Abstract

Official abstract text for this publication.

The objective of the present invention is to provide a thermosensitive recording medium excellent in color developing property, especially excellent in bar code readability, under severe environment. Provided is a thermosensitive recording medium having a thermosensitive recording layer comprising a colorless or pale colored electron donating leuco dye and an electron accepting color developing agent on a substrate, wherein the thermosensitive recording layer contains a specific sulfone compound and a specific urea-urethane-based compound in a specific ratio.

First claim

Opening claim text (preview).

What is claimed is: 1. A thermosensitive recording medium having a thermosensitive recording layer comprising a colorless or pale colored electron donating leuco dye and an electron accepting color developing agent on a substrate, wherein the thermosensitive recording layer contains 4-hydroxy-4′-benzyloxy diphenyl sulfone and an urea-urethane-based compound represented by the general as the electron accepting color developing agent, wherein the content of the urea-urethane-based compound represented by the general Formula 2 is 0.14 parts by weight to 1.0 part by weight per 1 part by weight of the 4-hydroxy-4′-benzyloxy diphenyl sulfone.
