AQUEOUS COATING LIQUID, GAS BARRIER COATING LAYER AND MULTILAYER STRUCTURE OBTAINED BY USING THE AQUEOUS COATING LIQUID

摘要

PROBLEM TO BE SOLVED: To provide an aqueous coating liquid by which coating layer excellent in gas barrier performance in high humidity can be obtained.;SOLUTION: Zirconium ammonium carbonate is blended as a cross-linking agent into PVA-based resin that contains the structural unit shown by general formula (1) [In the formula, R¹ R², and R³ each independently show hydrogen atoms or organic groups, X shows a single bond or a joining chain, and R⁴, R⁵ and R⁶ each independently show hydrogen atoms or organic groups].;COPYRIGHT: (C)2014,JPO&INPIT
