<p>CARBOXYLIC ACID COMPOUND AND EPDXY RESIN COMPOSITION CONTAINING SAMEAbstractAn object of the present invention is to provide a carboxylic acid compound whichis liquid at room temperature, has a little volatility at high temperature, and affords a colorless and transparent cured product whose surface is not sticky, particularly as a curing agent for epoxy resin compositions to be used as encapsulating materials.Such a carboxylic acid compound is a carboxylic acid compound (A) obtainable by an addition reaction of a silicone compound (a) represented by the following formula(1): [err]wherein R[err] represents an alkylene group having 1 to 10 carbon atoms in total which may contain an ether group, R[err] represents a methyl group or a phenyl group, and n represents from 1 to 100 as an average value, respectively,with a compound having one or more carboxylic anhydride group in the molecule, for example, represented by the following formula (3):[err] NO FIGURE</p> |
