1. A curable resin composition consisting of a high molecular weight compound having a weight average molecular weight of
70,000 to 300,00 and a vinyl compound of the formula (1),
 wherein the high molecular weight compound is at least one compound selected from the group consisting of a styrene isoprene
styrene copolymer, a hydrogenated styrene butadiene styrene copolymer, a hydrogenated styrene isoprene styrene copolymer and
a hydrogenated styrene (butadiene/isoprene) styrene copolymer, wherein the styrene content in the high molecular weight compound
is from 20 to 65% by weight and the weight ratio of the vinyl compound of the formula (1): the high molecular weight compound
is 30:70 to 70:30,
R1, R2, R3, R4, R5, R6 and R7 are the same or different and represent a hydrogen atom, a halogen atom, an alkyl group or a halogenated alkyl group,
—(O—X—O)— represents a moiety of the formula (2) or the formula (3) or represents at least two kinds of moieties of the formula
(2) and/or the formula (3),
 in which R8, R9, R10, R14 and R15 are the same or different and represent a halogen atom, an alkyl group having 6 or less carbon atoms or a phenyl group and
R11, R12 and R13 are the same or different and represent a hydrogen atom, a halogen atom, an alkyl group having 6 or less carbon atoms or a

phenyl group and A is a linear, branched or cyclic hydrocarbon having 20 or less carbon atoms,
—(Y—O)— represents a moiety of the formula (4) or a random arrangement of at least two kinds of moieties of the formula (4),
 in which R24 and R25 are the same or different and represent a halogen atom, an alkyl group having 6 or less carbon atoms or a phenyl group and
R26 and R27 are the same or different and represent a hydrogen atom, a halogen atom, an alkyl group having 6 or less carbon atoms or a
phenyl group,
Z represents an organic group having at least one carbon atom which may contain an oxygen atom, a nitrogen atom, a sulfur
atom and/or a halogen atom,
each of a and b is an integer of from 0 to 30, provided that at least one of a and b is not 0, and each of c and d is an integer
of 0 or 1.
