    Abstract: Azulene squaric acid dyes containing ester groups, of the formula in which L denotes C1-C12-alkylene which is optionally substituted by phenyl, R denotes C1-C12-alkyl, mono- or polyunsaturated C1-C12-alkenyl, which can be substituted by phenyl, C5-C7-cycloalkyl, C5-C7-cycloalkenyl, optionally substituted phenyl, pyrrolyl, furanyl, thienyl or pyridyl and R , R , R and R independently of one another denote hydrogen or optionally substituted C1-C12-alkyl, with the proviso that if R denotes hydrogen, the ring positions of the substituents CH2-L-O-CO-R and R on one or both azulene rings can also be interchanged with one another within an azulene ring, their intermediates and an optical recording medium which contains the novel dyes.

    Abstract: A process for the continuous production of surface coloration on cellulose fibres in the form of textiles by treating the textiles with an aqueous bath containing at least 5 g/l of condensation products, quaternated with benzyl halides, of precondensates of trialkanol amines and ureas, cyclic carbonates and/or epihalogen hydrines and/or condensation products, quaternated with benzyl chloride, of piperazine and epichlorohydrin and 0.02 to 1 g/l of a phosphoric acid triester, the alcohol component of which has 6 to 18 carbon atoms, dyeing the textile thus treated in a separate bath in an aqueousmedium with reactive dyes, fixing the dye by treatment with an aqueous alkaline bath and completing the dyeing in the usual manner. The individual cellulose fibres of the textile are not completely dyed through but rather exhibit ring coloration.

    Abstract: An optical recording medium comprises a transparent support; a laser-sensitive dye contg. layer; and a reflective layer contg. a silicon-phthalocyanine deriv. of formula (I) in whcih R1 is bounded to the phthalocyanine residue, R1 = H, 1-12 C alkyl, 1-12 C alkoxy, halogen or -Si(R2)(R3)(R4) in which R2, R3 and R4 each = 1-5 C alkyl; n = 1, 2, 3 or 4; and A and B each = 1-12 C alkyl, halogen or -OR5 in which R5 = 1-12 C alkyl which is opt. interrupted by one or more O atoms or 1-14 C alkylimino gps. and/or which is opt. substd. by a 5- or 6-membered satd. heterocyclic residue, or a gp. Si(R2)(R3)(R4) where R2, R3 and R4 are as above.
