| abstract |
A compound of the present invention is represented by the formula (A); wherein R1 represents a hydrogen atom or a C1 to C6 alkyl group; Z1 represents a single bond, -CO-O-* or -CO-O-(CH2)k-CO-O-*; Z2 represents a single bond, *-O-CO-, *-CO-O-, *-O-(CH2)k-CO-, *-CO-(CH2)k-O-, *-O-(CH2)k-CO-O-, *-O-CO-(CH2)k-O- or -O-CO-(CH2)k-O-CO-; k represents an integer of 1 to 6; * represents a binding position to W; W represents a C4 to C36 (n+1) valent alicyclic hydrocarbon group or a C6 to C18 (n+1) valent aromatic hydrocarbon group, one or more hydrogen atoms contained in the alicyclic hydrocarbon group and the aromatic hydrocarbon group may be replaced by a halogen atom, a C1 to C12 alkyl group, a C1 to C12 alkoxy group, a C2 to C4 acyl group or -OR10; R10 represents a hydrogen atom or a group represented by the formula (R2-2); R2 represents a hydrogen atom, a group represented by the formula (R2-1) or (R2-2); n represents an integer of 1 to 3; R4, R5 and R6 independently represent a C1 to C12 hydrocarbon group; R7 and R8 independently represent a hydrogen atom or a C1 to C12 hydrocarbon group; R9 represents a C1 to C14 hydrocarbon group. |
