  2. methyl methacrylate, ethyl acrylate, methacrylic acid, butanoic acid 3-oxo-2-[(2-methyl-1-oxo-2-propenyl)oxy]ethyl ester, 3-(trimethoxysilyl)propyl methacrylate with poly(oxy-1,2-ethanediyl), alpha-sulfo-omega-[4-nonyl-2-(1-propen-1-yl)phenoxy]-, branched, ammonium salts copolymer; and
  3. 1,3-benzenedicarboxylic acid, polymer with 2-[(2-aminoethyl)amino]ethanol, 1,3-bis(isocyanatomethyl)cyclohexane, decanedioic acid, 1,3-diisocyanatomethylbenzene, 2,2-dimethyl-1,3-propanediol, 1,2-ethanediol and 3-hydroxy-2-(hydroxymethyl)-2- methylpropanoic acid, compound with 1,1',1''-nitrilotris[2-propanol] (CAS Reg. No. 1239020-50-8).
