RADIATION-SENSITIVE COMPOSITION AND RECORDING MEDIUM PRODUCED THEREFROM

A radiation-sensitive composition comprising: an acid-generating compound capable of generating an acid upon exposure to radiation and represented by the formula (I): wherein X, Y and R to R have the following meanings: X and Y: independently a direct bond, C1-C18 alkylene, C1-C4 alkene, -O-R -O- (wherein R is an alkylene group having 1 to 4 carbon atoms), -NH-, -O-, -S-, -SO2-, -CO-, -COO- or -CONR - (wherein R is a hydrogen atom, C1-C18 alkyl, alkylaryl, halogenated alkyl, halogenated aryl, a halogen atom, alkoxy, phenoxy, alkylsulfonyl-oxy, halogenated alkylsulfonyl-oxy, or substituted or unsubstituted arylsulfonyl-oxy); R to R : a hydrogen atom, C1-C18 alkyl, aryl, hetero-aryl, a halogen atom, alkyl-substituted or aryl-substituted amino, alkyl-substituted or aryl-substituted amido, nitro, cyano, aldehyde, acetal, alkoxy, phenoxy, alkylsulfonyl-oxy, or substituted or unsubstituted arylsulfonyl-oxy; R : a hydrogen atom, alkyl, aryl, halogenated alkyl, halogenated aryl, halogenated hetero-aryl, alkylsulfonyl-oxy, halogenated alkylsulfonyl-oxy, or substituted or unsubstituted arylsulfonyl-oxy; a water-insoluble but aqueous alkaline solution-soluble binder; and a cross-linking compound capable of reacting with said binder in the presence of said acid to cause the binder to be cross-linked. Further, a radiation-sensitive recording medium can be obtained by forming a layer made of the radiation-sensitive composition on a substrate.
