This paper studies the experimental method that uses the liquid phase method to prepare cobalt blue mica coated titania pearlescent pigment with urea as precipitant. The optimum technology parameters and the chemical composition of resulting pigment are introduced. The coating principle of cobalt...
A new class of squarylium homologue, namely, an electronically neutral methine-bridged bisquarylium dye, was synthesized by a reaction of 4-(4- N , N -dialkylaminophenyl)-3-hydroxy-3-cyclobutene-1,2-dione with an excess amount of triethyl orthoformate. The X-ray crystallographic analysis revealed...
This study investigated the possible efficient photo-induced interaction of hydrophobic and hydrophilic dyes that were separated by several special micro-environments. The three coumarin dyes as hydrophobic dyes and Rose Bengal B Na + salt (RB) as a hydrophilic dye were chosen as the energy donor...
