In the formula, m and n are independently 0 or 1, p is an integer of 0-4, and s is an integer of 0-4. Y represents an oxygen atom, etc. R1 represents a predetermined monovalent aliphatic hydrocarbon group. R2 represents a predetermined alkoxy group, etc. R3 represents a predetermined divalent aliphatic hydrocarbon group which may have a substituent and may contain a heteroatom in a carbon chain. R4 represents a predetermined monovalent aliphatic hydrocarbon group. R5 represents a hydrogen atom, a predetermined alkoxy group which may have a substituent, etc. R6 represents a hydrogen atom or a monovalent aliphatic hydrocarbon group. R7 and R8 both represent a hydrogen atom or are integrated to represent a methylidene group.
