Problems solved by technology

Nevertheless, some inherent problems still restrain the growth of multicolor paint.
Prior art based on ionic interactions, where the cross-linker includes ions of calcium, aluminum, zinc and boron, have the potential to hurt the stability of acrylic polymer binders, resulting in the loss of final coating performance properties.
Dissolving these high molecular weight natural polymers takes a significant amount of time and usually requires heating.
Hydrogels based on these natural polymers are biodegradable, which can lead to stability issues.
Mixing different gels and cross-linkers can also cause production issues.
They cannot be applied by brush or trowel due to the following reasons: a) the colored granules tend to be broken by shearing force; b) the hard, gelatinous or brittle globules give low surface drag and tend to skid on smoot

Example

[0082]The coatings prepared using the compositions of Examples 13, 14 and 15 are smooth after drying, which shows that the compositions are useful for the preparation of interior wall decorative coatings.

[0083]Coatings with silky, silky-flaky and flaky patterns can be obtained by tuning or adjusting the texture of the gel used to prepare multicolor paints. These patterns are rarely seen in the current market.

[0084]The MCPs of Examples 11, 16 and 17 are used to evaluate the compatibility of colored strong gels with the binders PRIMAL™ AC261p (pure acrylic emulsion), PRIMAL™ SF155 (styrene-acrylic emulsion) and Impranil® DL1380 (polyurethane dispersion). The appearance of paints prepared using each binder / gel combination are shown in FIGS. 4a through 4c, which show the coatings of Examples 11, 16 and 17, respectively. It can be seen that in these formulations colored gels of the invention are provided good colorant and shape protection no matter which binder is used, and that good mult
