Description
Technical area
The present invention relates to as coating, printing ink, plastic cement with tinting material, printing and dyeing, color toner and other colorants with the manufacture method of the processed pigment composition of the adaptability excellence of raw material and the processed pigment composition that obtains by this manufacture method.
Background technology
Usually, when using pigment as the colorant of various industry goods, materials and equipments, the normal wet cake pigment that contains moisture that uses is used in printing ink, plastic cement with fields such as tinting materials.Wet cake pigment is, such as Japan's special permission disclose 7-188575 number, Japan's special permission disclose in 8-60068 number record, general method be employing contain molecular weight be tens thousand of to about 100,000 resin and the varnish treated of solvent become processed pigment.
Summary of the invention
As the pigment of colorant, wish that it has not aggegation minuteness particle and the characteristic of stable and processing ease.For solving this problem, proposed a kind of pigment and wrapped up processing with dispersion stabilizers such as resins to fine dispersion state, suppress mutual agglutinative processed pigment between the pigment.
Yet, when the aqueous suspension thing of wet cake pigment being carried out the phase inversion processing mutually from the water to the resin with common resin, for improving flowability and phase inversion efficient, indispensable ground will add solvent in resin, may cause to handle the back to the necessity of solid constituent management or the solvent flashing problems such as influence to operating environment.
And, handle the back if solvent flashing component fully, problem such as needs are long-time in the time of also can existing printing inkization etc. to be dissolved in the solvent again.
And then, during with the solvent individual curing and with the high plastic resin treatment of solvent containing ratio, can produce the pigment phase inversion and be resin and cause problems such as crystalline growth after mutually.
The present invention carries out in view of these problems, provide and use than be the quantity of solvent of lower concentration, preferably solvent-free in the past, just can be the crystallization-stable height of pigment after and the manufacture method of the good processed pigment composition of dried solvability more effectively from the water phase inversion to resin phase, phase inversion, and the processed pigment composition that uses this manufacture method.

(phase inversion)
As shown in table 1, the phase inversion time of processed pigment 1,2,3,4,5,6 can obtain good phase inversion within 10 minutes.On the other hand, through the processed pigment 7 of the high plastic resin treatment of molecular weight, to 30 minutes time of phase inversion needs.
(solvability)
As shown in table 2, the dispersity value of processed pigment 1,2,3,4,5,6 can obtain being judged as the value smaller or equal to 7.5 μ m of favorable dispersity, its favorable solubility as can be known.On the other hand, can be observed particle about several mm by range estimation through the dispersity value of the processed pigment 7 of the high plastic resin treatment of molecular weight, and be not dissolved in the binder resin solution fully.
(form and aspect evaluation)
As shown in table 3, the processed pigment 1,4,5,6 that uses identical wet cake pigment is compared, only there is processed pigment 6 to become opaque form and aspect because of L value height as transparent benchmark.About the reason of opacification, known is because of due to the crystalline growth of pigment, thus think processed pigment 6 in processing and the lower molecular weight good solvent after handling be to have promoted crystalline growth under the toluene environment.In addition, processed pigment 7 is owing to inhomogeneous the failing of filming of making measured.
According to the present invention, by using the non-water-soluble resin that has a mobile oligopolymer zone at normal temperature to handle the aqueous suspension thing of pigment dyestuff, can provide that the phase inversion of pigment from water to the resin phase is good, the crystallization-stable height behind the phase inversion and dry back be to the processed pigment composition and the manufacture method thereof of the excellence of solvability again of adhesive resin etc.
Relevant industries personnel can know, are preferred embodiment of the present invention as mentioned above, can carry out many changes and correction under the situation of not violating the spirit and scope of the present invention.
