Medical transparent thermal recording sheet

Abstract

A thermal recording sheet comprises, on one surface of square, transparent film, a thermal recording layer containing leuco dye and a coloration agent and a protection layer mainly containing water-based resin, wherein corner parts (1a, 1b, 1c, 1d) including at least one marked corner part (1a) are provided at its four corners. The corner parts (1a, 1b, 1c, 1d) respectively have end edges each with radius of curvature of at least 5 mm, and the end edge of the marled corner part (1a) is provided substantially with a maximum radius of curvature or a minimum radius of curvature.

Description

[0001] This application is a Chinese invention patent application with application number 200480037350.X (title: thermal recording sheet and thermal recording sheet package; application date: 2004.10.15; earliest priority date: 2003.10.15; international application number: PCT / JP2004 / 015233; date of entering the national phase: 2006.6.14) divisional application. technical field [0002] The present invention relates to a transparent thermosensitive recording sheet for medical use using a color reaction of a leuco dye and a color developer. Background technique [0003] Thermosensitive recording sheets that use the color reaction of a leuco dye and a color developer are relatively cheap, and the recording equipment corresponding to this thermal recording sheet is compact and easy to maintain, so it has been used as a fax recording medium or a word processor and a printing recording medium for computers. has been widely applied. [0004] Furthermore, recently, as an alternat...
