General formula [II] Wherein R ₄ is a hydrogen atom, a hydroxyl group, an oxy radical group, —SOR ′ ₄ , —SO ₂ R ′ ₄ (R ′ ₄ represents an alkyl group or an aryl group), an alkyl group, an alkenyl group, an alkynyl A group or —COR ″ ₄ (R ″ ₄ represents a hydrogen atom or a monovalent organic group). R ₅ , R ₆ and R ₇
Each represents an alkyl group. R ₈ and R ₉ each represent a hydrogen atom or —OCOR ″ ′ (R ″ ″ represents a monovalent organic group). R ₈ and R ₉ may together form a heterocyclic ring.
n represents the integer of 0-4. ] Y-1 Y-2 I-1 II-1 II-2
