In-situ Polymerization for Preparation of Encapsulated Light-Fast Yellow G Pigment

This article has described the features and technology of melamine encapsulated light-fast yellow G pigment for improvement of its heat stability. It has discussed influence of emulsification and dispersant, mol ratio of melamine and formaldehyde, encapsulating melamine amount, and pH value on the properties of product. The optimal technology conditions were given. The pigment was characterized with differential thermal analysis (DTA) and scanning electron microscope (SEM).
