhesive on the paper is from about 6 to about 18 gsm, measured as dry weight of adhesive.

### Claim 15 (depends on 14)

Paper as claimed in claim 14, wherein the amount of adhesive is from about 8 to about 10 gsm, measured as dry weight of adhesive.

### Claim 16 (depends on 1)

Paper as claimed in claim 1, wherein the adhesive comprises a microsphere adhesive.

### Claim 17 (depends on 1)

Paper as claimed in claim 1, wherein the adhesive and the cleaning material comprise the same polymeric material.

### Claim 18 (depends on 1)

Paper as claimed in claim 1, wherein the paper is thermal paper.

### Claim 19 (depends on 1)

Paper as claimed in claim 1, having a weight of about 55 gsm.

### Claim 20 (depends on 1)

Paper as claimed in claim 1, designed for one or more commercial printers,
the adhesive areas being along the length of the roll to produce at least one repeat pattern in that direction;
each repeat pattern having a repeat length;
the spacing of the adhesive areas being configured to interact with a particular printer or printers having a platen roll to facilitate the passage of the paper through the printer(s),
the platen roll having a particular circumference;
the ratio of each repeat length to the circumference being not a whole number.

### Claim 21 (depends on 1)

Paper as claimed in claim 1, wherein the cleaning material comprises polyvinyl acetate.

### Claim 22 (depends on 1)

Paper as claimed in claim 1, wherein the primer or cleaning material comprises titanium dioxide.
