Document Type and Number:
WIPO Patent Application WO/2024/075651
Kind Code:
A1
Abstract:
The present invention pertains to a stabilizer which comprises: a compound (A) selected from the group consisting of compounds represented by formula (1) [in formula (1), R1, R2, R4, and R5 each independently represent a hydrogen atom, an alkyl group having 1-8 carbon atoms, a cycloalkyl group having 5-8 carbon atoms, an alkyl cycloalkyl group having 6-12 carbon atoms, an aralkyl group having 7-12 carbon atoms, or a phenyl group, each R3 independently represents a hydrogen atom or an alkyl group having 1-8 carbon atoms, X represents a single bond, a sulfur atom, or a -CH(-R13)-group (R13 represents a hydrogen atom, an alkyl group having 1-8 carbon atoms, or a cycloalkyl group having 5-8 carbon atoms), A represents an alkylene group having 1-8 carbon atoms or a *-C(=O)-R14-group (R14 represents a single bond or an alkylene group having 1-8 carbon atoms, and * represents an atomic bonding on the oxygen side), and one of Y and Z represents a hydroxyl group, an alkoxy group having 1-8 carbon atoms, or an aralkyloxy group having 7-12 carbon atoms, and the other of Y and Z represents a hydrogen atom or an alkyl group having 1-8 carbon atoms] and compounds represented by formula (2) [in formula (2), R6 and R8 each independently represent a hydrogen atom, a methyl group, or an alkyl group having 5-8 carbon atoms, each R7 independently represents a hydrogen atom or a hydroxyl group, and each R9 independently represents a hydrogen atom or a -C15H25-31 group, but at least one of R6, R7, R8, or R9 is not a hydrogen atom]; and a compound (B) represented by formula (3) [in formula (3), R10, R11, and R12 each independently represent a hydrogen atom, an alkyl group having 1-12 carbon atoms, or an arylalkyl group having a total of 7-20 carbon atoms, but at least one of R10, R11, and R12 is not a hydrogen atom]. In the stabilizer, the contained amount of the compound (B) with respect to 100 parts by mass of the compound (A) is 0.01-50 parts by mass.
