PURPOSE:A polymerizable composition capable of forming a flexible coat excellent in adhesion to a metal, which is composed of a bisphenol F-type epoxy diacrylate and a specified reactive diluent. CONSTITUTION:A reactive diluent (B), of formula I (wherein R1 is H or methyl; R2 is a 5-20C cyloalkyl, phenyl, tetrahydrofurfuryl or a 5-20C alkyl containing said groups), formula II [wherein R2 is a 2-40C alkylene; R4 is a 2-40C alkyl or alkylene (wherein the sum of carbon numbers in R2 and R4, <=40)], formula III (wherein R5 is a 1-20C alkyl, vinyl, aryl or alkoxyalkyl), or formula IV [wherein R6 is a 2-12C alkylene, cycloalkylene or phenyl; X1-Xn are 2-6C (monohydroxy) alkylene; n is an integer of 0-5), is compounded with a bisphenol F-type epoxy diacrylate (A). A crosslinkable monomer such as 1,3-butanediol diacrylate may be additionally compounded. |
