1,146,522. Polymers containing fluorescent compounds. EASTMAN KODAK CO. 3 May, 1966 [3 May, 1965], No. 19498/66. Heading C3P. [Also in Divisions C4 and G2] Styrene is polymerized in aqueous emulsion containing alkylphenoxypolyethoxyethyl sulphate surfactant and potassium persulphate initiator, and in the presence of a mixture of two fluorescent compounds, viz. 1,1,4,4-tetraphenylbutadiene and 1,4-bis-2-(5-phenyloxazolyl)-benzene. Š mixture of butyl acrylate and styrene is polymerized in an aqueous medium containing succinylated glue, potassium persulphate, a lauryl sulphate surfactant and a fluorescent compound, viz. 3-phenyl-7-ureido-coumarin. The above polymer latexes are used for forming fluorescent coatings (see Division C4).
