摘要： PURPOSE:To purify the subject acid anhydride as an intermediate of dyestuffs to a high-purity substance by reacting an anthraguinonedicarboxylic acid anhydride with a secondary amine, filtering the reaction solution and subsequently adding an acid to the filtrate for hydrolysis. CONSTITUTION:An anthraquinonedicarboxylic acid anhydride of formula I (Y -Y are H, amino or OH) is reacted with a secondary amine of formula II (R and R are 1-10C alkyl, alkoxyalkyl or hydroxyalkyl) in a solvent to obtain a compound of formula III. The reaction solution is then filtered for removal of impurities and an acid (preferably hydrochloric acid, hydrobronic acid, sulfuric acid, nitric acid or phosphoric acid) is added to the filtrate for hydrolysis, thus purifying the compound of formula I. In addition, room temperature - 200 deg.C and 1-10hrs are preferable as the reaction conditions between the compounds of formulae I and II.

摘要： PURPOSE:To obtain an optical recording medium satisfactory not only in light resistance, weather resistance and sensitivity but also in application properties to a recording medium substrate by containing a specific azo dyestuff in a recording layer. CONSTITUTION:Azo dyestuff, especially azo compound expressed by Formula I, is contained in a recording layer. In the formula, X and X independently express a halogen atom, nitro group, cyano group or hydrogen atom separately and are not a halogen atom or hydrogen atom simultaneously. Also, R , R , R and R express a hydrogen atom or substituted or unsubstituted alkyl group, and R and R or R and R may form a ring via combination group. One or two layers of 1-3 sorts of near infrared radiation absorbents containing this near infrared radiation absorbent are applied or deposited onto a transparent substrate.

摘要： PURPOSE:To facilitate time conversion by providing a converting means which shifts the output of a timepiece by the deviation value of time to conversion start time when the start time of the conversion and the deviation value of time are supplied from a conversion control means. CONSTITUTION:When the timepiece 1 reaches the conversion strat time to, a comparison part 19 outputs a pulse and a switch 23 is set on a solid-line side under the control of an opening/closing control part 22. A subtraction part 10 outputs the difference between the time of the timepiece 1 and the conversion start time t0 of a register 14 and a multiplication part 13 performs multiplication by a multiplier (a) for making the advance of time fast. An addition part 12 adds the time t0 and addition part 13 adds the deviation (d) of the time, and the time to a processing time 4 becomes a(t1+t0)shown by a straight line A, so that the advance of the time is made fast by the deviation (d). Then when the timepiece 1 reaches the end time t1 of the conversion, a comparison part 20 inputs a pulse to a control part 22, which controls the switch part 23 to a dotted-line side, so that the subsequent time of the timepiece 1 is supplied to the processing part 4.
