POLYMERIC HAIR DYES

摘要

Disclosed are polymeric dyes of formula (1a); (1b); or (1c); wherein A and B, independently from each other represent a polymer backbone; X<SUB>1</SUB> and X<SUB>2</SUB> independently from each other are a linkage group selected from -C<SUB>1</SUB>-C<SUB>10</SUB>alkylene-; -C<SUB>2</SUB>-C<SUB>12</SUB>alkenylene-; -C<SUB>5</SUB>-C<SUB>10</SUB>cycloalkylene-; C<SUB>5</SUB>-C<SUB>10</SUB>arylene; -C<SUB>5</SUB>-C<SUB>10</SUB>arylene-(C<SUB>1</SUB>-C<SUB>10</SUB>alkylene)-; -C(O)-; -(CH<SUB>2</SUB>CH<SUB>2</SUB>-O)<SUB>1-5</SUB>-; -C(O)O-; -OCO-; -N(R<SUB>1</SUB>)-; -CON(R<SUB>1</SUB>)-; -(R<SUB>1</SUB>)NC(O)-; -0-; -S-; -S(O)-; -S(O)<SUB>2</SUB>-; -S(O)<SUB>2</SUB>-N(R<SUB>1</SUB>R<SUB>2</SUB>); or the direct bond; R<SUB>1</SUB> and R<SUB>2</SUB> independently from each other are hydrogen; or unsubstituted or substituted, straight-chain or branched, monocyclic or polycyclic, interrupted or uninterrupted C<SUB>1</SUB>- C<SUB>14</SUB>alkyl; C<SUB>2</SUB>-C<SUB>14</SUB>alkenyl; C<SUB>6</SUB>-C<SUB>10</SUB>aryl; C<SUB>6</SUB>-C<SUB>10</SUB>aryl-C<SUB>1</SUB>-C<SUB>10</SUB>alkyl; or C<SUB>5</SUB>-C<SUB>10</SUB>alky(C<SUB>5</SUB>-C<SUB>10</SUB>aryl); Y<SUB>1</SUB> and Y<SUB>2</SUB> independently from each other are a residue of an organic dye; or hydrogen; wherein at least one of Y<SUB>1</SUB> and Y<SUB>2</SUB> is a residue of an organic dye; An<SUB>1</SUB>, An<SUB>2</SUB> and An<SUB>3</SUB>, independently from each other are an anion; a and b independently from each other are a number from 1 to 3; m is a number from O to 1000; n is a number from O to 1000; and p is a number from 1 to 1000; wherein the sum of m + n + p = 3.
