摘要：
The present invention relates to composition comprising a) first polymer particles that are functionalized with structural units of a TiO2-adsorbing monomer, and second polymer particles that are functionalized with structural units of diacetone acrylamide; and b) a dihydrazide or a diamine crosslinking agent, based on the weight of the composition. Coatings prepared from the composition of the present invention shows improved hardness and gloss.
