The object of the present invention is to provide a photobase generator capable of efficiently generating amines (tertiary amines and amidine) high in catalytic activity by sensing light with a wavelength of from 350 to 500 nm (especially, from 400 to 500 nm).
The present invention is a photobase generator characterized in being represented by general formula (1) or (2).
Y+ is a quaternary ammonio group of general formula (3) to (5), and X− is a counter anion selected from among a borate anion, a phenolate anion, and a carboxylate anion.

The present invention relates to new 4-phenyl-1,3-azole derivatives having the general formula (I)
wherein R1, R2, R3, R4, X, A, B, and n are variable, in a racemic form, an enantiomeric form or any combinations thereof. These compounds exhibit affinity for cannabinoid receptors and may therefore be used as drugs to treat or prevent pathological states and diseases in which one or more of these receptors are involved. The invention also relates to pharmaceutical compositions containing said products and to the use thereof to prepare a drug.
An indole derivative represented by general formula (1). It has a potent antiestrogenic effect and hence is useful for treating estrogen-dependent diseases such as anovular infertility, prostatomegaly, osteoporosis, breast cancer, endometrial cancer and melanoma.
The photobase generator of the invention is represented by the following formula 1:
wherein Ar, R, A+ and X- are as defined in the specification. Since the photobase generator of the formula 1 absorbs ultraviolet lights of relatively long wavelength and is photolyzed to generate a strong base efficiently, a composition containing the photobase generator and an episulfide compound is easily cured by polymerization under ultraviolet irradiation.
