PURPOSE:To obtain the above composition excellent in rapid curability, curing characteristics and useful for a coating, an adhesive or the like, by using a reaction product of 1,2,3,4-butanetetracarboxylic acid or its anhydride with a specified compound as a curable component. CONSTITUTION:A curable component is obtained by reacting 1,2,3,4- butanecarboxylic acid or its anhydride with a compound having at least one ethylenically unsaturated group and an OH or glycidyl group (e.g., 2- hydroxyethyl acrylate or glycidyl acrylate) in the presence of, optionally, 0.01-10wt.% catalyst (e.g., triethylamine), 0.005-0.1wt.% polymerization inhibitor (e.g., p-methoxyphenol) and a solvent (e.g., toluene). 100pts.wt. curable component is mixed with, optionally, 100pts.wt. or below reactive diluent (e.g., 2- ethylhexyl acrylate), 0.01-20pts.wt. polymerization initiator (e.g., benzoin ethyl ether), and 0.01-20pts.wt. sensitizer (e.g., triethylamine) to obtain the title composition. |
