Embodiment A-29
[0126]
[0127] 4.75 g of aminopropyl-terminated polydimethylsiloxane ABCR (0.005 mol) was suspended in 15 ml of isopropanol and mixed with 2.67 g of 2-(4-methoxy-phenylazo)-1,3-dimethicone Methyl-3-imidazolium 1-ium (azochromophore A) was mixed. The reaction mixture was heated at 55°C for 24 hours. After cooling the reaction mixture was dried, admixed in 60 ml of chloroform and washed 3 times with 40 ml of water / acetic acid.
[0128] The organic phase was dried again, whereby 6 g of red powder were obtained (yield 81%).

Embodiment A-30
[0132]
[0133] Mix 7.5ml of methylhydrogensiloxane-dimethylsiloxane copolymer [68037-59-2] (name HMS301; MW1900-2000, 25-30mol% SiH, d=0.98; 30mmol-equivalent) in 35ml of toluene A solution in 2.25ml of allylamine (30mmol) and 200μl of platinum (0)-1,3-divinyl-1,1,3,3-tetramethyldisiloxane complex in xylene [68478-92 -2] mix. The reaction mixture was stirred at 55°C for a period of 3 days and then evaporated to dryness, whereby 8.85 g of polymer were obtained.
[0134] NMR in ppm in DCM: 2,5(t,2H); 1,6(br,2H+); 1,4(br,2H); 0,4(t,2H)
Embodiment A-31
[0136]
[0137] 942 mg of polysiloxane A-30 was mixed in 15 ml of isopropanol and mixed with 1.66 g of 2-(4-methoxyphenylazo)-1,3-dimethyl-3-imidazole-1 at 60° C. -onium (azochromophore A) was reacted for 16 hours. After evaporating off the isopropanol in vacuo, the reaction mixture was redissolved in 40 ml DCM (2 minutes in an ultrasonic bath) and 40 ml water (2 minutes in an ultrasonic bath). DCM / water-emulsion was left overnight. The DCM and aqueous phases were separated, the viscous liquid phase remaining, and treated again with DCM and water (same protocol as before). The viscous liquid phase was then admixed in 10 ml of methanol and dried in vacuo (1 mbar), whereby 596 mg of red dye were obtained.
[0138] NMR: 1H in MeOH 7, 8(m, 2H), 7, 4(m, 2H), 6, 7(m, 2H), 3, 9(m, 6H), 3, 2(m, MeOH+2H ), 1, 65(m, 2H), 0(m, 30H)
[0139] Part C: based on polyetherimine
