AQUEOUS DISPERSIONS CONTAINING AT LEAST ONE ALKYD RESIN AND AT LEAST ONE POLYMERISATE HAVING AT LEAST ONE (METH)ACRYLATE SEGMENT Russian patent published in 2013 - IPC C09D133/06 C09D167/08 

Abstract RU 2478677 C2

FIELD: chemistry.

SUBSTANCE: present invention relates to making coatings from aqueous dispersions and an aqueous dispersion containing at least one alkyd resin and at least one polymerisate having at least one (meth)acrylate segment. The (meth)acrylate segment contains 1-30 wt % of structural units derived from (meth)acrylates which in the alkyl residue have at least one double bond and 8-40 carbon atoms, 0.1-10 wt % of structural units derived from monomers containing acid groups, and 50-98.9 wt % of structural units derived from (meth)acrylates having 1-6 carbon atoms in the alkyl residue, based on the weight of the (meth)acrylate segment.

EFFECT: invention enables to obtain dispersions with prolonged storage stability and coatings with high mechanical strength.
