Abstract

1330996 Vinyl chloride/vinyl acetate copolymer composition AMERICAN CYANAMID CO 21 Jan 1972 [2 March 1971] 3103/72 Heading C3P [Also in Division G2] A composition used in making optical filters (see Division G2) comprises a copolymer of vinyl chloride (97%) and vinyl acetate (3%); tetrahydrofuran (as solvent); dioctyl phthalate; C.I. Acid Green 25; C.I. Dispese Red 9; C.I. Solvent Yellow 13; C.I. Solvent Yellow 14; Direct Dye C.I. 28705; and either 1,4,5,8- tetracyclohexylaminoanthraquinone or 4-(1- azuleniumylidene)-2-( 1-azulenyl)-3-oxo-1-cyclobutenolate. This composition is coated on to glass and dried to give a light-absorbing layer.
