Abstract
The present invention provides a photopolymerizable composition for a color filter containing an addition-polymerizable compound having at least one ethylenically unsaturated double bond, a photopolymerization initiator and the oxide of at least one metal selected from the group consisting of Cu, Fe, Mn, Cr, Co, Ni and Al and being substantially free from any halogen atom; and a process for producing a color filter. The photopolymerizable compositions for a color filter makes it possible to form a color filter having good heat resistance and high electrical insulation resistance and have high storage stability.
