EPOXY RESIN, CURABLE RESIN COMPOSITION AND CURED PRODUCT THEREOF
摘要
<p>Disclosed is a phenol aralkyl epoxy resin having a structure wherein at least a phenol or a naphthol is bound by using an aralkyl group as a linking group and a structure represented by the formula (1) below, while satisfying the condition 1 below. This epoxy resin is excellent in workability during production of a composition and is easy to control quality. Condition 1: The following relation (a) is satisfied with A being the hydroxyl equivalent (as measured in accordance with JIS K 0070) of a phenol-modified epoxy resin obtained by adding an equivalent molar amount of phenol relative to the epoxy equivalent of the epoxy resin, and B being the epoxy equivalent of the epoxy resin. 150 = 1000 × (B - A)/B = 250 (a)</p>
