1,4-Bis(cyano styryl) mixts. for optical brighteners - esp. for natural or (semi)synthetic high molecular organic material partic. polyester fibres
1,4-Bis(cyano styryl) mixts. for optical brighteners - esp. for natural or (semi)synthetic high molecular organic material partic. polyester fibres
Mixt. of at least three different cpd.s of formula (I) contains 30-90 wt% o,p-ionomers or 20-90 wt%, m,p-isomers are two other symmetrically and/or asymmetrically, substd. ionomers, p,p'-ionomers. Also claimed is the prepn. of the mixt. contg. below 5-50 wt% o,o'-, o,p'= and o,m'-ionomers of (I) by reacting terephthaldialdehyde (TPADA) with cpds. of formulae (II), (III) and (IV). Q = -CH2P(O)(OR2), -CH2-P(O)R(OR), -CH2-P(O)-R2 or -CH2-P+R3X; R = opt. substd. 1-6(1-4)C alkyl or aryl; and X = Cl or Br. 1 mol. equiv. TPADA is reacted with 1.05-1.5 and equiv. (II) then 0.05-0.5 (0.005-0.7) mol. equiv. (III) and 0.45-0.9 (0.25-0.7) mol. equiv. (IV). USE/ADVANTAGE - Used as optical brightness in natural or (semi)synthetic high monomer organic materials, partic. polyester fibres (claimed), as well as granulates, foams, fibre e.g. for use in textile webs, paper etc., coatings, etc.. Whitener is good and icd nuauces can be observed. Further uses include scintillators for e.g. electrophotography, spin-bath prepn. in the mfr. of e.g. wash-and-wear clothing and in mixts. contg. pigments for printing dyebaths.
