<p>A film-forming resin comprising a copolymer consisting of: (a) from 30 to 80 % by weight of a (meth)acrylamide monomer represented by the formula (1) wherein R<1> represents CH3, etc. and R<2> and R<3> represent each a hydrogen atom or a C4 - C12 alkyl group; (b) from 2 to 50 % by weight of a (meth)acrylamide monomer represented by the formula (2) wherein R<4> and R<5> represent each a hydrogen atom or a C1 - C3 alkyl group; (c) from 0 to 30 % by weight of a (meth)acrylate monomer or a (meth)acrylamide monomer represented by the formula (3) wherein R<6> represents a C2 - C3 alkyl group, R<7> and R<8> represents each CH3 or C2H5, and a represents a number of 0 or 1; and (d) from 0 to 40 % by weight of a (meth)acrylate monomer represented by the formula (4) wherein R<9> and R<10> represent each a C2 - C4 alkylene group, R<11> represents a hydrogen atom, CH3 or C6H5, and b and c represent each a number of from 0 to 50; and a hair care product containing the same: <CHEM> <CHEM> The film-forming resin of the present invention makes it possible to sustain a hair style over a prolonged period of time even under a high humidity. Further, it is excellent in shampoo-washability. When used as a hair-styling resin, it achieves an effect of giving a long-lasting and good finishing.</p> |
