Moreover, the present invention relates to an aqueous pigment dispersion for coloring paper making which can be uniformly colored.

。``Problems to be solved by conventional technology and development'' Dyes and pigments have traditionally been used to color paper, but dyes are water-soluble and have an affinity for pulp fibers. Although it can be easily used by simply dissolving it in water in advance, it has the disadvantage of poor color fastness. On the other hand, in the case of pigments, the color fastness is high, but it is necessary to prepare a stable aqueous dispersion of the pigments in advance. That is, an aqueous pigment dispersion is used in which a pigment is finely dispersed in water using an anionic surfactant, generally a sodium salt of a formalin condensate of naphthalene sulfonic acid, using a dispersing machine.

た。On the other hand, the high molecular weight polymers mentioned above, which are paper strength agents, have a common property of agglomerating pigments, and the aqueous anionic pigment dispersions currently commonly used in the paper industry are an exception. However, strong aggregation occurs with polyacrylamide, starch, cationic starch, pregelatinized starch, polyamide/epichlorohydrin resin, etc. As a result, there were various problems such as decreased density of the obtained colored paper, blurred hue, and when aggregation progressed, speckled paper appeared.

散液である。"Means and effects for solving the problem" Under the current situation, the inventors of the present invention have conducted various studies to improve the dispersion stability of pigments in paper strength enhancers, and have found that alkali-soluble resins and alkali-soluble resins can be used as pigment dispersants. If a nonionic surfactant is used in combination, the dispersion stability of the pigment will be improved even if a paper strength enhancer is used, so it will maintain good dispersibility and settle on the bulb fibers, reducing density and blurring the hue. It was discovered that the following components (A) and (1)

The aqueous pigment dispersion of the present invention prepared in Examples 1 to 8 was prepared using the currently used formalin condensate of naphthalenesulfonic acid prepared in Comparative Examples 1 to 2. Compared to the aqueous pigment dispersion prepared using the cyanine blue pigment dispersion prepared in Examples 1 to 7, a remarkable effect on color development was observed when the paper strength enhancer was used for both acidic paper and neutral paper. The colored paper using the aqueous pigment dispersion had greatly improved sharpness when compared to the colored paper using the aqueous pigment dispersion of Comparative Example 1 when a paper strength enhancer was used.
