Abstract: A preparation of an aqueous composition that is resistant to temperature variations may include the use of at least one specific heat-stabilizing agent. The heat stabilization of the viscosity of the aqueous composition within a wide temperature range. Such heat-stabilizing agents may include, in polymerized form: (a1) an anionic monomer comprising a polymerizable olefinic unsaturation and a carboxylic acid group, optionally in salt form; (a2) a C1-C7 ester of acrylic acid, methacrylic acid, maleic acid, and/or itaconic acid; (a3) an associative monomer of a formula, R1-(EO)m-(PO)n-R2, wherein m and n are independently 0 or an integer or decimal less than 150, m or n being different from 0, EO is independently a CH2CH2O group, PO is independently a combination of (i) CH2CH2O and (ii) CH(CH3)CH2O and/or CH2CH(CH3)O, R1 is independently a group comprising a polymerizable olefinic unsaturation, and R2 is independently a straight C28-C40-alkyl group or a C28-C40-alkyl group.

Abstract: The invention relates to the field of marking hard surface substrates, in particular to the field of traffic paints. The invention thus provides an aqueous composition useful for marking hard surface substrates. The composition according to the invention comprises a binder and a pigment that is dispersed with a particular (meth)acrylic polymer. The invention also provides a method for preparing such a composition as well as a method for marking a hard surface substrate with such a composition.
