    • PROBLEM TO BE SOLVED: To provide a heat-sensitive recording body which is excellent in heat- resistance of the base color section. SOLUTION: This heat-sensitive recording body has a heat-sensitive coloring layer which contains a colorless or slightly tinted dye precursor and a color developer which colors the dye precursor by reacting when being heated. In such a heat-sensitive recording body, the color developer is a bisthiourea compound represented by a general formula (1), and the heat-sensitive coloring layer does not contain a sensitizer. The heat-sensitive recording body is excellent in heat-resistance of the base color section. (In the formula, X, R 1 , R 2 , R 3 , R 4 , R 5 , R 6 , R 7 and R 8 each represents a lower 1-6C alkyl group, a 1-6C alkoxy group, a cyclohexyl group, a nitro group, a cyano group, a halogen atom, or a hydrogen atom. Y represents S or SO 2 . The letter m is an integer of 1 to 3.). COPYRIGHT: (C)2003,JPO
    • 要解决的问题:提供一种基色部分的耐热性优异的热敏记录体。 解决方案:该热敏记录体具有含有无色或稍微着色的染料前体的热敏着色层和通过在加热时反应而使染料前体着色的彩色显影剂。 在这样的热敏记录体中,彩色显影剂是由通式(1)表示的双硫脲化合物,并且热敏着色层不含增感剂。 热敏记录体的基色部分的耐热性优异。 (式中,X,R SB 1,R SB 2,R SB 3,R SB 4,SB SB R 5,SB 7,R SB 7,R SB 8,各自表示低级1-6C烷基,1-6C 烷氧基,环己基,硝基,氰基,卤素原子或氢原子,Y表示S或SO 2 ,字母m为1〜3的整数。 。 版权所有(C)2003,JPO
