    • Encapsulated colorants for waterborne coating compositions are provided as a system and kit with a method for tinting the water borne coating compositions. The encapsulated colorant comprises at least one water dispersible tinting material to be released into the based coating composition upon dissolution of the encapsulating layer to give the coating composition color. The encapsulating layer surrounding the colorant has at least one polymer that is soluble in aqueous medium surrounding the tinting material wherein the layer has a thickness from about 0.5 to about 5 mils and can dissolve to release the dispersible tinting material in an aqueous coating composition having about 25 to about 45 volume percent solids and about 55 to about 75 volume percent water in less than 15 minutes with agitation at a temperature in the range of about 50 to about 110° F. One or more of the encapsulated colorants as a pouch or pouches are contained in a moisture resistant package until ready for dissolution in the coating composition. A plurality of the encapsulating colorants as pouches in moisture resistant packaging comprise a system which along with one or more clear or tint base water borne coating compositions comprise a kit. A method involves placing one or more pouches in a volume of coating composition with stirring or shaking to provide a color to the composition.
    • 提供水性涂料组合物的包封着色剂作为用于着色水性涂料组合物的方法的系统和试剂盒。 包封的着色剂包含至少一种水分散性着色材料,以在溶解包封层以释放涂料组合物的颜色时被释放到基础涂料组合物中。 围绕着色剂的包封层具有至少一种聚合物,其可溶于围绕着色材料的水性介质中,其中该层具有约0.5至约5密耳的厚度并且可以溶解以将该分散性着色材料释放在具有约 25至约45体积%的固体和约55至约75体积%的水,在少于15分钟内,在约50至约110°F的温度下搅拌。一种或多种包封的着色剂作为袋或袋 包含在防潮包装中,直到准备好溶解在涂料组合物中。 作为防潮包装袋中的多个包封着色剂包括与一种或多种透明或着色的水性涂层组合物一起包含试剂盒的系统。 一种方法包括将一个或多个袋放置在一定体积的涂料组合物中,同时搅拌或摇动以提供组合物的颜色。
