New cationic or amphoteric polymers (I), having at least one tertiary or quaternary amino function, show a self-adhesive strength (in terms of the maximum tensile strength) of at least 2 Newtons (N) and contain units derived from at least one of six specific classes of cationic or amphoteric ethylenic monomers. New cationic or amphoteric radical polymers (I), having at least one tertiary or quaternary amino function, show a self-adhesive strength of at least 2 N (preferably 2-100N, especially 5-100 N) and comprise one or more types of units derived from monomers of formulae: CH2=C(R1)-CO-X-R2-NR3R4 (a), CH2=C(R1)-CO-X-R2-N+R3R4R5 . A- (b), CH2=C(R1)-CO-X-R2-Cyc+ .A- (c), CH2=C(R6)-(CO)p-(X)q-R7-N+R8R9-R10-Z (d) or CH2=C(R11)-(CO-X)r-Cyc+-R12-Z (e). R1, R11 = H or Me; R2 = 1-30C divalent linear, branched, cycloaliphatic or aromatic hydrocarbyl (optionally containing one or more O, N or P heteroatoms); R3 - R5 = 1-30C linear, branched, cycloaliphatic or aromatic hydrocarbyl (optionally containing one or more O, N or P heteroatoms); X = O or NH; A- = counter-ion, preferably halide, sulfate, phosphate or carboxylate (e.g. acetate); Cyc+ = monocyclic or fused bicyclic, cycloaliphatic or aromatic system containing a tertiary or quaternary amino function and optionally one or more O, N or P heteroatoms; R6 = H or 1-4C alkyl; R8, R9 = H or 1-4C alkyl (optionally substituted by Z); R7, R10 = divalent hydrocarbyl (optionally interrupted by O), preferably (CH2)n; n = 1-4; p, q, r = 0 or 1; Z = COO-, SO3- or PO3H-; or R7 = group forming a 5-7 membered, aromatic or non-aromatic heterocycle together with R8, R9 or X (if X = NH); R12 = 1-4C divalent hydrocarbyl. An Independent claim is included for cosmetic compositions (A) comprising a cosmetic medium containing (I). L'invention concerne des polymères radicalaires cationiques ou amphotères, comprenant un ou plusieurs motifs dérivés de monomères éthyléniques, cationiques ou ampholytiques, comportant au moins une fonction amine tertiaire ou quaternaire, caractérisés par le fait qu'ils présentent une auto-adhésivité - exprimée par la force de traction maximale (Fmax (en N)) enregistrée lors du décollement par traction de deux surfaces circulaires de 0,95 cm , enduites de polymère - supérieure ou égale à 2 N, ainsi que leur utilisation en cosmétique, en particulier dans le domaine du coiffage.
