PHOTOSENSITIVE COMPOSITION

The present invention refers to attenuation or light irradiated number colored masking a substance such as a high-density film transmitting thick presence the nozzles less even in a case of a low energy dose curable a photosensitive composition and gives a cured article is defined to be in the, these compositions comprise photosensitive of the present invention (1) ～ (4) as disclosed is a photosensitive composition containing, radical disclosure number (A), number (C) base generation and number (B) acid generator at least 1 by the irradiation of the light active dog generates active species (H), (H) active species thereof disclosure number (A) radical is, number (B) acid generator or base generation number (C) reacts with the new active species (I) the registrant produces new active species by polymeric material (I) is performed by polymerization of (D), (I) or (H) active species thereof acid or base is characterized in that; (1) radical disclosure number (A) (2) acid generator or base generation number (C) number (B) (3) polymeric material (D) (4) number (E) colored, metal oxide powder (F) or metal powder (G).

Photobase generator

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.

Synthesis of xanthones, thioxanthones, and acridones by the coupling of arynes and substituted benzoates

The reaction of silylaryl triflates, CsF, and ortho-heteroatom-substituted benzoates affords a general and efficient way to prepare biologically interesting xanthones, thioxanthones, and acridones. This chemistry presumably proceeds by a tandem intermolecular nucleophilic coupling of the benzoate with an aryne and a subsequent intramolecular electrophilic cyclization.
