Patent ID: 8476444

Claim:
A base generator which is represented by the following chemical formula (1) and generates a base by exposure to electromagnetic radiation and heating: wherein R 1 and R 2 are a combination of hydrogen and a saturated or unsaturated cycloalkyl group or independently a monovalent organic group, and R 1 and R 2 may be bound to form a cyclic structure which may contain a heteroatom; R 3 , R 4 , R 5 and R 6 are independently hydrogen, halogen, a hydroxyl group, a nitro group, a nitroso group, a mercapto group, a silyl group, a silanol group or a monovalent organic group and may be the same or different; two or more of R 3 , R 4 , R 5 and R 6 may be bound to form a cyclic structure which may contain a heteroatom; at least one of R 3 , R 4 , R 5 and R 6 is halogen, a hydroxyl group, a nitro group, a nitroso group, a mercapto group, a silyl group, a silanol group or a monovalent organic group, or two or more of R 3 , R 4 , R 5 and R 6 are bound to form a condensed ring together with a benzene ring to which R 3 , R 4 , R 5 and R 6 are bound.
