Claim:
A composition comprising a polymer compound A containing a repeating unit represented by the formula (1) and a polymer compound B containing a repeating unit represented by the formula (2): wherein R 1 and R 2 each independently represent a hydrogen atom, a fluorine atom, an alkyl group, an alkoxy group, an alkylthio group, an aryl group, an aryloxy group, an arylthio group, an arylalkyl group, an arylalkoxy group or an arylalkylthio group, and the hydrogen atom contained in these groups may be substituted with a fluorine atom, and wherein R 3 and R 4 each independently represent a hydrogen atom, a fluorine atom, an alkyl group, an alkoxy group, an alkylthio group, an aryl group, an aryloxy group, an arylthio group, an arylalkyl group, an arylalkoxy group or an arylalkylthio group, and the hydrogen atom contained in these groups may be substituted with a fluorine atom; p represents an integer of 2 to 10; a plurality of R 3 (s) may be the same or different; and a plurality of R 4 (s) may be the same or different, wherein the polymer compound A includes a block containing one or more repeating units selected from a repeating unit represented by the formula (12), a repeating unit represented by the formula (13) and a repeating unit represented by the formula (14): wherein R 1 and R 2 have the same meanings as defined above, and wherein R 7 , R 8 , R 9 , R 10 , R 11 , R 12 , R 13 and R 14 each independently represent a hydrogen atom, a fluorine atom, an alkyl group, an alkoxy group, an alkylthio group, an aryl group, an aryloxy group, an arylthio group, an arylalkyl group, an arylalkoxy group or an arylalkylthio group, and the hydrogen atom contained in these groups may be substituted with a fluorine atom, and R 33 , R 34 , R 35 and R 36 each independently represent a hydrogen atom, a fluorine atom, an alkyl group, an alkoxy group, an alkylthio group, an aryl group, an aryloxy group, an arylthio group, an arylalkyl group, an arylalkoxy group or an arylalkylthio group; wherein R 1 , R 2 , R 33 , R 34 , R 35 and R 36 have the same meanings as defined above, and wherein R 15 , R 16 , R 17 , R 18 , R 19 , R 20 , R 21 , R 22 , R 23 and R 24 each independently represent a hydrogen atom, a fluorine atom, an alkyl group, an alkoxy group, an alkylthio group, an aryl group, an aryloxy group, an arylthio group, an arylalkyl group, an arylalkoxy group or an arylalkylthio group, and the hydrogen atom contained in these groups may be substituted with a fluorine atom; wherein R 1 , R 2 , R 33 , R 34 , R 35 and R 36 have the same meanings as defined above, and wherein R 25 , R 26 , R 27 , R 28 , R 29 , R 30 , R 31 and R 32 each independently represent a hydrogen atom, a fluorine atom, an alkyl group, an alkoxy group, an alkylthio group, an aryl group, an aryloxy group, an arylthio group, an arylalkyl group, an arylalkoxy group or an arylalkylthio group, and the hydrogen atom contained in these groups may be substituted with a fluorine atom.
