Abstract

The present invention provides an active energy ray solidification type resin composition using a reactivity compound with a fire retardance and a condensate thereof. The active energy ray solidification type resin composition has a high fire retardance, a superior light sensitivity, a solidifying film of the composition has a developing character, a solidifying character, a closing character, a HAST resistance, a pliability and the like, and is specially suitable for a light-sensitive resin composition for a welding resistance layer and a light-sensitive resin composition for a flexible printing substrate. The active energy ray solidification type resin composition contains a phosphine oxide (A) represented by formula (1), a reactivity compound (B) having more than two active energy ray reactivity functional groups within a molecule and a optical polymerization initiator (C), in the formula (1), R represents a hydrogen atom or methyl.

Description

technical field [0001] The present invention aims at flame retardancy of polymer materials, and relates to an active energy ray-curable resin composition using a phosphine oxide compound that is a reactive compound that can be polymerized into various polymer materials. Examples of its use include materials for film formation, solder resists in the production of printed (wiring circuit) substrates, other protective layer materials capable of alkali development, adhesives, lenses, displays, optical fibers, optical waveguides, holograms, and the like. Background technique [0002] Attempts to impart flame retardancy to moldings, film-forming materials, and the like have been widely carried out. Conventionally, flame-retardant materials using halogen-based compounds typified by bromine compounds have been widely used, but in recent years due to an increase in environmental concerns, the use of these compounds has begun to be avoided. As a substitute for these compounds, flame ...
