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.
Claims23
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.
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.
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.
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.
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.
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.
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.
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.
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.
