The technical FIELD
The present invention relates to a paste resin for universal pigment paste for kolorowania color paints.
The LEVEL of TECHNOLOGY
In the paint and coatings industry, raw material control and procurement carried out through the use of systems of color mixing. In such systems, paint color selected by the user, is obtained by selecting a base paint from a number of available base colors and add to the selected base paint one or more pigment pastes, which are homogeneous mixtures of one or more pigments with paste resins, the latter have good dispersing properties. Such systems are widely used in the field of decorative coatings, as disclosed, for example, in the publication EP 0311209 A1.
Examples of pigment paste for tinting paints disclosed in the publications WO 91/06607 A1 (polyesters, water-based), WO 99/49963 A1 (polyether oil-based) and EP 0458479 A2 (modified acrylic polyol for paints oil-based). In addition, at least one pigment pigment pastes typically include special resins, solvents and also, typically, additives. Pigments for different colors vary in their chemical nature from simple inorganic elements,such as carbon in the form of a gas channel carbon black or lamp black, to inorganic oxides (such as iron oxide, pigments based on copper, cobalt, chromium and lead) and organic pigments (such as azo pigments, phthalocyanine pigments and polycyclic aromatic pigments such as Pereladova, antrahinonove and chinaredorbit pigments). For each pigment, you must use a compatible resin. This resin, in turn, must be compatible with the binder system of basic paints and resins used in other pigment pastes, because most of the colors you want to add more than one pigment paste. The resin must also be capable of dispersing a sufficient amount of pigment. Up to now, no you can't use system kolorowania compatible with paints oil-based and water-based paints, and which is also compatible with the usual assortment of binder resins.

From this table it can be seen that the pigment paste made using a paste resin in accordance with the present invention, yielded positive results in combination with white water-based paint, which is comparable to results obtained with a commercial pigment paste is water-based; whereas commercial pigment paste oil-based in combination with the same water-based paint has less Shine and color intensity.
On the other hand, pigment paste, made using a paste resin in accordance with the present invention, with positive results in combination with the white paint is oil-based, comparable with the results obtained with a commercial pigment paste oil-based; whereas commercial pigment paste water-based in combination with the same paint oil-based has less Shine and color intensity.
Thus, the paste resin in accordance with the present invention has extremely good compatibility with paints on oil and aq is th basis in both cases shows the performance on a par with the same class of commercially available pigment pastes of modern technology without compromise for universal compatibility. Similar results were obtained when pigmented inks are prepared based on acrylic binders paints water-based and oil-based. Thus, for the compilation of paint is sufficient to prepare only one colorous pasta-based paste resin in accordance with the present invention for use with alkyd paints, water-or oil-based, as well as for use with acrylic paints, water-or oil-based, which eliminates the need to stock different pigment pastes for each of these binders in the paint.
Also found that the pigment paste prepared with paste resins in accordance with the present invention can be used in the case of hybrid resins based accelerandi alkyd resins, as well as in the case Ratanakiri and urethaneacrylate resins as binders paints, and also in combination with inorganic and organic pigment materials mentioned earlier.
