一种水性光致变色涂料、指甲油及装饰材料
摘要：
本发明公开了一种水性光致变色涂料、指甲油及装饰材料，该水性光致变色涂料，按重量份数计，包括以下组分：水性聚氨酯丙烯酸酯低聚物30～90份，含环氧基团的单体1～10份，反应型乳化剂0.5～5份，光引发剂0.5～10份，水性光致变色剂0.2～30份，水性润湿分散剂0.5～5份，水性流平剂0.05～5份，去离子水1～20份。本发明的水性光致变色涂料不仅解决了热固化型光致变色涂料固化速度缓慢，效率低的问题，而且解决了UV型光致变色涂料中使用大量溶剂或挥发性单体的问题，适用于各种塑料基材或指甲的涂覆，具有较大的工业化生产效益和良好的应用前景。
摘要（英）：

The invention discloses a waterborne photochromic coating as well as nail polish and a decorative material. The waterborne photochromic coating is prepared from the following components in parts by weight: 30 to 90 parts of a waterborne polyurethane acrylate oligomer, 1 to 10 parts of an epoxy group-containing monomer, 0.5 to 5 parts of a reactive emulsifier, 0.5 to 10 parts of a photoinitiator, 0.2 to 30 parts of a waterborne photochromic agent, 0.5 to 5 parts of a waterborne wetting dispersant, 0.05 to 5 parts of a waterborne flatting agent and 1 to 20 parts of deionized water. The waterborne photochromic coating disclosed by the invention has the advantages that the problems of low curing speed and low efficiency of a heat curable photochromic coating, and the problem that a large amount of solvents or volatile monomers are used in a UV (ultraviolet) photochromic coating are solved; the waterborne photochromic coating is suitable for coating various plastic substrates or nail, and has relatively-high industrial production benefits and a good application prospect.
