摘要： The invention relates to a method for efficiently producing β-mercaptocarboxylic acids using a solid acid catalyst such as zeolite, which product corresponds to respective starting materials selected from α, β-unsaturated carboxylic acids (α, β-unsaturated carboxylic acid, a, β-unsaturated carboxylic acid ester, ex, β-unsaturated amide, a, β-unsaturated aldehide and α, β-unsaturated ketone) and hydrogen sulfides (hydrogen sulfide, sulfide salt and hydrosulfide salt), wherein a solvent compatible with water is used in the reaction. According to the invention, β-mercaptocarboxylic acids which are useful as additives in synthetic materials for pharmaceutical or agricultural agents and in polymer compounds can be industrially produced efficiently by using easily available a, β-unsaturated carboxylic acid (such as crotonic acid) at high yield.

摘要： Disclosed is an agent for permanent hair waving that can realize permanent hair waving even in the neutral to weakly acidic pH range in which irritation particularly to the skin is not significant. The agent for permanent hair waving includes at least one heterocyclic mercapto compound represented by formula (1): wherein R1 and R2 each independently represent a hydrogen atom or an optionally substituted alkyl group having 1 to 5 carbon atoms; X represents -O-, -S-, -NH-, or -NR3-; R3 represents an alkyl group having 1 to 5 carbon atoms; n is an integer of 0 to 2; and, when n is 2, group SH may be attached to any carbon atom of an alkylene group having 2 carbon atoms.

摘要： There is provided an adhesive agent exhibiting high adhesive strength to polyolefin. An adhesive agent contains a chloroprene copolymer latex containing a chloroprene copolymer (A) and a metal oxide (B). The chloroprene copolymer (A) is a copolymer of a monomer group containing chloroprene (A-1), α,β-unsaturated carboxylic acid (A-2), and 2, 3-dichloro-1,3-butadiene (A-3). The chloroprene copolymer (A) has a tetrahydrofuran-soluble component soluble in tetrahydrofuran and the weight average molecular weight of the tetrahydrofuran-soluble component is 80000 or more and 140000 or less. When the amount of the metal oxide (B) based on 100 parts by mass of the chloroprene copolymer (A) is defined as Y part(s) by mass and the weight average molecular weight of the tetrahydrofuran-soluble component is defined as X, the content of the metal oxide (B) satisfies Formula: -1.2 × X/100000 + 1.6
