A shade enhancing agent comprises an aqueous resin emulsion composition obtained by polymerizing a monomer in the presence of a cationic surfactant or a cationic protective colloid, polymerizing a monomer and adding a cationic protective colloid or polymerizing a monomer in the presence of a cationic or nonionic emulsifying dispersant so as to have a cationic group in the molecule, a dry film of said composition having a glass transition point (Tg) in the range between 20°c and 110°c and a refractive index of 1.50 or less, said emulsion composition having a zeta potential in the range between +5 and +80 mV at an ion strength of 10-3 and a pH value of 7.
一种遮光剂包括一种水性树脂乳液组合物,该组合物通过在阳离子表面活性剂或阳离子保护胶体存在下聚合单体、聚合单体并添加阳离子保护胶体或在阳离子或非离子乳化分散剂存在下聚合单体以使分子中含有阳离子基团而获得,所述组合物的干膜的玻璃化转变点(Tg)在 20°C 至 110°C 之间,折射率为 1.50 或更低,所述乳液组合物在离子强度为 10-3 和 pH 值为 7 时的 zeta 电位在 +5 至 +80 mV 之间。
