摘要:
A visible light curable resin composition containing a photocurable resin, a photoreaction initiator and a photosensitizer having the formula (1). The composition has a very high sensitivity to a general-purpose visible light laser, so that a high-speed scanning exposure is possible by the laser, and an extremely fine high resolution can be obtained. In addition, the composition can be used for coating or printing under safelight irradiating conditions and under bright circumstantial conditions without any thickening of the composition, and hence the composition can exert excellent noticeable effects in points of safe operativity, operational efficiency and the stability of products. Formula (1) is as follows: ##STR1## wherein rings X.sub.1 and X.sub.2 are each an optionally substituted pyrrole ring; Y is H, CN, optionally substituted alkyl, aralkyl, aryl, heteroaryl or alkenyl group; and Z.sub.1 and Z.sub.2 are halogen, optionally substituted alkyl, alkoxy, alkylthio, aralkyl, aralkyloxy, aryl, aryloxy, arylthio, heteroaryl, heteroaryloxy or heteroarylthio group, provided that at least one of substituents on the pyrrole rings X.sub.1 and X.sub.2, groups Z.sub.1 and Z.sub.2 is the alkoxy, aralkyloxy or aryloxy group.
