Abstract

The invention relates to agents for temporarily shaping keratin fibers, said agents giving a very high degree of hold without impairing its flexibility and humidity resistance. The agents according to the invention contain, in a cosmetically acceptable carrier, a) at least one copolymer A which contains at least one structural entity of formula (I)—wherein R is a C1-C30 alkyl group, a C1-C4 aralkyl group, a C2-C6 alkenyl group or a C2-C6 hydroxyalkyl group and X− is a physiologically acceptable anion, and which contains at least one further structural entity of formula (II)—wherein n is 1, 2 or 3 as the number of methylene entities; b) and at least one acrylate polymer B, which is different from copolymer A, selected from b1) polyacrylic acid and/or b2) copolymers of methacrylic acid with acrylamidopropane sulfonic acid and/or b3) copolymers of acrylic acid with methacrylic acid and acrylic esters and/or b4) copolymers of acrylic acid with methacrylic acid with acrylic esters and methacrylic esters and/or b5) copolymers of acrylic esters with methacrylic acid.
