| abstract | The invention relates to dyes of the formulae <FORM:1112035/C4-C5/1> <FORM:1112035/C4-C5/2> <FORM:1112035/C4-C5/3> wherein R and R2 are alkyl or substituted alkyl, Z and Z1 complete heterocyclic nuclei, j = 0 or 1, R1 is hydrogen, alkyl or aryl, n = 0, 1, 2 or 3, Y and Y1 in Formula III when Y2 is absent is a group of the formulae <FORM:1112035/C4-C5/4> <FORM:1112035/C4-C5/5> at least one of Y1 and Y2 is a group as defined for Y and, when only one of Y1 and Y2 is such a group, the other represents hydrogen, alkyl, substituted alkyl or aryl, q = 2, 3 or 4, R3, R4 and R5 are alkyl, W and W1 are O, S, Se or <FORM:1112035/C4-C5/6> wherein R8 is alkyl or aryl, p = 0 or 1, Q is -S-CD-, -O-CD-, -NY2-CD- or -CO-NY2-CD1-, D is O or S and D1 is O, S or Se. The dyes of Formula I are obtained by quaternizing an appropriately substituted 2-thionomerocyanine dye with an appropriately substituted methyl-substituted quaternary salt. Reaction of the aforesaid merocyanine dye quaternary salts with compounds of the formula <FORM:1112035/C4-C5/7> gives dyes of the Formula II. Dyes of Formula III are obtained by condensing a compound of formula <FORM:1112035/C4-C5/8> with an appropriately substituted hydrocarbyl thio-substituted quaternary salt. 3-(3-Dimethylamino propyl) - 5 - {(1 - methyl - naphtho [1,2 - d] thiazolin - 2 - ylidene) - 1 - phenyl ethylidene} rhodanine hydroperchlorate is prepared from 2 - (1 - chlorostyry) - 1 - methyl - naphtho (1,2 - d) thiazolium chloride and 3 - (3 - dimethylamino propyl) rhodanine hydroperchlorate in alkaline medium which is subsequently acidified with HCl/NaClO4. 3-(3 - Diethylamino propyl) - 5 - {(1 - ethyl naphtho [1,2-d] thiazolin-2-ylidene)-1-phenyl ethylidene} rhodanine hydroperchlorate is prepared from 1 - ethyl - 2 - (1 - ethylthiostyryl) naphtho [1,2-d] thiazolium ethylsulphate and 3 - (3 - dimethylamino propyl) rhodanine hydroperchlorate. 1 - (2 - Diethylaminoethyl)-5 - {(1 - ethylnaphtho [1,2 - d] thiazolin - 2-ylidene) isopropylidene} - 3 - phenyl - 2 - thio barbituric acid is prepared from 1-(2-diethylamino ethyl) - 3 - phenyl - 2 - thiobarbituric acid hydroperchlorate and 1 - ethyl - 2 - methyl-naphtho (1,2-d) thiazolium p-toluene sulphonate. The corresponding 3-phenyl barbituric acid is obtained similarly.ALSO:3 - (3 - Diethylaminopropyl) - rhodanine hydroperchlorate is prepared by reacting bis (carboxymethyl)trithiocarbonate in alkaline solution with N,N - diethyl - 1,3 - propanediamine, making the solution acid with HCl and adding sodium perchlorate. In a similar manner 3 - (3 - dimethylaminopropyl) rhodanine hydroperchlorate and 3-(2-dimethylaminoethyl)rhodanine hydroperchlorate can be prepared. 1-(2-diethylaminoethyl)-3-phenyl-2-thiobarbituric acid hydroperchlorate is prepared by reacting phenyl isothiocyanate with N,N-diethylethylenediamine in HCl to give 1-(2-diethylaminoethyl)-3-phenyl-2-thiourea hydrochloride and reacting the latter with malonyl dichloride and sodium perchlorate. 1-(2-diethylaminoethyl)-3 -phenylbarbituric acid hydroperchlorate is prepared similarly. |
