Abstract

A novel tris(formylphenyl) according to the following general formula and polynuclear phenol derived therefrom, which are useful as a material for heat resistant materials, material for photosensitive resist compositions, epoxy resin material or hardener, developer or anti-fade agent for thermosensitive recording materials, or sterilizer, fungicide, antioxidant, etc:

In the formula, Y represents a hydrogen atom or —R₂COOR₃ group, R₂ represents a monocyclic or condensed cyclic aromatic hydrocarbon group with a carbon atom number of 6 to 15 or an aliphatic hydrocarbon group with a carbon atom number of 1 to 8 that may have in its main chain a monocyclic or condensed cyclic aromatic hydrocarbon group with a carbon atom number of 6 to 15, and R₃ represents a hydrogen atom or alkyl group with a carbon atom number of 1 to 6. R₁s may be the same or different and respectively represent a hydrogen atom, alkyl group with a carbon atom number of 1 to 8 or alkoxyl group with a carbon atom number of 1 to 8. R_B and R_C may be the same or different, where R_A, R_B and R_C respectively represent a hydrogen atom or alkyl group with a carbon atom number of 1 to 6 and n and m are respectively an integer of 0 or 1 to 3.
