Water coating colors

Colorants must be introduced into the coating syrups during production of pan-coated candies. Water-soluble colorants may be used but lake pigments as dispersions are preferred. Pan-coated candies require higher concentrations of colorants than jellies or creams they require 30 to 60 coatings of colored syrup. ... 

Methods based on the observation of a sudden change in properties in a series of PVCs (e.g., ion permeability, permeability to water vapor, color, gloss stability after coating with a silk-luster paint)... 

Microbiological action in starch dispersions results in a drop in pH, loss of viscosity and the development of odor. Retrogradation may be accelerated by the drop in pH or especially if butanol, which complexes with amylose, is generated via starch fermentation. Sulfate-reducing bacteria will cause black deposits due to reaction with iron in the process water. For quality control, preservatives are added to starch slurry, cooked starch, surface size and coating color. 

VIKON FGT forms a clear, continuous film of high resistance to abrasion on fabrics and can be used for coating colored yarn fabrics for slip-covers, etc. It is also an excellent latex for making water based paints for painting awnings, tarpaulins, etc. The coating formed has high resistance to submersion under water. 

For surface coloration, which includes coated tablets, the choice of color is usually restricted to insoluble pigments. The reasons for this include their lack of color migration, greater opacity, and enhanced color stability over water-soluble colors. ... 

Lakes are frequently used in coloring tablet coatings since, for this purpose, they have the general advantages of pigments over water-soluble colors. See Table V. 

Starch phosphate was combined with rosin and alum to increase the dry strength and ink retention characteristics of paper.1677 Starch phosphates have also been used as soil conditioners to increase water retention.1678 Starch phosphates improved the dispersion and dye reception of synthetic fibers,1667 and are used to stabilize water,1543 finger paints,1679 and white coating colors.1680 Phosphonoamidated starches are useful in paper sizing.1681 Biodegradable films were produced by combining starch phosphate with poly (vinyl alcohol).1682 Phosphonoacetyl starch added to polyacrylonitrile improved it affinity for dyes.1683... 

In conventional exterior-use paints SB dispersions have largely been replaced by styrene-acrylate dispersions, and their use is now restricted to special applications (corrosion protection primers, wood primers, mortar modification) where low film permeability to gases, water vapor, etc., and complete resistance of the polymer to hydrolysis are necessary. In order to achieve a uniform surface and thus improve printability, paper and card are coated with paper-coating colors. Carboxylated SB dispersions are used in these paints as binders.
