May I ask what ingredients are white ink

(1) Pigment
Plays a role in color pigment inks, it has a direct influence on some of the properties of the ink.
Pigments are insoluble in water and an organic solvent dispersion of a powder of high color, black or white, depending on its source and chemical composition, organic and inorganic pigments into two categories.
 inorganic pigments are non-ferrous metal oxide, or some insoluble metal salts, inorganic pigments inorganic pigments are divided into natural and artificial inorganic pigments, inorganic pigments are natural mineral pigments.
 colored organic pigments are organic compounds, is also divided into two major categories of natural and synthetic. Now commonly used in synthetic organic pigments, organic pigments varieties, colors more complete, better performance than inorganic pigments.
Dye is an organic compound, it is soluble in water, and sometimes is dissolved in an organic solvent, a dye can be prepared from insoluble colored precipitate, called lake pigments, for the manufacture of printing inks.
Requirements for pigment printing ink used is high, especially in color, degree of dispersion, light offerings, transparency, color pigments require close spectral color hue, saturation should be as large as possible, the three primary colors of ink used in magenta, cyan, yellow pigment transparency must be high, all the paint only to water, but also to quickly and evenly and binder combination of oil absorption capacity should not be too much pigment, the pigment preferably with alkali, acid, alcohol-resistant potential resistance and other properties.
(2) Binder
Binder is the main component of the ink, the pigment dispersion plays, given appropriate ink stick, fluidity and transfer performance, and after the film formation by the pigment printing fixation of acting on the printed surface. Binder known varnish.
Binder may be made of various materials, such as various dry vegetable oil, most can be used to make the ink binder, mineral oil can also be made of binders, solvents and water, as well as various synthetic resins can be used to make the connection material.
Ink rheology, viscosity, neutral, acid number, color, water resistance and printing performance depends primarily on connections, with a pigment, the use of different binders can be made of different types of ink; and the same kind of binder , using different pigments. Still made the same type of ink, because it does not alter the fundamental properties of the ink, so the ink quality is good or bad, except with the pigment related, mainly depending on the connection material.
(3) packing
The filler is a white, transparent, translucent or discomfort out of the powdered substance. Mainly from the filling, filling pigment part, the appropriate use of these fillers, can reduce the amount of pigment, reduce costs, but also to adjust the properties of the ink, such as dilute thick, mobility, etc., but also increase the flexibility of the formulation design.
(4) Additional materials
Additional material is manufactured in the ink, as well as use in printing, in order to improve performance of the ink itself, while some of the additional material. When formulated according to the basic ink composition, in some characteristics still can not meet the requirements, or due to changes in conditions, and can not meet the requirements of use on the printing, a small amount of auxiliary material must be solved.
There are a lot of additional material, such as: desiccant, anti-desiccant, diluent, withdrawal agents, plasticizers, etc.
If not prolonged exposure is not harmful to the body, is generally recommended not to exceed a year or two for good
