As for this invention, the positive latex (positive latex) being, the mol % with, a) the monomer unit which of 70% or more and is derived, at least from one cationicity monomer of mol ratio of 99% or less, b), N of the mol ratio which is not zero under 20% (the 2 hydroxyethyl) the monomer unit which is derived from acrylamide, c), formula (i) of the mol ratio which is not zero of 15% or less: AC (=O) O [CH2 ch (R1) O] nR (i)(In formula, n becoming independent, is number 1 - 50, A is the unsaturated aliphatic radical which includes 2 - 6 carbon atoms, R1 the hydrogen atom, the methyl radical or ethyl is radical, R includes 8 - 30 carbon atoms, saturation or the unsaturated direct or the branching aliphatic radical is) the monomer unit which at least is derived from one monomer, d) being optional, 0% super and, description above N of the mol ratio of the 10% or less (the 2 hydroxyethyl) the monomer unit which is derived at least from one neutral monomer other than acrylamide (description aboveMol ratio, N (the 2 hydroxyethyl) is smaller than mol ratio of the monomer unit which is derived from acrylamide truly), and being optional, description above N of the certain ru mol ratio (the 2 hydroxyethyl) monomer unit, and e which are derived at least from one neutral monomer other than acrylamide) being optional, 0% super and, the diethylene or polyethylene building a bridge monomer of mol ratio of 1% or less, depends on polymerization, it includes direct, branching or building a bridge cationicity high polymer electrolyte, it regards the positive latex. This invention regards also the use of the above-mentioned positive latex manner, and the cosmetics constituent or the medical supply constituent which prepare the above-mentioned positive latex as a thickener.< Choice figure >It is not本発明は、陽性ラテックス(positive latex)であって、モル%で、a)70%以上かつ99%以下のモル比の、少なくとも1つのカチオン性モノマーに由来するモノマー単位、b)20%未満のゼロでないモル比の、N-(2-ヒドロキシエチル)アクリルアミドに由来するモノマー単位、c)15%以下のゼロでないモル比の、式(I):A-C(=O)-O-[CH2-CH(R1)-O]n-R・・
