ABSTRACT:
The invention provides a novel adamantane derivative useful as a monomer for producing functional resins such as photosensitive resins particularly for use in lithography, and a method for producing the derivative. The adamantane derivative has a structure represented by formula (I-a) and the method for producing the adamantane derivative employs a corresponding adamantane derivative serving as a starting material. In formula (I), R1represents H, CH3, or CF3; R2arepresents a C1 to C30 alkyl group or a hydrocarbon group containing a C3 to C30 cycloalkyl group or a C6 to C30 aryl group, the alkyl group or the hydrocarbon group having a hetero atom; each of X1and X2represents O or S; Y represents a C1 to C10 alkyl group, a halogen atom, OH, or SH, or two Ys are linked to form ═O or ═S; k represents an integer of 0 to 14; and each of m and n is an integer of 0 to 2.
