Described is a thermoplastic resin film having on a surface thereof a hydroxy-modified imine polymer containing repeating units represented by the following general formula (I) in an amount of 5 mol % or more based on the total of repeating units. This thermoplastic resin film has ink transfer, adhesion and aging stability, and excellent printability of generating no back ghost when offset printing using oxidation polymerization type ink is performed on both faces

Thermoplastic resin film satisfactory in printability

A hair cosmetic composition having an excellent hair setting property, and which imparts to hair good flexibility and a good finish feeling. The hair cosmetic composition comprises (a) a water-soluble amine-oxide-containing polymer having a weight-average molecular weight of 10,000 to 500,000 and (b) a water-soluble polymer selected from the group consisting of nonionic, cationic, anionic and amphoteric polymers. The weight ratio of component (a) to component (b) falls within a range of from 1:10 to 10:1. Components (a) and (b) are incorporated in a total amount of from 0.1 to 10 wt. % based on the hair cosmetic composition.

Hair cosmetic composition containing amine-oxide polymer

The present invention discloses an aqueous resin composition containing (A) a copolymer of (a) a monomer having one or more aldehyde groups or ketone groups, and a radical polymerizable unsaturated bond, in a molecule, with (b) a monomer having a radical polymerizable unsaturated bond copolymerizable with the monomer (a); (B) a hydrazine compound of the following formula (1)

Aqueous resin composition

A hair cosmetic composition comprising an amine-oxide-containing water-soluble resin having a weight-average molecular weight of 5,000 to 1,000,000. The hair cosmetic composition of the present invention has excellent setting force, conditioning effects and hair-washing property and being free from stickiness.

Hair cosmetic compositions

A process for producing a powdered carboxyl-containing polymer comprising mixing a solution of a water-insoluble polymer containing a carboxyl group per molecule in a hydrophilic organic solvent (e.g., ethanol) and an aqueous solution of a dispersant comprising a neutralized copolymer of a carboxyl-containing unsaturated monomer and a (meth)acrylic ester to precipitate the water-insoluble polymer. Fine polymer particles free from adhesion or agglomeration are obtained efficiently. Since any residual unreacted carboxyl-containing monomers are dissolved out in water as a precipitating solvent, the resulting powdered polymer has a reduced residual content of the unreacted monomers which may be poisonous and is therefore useful as a base resin of cosmetics or a coating resin for applications involving contact with the skin.
