Heat sensitive recording material |
| abstract |
A heat sensitive recording material which is comprised of a support having thereon at least a transparent heat sensitive layer excellent in freshness-keeping property is disclosed. The transparent heat sensitive layer is obtained by coating a solution obtained by mixing a microcapsule containing a colorless or light colored electron donating dye precursor with an emulsion prepared by dispersing a color developer dissolved in an organic solvent, which is slightly soluble or insoluble in water, into an aqueous solution containing both of a surface active agent and water soluble polymer. The stabilities of emulsion and heat sensitive layer are improved by using a partially saponified polyvinyl alcohol as the water soluble polymer and/or adding a metal salts of a salicylic acid derivatives into the coolor developer. A heat sensitivity of the heat sensitive recording material is improved by using a organic solvent having a boiling point lower than 150 DEG C. alone as said organic solvent and/or using a special electron donating dye precursor. An antiscratch property of the heat sensitive layer is able to improve without lowering the transparency by adding a special fillers in the heat sensitive layer. |
