-1- Abstract The present invention is directed to a novel compound which has both an alpha-ketoester group and a polymerizable double bond, a process for the production thereof, a polymer prepared therefrom and a curable composition containing the same. The compound has the formula (I); A - X - COCOOR1 (I) [wherein A represents a C1 - C18 alkenyl, alkynyl, alkenylaryl or alkenylaralkyl group, or a group represented by; Image (wherein R2 and R3 are the same or different and each represent a hydrogen atom, or a C1- C5 alkyl group, Y represents an oxygen atom or -NR4-, in which R4 represents a hydrogen atom or a C1 - C5 alkyl group, n is an integer of 1 to 5, m is an integer of 1 to 10 and ? is 0 or an integer of 1 to 20); R1 represents a hydrogen atom, a C1 - C5 alkyl group or an aryl group; and X represents an oxygen atom, a sulfur atom, -COO- or -NR5-, in which R5 is a hydrogen atom or a C1 - C5 alkyl group, provided that if Y is present, X is not -NR5-.] The polymers and curable compositions of the present invention are suitable for use in the field of coatings and adhesives.
