Abstract: PURPOSE: Provided are an azo-based alkali-clearable disperse dye having a phthalimide structure, which has clearing ability under a weak alkali condition after dyeing polyester fiber material, and a method for dyeing the polyester fiber material by using the azo-based alkali-clearable dispersing dye. CONSTITUTION: The azo-based alkali-clearable disperse dye having the phthalimide structure is an azobenzene-based monoazo compound(formula I) and is produced by coupling-reacting a diazonium salt(formula II) of an aromatic amine compound with an aromatic aniline compound(formula III) as a coupling component. And the method for dyeing the polyester fiber material uses the azo-based alkali-clearable disperse dye(formula I) and contains an alkali clearing process using a weak alkali solution instead of a reduction clearing process using a strong alkali and a reducing agent, wherein pH of the weak alkali is 11-12. In the formula, X is hydrogen, methyl, or ethyl, Y1 and Y2 are hydrogen, methyl, methoxy, or acetylamino, and R1 and R2 are substituted or unsubstituted alkyl.

Abstract: A dye for PDP filters capable of absorbing neon lights and near infrared rays at the same time is provided, wherein a nucleophile-fixed neon-cut dye and a near infrared absorbing dye having at least one halogen substituent are covalently bonded to each other. A dye for PDP filters capable of absorbing neon lights and near infrared rays at the same time is prepared by covalently bonding (1) a neon-cut dye represented by the following formula 1 and (2) at least one near infrared absorbing dye to each other via a S_N 2 reaction using a (CH2)n-NH2 group of the neon-cut dye as a nucleophile. The at least one near infrared absorbing dye is selected from the group consisting of dithiol metal complex-based derivatives represented by the following formula 2, diimmonium-based derivatives represented by the following formula 3, and phenylenediamine metal complex-based derivatives represented by the following formula 4, which have at least one halogen substituent.
