Claims
- 1. A thermosensitive recording material comprising a matrix of an electrically insulating, film-forming thermoplastic resin and, dispersed as a fine powder in the matrix, at least one linear aliphatic dicarboxylic acid having at least 13 carbon atoms and a melting point of not more than 150.degree. C. or its ammonium salt, the amount of the linear aliphatic dicarboxylic acid or its ammonium salt being 5 to 40 parts by weight per 100 parts by weight of the resin matrix.
- 2. The recording material of claim 1 wherein the linear aliphatic dicarboxylic acid contains from 13 to 26 carbon atoms.
- 3. The recording material of claim 1 wherein the thermoplastic resin has a glass transition temperature of not more than 70.degree. C.
- 4. The recording material of claim 1 wherein the thermoplastic resin has a softening temperature of about 75.degree. to about 170.degree. C.
- 5. The recording material of claim 1 wherein the thermoplastic resin is an acrylic resin.
- 6. The recording material of claim 1 which further comprises a phenolic compound.
- 7. The recording material of claim 6 wherein the amount of the phenolic compound is at most 20 parts by weight per 100 parts by weight of the resin matrix.
- 8. A thermosensitive electrostatic recording material comprising a thermally stable substrate having at least one electrically conductive surface and applied to the conductive surface of the substrate, a thermosensitive recording layer, said thermosensitive recording layer comprising a matrix of an electrically insulating, film-forming thermoplastic resin and dispersed as a fine powder in the matrix, a linear aliphatic dicarboxylic acid having at least 13 carbon atoms or its ammonium salt.
