Document Type and Number:
Japanese Patent JP7340151
Kind Code:
B2
Abstract:
An object of the present invention is to provide a resin composition which has excellent photocurability for various active energy rays, in particular, an active energy ray including an h-line at a wavelength of 405 nm, without inhibiting photocuring reaction in an exposure step, and can confer excellent alkaline developability in a development step, when used in the fabrication of a multilayer printed wiring board; and a resin sheet, a multilayer printed wiring board, and a semiconductor device. The resin composition of the present invention is a resin composition containing: a maleimide compound (A) containing a constituent unit represented by the formula (1), and maleimide groups at both ends of the molecular chain; a photo initiator (B1) represented by the formula (2) and/or a photo initiator (B2) represented by the formula (3); and a photo initiator (C) represented by the formula (4):
