Patent ID: 7271297

Claim:
A vinyl ether compound represented by following Formula (4): wherein ring Z is any one of cyclic groups represented by following Formulae (6) through (12): wherein X 2 , X 3 , X 4 , X 5 , X 6 , X 7 , and X 8 are each a substituent combined with an atom constituting each ring and are each a halogen atom, an alkyl group, a haloalkyl group, an aryl group, a hydroxyl group optionally protected by a protecting group, a hydroxymethyl group optionally protected by a protecting group, an amino group optionally protected by a protecting group, a carboxyl group optionally protected by a protecting group, a sulfo group optionally protected by a protecting group, an oxo group, a nitro group, a cyano group, or an acyl group optionally protected by a protecting group, b, c, d, e, f, g, and h are each an integer of 0 or more, wherein when b, c, d, e, f, g or h is 2 or more, the substituents in the parentheses may be the same or different; and p, q, and r are each an integer of from 0 to 3; W is a divalent hydrocarbon group; R 2 , R 3 , and R 4 are the same or different and are each a hydrogen atom or an organic group selected from the group consisting of a halogen atom, a hydrocarbon group, a heterocyclic group, a substituted oxycarbonyl group, a carboxyl group, a substituted or unsubstituted carbamoyl group, a cyano group, a nitro group, a sulfur acid group, a sulfur acid ester group, an acyl group, an alkoxy group, a N,N-di-substituted amino group, and groups each comprising two or more of these groups combined with each other; n is 0 or 1; and m is an integer of from 1 to 8, wherein groups in the parentheses are the same or different when m is 2 or more; wherein when ring Z is the cyclic group represented by Formula (6), m is 2 or more; wherein when ring Z is the cyclic group represented by Formula (6), m is 2 or 3; or b is an integer of from 1 to 3; or W is a divalent hydrocarbon group selected from the group consisting of an alkenylene group, an cycloalkylene group and a cycloalkylidene group; and wherein c is 1 or more when p is 0 or 1, and X 3 is a group other than hydroxyl group when p is 0 and c is 1 in Formula (7).
