Base-releasing composition and curable resin composition using the same

Abstract

A base-releasing composition which suppresses release of a basic compound at room temperature and rapidly releases the basic compound under predetermined conditions. The base-releasing composition includes (A) a side-chain crystalline (meth)acrylate copolymer includes (i) repeating units each derived from an ester of a C8-C32 saturated, linear primary alcohol with acrylic acid or methacrylic acid and (ii) repeating units each derived from acrylic acid or methacrylic acid, and (B) a basic compound. The amount of basic groups in the (B) basic compound is 0.01 to 1.00 mmol per 1 g of the base-releasing composition, and at least a portion of the Component (B) is included in the Component (A). A curable resin composition includes a specific 2-methylene-1,3-dicarbonyl compound in combination with the base-releasing composition.
