Solution Overview

Problem

Current triarylmethane dyes, such as Acid Blue 7 and 9, and triarylmethane compounds with heterocycles, face issues with insufficient light fastness when used for dyeing fabrics, and existing textile printing methods lack excellent washing and perspiration fastness.

Innovation Solution

A compound represented by specific Formulae (1) to (3) is developed, which includes various substituents and a counter anion, enhancing light fastness, washing fastness, and perspiration fastness when used in a coloring composition for ink jet textile printing, allowing for improved dyeing and printing on fabrics like polyamide.

VSEngineering Contradiction Analysis

1Productivity

If ink jet textile printing is used, then delivery time is reduced and environmental friendliness is improved, but the light fastness of the printed fabric is insufficient

Engineering Contradiction:
Improvedelivery timeVSAvoidlight fastness
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The patent modifies the chemical parameters of the dye used in ink jet printing by incorporating specific heterocyclic structures and substituent groups. These parameter changes enhance the light fastness of the printed fabric while maintaining the efficiency and environmental benefits of the ink jet printing process.
