Claim:
A method of improving the three month gloss level retention of a dry film obtained from applying an alkide resin formulation in an aqueous phase to a surface, said method comprising mixing a dispersing agent and a thickener with water or an aqueous solution or an alkide resin precursor to give the alkide resin formulation in the aqueous phase, wherein: the dispersing agent is a copolymer of (meth)acrylic acid with an oxyalkylated monomer comprising a polymerizable function and terminated by hydrogen or an alkyl group having from 1 to 4 carbon atoms; and the thickener is an associative thickener comprising at least one hydrophobic group selected from the group consisting of a distyrylphenyl, a tristyrylphenyl, a tetrastyrylphenyl, and pentastyrylphenyl.
