FIELD: dyes, building materials.

SUBSTANCE: invention relates to sets of dye semifinished products used in preparing dyes of different designation. Invention describes the dye semifinished product with properties of fluidity and covering power that can be used in preparing a single-package latex dye stained with pigment wherein the volume content of dry matter is from about 30% to about 70% with the Schtormer viscosity value from about 50 to about 250 EK and comprising the following components: (I) at least one pigment conferring the covering power property; (II) at least one dispersing agent; (III) at least one thickening agent, and (IV) water wherein at least one dispersing agent and at least one thickening agent are compatible with at least one pigment and other dye components. Also, invention describes sets for dyes and dye lines comprising a latex polymeric binding agent. Some dyes for internal and external coating of different objects are prepared by using sets of dye semifinished products. Invention provides preparing the broad assortment of dyes of different quality for external and internal workings and with different levels of polishes and bases for carrying out the coloring from dye semifinished products and by using the minimal amount and types of the dye components. Proposed dye semifinished products can be used for architecture, industrial, polygraphic, elastomeric and non-cement coatings.

EFFECT: improved preparing method, valuable properties of dyes.
