NEW MATERIAL:A compound expressed by formula I [Z is -R1 (R1 is alkyl or alkoxy), =COR1, -SO2R1, -COOM (M is H, alkali metal ion or ammonium ion), -CN, -NO2, etc.; m is ≤4].
EXAMPLE: 1,3-Bis-[2-(2-azidebenzoyl)ethenyl]benzene.
USE: A light crosslinking agent for heat resistant photosensitive resin exhibiting excellent solubility to various kind of solvents as well as capable of readily crosslinking by light, heat, radical and anion.
PREPARATION: 1mol isophthalic dialdehyde or (substituted)isophthalic dialdehyde and 2W3mol O-azideacetophenone are dissolved in a mixed solvent such as THF and methanol and the isophthalic dialdehyde is reacted with the O- azideacetophenone at 0W40°C by adding an alkali water solution such as NaOH as a catalyst to provide the aimed compound expressed by the formula.
