Abstract
1467638 Trinuclear cyanine dyes MINNESOTA MINING & MFG CO 3 June 1974 [1 June 1973] 26402/73 Addition to 1325312 Heading C4P [Also in Division G2] A merocyanine dye of the general formula in which at least one of R, R<SP>1</SP> and R<SP>4</SP>, and R<SP>5</SP> when present, is an alkenyl group, with the exception of the case where both R<SP>4</SP> and R<SP>5</SP> are alkenyl, Z is -CO-N(R<SP>5</SP>)- and both of R and R<SP>1</SP> are not alkenyl; and in which k and I are each 0 or 1 and when k is 0, I is 1 and when k is 1, l is 0. Q is -S-, -Se-, -CH=CH-, -O-, -N(R<SP>6</SP>)- or -C(Me) 2 -, where R<SP>6</SP> is alkyl of 1-4 C which may carry an ester substituent and Me is methyl; m and n are each 0 or 1, R if not alkenyl is alkyl, hydroxyalkyl, carboxyalkyl or sulphoalkyl; R<SP>1</SP> if not alkenyl is aryl, aralkyl or any of the groups given for R; R<SP>2</SP> and R<SP>3</SP> are each H or alkyl of 1-4 C; X and Y are each H, halogen, alkyl of 1-4 C, alkoxy, aryl, amino or acylamino, or X and Y together are methylene dioxy or form a fused-on carbocyclic ring; Z is -S-, -O-, -N(R<SP>5</SP>)- or -CO-N(R<SP>5</SP>)- and R<SP>4</SP>, and R<SP>5</SP> if present, are each, when not alkenyl, H or any of the groups given for R<SP>1</SP>, are prepared by heating a merocyanine of the formula with a quaternising agent, and condensing the quaternary derivative with a compound of the formula
