| abstract |
The present invention relates to a reaction product of (a) an epoxy compound having at least two epoxy groups in a molecule and (b) a polybasic carboxylic acid, or (a) an epoxy compound having at least two epoxy groups in a molecule, and (b) a polybasic A polycarboxylic acid resin obtained by reacting a reactant with a carboxylic acid and (c) a polybasic carboxylic acid or an anhydride thereof is further contained, and the resin composition [B] is an ethylenically unsaturated bond. It is an object of the present invention to provide a photosensitive resin composition comprising an addition polymerizable compound having at least one of the above, a [C] photopolymerization initiator, and a [D] solvent. These resin compositions and its hardened | cured material are used suitably as a photosensitive resin composition, In particular, even if it is the coloring photosensitive resin composition containing a pigment, high resolution can be obtained.n n n n Resin composition |
