<p>PURPOSE:To obtain the title material improved in resistance to a highly concentrated aqueous alkaline solution by mixing a glycidyl compound with a compound having a glycidyl-reactive substituent and a specified compound having a heterocyclic structure. CONSTITUTION:100 pts.wt. compound having at least one glycidyl group in the molecule, desirably a compound of the formula (wherein R<1>, R<2>, R<4> and R<7> are each H or methyl; R<3>, R<5> and R<6> are each H, 1-12C alkyl or an aromatic group; R<8> is phenyl or a pyrrolidone residue; l is 1 or greater; and m, n and k are each 0 or greater) is mixed with 1-100 pts.wt. compound having a glycidyl- reactive substituent [e.g. trimellitic acid (anhydride)], desirably a polyvalent compound, 0.01--1 pt.wt. compound having a heterocyclic structure containing a sec. nitrogen atom and/or a tert. nitrogen atom, desirably an imidazole derivative and optionally a solvent, a surfactant, a silane coupling agent, etc.</p> |
