## Abstract

A hand-held correction or marking material (20) comprises a solid synthetic matrix (26) containing a correction or marking material. The matrix is such that when it is drawn over and in contact with a paper or similar surface, it deposits thereon as a thin dry coating which is immediately hard. The matrix can liquify temporarily in the contact area and then immediately resolidify in the form of the thin coating. The correction materials comprise an opacifier such as titanium dioxide, and the marking materials comprise a colored pigment or dye in the matrix.

## Claims

### Claim 1

A correction or marking material which comprises a correction or marking agent dispersed in a solid carrier, which carrier upon working contact with a substrate becomes temporarily liquid to deposit thereon as a dry coating including said agent therein and having essentially the same composition as said correction or marking material.

### Claim 2

A correction or marking material which comprises a correction or marking agent in a solid synthetic matrix, which material in use, when moved in contact with and relative to a substrate, liquefies at least partially to deposit itself on the substrate as a thing coating of matrix and agent, which coating immediately resolidifies to form a dry layer having essentially the same composition as said correction or marking material.

### Claim 3 (depends on 2)

A material according to claim 2, wherein the correction agent is an opacifying agent.

### Claim 4 (depends on 3)

A material according to claim 3, wherein the opacifying agent is finely divided titanium dioxide.

### Claim 5 (depends on 2)

A material according to claim 2, wherein the marking agent is a coloured pigment or dye.

### Claim 6 (depends on 2)

A material according to claim 2, wherein the marking agent is a fluorescent material.

### Claim 7 (depends on 2)

A material according to claim 2, wherein the matrix comprises a mixture of a highly crystalline aromatic fused ring compound and a long chain aliphatic alcohol.

### Claim 8 (depends on 7)

A material according to claim 7, wherein the fused ring compound is abietic acid or a derivative thereof, and the long chain alcohol is selected from the group consisting of stearyl, myristyl, cetyl or lauryl alcohol.

### Claim 9 (depends on 2)

A material according to claim 2, wherein the carrier or matrix comprises a mixture of a biphenyl compound and a long chain aliphatic alcohol.

### Claim 10 (depends on 9)

A material according to claim 9, wherein the biphenyl compound is a carboxyl-substituted biphenyl and the alcohol is cetyl or myristyl alcohol.

### Claim 11 (depends on 2)

A material according to claim 2, wherein the carrier or matrix is in the form of a rigid stick.

### Claim 12

An instrument comprising a housing and within said housing a rigid stick comprising a correction or marking agent in a solid synthetic matrix, which material in use, when moved in contact with and relative to a substrate, liquefies at least partially to deposit itself on the substrate as a thin coating of matrix and agent, which coating immediately resolidifies to form a dry layer having essentially the same composition as said correction or marking material.

### Claim 13

A correction or marking material which comprises a correction or marking agent in a solid carrier comprising a highly crystalline aromatic fused ring compound and a long chain aliphatic alcohol.

### Claim 14 (depends on 13)

A material according to claim 13, wherein the fused ring compound is abietic acid or a derivative thereof, and the long chain alcohol is selected from the group consisting of stearyl, myristyl, cetyl or lauryl alcohol.

### Claim 15

A correction or marking material which comprises a correction or marking agent in a solid carrier comprising a biphenyl compound and a long chain aliphatic alcohol.

### Claim 16 (depends on 15)

A material according to claim 15, wherein the biphenyl compound is a carboxyl-substituted biphenyl and the alcohol is cetyl or myristyl alcohol.

### Claim 17 (depends on 15)

A material according to claim 15, wherein the carrier or matrix is in the form of a rigid stick.

### Claim 18 (depends on 15)

A material according to claim 15, wherein the agent comprises finely divided titanium dioxide.

### Claim 19 (depends on 15)

A material according to claim 15, wherein the agent comprises a fluorescent material.

### Claim 20

A method comprising contacting a substrate with a correction or marking material comprising a correction or marking agent dispersed in a solid carrier, said carrier upon contact with said substrate becoming temporarily liquid to deposit thereon as a dry coating having essentially the same composition as said correction or marking material.

### Claim 21

A method comprising contacting a substrate with a correction or marking material comprising a correction or marking agent in a solid synthetic matrix, said material when contacted with said substrate, liquefies at least partially to deposit itself on the substrate as a thin coating of matrix and agent, which coating immediately resolidifies to form a dry layer having essentially the same composition as said correction or marking material.

### Claim 22

A method comprising contacting a substrate with a correction or marking material which comprises a correction or marking agent in a solid carrier comprising a highly crystalline aromatic fused ring compound and a long chain aliphatic alcohol to transfer said correction or marking material to said substrate.

### Claim 23

A method comprising contacting a substrate with a correction or marking material which comprises a correction or marking agent in a solid carrier comprising a biphenyl compound and a long chain aliphatic alcohol to transfer said correction or marking material to said substrate.
