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.
揭示了一种用于热可发展感光材料的基础前体。该前体由一种由通式(I)或(II)表示的化合物组成:(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)。通式中的取代基在规范中有定义。使用这种新颖的基础前体可以获得一种在常温下非常稳定且在80摄氏度或更高温度下平稳分解以释放碱性成分的材料。
