Document Type and Number:
WIPO Patent Application WO/2019/202964
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a thermosetting resin composition that has excellent storage stability and is able to obtain, at a low temperature, a cured film having excellent durability and appearance. The thermosetting resin composition according to the present invention contains: a resin that has a specific hydroxyl group; (B) an alkyl etherified melamine resin; (C) a Lewis acid catalyst that comprises a cation comprising a metal having a Pauling electronegativity of 1.31 to 2.02, and that comprises, as a counter anion, a deprotonated protonic acid having an acid dissociation constant pKa of no more than 1.0; and (D) a solvent, wherein the solvent (D) contains a solvent (D-1) that has a Hildebrand solubility parameter value (SP value) of 18.6 to 47.9, the content of the solvent (D-1) is at least 21% by mass with respect to the total amount of the solvent (D), and within the solvent (D-1), the content of a solvent (D-S) that has a solubility of the Lewis acid catalyst (C) of at least 0.01% by mass is at least 4% by mass with respect to the total amount of the solvent (D).
