Patent ID: 8137892

Claim:
The photobase generator comprising a compound having a nitrogen atom and a conjugated double bond, wherein the compound comprises at least either of compounds represented by the following general formulas (3) and (4); wherein R 1 and R 2 each independently represent a hydrogen atom, an alkyl group, an alkenyl group, a cycloalkyl group, an aralkyl group, or an aryl group; R 3 , R 4 , R 5 , R 6 and R 7 each independently represent a hydrogen atom, a carboxyl group, an alkoxycarbonyl group, a cyano group, a formyl group, an acyl group, a nitro group, a nitroso group, an alkyl group, an alkenyl group, a cycloalkyl group, an aralkyl group, an aryl group, a hydroxy group, a mercapto group, an alkylthioether group, an alkoxy group, a halogen group, or an amino group; R 1 , R 2 , R 3 , R 4 , R 5 , R 6 and R 7 , at least two of which may bond together to form a saturated or an unsaturated ring, may each independently be substituted with a monovalent group formed by removing a hydrogen atom from the compound represented by the formula (3) or (4); and Z represents an oxygen atom or a sulfur atom; wherein R 1 represents a hydrogen atom, an alkyl group, an alkenyl group, a cycloalkyl group, an aralkyl group, or an aryl group; R 3 , R 4 , R 5 , R 6 , R 7 and R 8 each independently represent a hydrogen atom, a carboxyl group, an alkoxycarbonyl group, a cyano group, a formyl group, an acyl group, a nitro group, a nitroso group, an alkyl group, an alkenyl group, a cycloalkyl group, an aralkyl group, an aryl group, a hydroxy group, a mercapto group, an alkylthioether group, an alkoxy group, a halogen atom, or an amino group; R′, R 2 , R 3 , R 4 , R 5 , R 6 , R 7 and R 8 , at least two of which may bond together to form a saturated or an unsaturated ring, may each independently be substituted with a monovalent group formed by removing a hydrogen atom from the compound represented by the formula (3) or (4).
