| titleOfInvention | Improved aqueous compositions for whitening and shading in coating applications |
| abstract | The instant invention relates to the Aqueous coating compositions for optical brightening and shading of substrates, comprising n(a) at least one optical brightener of formula (I)n nin which nthe anionic charge on the brightener is balanced by a cationic charge composed of one or more identical or different cations selected from the group consisting of hydrogen, an alkali metal cation, alkaline earth metal, ammonium, ammonium which is mono-, di-, tri- or tetrasubstituted by a C 1 -C 4 linear or branched alkyl radical, ammonium which is mono-, di-, tri- or tetrasubstituted by a C 1 -C 4 linear or branched hydroxyalkyl radical, ammonium which is, di-, tri- or tetrasubstituted by a mixture of C 1 -C 4 linear or branched alkylradical and linear or branched hydroxyalkyl radical or mixtures of said compounds, nR 1 and R 1 ' nmay be the same or different, and each is hydrogen, C 1 -C 4 linear or branched alkyl, C 2 -C 4 linear or branched hydroxyalkyl, CH 2 CO 2 - , CH 2 CH 2 CONH 2 or CH 2 CH 2 CN, nR 2 and R 2 ' nmay be the same or different, and each is C 1 -C 4 linear or branched alkyl, C 2 -C 4 linear or branched hydroxyalkyl, CH 2 CO 2 - , CH(CO 2 - )CH 2 CO 2 - , CH(CO 2 - )CH 2 CH 2 CO 2 - , CH 2 CH 2 SO 3 - , CH 2 CH 2 CO 2 - , CH 2 CH(CH 3 )CO 2 - , benzyl, or nR 1 and R 2 nand/or R 1 ' and R 2 ' , together with the neighboring nitrogen atom signify a morpholine ring and np nis 1 or 2, n n(b) at least one shading dye of formula (II)n nin which nR 3 nsignifies H, methyl or ethyl, nR 4 nsignifies paramethoxyphenyl, methyl or ethyl, nM nsignifies a cation selected from the group consisting of hydrogen, an alkali metal cation, alkaline earth metal, ammonium, ammonium which is mono-, di-, tri- or tetrasubstituted by a C 1 -C 4 linear or branched alkyl radical, ammonium which is mono-, di-, tri- or tetrasubstituted by a C 1 -C 4 linear or branched hydroxyalkyl radical, ammonium which is, di-, tri- or tetrasubstituted by a mixture of C 1 -C 4 linear or branched alkylradical and linear or branched hydroxyalkyl radical or mixtures of said compounds, n n(c) at least one white pigment, n(d) at least one primary binder, n(e) optionally one or more secondary binders and and n(f) water. |
