The invention is related to glossy, low- or zero-VOC aqueous paint compositions, comprising water based latex polymer, a hiding pigment, at least one low-VOC coalescence aid having a volatile organic content of less than 50 g/L, and a second inorganic pigment with particle size ranging from about 1 to 100 nanometers. The paint composition gives good block resistance and mechanical strength and can be adopted for paints with at least glossy and semi-gloss finishes.
