Claim Text:
1. A hair cosmetic comprising the following components (A) to (D): (A) a (meth)acrylic silicone-based graft copolymer that is obtained by reacting the following radically polymerizable monomers (a), (b), (c), and (d) and is dissolved at a level of 50 mass % or more in 99.5% ethanol at 25° C.: (a) a compound represented by the following formula (I): (wherein Me represents a methyl group, R1 represents a hydrogen atom or a methyl group, R2 represents a linear or branched divalent saturated hydrocarbon group containing 1 to 10 carbon atoms, which optionally comprises one or two ether bonds, R3 represents a saturated hydrocarbon group containing 1 to 10 carbon atoms, and m represents any of integer of 5 to 100); (b) at least one selected from (wherein R4 represents a hydrogen atom or a methyl group, R5, R6 and R7, which are the same or different, each represents a hydrogen atom or an alkyl group containing 1 to 4 carbon atoms, X represents —O—, —NH—, —O—CH a compound represented by the following formula (III): (wherein R8 and R9, which are the same or different, each represents a hydrogen atom or an alkyl group containing 1 to 4 carbon atoms, R10 and R11, which are the same or different, each represents a hydrogen atom or an alkyl group containing 1 to 18 carbon atoms, and Z (c) a compound represented by the following formula (IV): (wherein R12 represents a hydrogen atom or a methyl group, and R13 represents a hydrogen atom or a linear or branched alkyl group containing 1 to 3 carbon atoms); and (d) a compound represented by the following formula (V): (wherein R14 represents a hydrogen atom or a methyl group, and R15 represents a hydroxyalkyl group containing 1 to 4 carbon atoms); (B) at least one film-forming polymer selected from nonionic, amphoteric, and cationic polymers; (C) a monohydric lower alcohol; and (D) at least one selected from polyalkylene glycols and sugar alcohols.
