Imaging media capable of displaying sharp indicia |
摘要 |
Improved sheet material of the type where a base sheet is provided with an opaque microvoid-containing layer which can be locally transparentized by applying a colorless liquid which is a non-solvent for the layer. Indicia remain more sharply defined by including in the layer an organic polymer which jellifies in the presence of the liquid and blocks lateral migration.
