Thermally developable materials containing cationic overcoat polymer |
摘要 |
Thermally developable imaging materials have an outermost protective layer that is composed of one or more hydrophilic film-forming components. The predominant film-forming component is a positively-charged latex polymer that has cationic groups. The charged latex polymer is present as latex particles that have prepared in the presence of a non-ionic or cationic stabilizer in an amount of at least 0.5% (by weight) that has an HLB value of 7 to 20. The nonionic or cationic stabilizer becomes associated with the latex polymer particles. Both thermographic and photothermographic materials can be prepared with such protective layers.
