Acid- and radical-generating agent and method for generating acid and radical

Abstract

It is a subject of the present invention to provide an acid- and radical-generating agent which has high sensitivity to an active energy ray having a wavelength of around 300 to 450 nm, and can exert both high acid-generating performance and high radical-generating performance, and has heat resistance; and a method for generating an acid and a radical. The present invention relates to a compound represented by the general formula (A); an acid- and radical-generating agent comprising the compound; and a method for generating an acid and a radical: wherein n pieces of Reach independently represent an alkyl group, which may have a specific functional group in the chain, or in which a hydrogen atom may be substituted by a halogen atom; an alkoxy group, in which a hydrogen atom may be substituted by a halogen atom; an aryl group or an aryloxy group, in which a hydrogen atom may be substituted by a halogen atom, an alkyl group or a haloalkyl group; or an arylalkyl group or an arylalkyloxy group, in which a hydrogen atom may be substituted by a halogen atom, an alkyl group or a haloalkyl group; n pieces of Rand Reach independently represent a hydrogen atom, an alkyl group or an alkoxycarbonyl group; Rto Reach independently represent a hydrogen atom, a halogen atom, an alkyl group, an alkoxy group, an alkenyl group, an aryl group, an alkoxycarbonyl group, a dialkylamino group or a nitro group; Y represents an oxygen atom, a sulfur atom, or a carbonyl group; n pieces of Z each independently represent a sulfonyl group or an alkoxyphosphoryl group; n represents 1 or 2.
