<P>PROBLEM TO BE SOLVED: To provide a new diazonium salt used as an analytical reagent or a heat-sensitive recording material and having excellent photodegradability for a light source in a 350-500 nm wavelength region. <P>SOLUTION: The diazonium salt is characterized in that the diazonium salt is represented by general formula (1) (wherein, R<SP>1</SP>denotes an oxygen atom or a sulfur atom; R<SP>2</SP>and R<SP>3</SP>denote each an alkyl group; R<SP>4</SP>, R<SP>5</SP>and R<SP>6</SP>denote each independently a hydrogen atom, a halogen atom, an alkyl group, an aryl group, an alkoxy group, an alkylthio group, an aryloxy group, an arylthio group, an alkylsulfonyl group, an arylsulfonyl group, an alkoxycarbonyl group, an aryloxycarbonyl group, an acyloxy group, an acyl group or an amino group; and X<SP>-</SP>denotes an anion) or general formula (2) (wherein, R<SP>7</SP>and R<SP>8</SP>denote each an alkyl group; and R<SP>9</SP>, R<SP>10</SP>and R<SP>11</SP>denote each independently a hydrogen atom, a halogen atom, an alkyl group, an aryl group, an alkoxy group, an alkylthio group, an aryloxy group, an arylthio group, an alkylsulfonyl group, an an arylsulfonyl group, an alkoxycarbonyl group, an aryloxycarbonyl group, an acyloxy group, an acyl group or an amino group; and X<SP>-</SP>denotes an anion). <P>COPYRIGHT: (C)2004,JPO |
