摘要:
A base precursor for heat-developable photosensitive material is disclosed. The precursor is comprised of a compound represented by general formula (I) or (II):(R--C.tbd.C--CO.sub.2 H).sub.x.B (I)R--C.tbd.C--CO.sub.2 H).sub.2.B.sub.y (II)The substituents within the general formulae are defined within the specification. The use of this novel base precursor makes it possible to obtain a material which is very stable at normal temperatures and which smoothly decomposes under heating at 80.degree. C. or higher in order to release a basic constituent.
