Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a colored liquid cleaning composition, and more particularly to a colored liquid cleaning composition with improved light resistance. [Prior Art and its Problems] Products are generally colored in order to increase their value or to convey the product's performance.

Liquid cleaning agents are also often colored depending on their use. In this case, it is said that it is preferable to reduce the amount of coloring agent added as much as possible because if the amount of coloring agent added is too large, it may cause problems such as dyeing the clothes. However, if the amount added is small, there is a problem that if the container containing the liquid cleaning agent is transparent, the color will fade during storage, especially when exposed to sunlight. Therefore, in order to prevent this fading, it has been proposed to add an ultraviolet absorber to the container, but the effect is still not sufficient.

[Means for solving problems]

Under these circumstances, the present inventors have conducted extensive studies on colored liquid detergent compositions that use nonionic surfactants as the main detergent base, and have found that a colorant having a sulfonic acid group and a cationic group or tertiary group The inventors discovered that the above problems could be solved by using a polymer latex containing amine groups, and completed the present invention.

(hereinafter abbreviated as "nitrogen-containing monomer") or other water-insoluble polymerizable monomers in a microemulsion or solubilized state. This microemulsion state can be achieved by selecting an appropriate temperature near the phase inversion temperature using a nonionic surfactant, or by adding an anionic surfactant to an appropriate co-surfactant such as a higher alcohol or a nonionic surfactant. This can be achieved by combining it with Further, the solubilized state can be achieved by using a large amount of surfactant relative to the polymerizable monomer.

The most preferable method for producing nitrogen-containing polymer latex is to prepare an aqueous solution by adding a surfactant to a reaction vessel filled with water, and then heating this at a temperature close to the phase inversion of the surfactant micelles.

[Effect]

In general, dyeings have poor light fastness, and when a nonionic surfactant is contained, the light fastness of the dyeing in a dilute solution or dispersed state is reduced. However, in the present invention, the reason why the light fastness of dyeing is improved by adding nitrogen-containing polymer latex is not clear, but the cationic groups in the latex and the sulfonic acid groups in the dye bond, and the dye It is thought that this is due to the fact that it is adsorbed onto the latex.
