The present invention relates to hair care compositions which contain a polymer which is prepared from N-vinyl acetamide (NVAM) monomer and the use of those hair care compositions to treat hair. The polymer may be a homopolymer of NVAM or an interpolymer of NVAM and at least one vinyl monomer. The polymer is present in amounts effective to provide the hair care compositions with hair fixative properties and/or hair conditioning properties.

Hair care compositions containing polymeric N-vinyl acetamide and methods of treating hair

Emulsion type rust-preventive baking composition which comprises a polymer emulsion such as an aqueous acrylic resin emulsion and a heat-fusible organic filler having a melting or softening point within the range of 40.degree.-250.degree. C. which is higher by at least 10.degree. C. than the lowest film-forming temperature of the polymer emulsion, as incorporated in the polymer emulsion. When the emulsion type rust-preventive baking composition obtained by the mixture is coated on reinforcing steel rods or the like treatment targests and baked, the heat-fusible organic filler melts and fills pores in the rust-preventive coat film, whereby the coat film is rendered close and compact to produce excellent rust-preventive effect.
