Fluid concentrates, colorants and coating compositions contain solid pigment particles dispersed in a nonvolatilizing, reactive liquid diluent having a viscosity less than 1,000 cps and containing at least one molecular species having at least three reactive unsaturated sites. The reactive liquid diluent may serve as one or more of a dispersing medium for the solid pigment particles, a carrier, a coalescent and a humectant, and may crosslink or otherwise cure to form an interpenetrating polymer network in, or crosslink with, a pigmented coating composition containing a film-forming polymeric binder. Embodiments of the reactive liquid diluent can provide colorants and coating compositions having reduced levels of VOCs, conventional carriers, conventional dispersants, conventional coalescents and conventional humectants.
浓缩液、着色剂和涂料组合物含有分散在非挥发性反应性液体稀释剂中的固体颜料颗粒,该稀释剂的粘度小于 1,000 cps,并含有至少一种具有至少三个反应性不饱和位点的分子种类。反应性液体稀释剂可用作固体颜料颗粒的分散介质、载体、凝聚剂和保湿剂中的一种或多种,并可交联或以其他方式固化,从而在含有成膜聚合物粘合剂的颜料涂料组合物中形成互穿聚合物网络,或与之交联。反应性液体稀释剂的实施方案可提供具有较低挥发性有机化合物含量的着色剂和涂料组合物、传统载体、传统分散剂、传统凝聚剂和传统保湿剂。
